Inbound Links Checker Free | Check Your Backlinks Instantly

Written by Mehar Ali Hassan | 9/23/2026

Most site owners find out about a lost backlink months after it happened. By then the traffic drop already showed up in the analytics report and nobody could figure out why. A free inbound links checker fixes that blind spot. It shows you who is linking to your site right now, which links have gone dead and where your link building actually needs attention instead of guessing.

What Is an Inbound Links Checker?

  • An inbound links checker scans external sites linking to your domain and shows referring domains, anchor text and link status so you know who is sending traffic and authority your way. It pulls this from a crawler database rather than checking your site in real time.

  • The term inbound links gets used alongside backlinks pretty much everywhere, and for good reason they mean the same thing. A link checker looks outward, not inward, so it is different from an internal link audit which checks how pages on your own site connect to each other.

  • A lot of site owners confuse the two tools. One client we audited had never run an inbound check in three years. They had picked up over forty new referring domains they didn't even know about and lost about a dozen from old directory listings that had gone offline.

Why Backlinks Matter for SEO Rankings

Backlinks act as votes of trust. Search engines use them to judge authority, so pages with quality referring domains tend to rank higher and pull more organic traffic over time.

Google has said for years that links remain one of the top ranking signals, and nothing in recent algorithm updates has really changed that. What has changed is quality over quantity. A single link from a relevant, trusted site now carries more weight than a dozen from low quality directories.

Three things links help with:

  • Search engine rankings, since pages with strong referring domains get crawled and trusted faster

  • Referral traffic, meaning real visitors who click through from another site

  • Faster discovery, since a crawler finds new pages quicker when they are linked from an already indexed site

How to Check Your Backlinks Free (Step by Step)

Enter your domain into a free backlink checker, review the referring domain list, filter by follow or nofollow, then export results to track new and lost links every month.

Here's the process most agencies follow, whether you're doing it with a free tool or a paid one.

  1. Open the checker and enter your full domain including https

  2. Let the crawler pull its stored backlink data, this can take a few seconds depending on domain size

  3. Sort results by referring domain rather than raw link count, since one domain can send ten links that count as one relationship

  4. Filter for nofollow versus follow links to see what is actually passing authority

  5. Export or screenshot the list so you have a baseline to compare against next month

What Results Actually Show You

A decent free tool to check backlinks will list the linking page, the target page on your site, the anchor text used and whether the link is follow or nofollow. Some also flag whether the link is still live or has gone to a 404.

If you want the full picture of your site's SEO health beyond just links, our seo audit checker covers the technical side too, so you're not just staring at a backlink table with no context.

Key Backlink Metrics to Track

Domain Authority, Page Authority, referring domains and anchor text distribution are core metrics. They signal link strength, relevance and risk across your entire backlink profile.

Domain Authority and Page Authority

Moz page authority and domain authority scores were built as a way to estimate how likely a page or site is to rank, on a scale that usually runs from one to one hundred. They're not a Google ranking factor themselves, they're an industry estimate, but most agencies still use them as a quick health check.

A score above 40 generally signals a site with decent link trust behind it. Below 20 usually means the site is new or has very few quality links pointing to it.

Referring Domains and Anchor Text

  • Quality Over Quantity: Referring domain count matters more than total backlink count. For example, ten links coming from a single blog count as just one relationship, whereas ten links from ten distinct websites represent ten separate votes of trust that carry significantly more weight.

  • Core Backlink Metrics to Track:

    1. Domain Authority: Overall link trust estimate (a score of 30 and above is ideal for most niches).

    2. Referring Domains: Number of unique linking sites (aim for higher relative to competitors).

    3. Anchor Text Mix: Shows how natural your link profile looks (should be mostly branded or naked URLs, not exact-match keywords).

    4. Follow vs. Nofollow: Indicates how much authority passes through (a healthy mix is recommended, not 100 percent nofollow).

Backlink Profile and Link Building Basics

A backlink profile is your full inventory of inbound links. Link building is the active process of earning new ones through outreach, guest posts and digital PR.

People treat these as the same thing and they're not. Your profile is a snapshot, a picture of where you stand today. Link building is the ongoing work that changes that picture over time.

Common link building efforts include:

  • Guest posting on sites your audience already reads

  • Digital PR, meaning getting mentioned in news coverage or industry roundups

  • Reclaiming unlinked brand mentions, where a site named your brand but never linked it

  • Resource page outreach, where you pitch your page as a genuinely useful addition

If your content itself isn't structured well enough to earn links naturally, that's usually a content gap problem before it's a link building problem. Our keyword clustering tool helps you group topics so your pages actually have something worth linking to in the first place.

Broken Link Checker: Fix 404s and Lost Backlinks

A broken link checker flags 404 errors from dead pages, letting you redirect or reclaim lost link equity before it drags down crawl efficiency and rankings.

This is the part most backlink articles skip entirely. You can have a great backlink profile and still be leaking value because pages that used to hold those links got deleted, moved or renamed without a redirect.

Internal Versus External Broken Links

Internal broken links point to a page on your own site that no longer exists. External broken links, sometimes called outbound links, point off your site to a page that has since gone down or moved.

Both hurt you but in different ways. Internal ones waste crawl budget and confuse visitors navigating your site. External ones make your content look outdated, since you're sending readers to a dead end.

Fixing a broken backlink usually goes like this:

  1. Run a broken link checker to find every 404 on your site

  2. Cross reference which of those broken pages still have backlinks pointing to them

  3. Set up a 301 redirect to the closest matching live page, not a blanket redirect to your homepage

  4. Recheck the fix a week later to confirm the redirect actually resolved

We've seen agencies redirect every broken URL straight to the homepage as a shortcut. It works in the sense that the 404 goes away, but it wastes the specific relevance that backlink was pointing at. Redirecting a broken article link to your homepage instead of a related article throws away most of the value that link had.

You can run this check directly with our broken link checker, and pair it with the internal link finder tool to catch internal 404s at the same time.

Free Backlink Checker vs Ahrefs Semrush and Moz

  • Core Difference: Free checkers give a quick backlink snapshot, whereas premium tools like Ahrefs, Semrush, and Moz add deeper historical data, competitor gap analysis, and toxic link scoring at a monthly cost.

  • Which Tool Fits Your Needs:

    • Free Backlink Checker: Costs nothing and provides a current snapshot; best suited for quick checks and small sites.

    • Ahrefs Backlink Checker: Paid (with a limited free trial) with a deep historical database; best for agencies and larger sites.

    • Semrush: Paid (with a limited free trial) with strong competitor gap tracking; ideal for combined SEO and PPC teams.

    • Moz Link Explorer: Paid (with a trial of Moz Pro available) featuring long-running authority metrics; best for teams already using Moz metrics.

  • Important Limitation to Consider: Free tools often show data with a 7 to 30-day lag compared to paid tools that crawl daily. If you need same-day link discovery, that lag matters, but for standard monthly check-ins, it won't impact your workflow.

Competitor Backlink Analysis

Competitor backlink analysis means checking rival domains referring links, spotting gaps, then pitching those same sites for your own placements to close the authority gap.

This works because sites that already linked to a competitor in your space are clearly open to linking to businesses like yours. You're not cold pitching a total stranger, you're pitching someone who already proved they'll link to your type of content.

  1. Run a backlink checker on two or three direct competitors

  2. Filter for referring domains that don't already link to you

  3. Sort by domain authority to prioritize the strongest opportunities first

  4. Check what kind of content earned that link, an article, a tool, a data page

  5. Pitch a similar or better version of that content to the same site

The gap here isn't finding the list, most tools can do that. The gap is what you do with it. A lot of teams pull the list and never follow up, which makes the whole exercise pointless.

Spammy Links and Google's Disavow Tool

Spammy links from low quality or irrelevant domains can trigger ranking penalties. Google's Disavow Tool lets you tell Search Console to ignore those toxic backlinks.

Not every weird looking link needs action. Google has gotten better at ignoring obvious spam on its own. Disavowing should be reserved for cases where you can see a clear pattern, like a sudden spike from a paid link scheme you didn't authorize, or leftover links from a low quality SEO vendor you used years ago.

Signs a link might be worth disavowing:

  • It comes from a site in an unrelated language or industry with no logical reason to link to you

  • The anchor text is an exact match keyword stuffed unnaturally

  • A large batch of links appeared on the same day from newly registered domains

We handled a case where a client's previous agency had bought links from a private blog network. The pattern was obvious once we pulled the list, dozens of low authority sites all created within the same month, all linking with the exact same anchor text. Disavowing the domains, not the individual URLs, cleared it up within a couple of months.

If your backlink situation needs more than a self check, our SEO services team handles full profile audits including disavow file preparation.

Frequently Asked Questions

What is a free inbound links checker exactly?

It's a tool that scans a crawler's stored database of web pages and shows you every external site currently linking to your domain, along with details like anchor text and whether the link is follow or nofollow. Free versions usually limit how many results you can view or how often you can refresh the data.

How many backlinks should a website have?

There's no fixed number. A small local business site might rank fine with twenty strong referring domains, while a competitive national market could need hundreds. What matters more than the count is the relevance and authority of the domains linking to you.

Do nofollow backlinks still help rankings?

They don't pass direct ranking authority the way follow links do, but they still bring referral traffic and can contribute to a natural looking link profile. A site with only follow links actually looks suspicious to search engines.

How often should I check my backlink profile?

Monthly is a reasonable baseline for most small to medium sites. If you're actively running link building campaigns or you've had a recent ranking drop, checking weekly makes more sense until things stabilize.

What's the difference between backlinks and internal links?

Backlinks come from other websites linking to yours. Internal links connect pages within your own site to each other. Both matter for SEO but they're checked with different tools and serve different purposes.

Can broken backlinks hurt my SEO?

Yes. A backlink pointing to a page that now returns a 404 wastes the link equity that page would have received, and it creates a poor experience for anyone who clicks through expecting real content.

How do I find who is linking to my competitor?

Run their domain through a backlink checker the same way you would your own. Filter the results for referring domains, then compare that list against your own backlink profile to see the gaps.

Is Google's Disavow Tool safe to use?

It's safe when used carefully on a clear pattern of spammy or toxic links. Using it too broadly, or disavowing links that were actually fine, can remove authority you didn't need to lose. It's best treated as a targeted fix, not a routine cleanup step.

What's a good Domain Authority score for a new site?

New sites typically start near zero and climb as they earn links naturally. Anything in the teens or twenties within the first year is a reasonable trajectory for a small business site building links consistently.

Can I check backlinks of any website, not just mine?

Yes, most backlink checkers work the same way for any public domain, which is exactly what makes competitor backlink analysis possible in the first place.
