Backlinks Checken: The Direct Answer 2026

The short version: to check backlinks, start with Google Search Console because it's free and it's your own data, then cross-check with one paid tool like Ahrefs, Semrush or Moz because no single source sees every link on the internet. Look at referring domains, not total backlink count, because one site linking to you fifty times from its footer is not fifty opportunities, it's one.

What "checking your backlinks" means

People say "check my backlinks" and mean three different things: how many links do I have, are they any good, and has anyone built new ones recently. Those are three separate jobs. Conflating them is why so many business owners end up staring at a number that doesn't tell them anything useful.

A backlink is simply another website linking to yours. Google (and Bing, though let's be honest, almost nobody optimises for Bing on purpose) uses those links as a trust signal. More links from relevant, established sites generally means more trust. But "more" is doing a lot of work in that sentence, and that's where most of the confusion starts.

Step one: use Google Search Console first, not a paid tool

This is the bit most backlink guides skip because it's not exciting and it doesn't sell a subscription. Google Search Console is free, it's Google's own data, and it's the only source that tells you exactly what Google itself sees pointing at your site.

• Log into Search Console for your property
• Go to Links in the left menu
• Click "Top linking sites" under the External links panel
• Export the list and sort by domain, not by number of links

This gives you a baseline. It's not complete and it updates slowly, sometimes weeks behind reality, but it's free and it's accurate for what it does show.

Step two: cross-check with a paid crawler

Search Console only shows links Google has already crawled and decided to report. It won't show you everything, and it's not built for competitor research. For a fuller picture you need a tool that crawls the web independently: Ahrefs, Semrush, or Moz's Link Explorer are the three most used. There's also Ubersuggest if budget is tight, though its index is smaller.

Here's the uncomfortable bit nobody likes admitting: these tools will all give you different numbers for the same site, sometimes wildly different. Ahrefs might show 1,200 referring domains for a site, Semrush might show 850, Moz might show 600. None of them is "wrong". They each crawl a different slice of the web with different frequency and different sized indexes. If you've ever panicked because one tool showed a drop and another showed growth, that's why. Pick one tool as your main source of truth and stick with it for trend tracking, and only use a second tool for occasional cross-checks, not daily comparisons.

A worked example: the plant shop with 4,000 backlinks

Say you run an online plant shop and you check your backlinks in Ahrefs. It says you have 4,000 backlinks. Sounds brilliant. Then you check referring domains and it says 60. That means those 4,000 links are coming from only 60 actual websites, probably because a handful of directory sites link to every product page on your site, or because one blog post of yours got embedded on 30 different low quality scraper sites that copy content automatically.

Sixty real, relevant websites linking to a plant shop is a reasonable number for a small ecommerce brand. Four thousand backlinks sounds impressive on a slide deck but means almost nothing on its own. If you'd stopped at the headline number, you'd have told yourself the SEO work was going brilliantly when it needed more outreach to new, different domains, not more pages crawled on the same 60 sites.

Step three: separate the good links from the junk

Once you've got your list of referring domains, the real work starts. For each one, ask:

• Is this site about something even loosely related to my industry?
• Does the site look like it has real content, or is it clearly built just to sell links?
• Is the link in the main body text, or shoved in a sidebar or footer stuffed with 200 other links?
• Does the domain have its own organic traffic, or is it a ghost site?

Most backlink tools will show a "domain rating" or "domain authority" score, somewhere from 0 to 100. As a rough working rule, anything under 10 from a site with no real traffic and no relevance to your industry is dead weight at best, and a disavow candidate at worst if it looks like a link farm. Anything above 30 from a relevant site is worth protecting and, if you can, getting more of.

Step four: check new links on a schedule, not constantly

Checking backlinks daily is a waste of your time. Link profiles move slowly. A sensible cadence is monthly for most small businesses, weekly if you're actively running a PR or guest post campaign and want to confirm links went live. Set a recurring reminder, export the referring domains list, and compare it against last month's export in a simple spreadsheet. New additions and any that dropped off are the only two columns that matter.

What to do with what you find

Checking is only half the job. The data is useless if nothing changes afterwards.

• If you've got a handful of high quality links from relevant sites, work out how you got them and repeat the method, whether that was a guest post, a quote for a journalist, or a product review
• If you've got a pile of spammy links from obvious link farms or gambling-adjacent sites you never built, use Google's disavow tool as a last resort, not a first step
• If your referring domain count hasn't moved in six months, that's a sign your content isn't giving anyone a reason to link to it, not a sign your checking tool is broken
• If a competitor's referring domain count is climbing fast, check which sites are linking to them that aren't linking to you, that list is your outreach target list

A quick word on free backlink checkers

Free tools like Ubersuggest's limited checker, or the free tiers inside Ahrefs and Moz, will show you a capped number, often the top 100 links only. That's fine for a quick sanity check on a small site but useless for anything with real scale or for real competitor comparison. Treat free results as a taster, not a dataset you build decisions on.

Frequently asked questions

How many backlinks do I need for good SEO?

There's no fixed number. What matters more than quantity is the number of unique, relevant referring domains and how trustworthy they are. A small local business might do well with 30 to 50 solid referring domains, while a national ecommerce brand competing on broad terms might need several hundred. Compare your referring domain count to two or three direct competitors rather than chasing an arbitrary industry figure.

Why do different backlink checkers show different numbers?

Each tool, including Ahrefs, Semrush and Moz, crawls the web independently with its own index size and update frequency, so none of them sees every link that exists. Pick one tool as your primary source for tracking trends over time and treat the others as occasional cross-checks rather than expecting matching numbers.

Is Google Search Console enough to check my backlinks?

Search Console is a strong free starting point because it shows Google's own view of your links, but it updates slowly and doesn't support competitor research, so most businesses pair it with a paid tool like Ahrefs or Semrush for a fuller and faster picture.

Should I disavow bad backlinks straight away?

No, disavowing should be a last resort used only when you've identified clearly spammy or manipulative links you didn't build yourself and can't get removed by contacting the site owner. Using the disavow tool on links that are merely low quality rather than harmful can do more damage than leaving them alone.
