Welcome to WebmasterWorld Guest from 18.104.22.168
However, it could have been another site you were looking at - or another advertising program ;) Google is hardly the only company distributing text ads on sites, or selling text links, or offering webmasters the ability to show CPC ads on their site.
Heres a thread [webmasterworld.com...]
The ads just look a little ugly on our site (see profile, go to directory and Africa -> Algeria -> Other Localities for initial test). I would much prefer it if I could add some degree of customisation.
