Only after compiling this mega list did I realize how many tools I use on daily/weekly basis just for link building. I have mainly listed those tools which I use often and which are free to use. I keep adding/removing tools as I find better alternatives.
If you think a tool is worth listing then please suggest it. Please note: I do not accept paid inclusions.
