Did the Supreme Court Just Kill Comparison Shopping Engines?

No doubt most online marketers didn't lose much sleep when they heard that the Supreme Court was going to hear a case called Leegin Creative Leather Products v. Kay's Kloset. Today's decision, however - overruling legal precedence that has stood for almost 100 years - should wake some marketers from their slumber. Let me explain why.

Prior to today's Leegin ruling, the concept of "minimum advertised prices" or "MAP" was illegal under US anti-trust law. In other words, Sony couldn't send a letter to all of its vendors telling them what they could sell a Sony product for. They could set a "manufacturer's suggested retail price" - better known as a MSRP - but they couldn't prevent vendors from choosing to sell below the MSRP.

And in fact, as consumers, we are all accustomed to seeing advertisements proclaiming "25% off MSRP!" or "Save 40% off all Best Sellers!" Who in their right mind, after all, would go into a car dealer and actually pay the sticker price listed on the car, right?

In reality, a lot of manufacturers have been preventing vendors from selling at below MAP. For example, open any photography magazine and you'll see a lot of products that say "call for our lowest price." This is a clear indication that the vendor is selling below what he is suppose to be selling the product for and doesn't want to risk losing a relationship with the manufacturer.

At the same time, manufacturers have understood that setting a MAP was illegal, so it was often difficult to actually punish any renegade vendor who broke MAP. In fact, a friend of mine told me that one of his competitors appeared to be purposely and flagrantly violating MAP in the hopes of getting cut off by the manufacturer and thus having grounds for a very profitable lawsuit.

Today, however, the Supreme Court has made MAP legal. To quote the Court's opinion:

"Minimum resale price maintenance can stimulate interbrand competition--the competition among manufacturers selling different brands of the same type of product--by reducing intrabrand competition--the competition among retailers selling the same brand. See id., at 51-52. The promotion of interbrand competition is important because "the primary purpose of the antitrust laws is to protect [this type of] competition." Khan, 522 U. S., at 15. A single manufacturer's use of vertical price restraints tends to eliminate intrabrand price competition; this in turn encourages retailers to invest in tangible or intangible services or promotional efforts that aid the manufacturer's position as against rival manufacturers. Resale price maintenance also has the potential to give consumers more options so that they can choose among low-price, low-service brands; high-price, high-service brands; and brands that fall in between."

The consequences of this decision on the online commerce world could be substantial. Here are the online players who stand to be most impacted by the decision:

1. Comparison Shopping Engines (CSEs): Imagine what happens to comparison shopping engines if, well, there are no prices to compare. I guess they just become "shopping engines?" In fact, the likely outcome would be that the comparison engines would become nothing more than repositories for consumer satisfaction ratings. Since the price would be the same across all vendors, the user would simply need to sort the vendors based on the number of positive reviews.

Of course, in such a scenario, I can't imagine too many vendors with low ratings wanting to stick around for long on the CSEs, nor would it be likely that poorly reviewed vendors would get too many clicks in the first place.

The end result, then, for the CSEs seem pretty bleak - less utility to consumers and fewer paying vendors.

2. Small Online Merchants: New online vendors won't fare much better in the new MAP world. Forbes had a good piece on this point today, noting "opponents [of the ruling] argue that it will serve to raise prices, which will prevent small retailers--particularly those who are trying to break into burgeoning markets on the Internet--from being able to compete with established retailers."

Imagine how big Overstock.com would be today if they had not been allowed to sell at deeply-discounted prices. Any new merchant looking to establish a foothold in a market by underselling the competition is in trouble. Indeed, the Consumers Union issued a press release today noting: "The emergence of Wal-Mart and Amazon.com can be directly traced to the ban on [MAP]. Unfortunately, today's ruling may very well serve to prevent The Next Big Thing in retailing.

3. eBay: In many ways, eBay is at the center of the storm for this ruling: it owns Shopping.com - a leading comparison shopping engine - and a good chunk of its core business comes from vendors selling "buy it now" items on eBay below MAP. In a way, you could say that eBay's entire business model is based on helping consumers find ways around manufacturer's minimum prices. This could be a huge blow to that model.

4. Google: Of course it is silly to talk about any issue impacting the Internet economy without discussing Google. I actually think that this ruling won't impact Google one way or the other, simply because much of Google's revenue comes from advertising that is not price-sensitive. For example, most Google AdWords ads make murky claims about "save 50% or more" but these claims will continue regardless of this ruling.

To put it another way, eBay and Shopping.com base their value proposition on price, Google bases it's value proposition on "relevancy", which is not always price-related.

On the other hand, Google has been gradually trying to bring Google Base front and center in their search results and company strategy. If it is true that this ruling hurts comparison shopping engines, Google Base may not be as lucrative a strategy as Google once hoped.

5. Web 2.0: Amazingly, this ruling may actual help Web 2.0 companies develop a profit model! Wow! Insofar as many Web 2.0 companies revolve around consumer opinion (Yelp, blog sites, StumbleUpon, etc), the gradual decline in the importance of price may make sites that capture masses of consumer opinion the de facto destination for shoppers looking to choose between different vendors.

And unlike CSEs, which tend to have stodgy surveys as their proxy for consumer opinion, Web 2.0 companies tend to get much more mainstream and thorough opinions from their loyal users. I can envision some sort of affiliate revenue-sharing model where the 2.0 company stays out of endorsing any one vendor but makes a few bucks on any sales that result from a user's reviews.

Over the next 3-6 months, I predict you will be hearing a lot more about this case. And after reading this post, you won't be too surprised when eBay buys Yelp either.

Five Online Marketing Blogs That Don't Suck

I'm really sick and tired of the so-called 'leading' online marketing blogs that don't seem to be anything more than a combination of Google press releases and links to news stories. There was a time when the most popular online marketing blogs truly deserved their readership; they were written by marketing experts who really explored the strategy and science behind online marketing.

As blogging has gone mainstream, however, the innovators were either pushed out, or simply decided that it was easier to maintain their popularity by spewing out bland repetition multiple times a day than it was to write a few thoughtful pieces a week.

To wit, one of my once-favorite bloggers - John Batelle - was once a 'must read' every time he posted anything. Looking at his last four posts this evening, however, I find:


I really wish I could say that this was an anomaly for John, but it's not - perhaps the strain of publishing a book and starting a company has gotten to him, but this is one of many examples of once outstanding bloggers who have totally jumped the shark.

Trying to stay a little more positive, I thought I'd share a few online marketing blogs that - at least so far - are still reliably good at posting independent, thoughtful, and useful commentary and analysis of the industry. I'd like to think my blog falls into that camp (though I am not including it on the list), and I hope that if you like my blog, you'll subscribe to these as well - we need to encourage legitimate writers to continue to ply their trade!

Here they are:

  • Traffick.com by Andrew Goodman. This guy has been around a long time, and yet he continues to impress me with his insight into search engine marketing.
  • Cre8pc on Usability by Kim Krause. Well-written posts on usability.
  • ComparisonEngines.com by Brian Smith. Brian has never taken advertising on his site (well, other than promoting his own product, SingleFeed) and really tries to write posts with the veracity of a real-life journalist.
  • DMConfidential by "Editor." The anonymous author of many posts on this site is a true-insider in the world of online lead generation. He (or she, but not really) sees trends months before most.
  • SearchMarketingStandard by Andrey Milyan and Boris Mordkovich. In addition to putting out a decent magazine on SEM, these guys are true thinkers about trends in search, and their blogs reflect that.

There are several others I could include on this list - a few of which you'll find on the blogroll to the right. If you think I missed your's, let me know and I'll include it in the next list.

Are You a Dumb Grasshopper?

Just a few weeks ago, I wrote a post about Google's very smart decision to provide more transparency into their listings. In that post, I wrote

Google has led the charge toward PPC transparency. They make it easy to bundle Google Analytics with your paid search campaign, they offer conversion tracking, negative keywords, site exclusion, and most recently "search query" and "placement" results (so you can block bad AdSense publishers and bad broad-match keyword extensions).This is not Google's attempt at advertiser altruism - it's a smart, calculated business move. If you have the best traffic, you should flaunt it. And that's what Google is doing.
Normally, when Google does something it's competitors make a point of following, albeit usually in a disjointed and blundering fashion. For example, when Google announced Gmail was free with unlimited storage, Yahoo quickly reversed course and offered free storage for Yahoo Mail (I believe at the time they were gradually increasing the pricing for Yahoo Mail's "premium service"). Similarly, when Google launched AJAX maps, it wasn't long until AJAX became the programming language of choice among all other map companies.

With respect to transparency, however, Google's role as Pied Piper has had mixed results. On the one hand, Google's search competitors have done a very good job of matching Google step-for-step.

For Yahoo (f/k/a Overture) this has resulted in a major push toward getting people to download Yahoo Conversion Tracking and Yahoo Analytics. MSN AdCenter has also started to provide some very cool transparency tools. I am particularly impressed with some of the stuff they have in their AdLab, which for whatever reason, reminds me of the Bat Cave. Check out MSN's "commercial intent" query in their lab, it is pretty cool.

What's amazed me, however, is how little the Comparison Shopping Engines (CSEs) have embraced this race toward transparency. I recently had two encounters with major CSEs that
drill this point home.

In both cases, my accounts suddenly got reams of traffic. And not just any traffic - bad, non-converting traffic. For example, this weekend, one of my accounts - which had been averaging almost exactly 100 clicks per day and making a profit - suddenly got 5000 clicks in one day, with a conversion rate of about .25%. Needless to say, this cost me a lot of money. A few months ago, on another large CSE, the same thing happened - thousands of clicks, out of nowhere, with no conversions.

Bear in mind, this has happened to me on all the search engines as well. In each case, I document the issue, send it off to my rep and usually end up getting some or all of my money back.

In the case of the CSEs, however, the response has been exactly the opposite. After my sudden bad traffic spike a few months ago, my rep at the CSE told me that I was "paying for clicks and not conversions." The only remedy I had was to set a monthly maximum budget and hope for the best. "Bid for overall profitability, don't worry about losses from one day to another" was the other advice I was given.

And today when I talked to my rep at the other CSE, I was told that one of their partners had run a promotion for a product on the partner's home page. Moreover, because the CSE did not negotiate any sort of "bad click credit" with the partner, it would therefore be impossible for me to negotiate a bad click credit with the CSE. In other words, they were passing the losses on to me. In one day, any profit I had for the month was wiped out. Doesn't really make me excited about continuing my campaign with them.

Even more amazingly, the majority of CSEs don't allow you to place product-level bids, none that I know of have reporting APIs, most don't have daily budget caps, and some don't even have UIs that allow you to pause campaigns.

Compared to the search engines, the CSEs are truly in the dark ages! I can only conclude that a healthy percent of CSE revenue comes from advertisers who aren't tech-savvy enough to track actual profit from their CSE investment - good ole' "dumb money."

This sort of strategy, if true, is basically a house of cards waiting to collapse. Over time, as Web analytics becomes cheaper, better, and easier to install, more and more "dumb" advertisers will gain the insight necessary to shut down their bad campaigns on the CSEs.

Meanwhile, Google Base listings are showing up within Google results and Checkout is being pushed heavily at GooglePlex. Attention CSEs: if you think you can continue to pull the wool over dumb advertisers, the judgment day is coming. Once Google starts to provide your customers with the true ROI of their investment across all CSEs, you'll have a lot of angry ex-customers. Or perhaps to put it another way, Google will have a lot of your ex-customers as new customers.

Dumb advertisers will eventually learn to be smart. Dumb CSEs can fix their business models today and salvage their relationships with their advertisers, or they continue to rake in some extra bucks today at the expense of tomorrow.

Back when I was a dumb kid, I seem to remember a tale about a grasshopper who lived for today and an ant that prepared for tomorrow. When winter came, the grasshopper had no food and died.

Dumb kids know not to be the grasshopper. Maybe it's time some comparison shopping engines brush up on their Aesop's Fables.

Grading Google's Goods

Man does Google have a lot of products. From mapping the surface of Mars to selling radio ads, Google is everywhere. And with the stock price currently hovering around $515, I guess all of these products that they keep rolling out must driving a lot of revenue, right? Well, some do, but others can only be classified as fun engineering projects that are a long ways away from every generating a cent for the Big G.

I figured it would be fun to grade Google's various products and services on two factors - first, the current revenue they bring in, and second, the potential for revenue in the future. The scores from both of these factors will then be combined to give each product one overall grade.

For the record, I'm not grading on a curve, and due to the shear number of products Google offers, I'm not even going to justify any of my grades! That being said, if you really want to know the explanation for a grade, wait until after class and then write a comment to this blog.

So, without further ado, Blogation's Google Grades (Grades are ordered as followed - current, future, overall):

Jerry Yang?

For a long time, I've used Jerry Yang and David Filo as the models of smart Internet founders. What impressed me so much about these guys is that they had the confidence to push forward with their idea, despite the many naysayers who said it couldn't be done. But more importantly, they also had the smarts to know when to let go of the reins. Once Yahoo started to become a "real" company, they took a backseat and let seasoned business leaders take charge

This is really a pretty amazing transition - many entrepreneurs don't know how to switch from pig-headed visionary to laid-back team player - but Yang and Filo did it and did it well. In many ways, they were the model entrepreneurs that taught Sergei Brin and Larry Page their playbook on going from start-up to mega-corporation.

But now comes the news that Terry Semel is stepping down (or being fired, or both, it doesn't matter) and Jerry Yang is assuming the position of CEO. Additionally, Susan Decker, the former CFO famous for her quote that Yahoo was essentially battling for second place in search, is now President.

I definitely have some mixed feelings on this move. On the one hand, I think it was long past time for Terry Semel to move on. No doubt he did some great things for Yahoo - in particular the acquisition of Overture, HotJobs, Flickr, and Del.icio.us. But he also presided over Yahoo gradual slide from #1 search engine to #1 outsider looking in. And, throughout it all, collected a lot of money - over $200 million in one year alone.

I do think that Yahoo's social media strategy will pay dividends in the long-run, but there's no future if there's no today, and Yahoo had consistently underwhelmed shareholders, search marketers, and employees. It's time for a change.

But Jerry Yang as the new head-honcho? This one makes me a little nervous. No doubt Jerry Yang is an incredibly smart guy, he knows Yahoo better than anyone, and he's a lot more seasoned than he was in the mid-90s when he gave up the reigns to someone else. If nothing else, I'm sure his presence at the top will encourage many smart geeks in the Valley who might have otherwise gone to Google to give Yahoo a second look.

At the same time, however, the guy is 38 years old, he's only worked at one company - ever, and he has been a senior executive at Yahoo during their losing battle to Google over the last six years. If Yahoo needs some new blood to shake the moss off the log, having the founder return as CEO doesn't seem to be the right solution.

I would think that there would be plenty of seasoned candidates - perhaps even senior people at Google - who would love the opportunity to come in and take over Yahoo. After all, the stock is pretty low, the expectations are low, and there is a lot of potential going forward (social media, the numerous big companies that want to partner with anyone but Google, the continued strength of online advertising).

Bringing Jerry Yang back seems a bit like the Politburo in the USSR in the 1970s - once the Premier died, they just elected another equally old, equally stodgy replacement who had an equally ineffective and short career at the helm.

I'm hoping I'm wrong here. More competition in the search space is good for everyone. I'd love to see the re-emergence of Yahoo as a major player and innovator. It seems hard to fathom, however, that Jerry Yang is the man to lead Yahoo to the promised land.

Keeping Google at (e)Bay

There's been a lot of chatter this week about the brewing battle between Google and eBay. Google struck first, holding a "protest party" outside of the eBay live show in Boston. eBay responded by removing all of it's ads from Google. Google backed down, cancelling it's party in Boston.

I've seen this coming for a while now (loyal readers will no doubt recall my "Google vs Ebay" post from about a year ago and my updated post not two weeks ago). In my opinion, Google has long considered eBay - not Yahoo or MSN - as their chief competition. And I have felt that eBay has not taken the Google threat seriously enough - perhaps until now.

What's clear to me, however, is that eBay is not strong enough to battle Google alone. eBay needs Google more than Google needs eBay. The estimated $400 million Google might lose if eBay stops advertising on AdWords is significant, but not debilitating. But if you assume that eBay is spending an average of $.20 per click on Google, that's two billion annual visitors that eBay would be losing. That's a lot of Disneyana and antiquarian book sales.

If eBay really wants to fight Google, they need to enlist some help. My suggestion: talk to Amazon.

Amazon and eBay have something in common that sets them apart from virtually any other company online - both are experts at purchasing "long tail keywords." Type in virtually any product (or non-product, for that matter) on Google and you're almost certain to see eBay and Amazon showing up. Add in eBay's Shopping.com and the chances on any search are close to 100%.

So if Amazon and eBay suddenly stopped all spending on AdWords, this would result in a lot of lost revenue that Google simply couldn't replace. You see, on many keywords, if one advertiser leaves, this doesn't have much of an impact on Google, because a different advertiser is waiting in the wings to assume the departing advertiser's position. But with obscure terms like "first edition leather bound 17th century book", there are few replacements to eBay and Amazon.

Amazon and eBay, however, don't just contribute to Google's coffers via AdWords. Both have huge affiliate programs, and Shopping.com places Google ads on their site via AdSense. eBay also owns major Google spenders like Half.com, StubHub, and Rent.com.

If Amazon and eBay stopped AdWords spending, removed AdSense, and prevented their affiliates from buying ads on Google, this becomes pretty significant for Google. I have no idea how to predict the financial impact, but my guess is that there would be at $1 billion of revenue for Google at play. That kind of lost revenue will have many negative impacts on Google, like a stock price drop and increased difficulty in acquiring companies for stock.

Of course, as noted, this strategy would not be without its impact for eBay and Amazon. You can't replace billions of users overnight. I do believe, however, that there are ways to spend that extra billion dollars productively.

eBay's recently acquisition of StumbleUpon for $75 million was a great move that could have significant competitive advantages against Google. Having a couple hundred million dollars lying around makes it easier to acquire strategic technology and sites with loyal customer bases like StumbleUpon.

With mass media channels like TV and radio hurting these days, eBay or Amazon might be able to lock up a lot of non-search exposure at a discount rate. I've recently seen eSurance.com plastering San Francisco with offline campaigns (buses, billboards, radio, TV). Not sure how this is working for them, but this sort of campaign could help remind folks to go back to eBay or Amazon to see what's new.

Finally, there's always research and development. Google spends a lot of money on their engineering team. An extra billion could buy away Google's talent, or provide more resources for the in-house resources already there.

If any of Google's competitors really want to stop the Google train from rolling over them, they're going to have to join forces. Such a move would be painful for every company involved, but it may end up being the only hope anyone has to level the playing field against Google.

Why Google is No Ordinary Tuk-Tuk

I'm currently on a short holiday in Phuket, Thailand. Walk around Patong Beach in Phuket for a half-hour and you'll be mobbed by vendor after vendor trying to sell you one of three things: tailored suits, Thai massages, and tuk-tuk (little taxi) rides. The local t-shirt sellers have caught on to how annoying this can be, as you can now buy a t-shirt that says "No, I don't want a f*cking suit, massage, or tuk-tuk."

Now I don't really need a suit, but I do admit that the concept of getting a custom-tailored suit for under $100 is pretty attractive to me. Problem is, I have no way of telling all the suit-hawkers apart. They all start with the same come-on ("Hello Boss. Where are you from? How long have you been in Phuket? Please come and have a look at my store"), they all have nice looking suits in the window, and they all charge about the same amount. I could probably spend a week researching the subject, interviewing tailors, asking locals for recommendations, and I doubt I would be any closer to really differentiating any of these tailors.

In short, it's a commodity market, where price is really the only thing that separates the different choices. I suspect, however, that at one point in time, Phuket's tailor (and massage, and tuk-tuk) markets were not so commoditized and saturated. Maybe 20 years ago, some tailor from India decided to give Phuket a try and had amazing success. Every week he had a new crop of Australian and Singaporean tourists who loved the idea of coming back with a nice wardrobe.

And maybe in his euphoria about his business success, he told a few fellow tailors in India and Hong Kong. A few of them came over and were successful too. Then a few more. And so on. Suddenly, there's a tailor on every block. I wonder if that original tailor is still in business anymore.

Back in 2002 - the early days of paid search - a similar thing happened. Overture started really doing well, so a bunch of would-be Overtures entered the market - Google AdWords, Sprinks, Ah-Ha, BlowSearch, 7Search, Kanoodle, FindWhat, ePilot, Mamma.com, Infospace, GenieKnows, and many more tried to make some bank on the PPC gold rush.

For a while, a lot of these companies did quite well. As this was a pretty new concept, few advertisers were savvy enough to differentiate the quality traffic from the crappy traffic. It seemed pretty cool to get 10,000 clicks from Kanoodle for a few cents a click - surely that was a good marketing buy.

But unlike the tailors and tut-tut drivers of Phuket, the paid search market is not a black box. Over time, it became clear to advertisers that some search engines had great traffic (Google, Overture) and most had horrible traffic. Slowly but surely, the Overture-wannabes packed up and went home.

Google, of course, has remained. Why - because it has the quality traffic (the GlenGarry leads!). Having quality traffic is like having a tailor store or tuk-tuk stand in front of the biggest, fanciest hotel, with no competition for miles. You just sit back and watch the money come in.

Interestingly, it took Google a while to realize that they should actually promote the quality of their traffic. Google use to provide advertisers with little more information than the number of clicks and impressions they'd received. From that information, it's hard to tell Google apart from ePilot.

In the last few years, however, Google has lead the charge toward PPC transparency. They make it easy to bundle Google Analytics with your paid search campaign, they offer conversion tracking, negative keywords, site exclusion, and most recently "search query" and "placement" results (so you can block bad AdSense publishers and bad broad-match keyword extensions).

This is not Google's attempt at advertiser altruism - it's a smart, calculated business move. If you have the best traffic, you should flaunt it. And that's what Google is doing.

Somewhere on Phuket Island, there are some tuk-tuk drivers who are truly amazing. They could probably give me an Insider's tour of Phuket Island that I would never forget. If I could find them, I'd pay double or triple the going rate. Unlike measuring online advertising quality, it's next to impossible to add transparency to the tuk-tuk market.

Why the Internet Will Make Roger Ebert Obsolete

Anyone over 30 no doubt remembers watching "Siskel and Ebert at the Movies" growing up. A "two thumbs up" review from the two movie reviewers could easily drive millions of dollars at the box office for a lucky movie.

And despite Siskel's death, Ebert still continues the show, now with Richard Roeper as his cohort. There's no doubt, however, that the importance of a "two thumbs up" rating these days has diminished, and it's not because of Siskel's death.

Indeed, the importance of all types of reviewers, be it movie reviews, restaurant critics, or even consumer reports, seems to be growing less and less by the day. No doubt the Internet is a major driver of this trend.

To date, the Internet has largely impacted reviewers by simply giving consumers access to more choices. You no longer need to wait until Sunday night to watch Ebert review a movie - you can instead go on to RottenTomatoes.com, or a movie blog, or a chat board, and get dozens of opinions about the latest blockbuster.

The same is true for getting information about autos, electronics, books, hotels, and so forth - a quick search on Google will give you hundreds of opinions about any area you want.

The downside of the explosion of information is that it becomes difficult to wade through the data and find the stuff that is actually relevant to you. Unfiltered information is useless and actually makes you want to go back to an expert like Ebert that you trust.

Most Internet review sites today, however, have solved this problem, usually by asking reviewers to give a star-rating (sometimes on multiple factors) to whatever they are analyzing. You can then see an overall summary of the collective wisdom without having to read 500 reviews.

But the best is clearly yet to come. As any loyal reader of this blog knows, I love collaborative filtering - the Amazon.com idea of "people who bought this item also bought this other item." So far, the online review sites have not utilized this principle. For example, if you go to TripAdvisor.com, you can always find dozens of reviews about a hotel, but it is difficult to know whether a particular reviewer shares your criteria for a good hotel.

With collaborative filtering, TripAdvisor could start to match you up with people who have similar taste in hotels. So if I really liked the Motel6 in San Antonio but hated the Ritz in Half Moon Bay, and you also had the exact same opinion on these hotels, the next time I was thinking about going to Dallas, I could review your picks for Dallas and likely find a hotel that really works for me.

Collaborative filtering actually works on a much greater scale: if there are 50,000 people reviewing hotels across the world, the odds are pretty great that whatever city I am visiting that someone with my particular taste will have already reviewed a hotel in that city.

There is a new web site called Flickster.com that is doing this with movies. I'm assuming that it will work along this model - the more reviews I submit to the site, the more it understands my preferences and matches me with other reviewers. Over time, I should be able to type in any movie and get a pretty good idea of whether I will like it.

This is a lot more accurate than listening to Roger Ebert because it is a lot more personal. I'm sure that if I sat down with Roger and told him about movies that I liked and disliked, he could come up with some good suggestions (for the record, I have actually talked to Roger Ebert several times, as I used to review movies when I was in college in Chicago). But even personal recommendations from Roger would not be as powerful as the collective knowledge of thousands of moviegoers.

There's no doubt that this model will soon be applied to movies, restaurants, hotels, and perhaps even doctors, lawyers and other service providers. But I actually think that the most interesting application of collaborative filtering will come with respect to eTail - online shopping.

Right now, every comparison shopping engine uses a star-review system to enable customers to provide feedback on their shopping experience. eBay and Amazon have a slightly less accurate system, basically asking the customer if the experience was positive, negative, or neutral. And Google's "Quality Score" measures the frequency that users click on a Google ad, go to a Web site, and immediately return back to Google (click the back button), a measure of the lack of relevancy for a particular site.

All of these systems, however, are still the 'old school' wide swath of information. From general information, you get a general feeling for whether a merchant is good or bad, but you don't really know if that merchant is right for you in particular.

For example, let's say you don't care whether the merchant has 24 hour customer service, but it is vital that the merchant offers Saturday delivery. You can't easily glean this information from 500 user reviews.

But with collaborative filtering, this becomes very possible. As you review stores, the collaborative filtering system starts to understand what is important to you. It can then match you with users who have reviewed other stores. After a while, the system's accuracy cannot be doubted. You can do a search for "digital camera" and the system can not only recommend cameras that you are likely a good fit for you, but also recommend merchants that will provide the best customer experience for your needs.

Most consumers would gladly pay a few dollars more for a product if they knew that they were going to have an awesome shopping experience. I think that that is actually the promise of comparison shopping, a promised that is definitely not fulfilled by a vague star-rating.

The end result of such a system would be tremendously valuable to consumers. After all, a company that consistently provided horrible service simply would never be matched with new consumers - there would be no way to hide from your business quality.

It would also likely spell the end of an organization like Consumer Reports, which in most ways is no different than Roger Ebert.

The Internet is making today's experts obsolete and creating new experts who's status is determined by statistics, not the mass media. While this will put people like Roger Ebert out of a job, the end result is a great victory for consumers - product and business transparency that will make shopping easier and more personal and hold businesses accountable for bad service or products.

When The Average Man on the Street Isn't

A quick post on a strange phenomenon I've noticed recently in the Wall Street Journal. In the past month, I've seen two of my friends from the SEM world quoted in the paper - Ellen Siminoff, CEO of Efficient Frontier, and Matt Schnuck, CEO of Trouve Media.

Now both Ellen and Matt are clearly experts on SEM - Ellen being an early Yahoo exec and the CEO of the biggest bid management company on the planet, and Matt being an early Quinstreet employee and the CEO of a very successful online lead generation company. So you might think that there is nothing unusual about either of them getting quoted as experts in a major media publication.

The strange thing here, however, is that both are being quoted as the "average man", in stories without any focus on paid search. Ellen was quoted a few weeks ago as a user of the new travel Web site, Yapta.com (which, by the way, does sound pretty cool). Matt, on the other hand, appeared yesterday as a "wedding attendee" of a guy who uploaded his wedding video online.

Granted, both of these stories have something to do with the Internet, but in neither case is it revealed that Ellen and Matt are actually Internet experts. It would be like doing a story about the NBA and interviewing "sports fans" Michael Jordan and Larry Bird.

For the record, I don't really have an angle on this post - I am not criticising the WSJ for quoting search experts in non-search stories (and for that matter, if they want to quote me on any random issue, I have an opinion on everything . . .). I suspect that a writer at the Journal use to write a lot about search and made some connects in the industry as a result.

The next time I read their "money and investing" section and see a quote from "small business owner" "Donald Trump", I may be a little more skeptical.
