Why Aren't All My Backlinks Appearing in Open Site Explorer?

Cross-referenced on Google Webmaster Tools and it looks like MOZ isn't pulling all my links. Any reason why? Thanks in advance!

Hi there.

It's quite simple - Moz crawling resources are way smaller than Google's. So, instead of crawling every single possible page and link, MOZ pays attention to top pages on your (and others) domains, as well as they look at domains, which are more correlated to rankings, rather than every single possible one.

Moz doesn't crawl everything, nor do they crawl as often as Google.You're getting a subset.

You should never take OSE as the sole source of your links. Cross reference with other tools (WMT, Ahrefs, etc). OSE is designed to give you a subsection but to make sure that subsection is as data-rich as possible (note that OSE ranks your links as well).
