BritishTwinks - don't bid on terms like "gay sex" as they cost more and are harder to make sales with. also you have to tweak the ad. google is a challenge because you can't use "dirty" words, but some words do a lot better than others.

another thing about using google with sponsors is that if someone else is promoting the same sponsor you are for the same terms, expect to see a lot less sales - sometimes almost none.
