I looked through the TOS a minute ago to check and couldn't find out whether there is a limit to the number of ads you can have on your page.Is there, if so how many?
Yes there is a limit on the number of ads. Blechiv is right and extra ads won't show anymore once you exceeded the limit of number of ads.
Their is limit but you want something more than you can go for affiliates products to in Google . You can add more than 5+ affiliates on your sites . Try niche related links to promote they will work better .
Yes definitely it is 3 ad units, 3 link units and 1 search boxes! Extra ads than this won't appear in your website. If you put more than this means
