| Let's go back to step one: Google's revenue is rising by what % a year? Google's user base or searches are increasing by what % a year? Is there a difference and what makes that difference? Google's recent stock growth and revenue also match Google's highly publicizes Panda and Penguin updates. Or supposedly fighting "spam" but in reality also ruined a lot of small businesses. My educated guess is that Google is sending a lot less "free clicks" to other sites. Cost per click can be brought down by a supply gut or a poor ROI for the advertiser. >> In any case, the considerably more obvious and likely explanation is the one I think most people have tended to assume: google disambiguates terms automatically because it's what works in the 90% case. In any case, the considerably more obvious and likely explanation is the one I think most people have tended to assume: Google makes sure that any algorithm changes (at least) don't hurt their Adwords business. That's their bread, butter and dessert. |
