That's pretty decent. Depending upon the sections of my site and how many ads I show per page, I end up being in the 3% range. The link directory is crazy at 8%, but I think that's because it somehow sorta mimics the look of AdWords in the right sidebar on the google search results.
Yes. But keep in mind the link directory doesn't get a large number of impressions. 1 click in 10 views is 10% after all ... Not that it's that few, but compared to the rest of DaniWeb, it might as well be.
I dont really understand it though, i've only just started using it, it started at around 1% then at the weekend I got 11% and 16.5% which was very rewarding
I would be very careful if I was you. For a CTR to jump from 1% to 16.5% in a matter of a few days is a BIG red flag. Google is known to ban people from adsense on suspicions of click fraud.
If you see a big jump in CTR, you should investigate it.
1% is about what I had when I used adsense. Of course, my first site had a huge spike (someone clicking links to try and get me more money?) which caused Google to shut it down. It took me a couple of weeks to convince them that I had nothing to do with it and get my account unfrozen.
From my experience, CTR for adsense words depends on categories and there could be vast differences between the keywords within that same categories. Usually 1-3%. In some long tail categories, I have seen CTR of 0.1%!
I personally don't think adsense is the way to go. I would rather run a private ad system and have my own algorithims and ways of deciding what ads show up where than using Google Adsense. I've seen regular users go crazy with sites that use adsense... and understandably so... some webmasters make it impossible to tell the difference between a link on their site and an adsense link... and then the popups oy!
