PageRank (PR) had always been the go-to metric to decide the power of a domain. PR was discontinued back in 2013, but the data is still available and put to use. However, since the data is no longer being updated, PageRank is no longer valuable to determining the authority of the domain. Over the years, many new metrics were introduced by services such as Moz, Majestic, Ahrefs, SEMRush, etc. These are now the new metrics for filtering out the good from the bad. GSA SER in particular, had always depended upon PR to sort the target domains for backlinking. To get more accurate numbers, GSA PR Emulator was introduced to work alongside GSA SER. The tool maps PR to either Yandex, Alexa, or SEMRush metrics. Domains/pages are sent to GSA PR Emulator from GSA SER and then returned back with a mapped PR.
A couple months back, I went over using an RSS feed for project URLs in GSA SER. This is useful when you want to do deep linking to a site that is constantly being updated with new posts. GSA SER will parse the RSS feed and choose a random post/link from the feed. Recently, I wanted to use multiple RSS feeds for a SER project. I had multiple Tumblr blogs that I wanted to build backlinks to. It was a bit tricky, so I decided to write this brief tutorial to help.
