How to Check Backlinks to Any Page for Free

What's the fastest free way to check backlinks?

The fastest method depends on whether you own the page. If it's your site, Google Search Console gives you a full list of external links with no artificial cap — you just need to verify ownership first. If it's someone else's page, no free tool sees the entire web, so you cross-check a crawler-based tool like Ahrefs or Moz against whatever Search Console data you can access.

Both routes tell you who links to a page and what anchor text they used. Neither requires installing anything, because this is a job for a web tool, not a browser extension — backlink data comes from a server-side crawl of the entire web, not from what renders in your tab.

Before you start, decide what you actually need: a one-off spot check on a single URL, an ongoing watch on your own domain, or a full competitor audit. A one-off check is free everywhere. An ongoing watch is free and unlimited in Search Console for your own site. A full competitor audit at scale is the one job that eventually pushes people toward a paid plan, because free tiers cap how many rows and how many daily lookups you get.

How do I check backlinks to my own site for free?

Search Console is the only completely free backlink source with no row limit — but only for domains you've verified you own.

1. Go to Google Search Console and sign in with the Google account tied to your site.
2. Select your verified property, or add one using the domain or URL-prefix method if you haven't yet.
3. In the left sidebar, click Links.
4. Under External links, open Top linking sites and Top linking pages.
5. Click any site name to see the exact pages linking to you and the anchor text they used.
6. Use the export button to download the full external links list as a CSV for offline sorting.

This report only shows links Google has crawled and chosen to index, so it won't be literally every backlink that exists anywhere — but it's the most accurate free view of your own site specifically, since it comes straight from Google's own index rather than a smaller third-party crawl.

How do I check backlinks to a page I don't own?

For any page you don't control — a competitor's site, a guest post you wrote, a broken outreach link — you need an independent backlink index like Ahrefs' Backlink Checker or Moz's Link Explorer, since Search Console only ever covers verified properties.

These tools work by crawling large parts of the web on a schedule and storing the link graph they find, so you can look up any URL or domain without needing access to that site's account. The trade-off is coverage: no crawler sees the whole web at once, and free tiers only unlock a capped slice of what each tool has indexed.

Run the same URL through two of these and compare the results side by side. Because each tool's index is built independently, you'll often see different totals — that's normal, not a sign either tool is wrong, and it's exactly why there's no single answer to which backlink checker is most accurate.

What do DA, DR and toxic score actually mean?

DA, DR and toxic scores are estimates produced by the tool you're using, not numbers Google publishes or uses directly. Treat them as a rough proxy for authority, not a ranking factor.

DA (Domain Authority)

Moz's 1–100 estimate of how likely a whole domain is to rank well, based on the quantity and quality of its link profile.

DR (Domain Rating)

Ahrefs' equivalent 0–100 score, calculated from the number and strength of unique referring domains pointing at a site.

Referring domain

A distinct website linking to a page — more useful than a raw backlink count, since one site can link to you dozens of times.

Toxic score

A tool's estimate of how spammy or unnatural a link looks, based on patterns like link farms, hacked sites, or stuffed anchor text.

None of these scores are interchangeable between tools — a DA of 40 and a DR of 40 aren't measuring the same thing, since each company built its own model on its own index. If you're comparing your site to a competitor, stick to one tool's score for both sides rather than mixing an Ahrefs number with a Moz one.

How do I know if a backlink is good or harmful?

A good backlink comes from a real, topically related site with actual content around it. A harmful one comes from a link farm, a hacked page, or a directory stuffed with exact-match keyword anchors — and you can usually tell the difference by eye in under a minute.

• Does the linking page have real writing around the link, or is it a bare list of outbound URLs?
• Is the site even loosely related to your topic, or completely unrelated to it?
• Does the anchor text read naturally, or is it stuffed with an exact-match keyword phrase?
• Is the domain indexed in Google at all? Search site:domain.com to check.
• Does the same page link out to other obviously spammy or unrelated sites?
• Was the link added suddenly, in a batch alongside dozens of near-identical ones?

Which browser extensions help while auditing backlinks?

No credible backlink checker runs as a plain browser extension, because the data comes from a server-side crawl of the entire web, not from what loads in your tab. What extensions can do is remove friction from the manual side of a review — reading, saving and translating the pages you've already flagged.

Any extension that reads or summarizes page content needs some level of access to what you're browsing, so it's worth knowing what you're granting — see our plain-English guide to extension permissions before installing one. For more single-purpose tools like these, browse Find Extensions' SEO audit extension picks, our guide to translating a web page in Chrome, or the wider collection of free Chrome extensions worth installing.

Are backlinks still relevant in 2026?

Yes — backlinks are still one of the clearest trust signals search engines and AI answer engines use to judge whether a page is worth citing. A link from a relevant, well-regarded site is still one of the hardest signals to fake, which is exactly why it keeps mattering even as ranking systems get more sophisticated.

What's changed is emphasis, not existence. Modern ranking systems weigh the relevance and quality of the linking page far more heavily than raw link count, and the same logic shows up in how large language models decide which sources to summarize or cite: content that's genuinely referenced elsewhere is more likely to be treated as a trustworthy source. A page with zero external references, however well written, has a harder time earning that trust from either a search engine or an AI answer engine.

That's also why backlink audits are worth repeating rather than doing once. New links, and new spam, show up continuously, and a link profile that looked clean a year ago can shift as old pages get removed, redirected, or picked up by low-quality scraper sites.

Is it worth paying for a backlink checker?

For occasional checks — auditing your own site a few times a year, sanity-checking a guest post before it goes live — the free tools above cover almost everyone's needs, especially combined with Search Console's uncapped data on your own domain.

It becomes worth paying when you need ongoing tracking: watching a competitor's link growth monthly, auditing dozens of client sites, or exporting full historical link data instead of a capped snapshot. Agencies and anyone doing regular outreach are the main group where a paid plan earns its cost back in saved time.

On accuracy: no backlink checker, free or paid, indexes the entire web, so 'most accurate' depends on what you're checking. Each tool crawls independently and refreshes on its own schedule, which is why the same URL can show different totals in Ahrefs, Moz and Semrush at the same time. The practical fix isn't picking one best tool — it's running the same URL through two of them and treating the overlap as your most reliable signal.
