Favorite backlink tools

,

SEOMoz Open Site Explorer
ahrefs Site Explorer
Majestic site Explorer

All three of these tools will give you a really detailed, clear look at your backlinks and even anchor text distribution. The issue is you may also get different data from all three. They each have their own indexes and may report different backlink numbers. So while only using one tool may let a few links fall between the cracks, right now, using one or more of these tools may be your best shot at finding the backlinks you need to get rid of.
