The Page Links Overview Report
The page links overview report is similar to other links reports, but in summary form. This allows you to quickly and easy get an idea of site and link structure.

Source URL
Is the URL that links are originating from or to.
Title
The title of the page.
Inlinks / Inlinks Unique
This is the number of links found in the site crawl that point to this page. Another page may link to this page several times (this is often the case if it is in a main menu and then, for example, mentioned in the body). Inlinks counts all these links. Unique Inlinks will only count a maximum of one from each page.
Outlinks / Outlinks Unique
Works exactly the same as Inlinks / Inlinks Unique but for links from the page to other pages.
Tips
You can sort columns by clicking on the header. If you sort Inlinks Unique to be descending then you get a good ranked overview of how important pages are considered internally on the site. Similarly you could sort by Outlinks to find pages that are perhaps linking to too much.
