| I agree with your analysis that Google basically sells "this person has just looked for this good or service, now who wants to respond?". But you seem to be ignoring the large, persistent information advantage that Google has over Bing. Consider 3 scenarios: 1. Person A just searched for "What's the best sports car?". 2. Person B just searched for "What's the best sports car?". He's a 45-year old man who works for an insurance company in New York. He has a wife and three kids, but he recently started seeing a 28-year-old psychology grad student in Chicago twice a month. Two years ago he bought a $6,000 watch for his wife's birthday. 3. Person C just searched for "What's the best sports car?". He's a 23-year old man who lives with his parents and does not have a wife or girlfriend. He works for Walmart and has just been promoted to manager. Nine months ago his friend bought a Subaru WRX. Now consider what types of advertisers will bid for each search. And perhaps more importantly, what types of ads and landing pages will be offered for each search. Clearly, having detailed personal information is a significant advantage when deciding which ads to show to a user. Google has that advantage and doesn't look like giving it up any time soon. However, I can think of two pieces of evidence against this argument: (1) Bing was able to outbid Google to be the default search engine on Firefox; (2) Outbrain and Taboola regularly outbid Google AdSense to advertise on Time, Forbes, Bloomberg, etc. In both of these cases I would have expected Google to prevail, so perhaps Google's personal-information advantage is not as strong as I think. Or perhaps Google isn't taking full advantage it. |
My point is that in my opinion you are over valuing Google's user information advantage. Most purchasing and buying habit information is collected using web page based analytics to an advertiser rather than coming from Google directly.
When Blekko was operating at a consumer search engine we got a great inside look at what tools advertisers have at their disposal to "qualify" their ad bids. If you send the query's source IP to the ad network when you request an ad they match that up with all sorts of cookies and beacons that have fired off that IP address. None of that comes from Google, it comes from all the trackers that are running all over the Internet.
