I have 32,530 (no dups) tier 2 links that I need to do something with. I have GSA SER but I run it on a Virtual Box on my home computer. It is not going to handle backlinking this amount of links. I would imagine there would be a huge bandwidth usage concern trying to post to 32k+ sites (I don't think GSA SER uses sockets). I would imagine it would take a lot of time (my VB only has 2 AMD 6100 processors to run it). What is the best way to get some backlinks to this big load of URLs.
