This backlink checker from Majestic gives you a really fast way to see the strength of any page based on its backlink information. Because Majestic crawls the whole web, it does not have to rely on a third party for the data. You can immediately see the Trust Flow™, Citation Flow™ and Visibility Flow score for any web page directly on the URL bar and you can see summary information about the number of domains and URLs linking to this page.
