I am very curious on what is the best adsense placement for all of you? big banner, half banner, large rectangle, ad links, etc.
I agree with MeZlex...I don't run adsense myself, but standard affiliate programs links that blend well with a site do appear to do well. You can make them stand out a bit but so many simply avoid looking at items that look to much like an ad, especially images IMO
I can't explain my best placement in one word. For me, I need good content, placement, colors....... This poll isn' too accurated.
Davilac is right on. Every site is different. Obviously, ads near the top (top left) will get more clicks as that's where people look. How many viewers will scroll to the bottom and click on an ad there? You just have to decide for yourself whether revenue or look & feel of your project is more important.
Square ad units blended in with my content work best. I use the 336x280 blocks inserted into a 340 wide table (cellpadding = 2), right aligned. These work better than skyscraper and any horizontal format for me. Everything works better than link units (great CTR, but low revenue per click).
