They will explain how to use the software, where this section will go into a bit of detail about the results you get back.
The most important datapoints you get back from the link analysis are the link scrores, which are determined as follows:
None - this means that no links were found, either because the URL was not processed (see below) or simply because we could not find any links on that page. It typically means that the link is no longer live.
Not processed - in the Link Analysis 'Settings' tab you are able to set the maximum number of URLs per domain (to a maximum of 10). If you have set this, and you have a domain with 500 different URLs linking to you, it will only check 10 as specified and not the other 490. Everything else will be classified as 'Not processed' and will appear on this tab. In real terms, if you have any more than 10 links from any one domain and there is no good reason for it, you should be treating this as a spammy signal (e.g. link in the footer).
Ignore – don’t pass PageRank or are ‘safe’
Low – shows signs of being a low quality link
Optimized – anchor text optimized for rankings
Suspect – needs to be manually reviewed, but likely to be deemed unnatural once checked
Unnatural – clearly demonstrating manipulative practices, should be removed or disavowed
Review - All followed links that don’t match any of the above options (i.e. the default is set to ‘Review’)
