If you look at adsense, sometimes the link text is bold and sometimes its normal font, but with Chitika its always notrmal font. I feel bold lettering attracts more attention to the ads and have higher CTR. Also, I cannot get Chitika inline text ads to work. When I preview it in the control panel, none of my text gets highlighted. Also, have they dropped RPU (related Products Unit) from their list of types ads served?
