The way I like to work with Open Site Explorer is to group the link data (after downloading it in a spreadsheet) by site types.
This is done partially by searching from certain strings within the URLs, page titles or even anchor text, and partially by manual review.A typical way of grouping the links would be into:
- directories
- partner sites
- forums
- article directories
- dofollow blog comments
- etc.
I also like to sort the links by country, especially if I'm trying doing SEO for a local version of Google.
I don't really look at how much juice a page passes, I haven't found the MozRank to be too useful when sorting out through the link data.
Cheers
