Free backlink checker
Enter a domain: you get every site linking to it, the authority of each one, and
the exact page carrying the link with its anchor text. No account, no credit
card, no list cut down to three rows.
What this backlink analysis gives you
The referring domains
Every domain pointing to yours in the current version of the graph, sorted by descending
authority. The first number anyone looks at in a backlink audit.
An authority score you can verify
A 0 to 100 score per referrer, computed over the 2.45 billion links of the graph. The
computation is public: you can redo it.
The linking page and its anchor
The graph stops at the domain. The tool goes and finds the exact address, the clickable
text and the rel attribute. That is what most free checkers never
give you.
A complete CSV export
Everything on screen leaves as CSV in one click, with no row cap and without creating an
account.
Where these backlinks actually come from
From the Common Crawl link graph, the largest public crawl of the web. Every
quarter, Common Crawl publishes the domain-to-domain links recorded during its crawl:
2.45 billion links in the current version. This tool keeps a precomputed index of
1.14 billion inbound links to
78.7 million domains, for the extensions .fr, .net, .org, .com, .de, .io, .app, .pro, .ai, .dev, .vision, .ch, .be, .it, .es, .nl, .ca, .info, .eu, .community, .paris, .bzh, .alsace, .corsica, .quebec, .shop, .online, .site, .store, .blog, .day, .co, .africa, .top, .lol, .ma and .cloud.
That origin is the real subject, and it deserves to be stated plainly rather than hidden
behind a brand name:
| What it gives you | What it costs you |
|---|
| Auditable numbers. The source files are public and downloadable. If a
figure surprises you, you can trace it back to the line of the graph that produced it. |
A sample, not a census. A link that exists but whose source page was
never crawled does not appear. Totals are a floor. |
| No reason to ration. The data costs nothing to read again, so there is
no daily quota, no account to create, no truncated list designed to push you towards a
subscription. |
A quarterly snapshot. The graph follows the rhythm of Common Crawl
releases. A link placed yesterday will not be there before the next one. |
| The same tool for everyone. Your site, a competitor's, a prospect's:
nothing is reserved for the domain owner. |
No history. This tool tells you who links to you today, not what you
gained or lost last month. |
Finding the page that carries the link
This is the limit every tool built on a public graph shares: it works at domain level. It
knows that example.com cites you, never from which page, nor with what
anchor text. Yet that is exactly what you want to know: on which words a site linked to you, and
whether the link is nofollow.
So the « find the URL » button on each row goes and asks elsewhere, in six passes,
from the fastest to the most expensive:
- the RSS feed of the source site's own search, when it publishes one;
- its usual search URLs, reading result titles rather than menu links;
- its sitemap, the only way in for directories with no internal search;
- its POST search form, anti-replay token and session cookie included, for
sites that accept nothing else;
- a Google query using site:, for sites whose
internal search runs in JavaScript and returns nothing to a robot;
- the Common Crawl archives, as a last resort, when the page has vanished
from the live site.
Every page found is then read back for verification: the tool does not settle
for « the page should be there », it goes and reads the actual
<a href>. When the page exists, mentions you, but no longer links
to you, it says so: that is a link lost since the crawl, and nobody else will
tell you.
How to read the authority score
The 0 to 100 score next to each referring domain is a harmonic centrality: it
measures how close a domain sits to the rest of the web when you follow links. Two practical
consequences.
It resists inflation. A thousand links bought from sites nobody cites bring
you closer to nobody, so the score does not move. A single link from a site everyone cites
does.
It does not measure volume. A domain can have few inbound links and a high
authority, because the ones it has come from the right place. Do not mistake the score for a
backlink counter: the full ranking is
browsable by country and by extension.
What this tool does not do
Saying so saves your time, and it is the best way to show you where its measurement stops.
- No tracking over time: no curve, no lost-link alert. One analysis, at the
moment you ask for it.
- No estimated traffic: this tool counts links, it does not guess
visits.
- Not Google's truth: nobody has access to it, here or anywhere else.
- Not every extension: 37 are precomputed. The others go
through the full report, computed overnight and sent by email.
Frequently asked questions about backlink analysis
How do I check the backlinks of a website?
Enter the domain in the field above. The tool reads a backlink index precomputed from the link graph Common Crawl publishes every quarter. It returns every domain pointing to that site, sorted by authority. No account is asked for. The list is not cut down to three rows to push you into signing up.
Is this backlink checker really free?
Yes, with no strings attached: no sign-up, no credit card, no email address to see the result. The reason is simple: the underlying data is public. Common Crawl publishes its link graph openly. The expensive part, turning 39 GB of raw graph into a queryable index, has already been done once and for all.
Are these the backlinks Google knows about?
No, and no tool on the market can honestly claim otherwise: nobody has access to Google's index. What you see here are the links recorded by Common Crawl's public crawl. It is a broad sample but still a sample: the numbers are a floor, never a total. A real link whose source page was never crawled will not show up.
Can I check a competitor's backlinks?
The same way: enter their domain instead of yours. Nothing is reserved for the owner of a site, since the tool only reads public data. That is the most common use of a backlink analysis: seeing who cites a competitor, and on which anchor text, to know which pages are worth approaching.
Why is the linking page not shown straight away?
Because the Common Crawl graph works at domain level: it knows that example.com points to you, never from which page. Finding the exact address means querying the source site, which takes a few seconds per domain. The « find the URL » button does it on demand. It also brings back the anchor text and the rel attribute.
What is the authority score worth?
It is a harmonic centrality computed over the 2.45 billion links of the full graph, mapped onto a 0 to 100 scale. It measures how close a domain sits to the rest of the web, which makes it resistant to inflation: buying a thousand links from sites nobody cites moves nothing. The computation is public and reproducible, unlike the proprietary scores of the market.
Can I export the backlinks?
Yes, as CSV, in one click, with no row limit and no account. The file lists the referring domains and, for those whose page was found, its address and anchor text.
My extension is not covered, what now?
The precomputed index covers 37 extensions, the ones that answer the vast majority of requests. For the others, the page offers a full report: the question is queued, the entire graph is re-read overnight, and the result arrives by email. Same data, simply not precomputed.
