I recently saw a video from a guy teaching a technique with XR, where he loaded a bunch of URL's from GSA and ran a link pattern analysis, so he would end with /register/user /register.php and so.. and then ran an inurl search with the most common paterns to find new platforms. I think an inbuilt version of that would be great.
Now, something I'm doing by hand and I think it would be a killer feature:
Since most people is doing multi-tier campaigns, it's very common that an external link in a forum profile where we posted with GSA leads to another platform where there's a contextual/better quality link/Tier1 link. So the mechanic would be:
Doing it with SB has lead me to some good results, but It's not as automated as it could be doing it right from GSA.
Hope you like my ideas
