Why do people click Google ads?

In all the time I’ve used Google’s search and other products, I can’t recall ever clicking on an ad because I found the ad appealing or useful. Most people I know don’t click on too many ads either, which just doesn’t add up. Given that Google is a multi-billion dollar behemoth whose revenue is almost entirely comprised of fees for ad-clicks, someone’s got to be clicking those ads, they just don’t happen to be people I know.

Google Blogoscoped has an interesting post about how Google’s text ads aren’t easily distinguishable from search results. It seems Google commissioned a market study by Eye Square and TNS Infratest to assess the efficiency of sponsored links on result pages.

Following the completion of that study, Google circulated a presentation to their advertisers with one slide depicting the results of an eye tracking study, showing what users eyes focus on in results during the first 5 seconds; one of the major focus areas is the yellow box displaying AdWords at the top. Another slide in the same presentation tells advertisers how easily those AdWords are confused with organic search results.

Google’s presentation even goes on to quote parts of an interview with a test user:

INT [interviewer]: “Why do the results on top have a yellow background, did you notice?”

TP [tester]: “I didn’t notice this.”

INT: “What does it mean?”

TP: “It definitely means they’re the most relevant.”

That goes a long way towards explaining who’s clicking the ads–a lot of novice and intermediate Internet users that don’t know the difference between ads and search results.

Hmm, wonder where on Google’s “evil scale” that little trick lies…
