A backlink checker is a tool that crawls the web and lists the links pointing at a website, and no single free one shows you every backlink you've got. For your own site, start with Google Search Console's Links report and Ahrefs Webmaster Tools, which are both free; for someone else's site you need a checker that doesn't ask you to verify ownership.
The detail matters, because the number you see depends entirely on where you look, and the free sources each hide a limit in the small print. Below I've put those limits side by side, explained why two tools never agree, and grouped every backlink guide on this site by the question you're trying to answer.
How many backlinks does my site have? The honest answer
Nobody can give you an exact figure, Google included. Google's own help page for the Links report says it "isn't a comprehensive list of every link on your site". It shows a sample of internal and external links, it limits its tables to 1,000 rows, and it may still list links that have since been removed.
So treat the Google number as a floor, not a total. Every other checker gives you an estimate built from its own crawl. The useful question isn't "what's my exact count?" but "which sites link to me, and are they the ones that matter?"
Where to look, and what each source shows
Here's what each of the common free or free-to-try sources says about itself, as of Nov 2026. I've only included limits the vendors state on their own pages.
| Source | Free? | What it shows | The catch |
|---|---|---|---|
| Google Search Console, Links report | Yes, for sites you've verified | External links (top linked pages, top linking sites, top linking text) and internal links | A sample, not a comprehensive list; tables capped at 1,000 rows; may include removed links; doesn't say whether a link is nofollow |
| Ahrefs Webmaster Tools | Yes, for verified websites | Site Explorer shows up to 1,000 backlinks at once; Site Audit gives 5,000 crawl credits per verified project per month | You have to verify the site, so it only works for sites you own |
| Ahrefs free Backlink Checker | Yes, a free page | Describes itself as a glimpse into the power of the premium tool, and mentions referring domains, backlinks, Domain Rating and Ahrefs Rank | The page doesn't state its limits; DR and UR in the browser extension need a free Ahrefs account |
| Semrush | A free plan at $0 with no card, and a seven-day trial of paid plans (dollars as shown on the page, as of Nov 2026) | A free plan, and a trial of the paid plans | The prices page I checked didn't confirm which plan includes backlink data, so check before you rely on it |
| SE Ranking | A 14-day free trial, no credit card (as of Nov 2026) | A trial of the paid plans | It's a trial, not a free plan, and I haven't verified its backlink limits |
The pattern is easy to miss. Both of the forever-free options, Search Console and Ahrefs Webmaster Tools, only work on sites you can prove you own. That's fine for checking yourself. It's useless for looking at a competitor, which is where most people want to start.
Why two tools give you two different numbers
Run your site through two checkers and you'll get two counts, sometimes wildly different ones. My plain advice: don't try to reconcile them. Each tool runs its own crawler and keeps its own index, so each one has seen a different slice of the web at a different time.
Google adds two quirks of its own. Its Links report groups linking domains by root domain, so a dozen subdomains of one site can show up as a single linking site. And it doesn't tell you whether a link is nofollow, so its count mixes links that pass value with links that don't. If you want the longer breakdown of what a checker's numbers mean and where they mislead you, I've written it up in what a backlink checker really shows you.
The free route, in order
If you don't want to pay anything, this is the order I'd work in. I've kept it to the decisions; the click-by-click Search Console steps live in my free Search Console backlink walkthrough.
- Open the Links report in Search Console and look at Top linking sites. That's your floor, straight from Google.
- Remember the cap: a table that stops at 1,000 rows is the report's limit, not the end of your links.
- Verify the same site in Ahrefs Webmaster Tools and open Site Explorer, which shows up to 1,000 backlinks at once from Ahrefs' own index.
- Compare the two lists. Sites that appear in both are your solid core; sites in only one are worth a quick look by hand.
- For a competitor, use a checker that doesn't need verification: the free Ahrefs page for a glimpse, or a paid tool's trial for the full list.
- Note the date and the count somewhere simple, so next month you're comparing like with like rather than starting again.
Checking a competitor's backlinks
This is where the free route runs thin. Search Console and Ahrefs Webmaster Tools both need you to verify the site, so neither will show you a rival's links. You're left with three choices: Google search operators, which are free and slow; a free checker page, which gives you a sample; or a trial of a paid suite, which opens up the paid tool for the length of the trial.
If you go the trial route, plan the work before you start the clock. Semrush's trial runs for seven days and SE Ranking's for 14, as of Nov 2026, so have your competitor list ready on day one. I've written up three ways to do it: the free Google search method, spying on a competitor's backlink profile with the tools I use for clients, and a step-by-step backlink search for one competitor.

Quality matters more than the count
The count is what people ask for, and it tells you least. One link from a site your customers read will do more for you than a pile of links from pages nobody visits. That's why I'd rather you spend ten minutes looking at who links to you than an hour chasing a bigger total.
If you're weighing up a link before you pay for it, use the checks I run on every backlink before buying it. If something looks off in your own profile, start with how to spot which backlinks are hurting your site before you even think about disavowing anything yourself.

My verdict
I'd start with Search Console, add Ahrefs Webmaster Tools for your own site, and skip paying for a link tool until you know which links you need to track. When you do need a competitor's full profile, take a trial with a plan already written, so you aren't paying for a month to use it for an afternoon. And whatever number you end up with, don't chase it. Look at who's linking to you, and go after more of that kind.

Frequently asked questions
How can I check how many backlinks my site has for free?
Use the Links report in Google Search Console, then verify your site in Ahrefs Webmaster Tools, which shows up to 1,000 backlinks at once. Neither gives a complete count, so treat the higher, overlapping picture as your estimate.
Is Google Search Console's backlink count accurate?
It's a sample. Google says the Links report isn't a comprehensive list, limits tables to 1,000 rows and may include links that have since been removed. It's a reliable floor, not a total.
Can I check a competitor's backlinks for free?
Not with Search Console or Ahrefs Webmaster Tools, which both need you to verify the site. Use Google search operators, a free checker page such as Ahrefs' Backlink Checker, or a paid tool's trial.
Why do backlink checkers show different numbers?
Each one runs its own crawler and keeps its own index, so each has seen a different part of the web. Google also groups linking domains by root domain, which changes the count again.
Does Search Console show nofollow links?
It doesn't tell you whether a link is nofollow, according to Google's help page for the Links report, so its counts mix followed and nofollow links.
