Well, we average about 2 percent CPR but we don't have any search terms with top ranking, nor do we want it. 30 searches a month seems really low, so you might have a specific term, where you might get better rate with you having a top listing. Must be nice to get a top result with a $0.10CPC bid. ;)
Kosar it also highly depends on how many other competitors you have bidding against you. Odds are if you are paying 10 cents per click, you are one of the only people bidding on that keyword. In which case there will be less ads displayed and you CTR can be drastically higher than just a few percent.
