0 Where should I put my ads, what color should they be, and how many should I put up?

This is a question up for a lot of debate so i’ll give you my take on it. Every site is different, some work well with one ad in the sidebar, some with an ad under the post title and after the content. Some do well with a few text based ads and some better with a mixture of everything.
I generally start off a site with the same layout. That is one ad, at the top of the post aligned left. I normally size this ad 336×250 or 300×250
