Open data you can explain.
The index is built from a public dataset, so you know where the numbers come from and how often they refresh.
- Monthly Common Crawl processing
- Links from our own crawler added
- Coverage smaller than commercial indexes
A backlink checker built on an open web graph
See who links to you, with which anchor text and when the link was first and last seen, using open web data processed every month.

How does this backlink checker get its data?
BigRank builds its backlink index from Common Crawl, a free open dataset of about 3 billion pages crawled monthly. Each month it scans a share of that crawl's link data for links that point to customer and competitor domains, and adds the links its own site audits find.
- How fresh is the data?
- Monthly. New domains get page-level data at the next monthly run.
- How big is the index?
- It is a sample: each monthly crawl is scanned in part, so the index is smaller than commercial ones. That is the trade-off for open data.
- What is shown for each link?
- Source URL, target URL, anchor text, dofollow or nofollow, first seen, last seen and source authority.
- Does it find risky links?
- A spam risk heuristic flags low authority, link-farm patterns, irrelevant TLDs and sitewide footer links.
What the backlink audit includes
Links come from a share of Common Crawl's monthly crawl, plus the links our own site crawler finds. A link counts as lost only when its page was crawled again without it.
Open web index
Links come from Common Crawl's monthly crawl, processed into a link graph that we keep for your domains and your competitors'.
- Common Crawl link metadata
- Processed once a month
- Your domains and competitors' domains
Source and target pages
See which page links to which of your URLs.
- Source URL and target URL

Anchor text distribution
Anchors are grouped as branded, exact match, generic or URL, so you can see how natural your profile looks.
- Branded and exact match
- Generic and URL anchors
- Share of each anchor type
Dofollow and nofollow
Each link is marked so you know which ones pass authority.
- Dofollow or nofollow per link
- Dofollow share per linking domain

New and lost links
A monthly comparison shows links that appeared since the last snapshot and those that are gone.

From audit to cleanup
A backlink audit works best as a monthly routine that matches the data: review the new snapshot, deal with what changed, and keep cleanup decisions in one place.

When teams audit backlinks
Backlink data answers questions about trust from other sites: where your links come from, which ones you lost, whether the profile looks natural, and where competitors earn links you don't.
Link profile reviews
Understand where your links come from and how they are worded.
Lost link recovery
Find links that disappeared and ask for them back.
Penalty prevention
Spot unnatural patterns before they become a problem.
Competitor comparison
Compare profiles with the Backlink Gap view.

Backlinks connect to the rest of your SEO work. Review the domains behind them, fix the broken pages links still point to, and keep risky ones in your disavow list.
Backlink Checker FAQ
Answers about plan availability, where the index comes from, coverage, backlinks to broken pages, crawler-found links, data for new domains and how lost links are found.
Which plans include backlinks?
Max and Ultra. Pro does not include backlinks.
Why is coverage smaller than paid tools?
The index uses open data and monthly processing instead of a commercial crawler.
Can I find backlinks pointing at broken pages?
Yes. Backlinks that point to your 4xx or 5xx pages are listed so you can redirect them.
Are my own crawl findings used?
Yes. Links discovered by the site crawler are added as a supplementary source.
When does a newly added domain get data?
Domain-level data is available right away. Page-level backlinks arrive with the next monthly run.
How are lost links found?
Each monthly snapshot is compared with the previous one. Links that were there before and are missing now are listed as lost.
