I discovered by accident that the Adwords algorithm can weigh the name of the directory you put your file in very heavily.

The home page of my site at

http://wordsmatter.softville.com

has keywords and links relating to language and writing and most of the ads Adwords picks are appropriate.

When I look at the copy of the page on my own machine, however, it's in a directory called /localhost/phptest.

When I view the local copy, Adwords fills the screen with ads for php tip sites, php cheat sheets, and MySQL tools, even though there's nothing on the page or in the meta tags that would trigger this behavior.

Unless I'm misunderstanding what's happening, it means that Adwords users need to think long and hard about the directory structure of their sites since the Adwords engine apparently cares more about the directory name and domain name than it does about anything on the page.
