Key takeaways
The best free backlink checker tools in 2026 split into two camps: checkers for your own site and checkers for any domain. For your own site, Google Search Console and Ahrefs Webmaster Tools give full backlink data at no cost. For checking a competitor, Ahrefs' free Backlink Checker and SEO Review Tools show up to 100 backlinks with no signup required.

Is your product missing or out of date?
We review this list regularly. Vendors can request a listing, send updated pricing or ask about featured placement.
None of the seven tools below are the same product wearing a different logo. Some need nothing but a URL. Others need a free account. One calls itself free but is really a 14-day trial. We checked each vendor's own pricing and product page directly for this piece rather than repeating whatever the last "best backlink checker" roundup said, because several of those older claims (a supposedly no-signup tool that now requires one, for example) turned out to be stale.
#1
Ahrefs Backlink Checker
Best for: A fast competitor snapshot without creating an account
Visit ahrefs.com
Starting priceFree
Free planYes, top 100 backlinks per domain, no signup
Ahrefs' public Backlink Checker needs no account or login. Type in any domain and it shows the top 100 backlinks, total backlink and referring-domain counts, and a Domain Rating score for the site. For deeper access to your own site, Ahrefs Webmaster Tools is a separate free product: create a free account, verify you own the domain, and you get full Ahrefs backlink data for that site, not just the top 100 preview shown for other domains.
Signup: none for the public checker; free account plus verification for Webmaster Tools.
What we like- No account or login needed
- Shows the top 100 backlinks, backlink and referring-domain totals and Domain Rating
- Free Ahrefs Webmaster Tools unlocks full backlink data for your own verified site
Watch out for- Only the top 100 backlinks for domains you do not own
- Seeing more than 100 links on someone else's domain requires a paid plan
#2Google Search Console
Best for: Confirming your own site's backlinks with the same data Google uses4.7/5 on
G2 (513 reviews, checked Oct 2026)
Visit search.google.com
Starting priceFree
Free planYes, fully free (your own verified sites only)
Search Console is completely free and needs no credit card, but it only shows backlinks to sites you own and have verified, never a competitor's. Its Links report lists top linking sites, top linked pages, and top anchor text, and you can export up to 1,000 rows per table or up to 100,000 rows through the broader link export. Because it comes straight from Google's own index, it is the most trustworthy source for confirming whether Google has actually registered a specific link to your own site.
Signup: free Google account plus site ownership verification.
What we like- Completely free, no credit card
- Links report covers top linking sites, top linked pages and top anchor text
- Export up to 1,000 rows per table or 100,000 rows through the link export
- Data comes straight from Google's own index
Watch out for- Only shows backlinks to sites you own and have verified, never a competitor's
- Shows a sample of links Google has discovered, not every link on the web
#3
SEO Review Tools Backlink Checker
Best for: A quick, no-login second opinion alongside Ahrefs
Visit seoreviewtools.com
Starting priceFree
Free planYes, up to 100 backlinks per domain, no signup
This one needs no signup for a basic check. Enter a domain or page and it returns up to 100 unique backlinks, sorted by the referring domain's authority, with anchor text and dofollow/nofollow tags included, and a CSV export available. The tradeoff is freshness: the backlink index refreshes monthly rather than continuously, so very recent links may not show up yet.
Signup: none required for a basic search.
What we like- No signup for a basic check
- Up to 100 unique backlinks sorted by referring-domain authority, with anchor text and dofollow/nofollow tags
- CSV export available
Watch out for- Backlink index refreshes monthly, so very recent links may not show up yet
- Capped at 100 backlinks per domain
#4
Semrush Backlink Analytics
Best for: A quick Authority Score check before deciding whether to pay for a full report
Visit semrush.com
Starting priceFree preview (full report on paid plans)
Free planYes, limited preview, no signup
Semrush lets you look up any domain with no signup and see total backlink and referring-domain counts, an Authority Score, and a short preview list of top backlinks with anchor text and link status. The preview is intentionally a small sample rather than the full list. Semrush's own product page describes it as a limited look, and unlocking the complete report and export requires a paid Semrush plan.
Signup: none for the basic preview.
What we like- Look up any domain with no signup
- Total backlink and referring-domain counts plus Authority Score
- Preview of top backlinks with anchor text and link status
Watch out for- The preview is intentionally a small sample
- The complete report and export require a paid Semrush plan
#5
Moz Link Explorer
Best for: Teams that already report on Domain Authority and want a compatible free number
Visit moz.com
Starting priceFree (10 link queries/month)
Free planYes, 10 queries/month, 50 rows each (free account)
Moz requires a free account (email verification, no credit card) to run link queries. The free tier allows 10 link queries a month, returning 50 rows of backlink data per query, alongside Moz's own Domain Authority and Spam Score metrics. That query cap is tight for daily use, but it is a genuinely permanent free tier rather than a trial.
Signup: free Moz account required.
What we like- Permanent free tier, not a trial
- Includes Moz's Domain Authority and Spam Score
- Free account needs only email verification, no credit card
Watch out for- 10 queries a month is tight for daily use
- Requires a free Moz account
#6Ubersuggest
Best for: Users who already run keyword research in Ubersuggest and want backlinks in the same place4.2/5 on
G2 (160 reviews, checked Oct 2026)
Visit neilpatel.com
Starting priceFree (3 searches/day)
Free planYes, 3 searches/day, up to 100 backlinks each (free account)
Ubersuggest's free tier requires a free Neil Patel account and limits you to 3 searches a day, with each backlink search showing up to 100 backlinks for the domain checked. It lives inside the same dashboard as Ubersuggest's keyword and site audit tools, so it is convenient mainly if you are already using those for free.
Signup: free account required.
What we like- Backlinks sit in the same dashboard as Ubersuggest's keyword and site audit tools
- Each search shows up to 100 backlinks
Watch out for- Limited to 3 searches a day
- Requires a free Neil Patel account
#7
SE Ranking Backlink Checker
Best for: A short, deep one-time audit, not an ongoing free habit
Visit seranking.com
Starting priceFree 14-day trial, then a paid subscription
Free planNo, 14-day free trial only
SE Ranking requires a free account, and what it calls a free backlink checker is really a 14-day free trial of its full platform rather than a permanent free tier. During those 14 days you get full access to its backlink database, which SE Ranking's own site reports at roughly 2.7 trillion backlinks and 420 million domains indexed. After the trial window closes, continued access requires a paid subscription.
Signup: free account, functions as a 14-day trial.
What we like- Full access to its backlink database during the trial
- SE Ranking reports roughly 2.7 trillion backlinks and 420 million domains indexed
Watch out for- What it calls a free checker is really a 14-day trial of the full platform
- Continued access requires a paid subscription
Of the seven tools above, three work with no signup at all for a basic lookup (Ahrefs' public checker, SEO Review Tools, and Semrush's preview), while four require creating a free account, and one of those four (SE Ranking) is a time-limited trial rather than a permanent free tier.
Which free backlink checker shows the most backlinks?
For a single free lookup with no account, Ahrefs' Backlink Checker and SEO Review Tools both cap out at the top 100 backlinks per domain. For a fuller picture on an ongoing basis, Google Search Console shows your complete backlink data through its export tools, but only for sites you own and have verified, not competitors. If you need more than 100 links on a domain you do not own, every option on this list eventually requires a paid plan.
Can I check my own site's backlinks completely free?
Yes. Google Search Console shows every backlink Google has verified to your site once you confirm ownership, at no cost and with an export covering up to 100,000 rows. Ahrefs Webmaster Tools is a second free option: create a free Ahrefs account, verify your domain, and you get full Ahrefs backlink data for that site rather than the 100-link preview the public checker gives for other domains. Running both side by side is a reasonable free habit, since they draw on different indexes and occasionally catch different links.
Are free backlink checker results accurate enough to trust?
The numbers you see are accurate as far as they go, but they are incomplete by design. Every free tier on this list caps results, whether by row count, query count, or days of trial access, so a competitor's real backlink profile is almost always larger than what shows up for free. Free checkers are good for spotting obvious gaps and quick wins; treat a full paid report as the source of truth before you make a real budget decision based on what you find.
This comparison is based on each vendor's own pricing and product pages as of August 2026, not paid trials of every platform. Where a vendor's marketing copy did not state an exact limit, such as the precise size of Semrush's free preview, we describe it honestly as unspecified rather than inventing a number. Four things actually separate these tools in practice: whose site you can check, how many results the free tier reveals, how often the underlying data refreshes, and whether the "free" label is permanent or a disguised trial.
For the manual side of earning links in the first place, our guide to building backlinks walks through outreach step by step, and our link building tools comparison covers the paid platforms once free lookups stop being enough. Once new links start landing, our rank tracking tools comparison covers measuring whether they actually moved rankings.
Frequently asked questions
What is the best free backlink checker tool in 2026?
There is no single best free backlink checker for every case. For checking your own site, Google Search Console is free with no result cap. For checking a competitor without creating an account, Ahrefs' Backlink Checker and SEO Review Tools both show up to 100 backlinks. If you need a deeper one-time look, SE Ranking's 14-day free trial unlocks its full database temporarily.
Is Ahrefs' backlink checker really free?
The public Ahrefs Backlink Checker is free with no signup, but it only shows the top 100 backlinks to any domain plus summary totals. Ahrefs Webmaster Tools is a separate, also-free product that requires a free account and site verification, and it unlocks full backlink data, though only for sites you own.
How many backlinks can I see for free?
It depends on the tool. Ahrefs and SEO Review Tools both cap free results at 100 backlinks per domain. Semrush shows a smaller preview sample. Google Search Console and Ahrefs Webmaster Tools show your full backlink count, but only for your own verified site.
Can I check a competitor's backlinks without paying?
Yes, within limits. Ahrefs' Backlink Checker, SEO Review Tools, and Semrush's preview all let you check any domain, including competitors, for free with no signup for a basic look. None of them hand over a competitor's complete backlink list for free; that requires a paid plan on any of these platforms.
What is the difference between Ahrefs Backlink Checker and Ahrefs Webmaster Tools?
The Backlink Checker is a public tool anyone can use on any domain, free, with no account, capped at the top 100 backlinks. Ahrefs Webmaster Tools requires a free account and proof you own the site, but in exchange it unlocks full backlink data, site audit, and keyword ranking information for that verified site only.
Does Google Search Console show all my backlinks?
It shows a sample of the links Google has discovered and verified to your site, not literally every link that exists on the web. The Links report includes a broader export of up to 100,000 rows, which covers the vast majority of sites, but Search Console has never claimed to be a complete crawl of the entire internet.
Is Moz Link Explorer free forever?
Yes, Moz's free account is a permanent tier, not a time-limited trial. It is limited to 10 link queries a month with 50 rows of data per query, which is enough for occasional checks but too restrictive for daily competitor research.
Is SE Ranking's backlink checker actually free?
Not in the permanent sense. What SE Ranking calls a free backlink checker requires signing up and functions as a 14-day free trial of its full platform. After the trial ends, continued access requires a paid subscription, which makes it more of a trial than an ongoing free tool like Google Search Console or Moz's free tier.
How often do free backlink checkers update their data?
It varies by vendor and none publish an exact crawl frequency for their free tier. SEO Review Tools states its backlink database refreshes monthly. Ahrefs and Semrush crawl continuously across their platforms, though free-tier users typically see more lag than paid accounts. Google Search Console updates as Google's own crawlers discover and process links, which is not instantaneous either.
Is your product missing or out of date?
We review this list regularly. Vendors can request a listing, send updated pricing or ask about featured placement.
