Hi,

i was wondering as to how Target marketing ads are placed on sciforums site, since there is a post on vegan diet and i saw the add of the same...

Yes i was wondering why that was under my post on my thread as well. Very strange

google scans the first post on each page for key words then displays an ad which it finds to be relevant. if it cant find anything relvant then it crosses your IP with popular google searches. that is why i have an ad for "healthy recipes from NZ"
