What is your Average CTR? In your opinion what is the right CTR for any site/blog?

I get 0,5 to 0,7...

The more visitors AND repeat visitors, the lower the ctr.
Everybody who comes back every day will remember where your ads are and only click seldomly.
When my site was small I got ctrs up to 4 or 5 percent.
As I improved quality, my ctr went down and to 0.5
( the problem in my case is that when I improve quality, my content - which is animations - distracts more and more from the ads. - the text content stays the same )

But I get a lot more visits and a bit more $ .... So its ok

From my experiance: Sites with less than 10k visits a day get high ctrs 3 to 5
And for sites with up to 100k per day, u often get 1 % or even much less.
And 500k per day..... hmmmmmmmmmmm --- Never experienced the pleasure....

But of course this also depends on the niche.

 

It is quite understandable that the more traffic you get the less ctr you get I guess, at least thats what it seems from the trend here. 5% Ctr for a high traffic site is quite absurd don't you think? Talking in thousands everyday here of course.
