Google is self-editing (on the free side). You can apply to be an editor. These so- called "editors" evidently set the priority of sites that show up in a search.
I manage online bidding for a company, and try as we will, we can't figure out how Google figures our bill. It's definitely not straightforward like Yahoo/Overture pricing for ads. Of course, Google has agreed to settle a huge class action lawsuit, acknowledging click fraud has been going on.
But Google won't disclose how they "calculate" your charges or your placment among the "free listings."
Personally, I think people are starting to use other search engines because I'm noticing "impressions" overall, are significantly lower than they were this time last year.
Also, Amazon has just decided to go with MSN powered searches instead of Google powered searches. Google may have peaked...time will tell.
How does one apply to be an editor?
Does anyone know of another search engine that has the cache function that Google has? That's basically the only reason I use them.
Also, I HATE how the word "Google it" has become a phrase in our culture. If anyone has an alternative phrase, please let me know. The legitimate alternative just doesn't flow well for me: "Hey, why don't you 'general search engine' it?"
