Anyone tested Open Site Explorer backlink numbers ?

Hi,

I am new here and I have noticed that open site explorer reports about half of the links on  my page.

I am really interested in knowing your perspective on this.

cheers,

OSE is based upon the Linkscape crawl of the web. Linkscape is designed to crawl the top 25% of web pages based on their importance (i.e. links). The crawl process takes 2-3 weeks, and then it takes 1-2 weeks to process the data. About once per month the Linkscape data is updated.

The first reason your links may not appear is it can take up to two crawls for a link to be seen. Depending on when the link was added, it can take 2 months to be visible in OSE. The Linkscape update schedule can be seen here: http://apiwiki.seomoz.org/w/page/25141119/Linkscape%20Schedule

The other reason a link would not be seen is if it is on a page with low PA. A page with low PA wont pass any real link value so it is not included in the link profile.
