Improve Infolinks Revenue Using Single Dotted Line

Infolinks has two type onf in-text-link ad, double and single dotted line.  After tried using two types of Infolinks In Text Ads, double line and single dotted line, I choose to use single dotted line.  Here is the reason.
Infolinks recommend double line, but in facts, based on my experience, performance or CTR of single dotted line is better than double line. I think that this is caused by appearance of single dotted line is more similar as hyperlink or regular link to a page or website than in text ads, and seems as the part of whole content. Try your Infolinks experience by yourself, by join using this link, and start to get revenue.
