QuidProQuo

QuidProQuo automatically scans through your site to locate your link partners. It then spiders through your link partners sites to verify reciprocal links back to you.

It will find the link cheaters (those to whom you are linking but are not returning the favor). With multi-threading it allows you to speed up the process by spidering multiple sites at the same time (the lite version has a maximum of 2 threads). The software checks links through the Yahoo search engine first to find the reciprocal links to accelerate the process. You can save your results to excel/csv format. In addition, the full version allows you to speed up the process further by spidering upto 16 sites simultaneously.
