Thanks for the awesome new backlink checking resources... I added reputation to those who added new tools I haven't heard of. The key with any backlink tool is to compare it against itself. There are tons of different backlink checkers all with their own strengths and weaknesses, so to compare them against each other isn't helpful for finding your backlinks. Just compare whatever tool you're using with itself every few days or every week,and you can see the growth of your link building campaigns.
