Free Backlink Checker: Check the Backlinks of Any Website
A backlink checker is a tool that lists and counts the links pointing to a website from other sites. To check backlinks, enter any domain above, yours or a competitor's, and this checker reports its live backlinks, referring domains, dofollow vs nofollow links, anchors, link types and countries, then explains what the numbers mean. It is free with an account.

About this tool
What the report contains: every link from another website to the domain you enter is a backlink, and the report groups them the ways that matter for SEO. You get total live backlinks, referring domains (the number of different websites linking), referring IPs and subnets (how many separate servers those sites use), the dofollow and nofollow split and a link rank from 0 to 1000. Below that come broken backlinks, the date the index first saw a link and, when the index gives one, a backlink spam score, then tables of link types, top-level domains, countries, kinds of linking sites, the top anchor texts when the index carries them, and a plain-language reading of your numbers.
Where the data comes from: a commercial link index that crawls the web continuously. The report covers live links to the whole domain, subdomains included, and a domain's link data is cached on our server for up to 7 days, so a repeat check within the week shows the same figures. No crawler finds every link, so treat each number as a large sample and compare sites with the same tool. Running a check needs a free account because every lookup is a paid query to that index; this page and the guide below are open to everyone.
How to check backlinks of any website
- Type the domain into the box above, such as example.com. A full URL works too: the checker reads the whole domain, subdomains included.
- Press Check Backlinks. The live data needs a free account, and the line under the button shows how many runs are free and what a run costs after that.
- Read the summary tiles first: backlinks, referring domains, referring IPs and subnets, followed and nofollow links, and the link rank.
- Scroll to the tables of link types, top-level domains, countries and kinds of linking sites, and the top anchor texts when the index carries them.
- Finish with "What the numbers mean", a plain-language reading written from your own figures, then run the same check on two or three competitors.
How to read the result: a worked example
The figures below are made up for a fictional site, example.com, to show the arithmetic. They are not data for any real domain; run the checker above to see the real numbers for yours.
| In the report | Example | How to read it |
|---|---|---|
| Backlinks | 600 | Every live link from another site. On its own it says little, because one site can link thousands of times. |
| Referring domains | 150 | The number of different websites linking. This is the number to compare with competitors and to grow. |
| Links per referring domain | 4 (600 divided by 150) | Near 1 to 5 means the links are spread across many sites, the healthy pattern. Dozens per site usually means sitewide footer, sidebar or blogroll links, which count for far less. |
| Referring IPs | 140 | Close to the domain count, so the linking sites sit on many separate servers. Far fewer IPs than domains can point to a network of sites with one owner. |
| Nofollow links | 240 (40 percent) | A normal mix. Profiles, forums and social sites add nofollow links, and a large profile with almost none is worth a closer look. |
| Top anchor | Example (the brand name) | Healthy. When an exact-match money keyword is the top anchor, that is the pattern Google's link spam systems look for. |
| Broken backlinks | 12 | Links to pages on example.com that now return an error. A 301 redirect to the closest live page wins their value back. |
| Link rank (0 to 1000) | 310 | The link index's own score, not Moz Domain Authority or Ahrefs Domain Rating. Compare it only with other domains checked here. |
Reading the example as a whole: example.com earns its links from many separate sites on many separate servers, with a normal share of nofollow links and the brand as the top anchor. Nothing there looks built. Its next step is more referring domains, not more links from sites that already link, and the twelve broken backlinks are quick wins. Your own result ends with the same kind of reading, written from your real numbers.
Competitor backlink checker: find the gap
Run the same check on the three sites ranking above you for your main keyword. The gap in referring domains tells you how much link building stands between you and them, and the kinds of sites linking to them, such as directories, industry blogs, resource pages and news, are your prospect list.
Then turn that list into a plan. The Backlink Opportunity Finder gives you an ordered list of legitimate link sources for your niche, business type and country, and the Domain Authority Checker tells you whether a prospect has real authority before you spend time pitching it.
Dofollow vs nofollow backlinks
A dofollow link is an ordinary link with no rel attribute, and search engines may treat it as a vote for the page it points to. A nofollow link carries rel="nofollow", rel="sponsored" or rel="ugc", which asks search engines not to pass that credit. Google treats these attributes as hints rather than commands, but such links still carry far less weight.
Nofollow links are normal on social profiles, forums, directories and comments, and they do not hurt a site. A profile that is mostly nofollow usually means the links came from profiles and directories rather than editorial mentions. Because Google asks for paid links to be marked rel="sponsored" or rel="nofollow", a healthy profile always contains some nofollow links. For places that still give followed links, see our list of 1000+ dofollow backlink sites, grouped by type.
Referring domains vs total backlinks, and what anchor text tells you
The referring domain count matters far more than the backlink total. A thousand backlinks from one website, usually a sitewide footer, sidebar or blogroll, carry roughly the weight of a single endorsement, while fifty links from fifty relevant websites are fifty endorsements. Divide backlinks by referring domains: a ratio near 1 means links spread across many sites, a ratio in the dozens means sitewide links.
Anchor text is the other thing to read. In a natural profile the biggest anchors are the brand name, the bare domain and plain words such as "website" or "here", with exact-match keywords a small minority. When your money keyword is the top anchor, that is the pattern Google's link spam systems look for, and the safe fix is to earn new links with brand and descriptive anchors. Automated lookup-page links, the kind old backlink generators made, add backlinks without adding endorsements; our Backlink Maker says plainly what they are worth.
Free backlink checkers compared
Every link index runs its own crawler and finds a different share of the web, so no free tool, ours included, shows every link, and no two tools report the same counts. This is how the common free options work at the time of writing (November 2026). Free plans change often, so confirm the current limits on each vendor's own page.
| Tool | Account needed? | Kind of limit | What it shows |
|---|---|---|---|
| SEO SMO HUB Backlink Checker (this page) | Yes, a free account | A free allowance, then credits; the line under the button shows the current offer | Whole-domain totals: backlinks, referring domains, IPs and subnets, followed and nofollow, link types, TLDs, countries, broken backlinks, anchors when available, and a plain-language reading. It does not list every linking page. |
| Ahrefs free Backlink Checker | No | Shows a sample of the strongest links; complete lists need a paid plan | Domain Rating, URL Rating, backlink and referring domain totals, and the top backlinks with their anchors |
| Ahrefs Webmaster Tools | Yes, and you verify the site | Only sites you own and verify | Backlink reports for your own sites |
| Semrush | Not for the free checker's preview; a free account for more | Free accounts get a small daily allowance; full reports need a paid plan or a trial | Authority Score, backlinks, referring domains, dofollow share, anchors, new and lost links |
| Moz Link Explorer | Yes, a free Moz account | A small free query allowance; more with Moz Pro | Domain Authority, Page Authority, Spam Score, linking domains and top links |
| Ubersuggest | Not for the first searches; an account for more | A small number of free searches a day | Its own domain authority score, backlinks, referring domains, new and lost links |
| Google Search Console (Links report) | Yes, and you verify the site | Only sites you own and verify | Top linking sites, top linked pages and top linking text from Google's own data, with no authority score |
Which to use: for your own site, start with the Links report in Search Console, because it is Google's own data. For competitors, pick one tool and stay with it, because numbers from different indexes cannot be compared. This checker is built for that quick comparison, with a plain-language reading of the numbers; for a page-by-page export of every link, use a paid index. If you would rather hand the work over, our SEO service runs the competitor gap analysis and monthly white-hat outreach, and reports every link earned.
Backlink tracker and backlink analyzer: how often to check
Check your own domain monthly, and two to four weeks after any outreach campaign, to see which new links the index has found and whether old ones were lost. New links take days or weeks to be discovered, so daily checks show mostly noise. Note the referring domains, the dofollow share and the top anchors each time, and compare month with month.
A sudden jump in backlinks from a country or top-level domain you do not sell in is the usual first sign of spam links pointed at you. Google normally ignores those on its own; a disavow file is only worth filing for links you built or bought, or after a manual action. For automated alerts and the full history of every link, you need a paid index.

Frequently asked questions
What is a backlink checker?
A backlink checker is a tool that finds and counts the links pointing to a website from other sites. It reports the total backlinks, the number of different referring domains, the dofollow and nofollow split, anchor texts and where the links come from, so you can judge a site's link strength and see where competitors earn their links.
How do I check the backlinks of a website for free?
Enter the domain in the box above, such as example.com, and press Check Backlinks. You need a free account, and the line under the button shows how many checks are free. The report gives live backlinks, referring domains, followed and nofollow links, anchors and a plain-language reading. For a site you own, the Links report in Google Search Console is free too.
How do I check my competitor's backlinks?
Run the checker on the competitor's domain exactly as you would on your own. Compare their referring domains with yours to measure the gap, then look at the kinds of sites linking to them: directories, industry blogs, resource pages, news. Those sites already link to a business like yours, which makes them the best outreach prospects you can find.
What is the difference between dofollow and nofollow backlinks?
A dofollow link is a normal link that search engines may count as a vote for the page it points to. A nofollow, sponsored or ugc link asks them not to pass that credit. Both belong in a natural profile, and because Google asks for paid links to be marked sponsored or nofollow, a share of nofollow links is normal and safe.
Why do referring domains matter more than total backlinks?
A referring domain is one website that links to you, however many times. Search engines weigh the number of independent sites far more than the raw link count, because a sitewide footer on one blog creates hundreds of backlinks but only one endorsement. Fifty links from fifty relevant sites beat a thousand from one, so track referring domains first.
What is the best free backlink checker?
There is no single best one, because each index finds a different share of the web. Ahrefs' free checker shows the strongest links without an account, Semrush and Moz give limited reports on free accounts, and Google Search Console is the free choice for your own site. Pick one tool and use it consistently when you compare sites.
Why are my numbers different from Ahrefs, Semrush or Google Search Console?
Every link index runs its own crawler, so each finds a different share of the web and drops lost links on its own schedule; Search Console shows only a sample of what Google knows. This checker reports whole-domain totals and breakdowns, not every linking URL, so treat any number as a large sample and compare competitors with the same tool.
How often should I check my backlinks?
Monthly is enough for most sites, plus one check two to four weeks after a link building campaign. Search engines and link indexes take days or weeks to find new links, so daily checks mostly show noise. Watch the referring domain count, the dofollow share and the top anchors over time rather than the raw backlink total.
