Hey,I was wondering if I will have issues placing more ads on my site. Usually google sees that you are trying to place more then 3 ads and makes one of them be blank or it wont appear on the page. Well today I have used more then 3 ads on one particular site. It is really strange that I was able to use text unit ads in same page for 3 times,while leader board and block ad was displayed. Everything was in the same page. So is it legal to use same adsense code couple times on same post ?
