To calculate **rating for domains** we assess links between them.

If *Domain A* has at least one page with a dofollow link to a page on *Domain B* - we remember the fact that *Domain B* has a link from *Domain A*.

There are a few simple rules to consider while calculating:

1) the higher rating a domain has, the more of this rating is transferred to linked domains (as defined above);

2) all linked domains receive equal amount of rating from the source domain, ie. low-rated domain with small number of linked domains can influence your DR more than super-popular domain (which links to million domains).

Repeating the calculation process for dozens of times, we get a rating for each domain. And the final Domain Rating value is obtained by scaling computed absolute value into range 0..100.
