Which backlink checker helps you find opportunities, and how do you turn those opportunities into a content strategy?
Backlink checker tools are still an essential part of any SEO toolkit in 2026. Sure, Google talks non-stop about E-E-A-T and helpful content as the signals that matter a lot. But at the end of the day, search algorithms still care deeply about a site’s backlink profile to figure out who matters in a niche and who is likely making noise. That's why we share our picks for the best SEO tools to check backlinks that’ll help you keep your site’s profile healthy and find new link building opportunities.
What Metrics to Look For in SEO Tools to Check Backlinks?
The best SEO tools to check backlinks should give you enough information to judge the links, ideally in a user-friendly, easy-to-read way. While every platform tracks dozens of secondary metrics, here are the core data points that’ll help you cut through the noise.
Referring Domains vs. Total Backlinks
Total link counts look impressive on paper, but they're easily inflated. In contrast, referring domains are where you need to look in the first place. Getting one unique link from 50 reputable websites each is way more valuable than getting 500 links from the same niche forum.
Link Attributes (Dofollow vs. Nofollow)
Dofollow links pass authority directly to your URLs. Nofollow links don't pass link juice directly. However, they're still part of a natural-looking backlink profile. As a result, a dofollow-only profile actually looks suspicious. Nofollow links are also useful for helping search engines understand context. And they can still help with referral traffic and brand signals, too.
Anchor Text Distribution
Anchor text is the clickable wording inside the hyperlink. Ideally, a healthy anchor text profile doesn’t lean too heavily on commercial keywords and is diversified with everything from branded terms to natural phrases. For a broader framework, learn how to use natural anchor text that helps readers and search engines understand context without over-optimization.
Domain Authority (Rating)
Most major tools have their own metrics to measure website authority and link quality. For example, Semrush has Authority Score. Moz uses Domain Authority (DA), while Ahrefs has proprietary Domain Rating (DR). These scores aren’t official Google metrics, but they all try to answer roughly the same question: how strong is this website's backlink profile compared with other websites?
New and Lost Backlinks
Tracking new backlinks helps you understand which of your content pieces are gaining traction. On the other hand, lost backlinks are warning signals. They can show that some of your partners or high-value publications have dropped your link.
Top-Rated SEO Tools to Check the Backlinks of Any Website
There's no shortage of SEO tools to check backlinks out there. Some features are really great but may not fit your use case well, so let’s break down what each is good at and exactly who it's built for.
Collaborator Free Backlink Checker
The Collaborator Free Backlink Checker is a no-cost way to check who links to your website.
Data comes from SE Ranking's database, which covers 2.9 trillion backlinks and 411 million referring domains. On top of that, 58% of links are refreshed once in 90 days.
And here’s a unique feature of Collaborator’s SEO backlink checker: it doubles as a link building tool. If a referring domain is available in the Collaborator marketplace, you’ll see this. Collaborator makes it easy to reach out or arrange a placement directly through the platform.
Metrics shown: dofollow/nofollow attributes, anchor text, first discovery & last check dates, and authority metrics - Domain and Page InLink Rank. All the core metrics you need to evaluate link quality at a glance.
Competitor research value: high. Top 50 strongest and 50 newest links shown allow you to see where your competitor is earning attention right now.

Good for: anyone looking for an SEO tool that lets you move from backlink checking to link building without a lot of extra steps.
SEOptimer Free Backlink Checker SEO Tool
SEOptimer is another solid pick among SEO tools to check backlinks, covering the essential data you need for backlink analysis, while its paid plan turns it into a strong website audit tool. In 2023, the company acquired Monitor Backlinks, so SEOptimer received many of its features - backlink status tracking included (active, lost, or broken links over time).
Metrics shown: Domain Strength & Page Strength. Totals for links and referring domains, follow vs. nofollow balance, anchor text. Add-ons like edu & gov links and linking IP subnets.
Competitor research value: focused. If a site’s backlinks are concentrated in some server clusters or countries, you’ll see this.
Link-building use benefits: low. This tool is more about backlink research than turning those findings into outreach efforts.
Strengths: well-structured report with easy-to-digest visuals, which includes technical data like IP subnets.
Limitations: a very restricted number of rows displayed in a free variant. SEOptimer's backlink index is also smaller than that of alternatives like Semrush or Ahrefs.

Moz Link Explorer
The Moz Link Explorer offers its own metrics that act as a measure of quality control when it comes to assessing backlink value and the authority of outreach prospects.
Metrics shown: this tool brings quite a lot of parameters to your attention, including.
- Domain Authority (DA), a proprietary 0-100 score that most SEOs still use as a reference for site strength;
- Page Authority (PA), another metric developed by Moz. It gives you an idea of how strong a specific page is when it comes to ranking in SERP;
- Spam Score is based on patterns that show up on domains similar to sites Google has penalized or banned.
Competitor research value: high. The Link Intersect report shows which sites are linking to your competitors but not to you.
Link-building use benefits: high. The above-mentioned report is a ready-made shortlist for link prospecting.
Strengths: Domain Authority is a highly trusted parameter. Moreover, Moz's backlink index has over 44 trillion links.
Limitations: requires creating a free account, which is quite restricted with 10 free monthly queries and limited rows.
Good for: telling which link opportunities are good and which are problematic, so that you can focus on quality outreach.
Majestic Backlink Checker (Site Explorer)
The Majestic Backlink Checker is a highly specialized tool. While many other platforms offer broader SEO suites, Majestic has stayed lazer-focused on backlinks.
Metrics shown: Trust Flow (quality) and Citation Flow (link volume) - Majestic’s most recognized data. In addition, you'll see Topical Trust Flow across various categories, Fresh and Historic link indexes, referring IPs, and anchor text.
Competitor research value: high. The data offered by this backlink checker helps you understand not just how many links a competitor has, but what kind of links they are earning and how relevant those links are topically.
Link-building use benefits: invaluable for checking relevance. Comparing Trust Flow against Citation Flow, you can tell right away if a prospect has true niche authority.
Strengths: detailed topic-level analysis and historical link archives.
Limitations: the free tier only gives summaries and some charts. This isn’t your typical all-around SEO tool; the interface is backlink data focused and doesn't offer extras like keyword research or rank tracking like other SEO tools.
Good for: individual SEOs and agencies who seek extra depth in backlink analysis.
Semrush
If you're looking for SEO tools to check backlinks that do everything, Semrush is part of your considerations for sure. With a paid subscription, features like backlink analysis, keyword research, rank tracking, and site auditing are all present in one dashboard.
Luckily, you can get a small taste of what the platform can do at no cost. The Semrush free backlink checker gives you 3 searches per day without registration.
Metrics shown: a free backlink checker provides basic metrics – Authority Score (AS), totals for backlinks and referring domains, dofollow %. A paid version has everything from new and lost link tracking to full-fledged link building tools for outreach campaigns.
Competitor research value: medium for a free tier – it gives you a high-level yet brief look at a rival’s overall authority and link growth trajectory. High for a paid version, with its domain-to-domain comparisons and a wealth of historical data.
Link-building use benefits: low for a free variant that’s too restricted, ultra-high for a paid plan as Semrush is actually an end-to-end outreach engine.
Strengths: backlink database covers a whopping 43 trillion links and Semrush updates it every 15 to 30 minutes.
Limitations: the price starts at $139.95/month and goes up drastically with more upgraded plans. Besides that, the free backlink checker allows just 3 queries a day and 15 rows of data.
Good for: Business owners looking for a trustworthy all-in-one SEO platform.
Keywords Everywhere Backlinks Checker
Keywords Everywhere offers a free Backlinks Checker on its site. Paste in a URL or a domain and it goes and finds every page it can that links back to it, pulling up the anchor text and a few authority scores for each one so you get a quick read on link quality.
Metrics shown: anchor text, Domain Authority (Moz's 0-100 score), Page Rank on a 0-10 scale, and Spam Score.
Competitor research value: decent. You can check one URL or domain at a time, or switch to bulk mode and queue up to 100 at once while it processes them in the background. Handy if you're sizing up several competitor pages together.
Link-building use benefits: low. It's a research tool through and through, there's no outreach features or contact info to help turn what you find into an actual placement.
Strengths: it's smart about telling links apart from domains on its own. Drop in something starting with http:// or https:// and it checks that exact page, the tool treats anything else as a whole domain.
Limitations: free plan tops out at 500 backlinks per target. And like most backlink tools, it's not catching every single link out there, smaller or newer pages might be missing simply because the tool hasn't crawled them yet.
Good for: quick, no-signup backlink lookups on a single page or a batch of competitor URLs.
Monitolink: Backlink Monitoring Tool
Monitolink is dedicated backlink monitoring software that monitors your link profile, flagging new links as they appear and alerting you the moment an existing one goes missing or turns nofollow.
Metrics shown: Link status changes (new, lost, nofollow-switched), anchor text shifts over time, referring domain authority, and same-day alerts for each monitored target.
Competitor research value: Strong for tracking trends. You can view a competitor's full backlink details and velocity, and compare them to yours using a “Link Intersect” score that shows you sites that link to your competitors but not you.
Link-building use benefits: With Monitolink, you’re protecting the ones you've already earned, so you catch lost placements early enough to follow up and get them restored. It has a built-in link reclamation feature that lets you reach out to website owners when your backlink status changes.
Strengths: Automated same-day alerts mean you don't have to manually re-run checks to catch changes; useful for ongoing campaign upkeep rather than one-off audits. White-label reports, if you’re working with clients, and AI backlink profile analysis that flags major issues in 60 seconds.
Limitations: Since it's monitoring-focused, it's not the tool to reach for if you're starting cold outreach or need a broad one-time competitor snapshot.
Good for: Site owners, SEOs, and agencies who already have a backlink profile worth protecting and want to be notified automatically when it changes.
Turn backlink data into a content strategy with StoryChief
A backlink checker can show you which pages earn links, which competitors attract authority, and where valuable links disappear. But a report alone does not improve your rankings.
The next step is turning those findings into a clear content workflow.
With StoryChief, content and SEO teams can use backlink insights to:
- Find link-worthy topics: Review the competitor pages that attract high-quality referring domains, then create a sharper, more useful angle your audience will actually want to reference.
- Prioritize content refreshes: When an important page loses backlinks or stops attracting them, add it to your content calendar and assign the refresh to the right editor or SEO owner.
- Build supporting topic clusters: Use backlink patterns to identify the themes your competitors own, then plan related articles that strengthen your topical coverage over time.
- Coordinate content and outreach: Create the pillar page, supporting articles, expert quotes, social posts, and distribution plan in one shared workspace, rather than managing link-building support through scattered documents.
- Measure the impact beyond links: Backlinks matter, but they are not the final outcome. Track whether refreshed and newly published content earns more search visibility, clicks, and business attention.
The takeaway: backlink data needs a content workflow
The best backlink checker is the one that gives you reliable data you will use regularly. But backlink data only becomes valuable when it changes what your team creates next.
Use backlink tools to spot authority gaps, competitor content that earns attention, lost links, and pages worth improving. Then use StoryChief to turn those insights into an organized content plan, assign the work, create supporting assets, publish across channels, and measure whether your efforts increase search visibility.
Backlinks still help search engines understand which sites and pages deserve attention. The teams that win are the ones that connect link insights to consistently useful content, not the ones that collect the most reports.
Turn SEO insights into a content plan your team can execute. Create, collaborate on, distribute, and measure content in StoryChief.
