I'm sure a version of this question has already been asked, but I couldn't find it when I did a search. When I try to find out the number of links pointing to my site, I seem to always get a different number depending on which program I use. Be it Google, Traffic Travis, SEO Moz Site Explorer, etc, the number of links that they report pointing to my site are all different. So I have been keeping track of the number of links across multiple programs. But now with more site to keep track of, its becoming too much work. So I want to just pick one program to track the number of links going to my site, and to the competition. Which program do you guys use and find to be the most accurate?
