How is OpenSiteExplorer of Moz compared to other link analysis tools?
I once tried it. What can I say compared to other tools its a bit slow. Links gets found out pretty late in it. Although, it was few years from now so I can't tell really how is it now.
We strongly recommend our clients to not to use it.
I don't know why people are so obsessed with this tool anyway. It don't even find the backlinks correctly.
