I added the ads to the top of the post with a red tittle with the 336 square and the earnings went up, not a dramatic change but it gave my sites a really good improvement. Having a red color on the tittle is not a violation, is it? I read the rules and couldn't find anything for that. Anyways what works for you guys
Always , if you place your ads on the top of the page , it will catche to the visitors. You can earn more money for top ads. You can also try with link ads on the top.
In my case, I rotate ad color schemes to avoid ad blindness. I also experiment with bright text on dark background with good results.
always good to put ads at the top of page like suggest i mean when you go on to a site where do you look the most i always look at the top i rarely look at the bottom. Best thing to do on earnings is trial and error.
If your article headlines are black and your hyperlinks are blue, then your Google AdSense should be set up the same way, with black headlines and blue links. Many studies have shown that the best place for an AdSense ad block is right between your headline and the text of your article.
