What is your favorite Backlink Checker tool?

Majestic SEO is pretty decent as well.

AHrefs is the most powerful. The first paid option is enough if you just have a couple of sites or are a micro site jockey.
So good it found someone had been trying a negative SEO attack on one of my sites which I just about managed to catch in time and dilute.

Vital to have good BL checkers now trhat Google have declared open season for short term negative SEO (still not convinced it has any real affect long term - but short term is bad enough)

Ahrefs is the besy IMO.

What is the purpose for backlink tool, I am new to CB and want to earn 50$ per day. I start with writing articles and created blogs. I need some free software to promote my blogs in forum

Thanks in Advance
