How come SEOMOZ isn't showing the same inbound links that Webmaster Tools does?

Webmaster Tools shows inbound links that don't show up in SEOMOZ. What is that?

Hi,

Google's crawler (GoogleBot) has a separate larger database, crawl rate ect... than Open Site Explorer (RogerBot)

I also think in general the OSE index is updated once a month ( i think they are working on making it more often and expanding the crawl database)

Google's index is updated more often than that.

In short, OSE is just a different "snapshot" of the net then Google's much larger database of the web

Hope this helps

OSE only about 25% of the size Googles index is
