Hey guys, If you are a user of GSA Search Engine Ranker, then you know that without quality proxies, you won't get much of anything out of the software. I have been using SER for a long, long time and have tried several proxy providers, but throughout my tests, I have found 3 to work great with this tool. So, I decided to line them up side-by-side and test their capabilities. In the end, I compare their VpM, number of contextual backlinks built, unique domains, a breakdown of the backlinks by engines, and a few other metrics. Hope you like it. http://www.inetsolutions.org/case-study-comparing-the-top-3-gsa-ser-proxy-providers/ Regards!
