It is well known that Adsense allows 3 ad blocks per page, but I read it is not convenient to put all 3 in a single page for the click value. How many blocks do you guys-gals use per landing page? What other systems are good to use (like Chitika) and how many per l.page? Thanks
I would say...it all dependes on your niche... I tested one of my sites with just one ad block and there was a huge fall in adsense revenue...but yes I have heard that it do works well for some people.
The only way to really find out is to test it for yourself on your website, personally i'd go with 3, but you never know till you try.
Trial and Error. On one of my sites, I can put 3 ads and get money and on another one, only 1 will earn money. It is based on: How your site is designed Niche
Here's another for the ol' trial and error. I've had success with it sometimes and other times it's best just to have one single unit well placed.
In some cases there aren't even enough advertisers for so many blocks. In others, the more you have, and the more opportunities to catch the attention and the click of a visitor. So I agree, the niche has a lot to do with it. But also the webpage layout, sometimes it would be awkward to fit all 3, sometimes it's fine and even needed. There are other factors, but these are the most important I can think of right now.
as stated, it all lands on "see if it works" in cases like this imo: it depends on the layout of your website wrather u should use 1, 2, or 3
