Frequently asked questions

What is a backlink?

A backlink is a link from another website to yours. Search engines treat good backlinks as votes of trust, so they are one of the strongest ranking signals.

What is a referring domain?

A referring domain is a unique website that links to you. Ten links from one site count as one referring domain, which is why referring domains matter more than the raw backlink count.

What does dofollow mean?

A dofollow link passes ranking value to the page it points to. Nofollow links (rel=nofollow, sponsored or ugc) ask search engines not to pass that value.

What is domain rank?

A 0-1000 score from DataForSEO based on the quality and quantity of links pointing to a domain. Higher means a stronger backlink profile.

Can I check a competitor's backlinks?

Yes. Enter any public domain. Competitor backlinks are one of the best sources of link building ideas.

Is this backlink checker free?

Yes. The backlink checker is free with no signup. Because each lookup uses paid backlink data, each visitor can run a limited number of checks per hour.

How do I check backlinks to my website?

Enter your domain above and press Check backlinks. You will see your referring domains, total backlinks, dofollow share and your strongest backlinks with their anchor text.

Why are backlinks important for SEO?

Backlinks from relevant, trusted sites tell Google your content is worth ranking. Pages with more quality referring domains usually rank higher.

Why does my site show few backlinks?

New sites often have few links, and backlink indexes take time to find new ones. Focus on earning links from relevant sites; the count will grow as they are discovered.

How can I get more backlinks?

Publish content worth citing, reach out to sites that link to your competitors, and get listed in relevant directories. Outrank can also build backlinks for you automatically.
