Free browser extension
The AnyBacklink extension is a free nofollow and dofollow link checker for your browser. It highlights every link on a page as dofollow, nofollow, sponsored or UGC, and shows how many links sit in the main article.

Backlinks are colour-coded on the page
See how many backlinks are followed within the site copy, and where links are most valuable
Warns you if a page is telling Google not to index or follow its backlinks
Show only links to other websites, or only links inside the article text
Click any link in a page report and jump straight to its location on the page
Opening the AnyBacklink extension on any webpage sorts every link into dofollow, nofollow, sponsored, UGC and internal. The extension also tells you in plain English whether a backlink from that page is worth having.
Turning on highlighting in the AnyBacklink extension outlines every link on the page in colour, so you can see exactly where the dofollow links sit.

A free AnyBacklink account lets the extension show whether the website you’re viewing already accepts backlinks through us. If they aren’t on AnyBacklink, you can still send them a backlink invite from your own email using the extension.
If both sites are verified AnyBacklink members, you can see the keywords your sites share, and a button to send a backlink exchange offer in one click.

When a website is not on AnyBacklink, the extension writes a backlink swap request that includes your Swap With Me link.
The swap request opens in your own email or can be pasted into the website’s contact form, so it always comes from you. If the site owner signs up, your website becomes their first match.

Every link on a webpage is dofollow, nofollow, sponsored, UGC or internal. Only dofollow links to other websites pass ranking value, and dofollow links inside the main article are worth the most.
Dofollow
A dofollow link is a normal link with no rel attribute. Google can follow a dofollow link and count it as a vote for the page it points to.
Nofollow
A nofollow link is marked rel="nofollow", which asks Google not to count it. Nofollow links usually pass little or no ranking value.
Sponsored
A sponsored link is marked rel="sponsored" and is used for paid placements and affiliate links. Google does not count sponsored links as votes.
UGC
A UGC link is marked rel="ugc" and is left by users in comments or forums. UGC links usually pass little ranking value.
Internal
An internal link points to another page on the same website. Internal links help that website, but are not backlinks to anyone else.
