I have always been able to get many search queries using the Google Search but I haven't had a single click? Does this mean people realize its a normal Google Search and decide not to use it? I also have custom results showing up on my site and the option to search my site using the Google Search. Anyway, any suggestions will help and heres my site if you would like to look for yourself. www. evilpsp.com
Adsense Search? You only get paid if they click on the ads within the results--not on general results. P.S: Nice site!
This could do with the keywords your visitors are searching for since some keywords may not display any adverts. I have a lot of search queries on my site but clicks are very rare so its normal.
I get this a lot as well on my site, which has Google Search enabled. The CTR tends to be fairly low, so I view AdSense for Search as just icing on the cake. It makes me a few extra dollars per month, but certainly can't match my earnings from bread-and-butter AdSense for Content advertising.
