Hello,
I am using adsense for last four years, recenlty I heard that if you use just one ads units on single page instead of using three or two, it will increase your earing? if yes , can anybody tell me the logical reasons about it?

Reduces ad blindness on the part of the users, more competition for less space on the part of the ads can lead to higher pay ads, plus in many cases it just *looks* better. I posted recently in another item that I dramatically increased earnings per click and eCPM by taking it down to just a single link unit.

I did not think coz GOOGLE ADSENSE allow ur self more than 3 LINK UNITS and allow yew to put 3 ad units so u can paste in this LIMIT. if u break this limit or got out from this limit than may be Code doent work or CLICK CTR low etc problem, If you are using adsense from last 4 years u know about it easily.
