Look at this site http://textssender.com/ I can see about 6 adsense's, how come? I thought if we add more than 3 then the rest will not show up ?!
Oh i see, so 3 adsesnes with 3 link-ads in a page at the same is okay with google ... hmmm didn't know that , thank you.
You are allowed to put 3 link blocks and also 3 text blocks on the same page. In total we have 6 adesnse ads on the same page lol.
It is truth. And you can get banned for it. quoted from: https://www.google.com/adsense/support/bin/answer.py?hl=en&answer=48182 BTW if they want to use your traffic they will wait until you have sold $100 in clicks and then tell you that you are banned.
But I know that there's some code there wherein when you post more than three text ads or link ads, additional ads won't load up. This is the prevent publishers from posting too many ads.
too much ad doesn't mean many $$ in single page. Place in good location with good content is much important.
More ads often mean less revenue. The first ad has the highest-paying links, that's where you want people clicking. Other ad blocks are more likely to have those $0.01 MFA arbitrageurs.
