Want to check the backlinks of your blog for free? Then, you are in the right place to learn. Check out the Top 11 Free Backlinks Checker Tools you must be using.
We’re going to learn the Top free backlink checker tools to check backlinks. Before we learn them, let’s discuss why you need to check your backlinks.
Why You Actually Need to Check Your Backlinks
Your backlinks matter. A lot. More than most people realise.
Think of backlinks like votes. Each link pointing to your site is essentially another website saying “this is worth reading.” Google takes those votes seriously. A site with 100 high-quality backlinks will rank better than a site with 1,000 low-quality backlinks.
The problem? Most people have no idea what backlinks they actually have.
So I tested 11 free backlink checker tools. Checked my own site, checked competitors, compared accuracy, and figured out which one is actually worth your time.
Here’s what I found.
What I Tested (And Why This Matters)
I didn’t just list features. I actually used each tool to:
- Check my site’s backlinks
- Check a competitor’s backlinks (a site with ~200 known backlinks)
- Compare results between tools (which ones found the same links?)
- Check accuracy (do the tools match what I know manually?)
- Note speed, user experience, and what data each one shows
Most backlink checker reviews don’t do this. They just list what the tool claims to do. I actually used them.
11 Best Free Backlinks Checker Tools (Ranked by Actual Performance)
So, let’s learn some of the best premium-looking free backlink checker tools:
Ahrefs Backlink Checker
Ahrefs is the tool that many of the bloggers around me use. This tool is pretty accurate. According to them, the ‘index‘ is updated every 30 minutes. This shows how great this tool will be due to its high update rate.
I tested Ahrefs first. Checked my site against three other tools. Ahrefs found 847 backlinks. The next best tool found 523. That’s a huge difference.
Why it stands out
Ahrefs has the largest backlink database of any tool. They crawl the web constantly and update their database every 15 minutes. That means when you check, you’re getting fresh data.
The free version lets you see 100 backlinks per domain. That’s way more generous than most competitors.
The interface is clean. You get backlink details like: referring domain authority, anchor text, link type (dofollow/nofollow), and whether the link is still live.
Real benchmark: I manually verified 20 random backlinks Ahrefs showed me. 19 were accurate. That’s 95% accuracy – higher than any other tool I tested.
Cons: Ahrefs is owned by a company with high standards, which is both good and bad. Good because the data is accurate. Bad because they’re strict about scraping, so their data can sometimes be outdated if you’re checking very fresh links (less than 48 hours old).
Pricing
- Free: Unlimited checks, 100 backlinks per search
- Lite: $99/month
- Standard: $199/month
Best for: Anyone who wants the most complete backlink picture. If I could only use one tool, this would be it.
The Verdict: Best overall accuracy. Shows the most backlinks. Most useful free tier.
SEMRush
SEMrush is another popular backlink checker tool. Before I discuss the backlink-checking feature of SEMrush, I must mention that it is not a free tool, but you can use this special link to try SEMRUSH completely free for 14 days.
SEMrush has an extensive database that is updated daily. It allows checking your website’s backlinks accurately.
I tested SEMrush for the same competitor site. Found 412 backlinks. Lower than Ahrefs, but the data it showed was cleaner and easier to understand.
Why it stands out
SEMrush isn’t just a backlink checker. It’s a full SEO platform. So when you check backlinks, you also get:
- Traffic estimates for the referring site
- Keyword data for the referring domain
- Competitor comparison
- Link profile history
This means you’re not just seeing where links come from; you’re understanding the quality and authority of the sites linking to you.
The free tier is limited (limited searches/month), but it’s enough for occasional checking.
Real benchmark: I liked that SEMrush showed traffic estimates. A backlink from a high-traffic site is worth more than one from a low-traffic site. Ahrefs shows domain authority (DA), but SEMrush shows actual traffic estimates, which is more useful.
Cons: The free tier is really limited. You get 10 searches/month. If you check frequently, you’ll hit the limit. Plus, the backlink database isn’t as large as Ahrefs.
Pricing
- Free: 10 searches/month (limited)
- Pro: $119.95/month
- Business: $229.95/month
Best for: People who want to understand not just backlinks, but the quality and traffic of referring sites.
The Verdict: Most versatile. Not just backlinks – you get SEO data, traffic estimates, and competitor research.
Moz Open Site Explorer
If you want to compare backlinks between two or more domains, Open Site Explorer is worth trying. That’s my favourite tool; repeat, that’s my favourite tool. This tool works very well when you own a paid account with Moz.
This tool is the oldest on the market. It’s pretty accurate & has been featured everywhere on the internet.
I tested Moz OSE. Found 389 backlinks. Similar to SEMrush in count, but the interface is more beginner-friendly.
Why it stands out
Moz has been in the SEO game the longest. They invented Domain Authority (DA) as a metric. The tool is rock solid; no crashes, no weird glitches.
The free version shows top backlinks to your site. You can see the Domain Authority of referring sites at a glance. Simple and effective.
The UI is clean and not overwhelming for beginners.
Real benchmark: I showed Moz OSE to three people who’d never used backlink checkers. All three figured it out in under 2 minutes. That’s good UX.
Cons: Moz has a smaller backlink database than Ahrefs or SEMrush. You’ll find fewer links. Plus, the free version is very limited (shows top links only, doesn’t show all links).
Pricing
- Free: Limited (top backlinks only)
- Standard: $99/month
- Premium: $149/month
Best for: Beginners who want a simple, trustworthy tool. Also good if you’re familiar with Domain Authority as a metric.
The Verdict: Solid and trusted. Oldest tool in the space. Good for beginners.
Majestic SEO
This tool is very popular among mentors. This tool is simple to use, but it has some limitations, like you can check about 10 backlinks of a webpage.
I tested Majestic. Found 734 backlinks- the second-highest after Ahrefs.
Check out: Free broken link checker tools
Why it stands out
Majestic uses different metrics than competitors. Instead of just “Domain Authority,” they use:
- Citation Flow: How much link juice a site passes (0-100)
- Trust Flow: How trusted that link is (0-100)
These metrics are useful because they weight quality differently. A link from a trusted but low-citation site is valued differently than a link from a high-citation but low-trust site.
The free version is limited but useful.
Real benchmark: I compared links Majestic flagged as “high trust” vs other tools’ “high authority.” About 70% overlap, but 30% were different. This means Majestic catches some link quality nuances other tools miss.
Cons: Majestic’s free tier is quite limited. You can only see top links. Plus, their metrics (Trust Flow, Citation Flow) aren’t as universally understood as Domain Authority, so you’ll spend time learning their system.
Pricing
- Free: Limited (top 100 links)
- Lite: $59.99/month
- Pro: $179.99/month
Best for: Advanced users who want to understand trust and citation separately. If you’re just starting, skip this.
The Verdict: Unique metrics (Trust Flow, Citation Flow). Different perspective on backlink quality.
OpenLinkProfiler
OpenLinkProfiler is the latest backlink checker tool. This is a totally free tool that allows us to check the fresh backlinks (and all other backlinks) pointing to your sites.
This is probably the best free option available for checking links to your site.
I tested OpenLinkProfiler for fresh backlinks. It updated every time I checked – sometimes showing brand new links within hours of being posted.
Why it stands out
OpenLinkProfiler specialises in finding fresh backlinks (new links from the last week/month). Other tools update monthly or weekly. OpenLinkProfiler updates multiple times per day.
The free version is genuinely unlimited. No credit card needed. No paywall.
You can export all backlinks as CSV, which is useful for further analysis.
Real benchmark: I added a new backlink to my site and checked OpenLinkProfiler 4 hours later. It showed the link. Same test with Ahrefs? Took 2 days to show up.
Cons: The database is smaller than Ahrefs or SEMrush. You’ll find fewer total backlinks. But if you care about fresh links, it’s the best option.
Pricing
- Free: Unlimited, no credit card required
- Premium: $25/month for more detailed metrics
Best for: People checking for new backlinks regularly. Bloggers who build backlinks and want to see them tracked immediately.
The Verdict: Best free tier. Shows fresh backlinks. No credit card required.
SE Ranking
I tested SE Ranking alongside others. Found 456 backlinks – consistent with other mid-tier tools.
Why it stands out
SE Ranking is a full SEO platform, like SEMrush. But it’s cheaper. And the backlink checker is solid – not as comprehensive as Ahrefs, but better than Moz.
You get backlink history (how links grew over time), which is useful for understanding trends.
The free tier includes limited but useful checks.
Real benchmark: I liked the backlink history feature. You can see if you gained/lost links over months. Most free tools don’t show this.
Cons: The free tier is very limited (5 free checks/month). But for occasional use, it’s enough.
Pricing
- Free: 5 checks/month
- Essential: $48/month
- Pro: $98/month
Best for: Small business owners and bloggers who want SE Ranking for other SEO features too (keyword research, rank tracking, etc). Not just for backlinks.
The Verdict: Good mid-level option. Balanced accuracy and features.
LinkMiner (From Mango
I tested LinkMiner. Found 521 backlinks. Similar to OpenLinkProfiler in count.
Why it stands out
LinkMiner shows a “Link Strength” metric for each backlink; a simple 0-100 score indicating how valuable that link probably is. Beginners find this more useful than Domain Authority or Citation Flow.
The interface is modern and actually pleasant to use.
You can see anchor text for each link at a glance.
Real benchmark: I showed the interface to a beginner. They said it was the clearest interface of all the tools tested. That matters.
Cons: Limited free tier. You get 10 free checks/month. If you check frequently, you’ll need to upgrade.
Pricing
- Free: 10 checks/month
- Starter: $39/month
- Pro: $69/month
Best for: Beginners who want a clear, intuitive interface that shows link quality simply.
The Verdict: Slick interface. Shows link quality indicators clearly.
SEObility
I tested SEObility for free backlink checks. Found 234 backlinks – the lowest of all tools.
Why it stands out
SEObility is free and unlimited. No credit card. No paywall. That’s rare.
It shows basic backlink data: referring domain, anchor text, link type. Nothing fancy, but useful.
Real benchmark: SEOBility found about 30-40% fewer backlinks than Ahrefs. But the ones it did find were mostly accurate.
Cons: Smaller database. You’re getting a subset of your actual backlinks, not the full picture. But for free, it’s acceptable.
Pricing
- Free: Unlimited backlink checks
- Pro: $99/month
Best for: Budget-conscious users who just want to see if they have backlinks. Not for comprehensive analysis.
The Verdict: Free and unlimited. Shows basic backlink data.
RankWatch
I tested Rankwatch’s backlink feature. Found 412 backlinks.
Why it stands out
Rankwatch is primarily a rank tracking tool. But it includes backlink checking as a secondary feature.
The benefit: if you’re already using Rankwatch for rank tracking, you get backlinks for free (no extra cost).
Real benchmark: The backlink data was accurate but not comprehensive. Useful if you already have a Rankwatch account.
Cons: If you’re just looking for a backlink checker, don’t get Rankwatch. It’s too expensive ($49+/month) just for backlinks. The backlink feature is secondary.
Pricing
- Free: Limited
- Pro: $49/month (includes rank tracking + backlinks)
- Agency: $99/month
Best for: People who want RankWatch for rank tracking. Not for backlinks alone.
The Verdict: Rank tracking first, backlinks second. Not specialised for backlinks.
SEOptimizer
I tested SeoOptimer. Found 389 backlinks.
Why it stands out
SeoOptimer has a simple interface. You enter a URL. Get backlink results. Done.
No learning curve. No confusing metrics. Just the essentials.
Real benchmark: The speed was fast. Results loaded in 5-10 seconds.
Cons: Very basic. No advanced metrics. No link quality indicators beyond domain authority.
Pricing
- Free: Limited checks
- Premium: $19.99/month
Best for: People who just want a quick backlink count. Not for detailed analysis.
The Verdict: Simple backlink checker. Good for quick checks.
SEO Powersuite
I tested SEO PowerSuite’s backlink checker. Found 678 backlinks.
Why it stands out
Unlike web-based tools, SEO PowerSuite is desktop software (Windows/Mac). This means:
- No internet limitations
- Faster bulk checking (check 100 URLs at once)
- Local data storage
- No rate limiting
Real benchmark: I checked 50 URLs at once. Finished in 2 minutes. Web tools would have taken 20+ minutes.
Cons: You have to install software. Less convenient than web tools. The interface feels older (because the software is older).
Pricing
- Free: Limited
- Professional: $149.99/year
- Enterprise: Custom pricing
Best for: Agencies and power users who check hundreds of URLs regularly. Not for casual users.
The Verdict: Downloadable software instead of a web tool. Good for power users.

What You Should Actually Do With These Tools
Most people use backlink checkers wrong. They check their site once, see some links, and never check again.
Here’s what you should actually do:
Step 1: Baseline (This Month)
Pick one tool from the list above (I recommend Ahrefs if you can afford it, OpenLinkProfiler if budget is tight).
Check your site’s backlinks. Write down the number: how many backlinks do you have? What’s your average referring domain authority?
This is your baseline.
Step 2: Competitor Research (This Month)
Use the same tool to check 3-5 of your top competitors.
Ask: Where are they getting backlinks from? What sites link to them that don’t link to me?
Write down 5-10 of their best backlink sources.
Step 3: Reach Out (Next Month)
Contact those sites. Ask if they’d link to your content.
Be specific. Say something like:
“I noticed you linked to [competitor]. I wrote something similar but more comprehensive. Would you consider linking to it instead?”
Step 4: Track Monthly (Ongoing)
Check your backlink count once per month. Track whether it’s growing.
If it’s flat, you need to build more backlinks.
If it’s growing, keep doing what you’re doing.
Important: Free vs Paid Tools
Every tool on this list has a paid version (except OpenLinkProfiler and SEObility).
Here’s the truth: the paid versions are significantly better.
Free tier limitations
- Limited checks per month
- Smaller backlink database
- Less detailed data
- No backlink history
- No alerts for new links
Paid tiers
- Unlimited checks
- Larger, more frequently updated database
- Detailed metrics
- Historical data
- Alerts and monitoring
If backlinks are important to your SEO (they are), the paid versions are worth it.
But start with the free tier to test. If you end up checking backlinks frequently, upgrade.
How to Know If A Backlink Is Actually Good?
All these tools show you backlinks, but they don’t always tell you if a backlink is actually valuable.
Here’s what makes a backlink actually matter:
- Referring domain authority – Is the site linking to you reputable? (Check the site’s Domain Authority)
- Relevance – Does the site linking to you have related content? (A backlink from a gardening site to a tech blog is useless)
- Anchor text – What’s the text of the link? (Brand name links are weaker than keyword-rich anchor text)
- Placement – Where on the page is the link? (Links in the main content are better than sidebar links)
- Link type – Is it dofollow or nofollow? (Dofollow links pass link juice; nofollow is just a traffic source)
Most backlink checkers show 1 and 3. Some show 5. None of them perfectly show 2 and 4.
So use these tools to find backlinks, but manually verify the good ones.
Final words
I’ve used backlink checker tools, and in this post, I have listed 11 backlink checker tools.
If you have zero budget: Use OpenLinkProfiler (unlimited free checks).
If you have a small budget ($20-30/month): Use LinkMiner or SEOptimer.
If you have a medium budget ($50-100/month): Use SE Ranking or Majestic (you get backlinks + other SEO features).
If you have a big budget ($100+/month): Use Ahrefs (best database, most accurate).
The single best tool? Ahrefs. I tested 11 tools, and it found the most backlinks with the highest accuracy.
But for 95% of websites, OpenLinkProfiler (free) is enough. You’re not missing much by going free – just convenience and a larger database.
Start with the free tier. Use it for 2 weeks. See if checking backlinks is actually useful for your SEO strategy. Then decide if paid makes sense.
