Heya there =) I just made a Poll for one specific Ad , the 336 x 280 Ad. In this poll i want to know where in ur Blogposts uve insert this ad, at the top ( below Title ) , Middle ( in the text ) or at the Bottom ( after the text ) and which kind of results uve made on that specific placement.
Best place is top left hand corner in the body. You can have about two lines and then place the ad left justified. Then wrap the ad with content. This way the ads look like part of the content.
Yes! Below title is the best. On 70% my web sites this is the best CTR add. text and url in add should be in black color (like text on page) and title of add I put red on something similar.
