Enter a keyword... : This field lets you narrow your results to specific keywords from the domain that you entered. For example, if you type "calendar," it will show you backlinks going to the domain's pages that rank for keywords like "content calendar" or "custom calendar gifts."

Backlink Types: You can filter your results by certain categories or page types. Check the box next to one or more page types, and the results will automatically reset to reflect your choices.
Blogs: These pages are designated as blogs by the domains that run them, or they are hosted on popular blog platforms like Blogspot.
News: Many news pages aggregate stories from other sources, often with an original summary and a link to more information on another site. They frequently appear at the top of a search because the relevant content is more timely. Getting a link to your site will probably come in the form of a press release that they pick up.
Has Affiliate Links: Results in this category have links on their page that connect to an affiliate program. The page owner is paid for any sales they get for a 3rd party service/product through the links on their page. A pet training blog could have affiliate links to Petsmart.com, Petco.com, and GenuineDogGear.com. Being in this category does not guarantee that the affiliate link is specifically for the domain that you searched.
.GOV /.EDU: Pages ending in these top-level domains (like irs.gov or cornell.edu) belong to government entities or educational institutions. They are traditionally more structured than commercial or individually-run pages, so getting a link from one to your own site could be challenging. However, they tend to be seen by Google as strong authorities, so they often rank higher on searches and pass along stronger “link juice.”
Forums: These pages are community forums, usually open to anyone to read but often requiring a sign-in to comment or update a post. Because forums are community-built content, they are usually the easiest route to add your own link back to your domain. In that vein, forums generally don’t pass as much link juice as other types of pages.
Hidden Domains
The “x” next to each listed backlink lets you hide that link and every link from that domain. Any domains that you hide will be listed here. You can click the “x” in this section to unhide those results in the backlinks list.
Backlink Kombat
If you enter two domains, the filter will find the pages that link to both of those pages. Type your own domain into the exclude box, and the combination finds backlinks that your competitors get but you do not.
Backlink Results
Every page here links at least one time to the domain that you searched. This might be a smaller set than what is actually on the domain's page. That's because we remove duplicates and show only links that have been indexed by Google. This helps you to avoid questionable links.
Domain Monthly Organic Clicks
The domain in this case is not the one you searched, but the one that is linking to your target. (It's the domain of the backlink.) The domain’s monthly organic clicks helps you see how much traffic they got this past month to all of its pages from unpaid search results.
We estimate these clicks using the domain’s rank and the organic click-through rate for the keywords it ranks on.
Page Monthly Organic Clicks
We estimated the number of clicks that each specific page gets in a month from all of its organic rankings.
Domain Strength
We rate domains to show how strong they are in a niche so that you can gauge how important a link from that site would be. A domain with a high score here (closer to 100) consistently ranks on top searches. It pulls in high amounts of quality traffic, and it carries high authority across many competitive keywords.
Ranked Keywords: We count the number of keywords that the backlink page ranks for. If you click the number, it will open a page dedicated to the page so that you can see what those individual keywords are.
Outbound links
This metric counts the number of separate URLs that this page links to. If you hover over the number, it will list the domains that the page points to.
