I just wanna ask that does adsense pay better if placed on top than at bottom. Just need some experienced webmasters to guide me here.
Just one ad block? No, position doesn't matter. Two ad blocks? Then the one that comes first (in the code, not necessarily on the page) is supposed to have the best return.
Adsense doesn't "pay more" based on where your ads are positioned, although your ad's position is important for obvious reasons, because your visitors may be more inclined to click on an ad that has been positioned well as opposed to thoughtless positioning of adsense ads.... Just my two cents....
Yes and no. If you only have one ad block, it doesn't matter. If you have two, they don't "pay more for one" BUT they do put the better performing ads in the first ad block in the code....supposedly.
