How to Count the Total Backlinks on Your Site

The short version: there is no single "total backlinks" number because every tool crawls a different slice of the web, so you count by picking one tool as your baseline, checking referring domains rather than raw link count, and tracking the trend over time instead of chasing a perfect figure.

I'll tell you something that annoys me about most backlink guides: they walk you through clicking a button in Ahrefs or Semrush and act like the number that pops up is the truth. It isn't. It's an estimate built from whatever that tool's crawler managed to find that week. Nobody has the full picture, not Google, not Ahrefs, not anyone. So the real skill isn't finding "the" number, it's choosing a consistent method and sticking with it.

Why your backlink count will never be exact

Every SEO tool runs its own crawler, and crawlers have budgets, meaning they can't visit every page on the internet every day. Ahrefs says its crawler visits billions of pages a day, Semrush runs its own index, Moz has Link Explorer, and Google Search Console only shows you links Google itself has indexed and chosen to report. These four sources will give you four different numbers for the exact same website, sometimes wildly different ones.

I've seen domains show 400 backlinks in Search Console and 2,800 in Ahrefs for the same week. That's not a bug. Search Console only reports a sample, prioritises certain links, and updates on its own schedule, which can lag by weeks. Ahrefs and Semrush crawl more aggressively and surface more of the long tail, including spammy directory links Google might not even be counting for ranking purposes. So step one in counting your backlinks is accepting you're measuring an estimate, not a census.

Step-by-step: counting backlinks with free tools

If you don't want to pay for a subscription, Google Search Console is your starting point and it's free if you've verified your site.

• Log into Search Console and go to Links in the left-hand menu.
• Under "External links" you'll see "Top linking sites" and a total count of linking pages.
• Click "More" to export the full list as a spreadsheet.
• Count the rows in the "Target" column against unique domains in the "Linking site" column, because this is where people get confused: total links and total referring domains are not the same thing.

Say you run a small bakery supplies website and Search Console shows 1,200 total links but only 85 referring domains. That means a handful of sites are linking to you many times each, which happens a lot with blog directories, supplier listings, or a press release that got syndicated. Eighty-five real domains talking about your site is a far more useful number than 1,200, because referring domains correlate with ranking strength far more reliably than raw link volume.

Step-by-step: counting backlinks with paid tools

If you've got budget, Ahrefs, Semrush, or Moz give you a fuller picture because their crawlers are more thorough than Search Console's reporting.

• In Ahrefs, go to Site Explorer, enter your domain, and click the "Backlinks" tab. You'll see total backlinks and referring domains as two separate figures at the top.
• In Semrush, use the Backlink Analytics tool and look at the same split: total backlinks versus referring domains.
• Export both the backlinks report and the referring domains report, then cross-check against your Search Console export for overlap.

Here's the uncomfortable bit nobody likes to say out loud: these paid tools also count links that are worthless. A spammy forum signature, a scraped content site that stole your blog post and left your link in, a link farm in a country you've never sold to, all of these get counted in your "total" the same as a link from the BBC or a genuine industry blog. If you're reporting backlink growth to a client or your boss, a rising total can mean your link profile got noisier, not stronger. I'd rather see 40 new referring domains from recognisable sites than 400 new backlinks from directories nobody's heard of.

A worked example to make this concrete

Say you run an online shop selling handmade candles. You check three tools in the same week:

• Google Search Console: 340 total links, 42 referring domains
• Ahrefs: 610 total backlinks, 58 referring domains
• Semrush: 580 total backlinks, 61 referring domains

None of these numbers match, and that's expected. What you'd do next is take the referring domains figure from whichever tool you're using as your ongoing baseline, say Ahrefs, and track that number monthly. If it goes from 58 to 72 over three months, that's real growth you can report with confidence, regardless of what the "total backlinks" figure says. The total backlinks number is noise. The referring domains trend is signal.

How to spot and exclude junk links from your count

Before you report any number, filter out links that shouldn't count toward a healthy total:

• Links from domains with a Domain Rating or Domain Authority under 10, which are often low-quality directories or PBNs.
• Links marked "nofollow" if you're specifically measuring link equity rather than mentions, since nofollow links don't pass the same ranking signal.
• Duplicate links from the same domain pointing to the same page, which Ahrefs and Semrush sometimes count separately if the anchor text differs.
• Links from your own other domains or subdomains, which some tools count as external but which don't carry the same weight as a independent site linking to you.

Run this filter and your "total" will drop, sometimes by 30 or 40 percent. That's fine. A smaller, cleaner number tells you more about your actual authority than a bloated one does.

Setting up ongoing tracking instead of one-off checks

Counting backlinks once a year and treating it as a scorecard is a waste of the exercise. Set up a recurring check:

• Pick one primary tool and commit to it for at least six months so your trend line is consistent.
• Export referring domains monthly, same day each month, into a simple spreadsheet.
• Track new domains gained and lost side by side, because losing links from expired sites or removed guest posts is normal and you want to see both directions.
• Set a rough target, for example gaining 5 to 10 quality referring domains a month if you're actively doing outreach, and measure against that rather than the industry average.

If this feels like more admin than you've got time for, that's a fair reason to bring in outside help rather than a reason to skip it. An AI consultant for small business can set up automated tracking and reporting so you're not manually exporting spreadsheets every month.

Why the number matters less than the trend

I'll say this plainly: if you're obsessing over whether your backlink count is 1,200 or 1,250 this week, you're looking at the wrong thing. Google itself has said publicly that it doesn't use a simple link count as a ranking factor in the way people assume, it's about the quality and relevance of linking domains. So chasing a bigger "total backlinks" figure for its own sake can lead you to buy or beg for links that do nothing for your rankings and might even flag you for a manual action. Count your backlinks to understand direction and quality, not to hit an arbitrary number.

Frequently asked questions

What's the difference between total backlinks and referring domains?

Total backlinks counts every single link pointing to your site, including multiple links from the same domain, while referring domains counts the number of unique websites linking to you. Referring domains is the more meaningful number for judging real authority.

Which tool gives the most accurate backlink count?

None of them is fully accurate because each uses its own crawler with different coverage. Ahrefs and Semrush tend to find more links than Google Search Console, but the best approach is picking one tool and tracking it consistently rather than hunting for a single "correct" figure.

Is Google Search Console enough to count my backlinks for free?

It's a solid free starting point and shows links Google has indexed, but it reports a sample rather than every link and can lag by weeks. For a fuller picture you'd need to supplement it with a paid tool like Ahrefs, Semrush, or Moz.

Should I worry if my backlink total drops?

Not necessarily. Links naturally disappear when sites close, pages get redesigned, or content gets removed. Focus on whether your referring domains trend is growing over months, not whether the raw total ticks down occasionally.
