A few free backlink monitoring tools works amazingly. This guide breaks all of that down including detailed features, honest pros and cons, pricing, and a comparison table.

What is the Role of Backlinks on Your Website? 

Websites are truly incomplete without backlinks, as they help gain credibility and authority. When highly-ranked websites link back to your web pages or content, search engines see this activity as a confirmation of its worthiness. This boosts your website in search rankings while also generating a natural traffic. Backlinks are very important in enhancing your SEO and increasing visibility across the internet. 

Why Backlink Checking Tools are a Necessity? 

It is about time to have backlink checking tools by your side for your website’s well-being. The tools work as a link analyzer and are used to identify spam or poor-quality links, track new backlinks, and even analyze the competitor’s strategy.

Backlink checker tools also help you build a habit of regular checks that ensure your website has a clean backlink profile and eventually contribute to effective SEO and enhanced search engine rankings.

When you are actively building backlinks, the real challenge, however, isn’t acquiring them, but ensuring that they are live. This is where the backlink monitoring tool from Link Publishers can actually be useful.

Instead of juggling multiple tools for checking links, fixing issues, and analyzing performance, monitoring is available in one place. It’s designed for people who want a simple way to keep their backlink profile clean without overcomplicating the process.

What makes this backlink monitoring tool really useful, however, is the simplicity of its interface. You don’t have to be an expert in SEO to understand exactly what’s going on with your backlinks.

If you are tired of constantly monitoring whether your backlinks are live or not, then this tool can be really useful for you, as it does that for you and gives you a comprehensive view of everything that’s going on with your backlinks.

2. Ahrefs – Best for In-Depth Backlink Analysis

Ahrefs started purely as a backlink analysis tool back in 2010, and that DNA still shows. The crawler runs 24/7, refreshing data every 15 to 30 minutes. You’ll notice the difference compared to tools that update weekly.

The database holds 35+ trillion external backlinks, and the competitor research features are genuinely hard to beat. Link Intersect 2.0 alone has probably saved hours of manual prospecting for a lot of teams.

Key Features

• Backlink monitoring and analysis with 35+ trillion links in the index
• Referring domain tracking across any domain or URL
• Anchor text analysis to spot over-optimized or manipulative patterns
• Competitor backlink research via Site Explorer and Link Intersect 2.0

Pricing

Free backlink checker available with no account required. Paid plans start at $108/month billed annually for the Lite plan. Standard, Advanced, and Enterprise tiers add historical data, higher usage limits, and more seats.

3. SEMrush – Best All-in-One SEO Backlink Checker

SEMrush has grown well beyond keyword research at this point. As a competitor backlink checker and full SEO platform, it now holds 43+ trillion links from 390 million referring domains. That’s the largest raw backlink count of any tool in 2026. 

But the more interesting part is what it does with that data. The Backlink Gap tool lets you compare up to five competitors side by side. And the toxic link detection combined with Google Search Console integration makes the disavow process considerably less time-consuming  than doing it manually.

One thing worth mentioning: Semrush One now tracks your visibility across ChatGPT, Perplexity, and Google Gemini alongside traditional search. If you’re paying attention to how AI search is changing SEO, that’s a genuinely useful addition.

Key Features

• 43+ trillion backlinks in the index, refreshed every 15 minutes
• Backlink Analytics for full domain-level analysis

• Toxic link detection and audit workflow is the best of any tool
• Genuinely replaces multiple standalone SEO tools
• AI search visibility tracking is something competitors don’t offer yet

Cons

• Starting price is higher than most alternatives. Pro plan is nearly $140/month
• Feature breadth can be overwhelming if you just want backlink data
• Additional user seats add up fast for larger teams

Pricing

Free plan available with limited daily queries. Paid plans: Pro at $139.95/month, Guru at $249.95/month (popular with agencies), Business at $499.95/month for larger teams.

4. Moz Link Explorer – Best for Beginners and Small Businesses

Since 2004 Moz Link checker tool has been around, and the Domain Authority metric it popularized is still one of the most referenced numbers in SEO. This tool is the most approachable competitor backlink analysis option if you’re just getting started and don’t want to feel lost from day one.

The database is technically the largest by index count at 44.8+ trillion links, which sounds impressive. In practice though, the daily query limits are much lower than Ahrefs or SEMrush. Still, for a small business owner monitoring their own site and doing occasional competitor checks, it covers what you need.

Key Features

• 44.8+ trillion backlinks indexed (largest by count)
• Domain Authority (DA) and Page Authority (PA) metrics
• Spam Score for flagging potentially harmful links

Pricing

Free plan with 10 queries/month. Paid plans start at $49/month for the Starter plan (one user, one domain). Agency/Large plan starts at $299/month for up to 3 users.

5. SE Ranking – Best for Agencies and Freelancers

SE Ranking doesn’t have the same name recognition as the tools above, but it’s been gaining ground fast. The backlink index sits at 3+ trillion links and has been growing quickly. 

In some tests, it actually surfaces more referring domains than tools with nominally larger databases. The white-label reporting is built in natively, which makes a real difference when you’re sending client reports every month.

Pricing is structured around projects and keywords rather than flat tiers, so it tends to work out cheaper for agencies managing multiple clients. The 14-day free trial doesn’t require a credit card.

Key Features

• 3T+ backlinks in the index, growing rapidly
• Backlink analysis with referring domain and anchor text tracking
• Competitor backlink research and backlink gap analysis
• New and lost link monitoring with regular alerts
• White-label reporting built in natively

Pricing

Plans start from $52/month. 14-day free trial available. Scales based on number of projects and keywords tracked.

6. Majestic SEO – Best for Trust Flow and Citation Flow Metrics

Majestic has been doing this since 2008. The main reason people use it is Trust Flow and Citation Flow. These proprietary metrics that measure link quality based on proximity to trusted, authoritative seed sites. If you’ve ever looked at a link from a site that seems fine on the surface but something feels off, Trust Flow often catches what other metrics miss.

Topical Trust Flow adds another layer. It categorizes linking domains by niche relevance, which is genuinely useful when you’re vetting a link prospect and want to know whether the site’s audience actually overlaps with yours. 

The interface, though, looks like it hasn’t had a major design update in a while. And compared to Ahrefs or SEMrush, the feature set is narrow. It’s a specialist backlink audit tool for SEO, not a full platform.

Key Features

• Trust Flow (TF) and Citation Flow (CF) proprietary quality metrics
• 14+ trillion backlinks across Historic and Fresh indexes
• Referring domain and anchor text analysis
• Topical Trust Flow — categorizes linking domains by niche relevance
• Bulk backlink checker for analyzing multiple URLs at once
• Link context analysis showing surrounding content
• Backlink history charts for tracking link growth over time
• Competitor backlink research via Site Explorer

Pros

• Trust Flow metric adds a unique angle on link quality
• Topical Trust Flow is excellent for niche relevance analysis
• Affordable entry point for specialist analysis

Cons

• Index is smaller than Ahrefs and SEMrush
• Interface feels dated compared to modern tools
• Not a full-suite platform. Keyword research and rank tracking are limited

Pricing

Lite plan at $49.99/month. Pro plan at $99.99/month. API access available on higher plans.

7. BuzzSumo – Best for Content-Driven Link Research

BuzzSumo comes at backlinks from a completely different angle than the other tools here. Rather than starting with “who links to this domain,” it starts with “what content earns links in this space.” 

That makes it a natural fit for content marketing teams and PR people who want to connect their editorial strategy with actual link acquisition outcomes.

The backlink data itself is more limited than a specialist tool, and at $199/month it’s on the expensive side if link analysis is your main goal. Most teams who use BuzzSumo use it alongside Ahrefs or SEMrush rather than instead of them. 

But if you’ve ever spent time trying to figure out what to write that will actually earn links, BuzzSumo’s content performance data makes that question much easier to answer.

Key Features

• Backlink analysis tied directly to content performance metrics
• Referring domain tracking and backlink monitoring
• Content discovery — find the most shared and linked-to content in any niche
• Competitor backlink research through content analysis
• Brand mention monitoring with backlink context
• Influencer identification for outreach
• Social share data alongside backlink metrics
• Alerts for new backlinks to specific pages or domains

Pros

• Unique combination of content performance data and backlink tracking
• Excellent for content marketers who want to connect strategy to link outcomes
• Makes it easy to spot what content earns links in a given niche

Cons

• Not a dedicated backlink analysis tool. Link data is more limited
• Expensive relative to what you get for pure link research
• Best used as a complement to Ahrefs or SEMrush, not a replacement

Pricing

No free plan. Paid plans start at $199/month. Content Suite plan at $299/month includes more advanced content research features.

8. Google Search Console

Google Search Console is the most accurate free backlink monitoring tool available. It shows every external link pointing to your verified domain exactly as Google sees it, including top linking sites, top linked pages, and most common anchor texts. And it’s completely free for verified site owners.

• Top linking domains and top linked pages breakdown
• Anchor text analysis
• Completely free for verified site owners
• Integrates with Google Analytics and Google Ads

Limitation: Only works for your own verified domain. You can’t use it to check competitor backlinks.

9. OpenLinkProfiler

OpenLinkProfiler is a free online tool that gives you a reasonable look at any domain’s backlink profile without requiring an account or sign-up. It’s genuinely useful for quick competitor checks when you don’t have a paid subscription. And the CSV export means you can actually do something with the data.

Key Features:

• Free backlink analysis for any domain, no registration required
• Referring domain and anchor text overview
• Industry category classification for linking domains
• Link influence score for quick quality assessment
• Export backlink data to CSV

Limitation: Database is smaller than paid tools. Use it for directional insights rather than comprehensive audits.

10. SpyGlass (SEO PowerSuite)

SpyGlass is the backlink component of SEO PowerSuite. It pulls data from multiple sources including Ahrefs, Majestic, and Moz APIs and cross-references them. The penalty risk assessment feature is more detailed than you’d expect from a free tool, and the desktop app means your data stays local.

How to Check Backlinks of Website Using These Tools?

Knowing how to check backlinks of website is straightforward once you’ve picked a tool. But there’s a sensible order to do  it well.

Step 1 — Pick the right tool for the job. 

For your own site with no cost, use Google Search Console. & competitor checks or deeper analysis, Ahrefs’ free checker gets you the top 100 links with no account. Do a full audit, you’ll want a paid plan on Ahrefs, SEMrush, or Moz.

Step 2 — Enter the domain or URL. 

Paste the full domain (e.g., yourwebsite.com) or a specific URL into the search bar. If you’re auditing a competitor, start at the root domain level first before drilling into individual pages.

Step 3 — Review total backlinks and referring domains together. 

A site with 500,000 backlinks but only 300 referring domains is a red flag. That’s mostly a handful of sites linking repeatedly, not a healthy diverse profile. The referring domain count usually tells you more than the raw backlink number.

Step 4 — Analyze anchor text. 

Look at the distribution. A natural profile has a mix of branded anchors, generic anchors like “click here” or “read more,” and some topical partial-match anchors. If you see a lot of exact-match commercial anchors, that’s the kind of pattern that historically precedes a Google penalty.

Step 5 — Check for toxic or spammy links. 

Use Moz’s Spam Score or SEMrush’s toxicity score to flag suspicious links. Don’t go disavowing everything that looks slightly off. You’ll do more harm than good. Focus on obvious link schemes or any pattern that looks like negative SEO.

Step 6 — Run a competitor backlink analysis using backlink analysis tools.

This is where most of the real value is. Enter a competitor’s domain, find their strongest backlinks, then run a Link Intersect or Backlink Gap analysis to find domains that link to multiple competitors but not to you. Those are your warmest prospects. 

Step 7 — Export and actually use the data. 

Export to CSV. Build a prospect list. Track which links you’ve acquired over time. Checking backlinks once and forgetting about it doesn’t move rankings. The teams that get the most from these tools run monthly checks and act on what they find.
