I am telling you a long story in short that, there is website out there which ranks in google for many keyword in top ranking, i go behind it, user my premium moz, ahrefs, seoprofiler accounts to see what's going behind it. When i see the result i was amazed, here what i see More then 40k total backlinks counts and more interesting thing is, all of these links are from profile, comment, directory etc. Just for testing purpose i go open one link which is actually a form profile link, i see that in visitor and bio message there is link back to original site. (Now i am thinking that if all these links are from profile, comment, directory etc) how they do that. ?? I go deeply and just copy the the forum profile link that i open before and insert it into the opensiteexplorer, ahrefs and other tools that i have. Now the amazing thing came here, i shocked that a profile link has more then 20k links ... I open more then 200 backlinks from my competitive site, and i see that every backlink has more then 20k backlinks, (Its something like giving backlinks to backlinks of website). I am just now confused. how did they make these links. ? (I am sure they user software to do that.) If we count then in total they made more then 5m links (giving backlinks to backlinks also counted) .. Which tool they use to do that .. ? Any faster poster link this ..? (I also see this site when it lunched in a total of 3 months they created these huge link structure ..) Now my question is that which tool they use to do that, i also see the work of scrapebox, its not very fast poster and its comments posting rate also below then 40, which tool they use ..? Any idea any point ....?
