Every backlink metric that matters

One scan returns the numbers that actually tell you how strong a link profile is.

Referring domains

The unique websites linking to you, the single best measure of link strength.

Total backlinks

Every inbound link pointing to the page, counted and listed.

Dofollow & nofollow

The follow mix, so you know how much link equity is actually being passed.

Broken backlinks

Dead links pointing at your page that are leaking value you could recover.

Anchor text

The words other sites use to link to you, and whether they fit your keywords.

Competitor backlinks

Run the same backlink analysis on any competitor to see the referring domains behind their profile.

Your site or a competitor’s

Check the backlinks of any website

Enter your own URL to see the backlinks pointing to your site, or a competitor’s to see the referring domains and links behind their profile. Reviewing a competitor’s backlinks is one of the fastest ways to spot link opportunities worth pursuing.

Why backlinks matter

Links are still one of Google’s strongest signals

Search engines treat inbound links as votes of trust. Links from many different, reputable domains carry far more weight than lots of links from a single site, and dofollow links pass authority while nofollow links do not. Knowing your backlink profile tells you how much link equity your pages have earned, and where to build more.

Frequently asked questions

What is a backlink checker?

A backlink checker shows the links from other websites that point to a page, along with the metrics behind them: how many referring domains link to you, the anchor text they use, the dofollow and nofollow mix, and any broken backlinks.

How do I check a website’s backlinks?

Paste any URL into the backlinks checker and run a scan to see the inbound links pointing to that page, the referring domains behind them, and the health of the link profile, whether you want to check your own backlinks or a competitor’s.

What are inbound and incoming links?

Inbound links, also called incoming links or backlinks, are links from other websites to yours. They are one of the strongest ranking signals, because search engines treat them as votes of trust. This inbound link checker surfaces every inbound link pointing to a page and the domains behind them.

What are referring domains, and why do they matter?

Referring domains are the unique websites that link to you. Ten links from ten different domains are worth far more than ten links from one, so referring domains are often a better measure of link strength than raw backlink count.

What is the difference between dofollow and nofollow links?

Dofollow links pass authority to the target page and can help it rank. Nofollow links do not pass authority, but still send traffic, and a natural link profile has a healthy mix of both.

Can I check a competitor’s backlinks?

Yes. Enter any URL, your own or a competitor’s, to see its backlink profile. Reviewing a competitor’s backlinks is one of the fastest ways to spot link opportunities worth pursuing.

How is this different from Ahrefs or Semrush?

Ahrefs and Semrush cap their free backlink checkers to a handful of links and push you to a paid plan. DefiniteSEO shows you the referring domains, dofollow and nofollow mix, anchor text and broken links in one free instant scan.

How many backlinks do I need to rank?

There is no fixed number. Quality and diversity beat quantity: a few links from trusted, relevant domains will move you further than hundreds of low-quality links. Focus on earning links from sites your audience already trusts.
