14 Best Backlink Checker Tools in 2026 (Free & Paid)

Most "best backlink checker" roundups rank tools by feature count. We did something different: we pulled our own Search Console data first to see what people actually search for around backlink checkers, then built this list around real gaps, like the fact that almost nobody explains why the same website gets a Domain Rating of 60 on Ahrefs and a Domain Authority of 40 on Moz. That inconsistency alone sends people looking for a "trust tool" that doesn't exist by that name; it's really a question about which quality metric to believe.

Backlinks are still one of the strongest signals Google uses to rank a website. A link from another site acts as a vote of confidence, and the more high-quality votes a page has, the better it tends to rank. Keeping track of who's linking to you, and to your competitors, means using a backlink checker tool. The tools below range from fully free, first-party data straight from Google, to paid platforms indexing over a hundred billion backlinks with their own trust scoring on top. Fourteen compared, pricing checked live, no fabricated test claims, just what each one actually does and what it costs. If you're assembling a broader toolkit beyond just backlinks, our list of free digital marketing tools covers the rest of that stack.

Pricing below was confirmed live in August 2026; SEO tool pricing changes often, so double-check before you buy.

30-Second Decision

Short on time? Here's the fast answer.

• Zero budget: Google Search Console (your own site only) + Open Link Profiler (anyone's site, free).
• One serious paid tool, best overall data: Ahrefs.
• Best value for the data you get: SE Ranking or Majestic.
• Cheapest paid option that isn't a toy: Linkody, $14.90/month.
• Already need keywords + content + backlinks in one login: Semrush.
• Just want to watch your links over time, not research: Linkody.

Quick Comparison

How We Evaluated These Tools

We looked at four things for each tool: database size and freshness (how many backlinks it's indexed and how often that's updated), link-quality metrics (does it tell you if a backlink is actually good, not just that it exists), price-to-value fit for different budgets, and ease of use for someone who isn't a full-time SEO analyst. No tool wins on all four. That's the whole point of comparing them instead of just picking the biggest name.

Tools below are grouped Free → Paid, then ordered within each group roughly by database depth and market recognition. This isn't a strict #1-to-14 ranking, since which one is actually "best" depends on your budget and use case; see the 30-second decision box above for that.

Best Free Backlink Checker Tools

Google Search Console

Google Search Console (formerly Webmaster Tools) is the one source on this list that's guaranteed to reflect what Google itself has indexed, because it's Google's own data, not a third party's crawl of the web. It shows external and internal links, top linking sites, and the anchor text being used, plus lets you flag links you believe are harmful.

Pros

• Completely free, no limits
• Data comes directly from Google, no third-party crawling delay or gaps
• Doubles as your site's crawl-error, indexing, and performance dashboard

Cons

• Only shows backlinks to your own verified site, can't check competitors
• Less detailed than paid tools (no Domain Authority-style scoring, limited filtering)
• Data can lag behind real-time by a few days

Verdict: Every website owner should have this connected regardless of which paid tool they also use. It's the free baseline everything else gets checked against.

Open Link Profiler

No account needed. Enter a domain and get a backlink report immediately, including an estimate of toxic or spammy links that could be hurting your rankings.

Pros

• Zero signup friction
• Flags potentially toxic links specifically
• Shows anchor text and estimated domain authority per link

Cons

• Data freshness and depth lag well behind Ahrefs/Semrush-tier tools
• No historical tracking or alerts
• Interface feels dated, and the site can be ad-heavy

Verdict: Good as a free second opinion, especially for a quick toxic-link gut-check, but not a primary tool for serious link-building work.

Rankwatch Backlink Checker

Rankwatch's standalone backlink checker is genuinely free, separate from its paid rank-tracking suite, and covers dofollow/nofollow breakdown, referring domains, and anchor text distribution for any URL, including competitors.

Pros

• Free, and works on competitor domains too, not just your own
• Historical data available
• Bundled with other free SEO tools (mobile-friendliness, site analyzer)

Cons

• Shallower database than the big paid players
• Upsells toward its paid plans throughout the interface

Verdict: The best free option here if you specifically need to check a competitor's backlinks without paying.

Best Paid Backlink Checker Tools

Ahrefs

Ahrefs is widely considered the industry standard for backlink data. It's frequently cited in link-building surveys as the tool professionals trust most for accuracy, and its Domain Rating (DR) and URL Rating (UR) scores are the fastest way to eyeball link quality without digging into raw numbers. Its free checker now requires a signup to see full results, which wasn't the case previously.

Pros

• Among the largest, most frequently updated backlink indexes available (index refreshes every 15 minutes)
• DR/UR scoring makes link quality easy to judge quickly
• Bundles keyword research, content, and rank tracking in one subscription

Cons

• No free trial, and its once free-and-open backlink checker now sits behind a signup wall
• Starts at $129/month, one of the pricier options here
• Steeper learning curve for beginners

Verdict: If backlink accuracy is non-negotiable and budget allows, this is the safest first choice.

Semrush

Semrush's Backlink Analytics breaks your profile down by industry, country, TLD, link type, anchor text, and an Authority Score. It's useful when you need to present a polished report, not just raw data.

Pros

• One of the largest backlink databases (160B+), updated every 15 minutes
• Strong reporting/visualization for client-facing summaries
• Full SEO suite (keywords, site audit, competitor research) included

Cons

• Most expensive entry point on this list
• Can feel like overkill if backlinks are your only need

Verdict: Best if you want backlink data as one part of a full SEO toolkit, not a standalone checker.

SE Ranking

Co-founded in 2013 by Valery Kurilov and Dmitri Lipnitsky, SE Ranking pairs backlink analysis with rank tracking, technical audits, and local SEO features.

Pros

• Tracks Google, Bing, and Yahoo rankings, not just Google
• Clean, beginner-friendly interface
• Still meaningfully cheaper than Ahrefs/Semrush at the entry tier

Cons

• Backlink database is smaller than Ahrefs/Semrush
• No longer the budget option it once was, price has roughly doubled since early 2025
• Some advanced filtering feels less polished

Verdict: Still solid if you want most of what Ahrefs/Semrush offer, at a real but smaller discount to their price.

Majestic

Majestic has a genuinely unusual origin story for an SEO tool: it began in 2004 as an open-source, volunteer-powered web crawler called Majestic-12, founded by Alex Chudnovsky, before pivoting to the commercial Majestic SEO in 2008. That crawling history is part of why its quality framework, Trust Flow and Citation Flow, is still referenced across the industry as a way to separate genuinely authoritative links from high-volume, low-trust ones.

Pros

• Deep historical link index, useful for tracking link-building progress over time
• Trust Flow/Citation Flow is a genuinely useful quality lens other tools don't replicate exactly
• Cheapest entry point among the "big name" tools, and the price has stayed flat for years

Cons

• Interface and reporting feel less modern than Ahrefs/Semrush
• Doesn't bundle keyword research or content tools, backlinks only

Verdict: Best pick specifically for judging link quality, not just counting links.

Moz Link Explorer

Moz popularized Domain Authority (DA) and Page Authority (PA), metrics still used informally across the industry as shorthand for site strength, even by people who don't use Moz itself. Its client list includes Trivago, Zillow, and the agency Razorfish, among others.

Pros

• Longest free trial on this list (30 days)
• DA/PA are broadly recognized, easy to explain to clients unfamiliar with SEO
• Flags spammy/harmful links automatically

Cons

• Backlink index is generally considered smaller than Ahrefs/Semrush
• Pricing jumps steeply at higher tiers

Verdict: Good if you specifically want DA/PA reporting clients already recognize, otherwise Ahrefs or SE Ranking likely edge it out on raw data depth.

Serpstat

Serpstat covers keyword research, competitor analysis, site audits, and backlink tracking in one subscription, aimed at teams that want breadth without paying Semrush-level prices.

Pros

• Broad feature set for the price
• Competitor backlink comparison included
• White-label, branded client reports

Cons

• Backlink-specific depth is thinner than dedicated tools like Ahrefs/Majestic
• Plan tiers vary, so confirm exact pricing for your usage level before buying

Verdict: Solid if backlinks are one of several things you need covered, not your main focus.

Seobility

Seobility grew from a free tool into a full platform, pairing backlink tracking with technical/on-page audits (meta tags, duplicate content, internal linking) at a lower price than most competitors here.

Pros

• Competitive, stable pricing for combined backlink + technical audit features
• White-label reporting for agencies
• Tracks follow/nofollow split and referring domains clearly

Cons

• Smaller backlink database than the market leaders
• Less name recognition, fewer third-party integrations

Verdict: A reasonable mid-budget pick if you want backlinks and technical SEO audits from one login.

Linkody

Founded in 2012 by François-Louis Mommens, Linkody is built specifically for ongoing monitoring rather than one-off lookups. It alerts you the moment you gain or lose a backlink and can auto-generate a disavow file for Google.

Pros

• Cheapest paid, non-trial-limited entry point on this list
• Real-time new/lost backlink alerts
• Automated disavow list generation, saves manual toxic-link cleanup work

Cons

• Narrower focus (monitoring) than full-suite competitors, no keyword or content tools
• Higher tiers needed for larger sites (Agency XL runs $153.90/month)

Verdict: Best if your main need is watching your link profile change over time, not deep one-time competitor research, and now also the budget pick.

LinkMiner (by Mangools)

Part of the Mangools SEO suite, LinkMiner keeps its interface deliberately simple. Link Quality Score, Domain Authority, and Trust Flow are all shown at a glance without digging through menus.

Pros

• Genuinely beginner-friendly interface
• Trusted by recognizable brands (Airbnb, Adidas, and Skyscanner cited as users)
• Bundled with the rest of the Mangools toolkit (keyword, rank tracking)

Cons

• Backlink database smaller than dedicated backlink specialists
• Only useful at full strength within the Mangools ecosystem

Verdict: Good starting point for beginners who find Ahrefs/Semrush's interfaces overwhelming.

Ubersuggest

Neil Patel's Ubersuggest used to be the cheapest full subscription on this list by a wide margin. That's no longer true: its entry price jumped from $12 to $29/month, which puts it above Linkody and Majestic. It's still aimed at beginners who want basic backlink visibility alongside keyword research and content tools, just no longer at a bargain price.

Pros

• Combines backlinks with keyword research and site audit in one place
• Simple enough for non-SEO-specialists
• A lifetime-purchase option exists, unusual for this category

Cons

• No longer the cheapest tool here, price roughly doubled
• Backlink data depth is noticeably behind the specialist tools

Verdict: Was the default budget pick for years; check Linkody or Majestic first now that the price gap has closed.

SEO SpyGlass

Unlike everything else on this list, SEO SpyGlass is desktop software you install rather than a web app. Worth a look if you'd rather own a license than pay a recurring subscription. It's sold as part of the SEO PowerSuite bundle, so confirm the current standalone price directly with the vendor before buying.

Pros

• Free tier available, paid tier is a flat yearly fee rather than monthly
• Over 50 backlink-quality metrics, one of the most detailed breakdowns here
• Can compare up to 5 sites' backlink profiles at once

Cons

• Desktop-only, no cloud dashboard, less convenient for teams
• Standalone pricing is bundled with SEO PowerSuite, less transparent than a simple monthly fee

Verdict: Worth considering only if you specifically prefer a one-time desktop purchase over a subscription.

Authority Metrics Explained: Why the Same Site Gets Different Scores

Check the same domain on Ahrefs and Moz and you'll often get two different numbers, DR 60 on one, DA 40 on the other. That's not an error. Each tool built its own scoring system on its own crawl of the web, and none of them see the exact same set of links.

• Domain Rating (DR), Ahrefs' metric, scores 0-100 based on the quantity and quality of external backlinks to a domain, weighted logarithmically so a few extra links matter less once you're already strong.
• Domain Authority (DA), Moz's metric, is a 0-100 predictive score of how well a domain is likely to rank, based on Moz's own link index, not a direct measure of link count.
• Trust Flow / Citation Flow, Majestic's pair of metrics, separates "how many links point here" (Citation Flow) from "how trustworthy are the sites sending them" (Trust Flow). A big gap between the two is the clearest signal of a spammy link profile.
• Authority Score, Semrush's metric, blends its own backlink data with organic traffic and spam signals into a single 0-100 number.

None of these is "the real one." They're four different opinions built on four different, overlapping-but-not-identical databases. The practical takeaway: don't chase a specific number on a specific tool. Check the trend over time on whichever tool you use consistently, and cross-reference with Google Search Console (the one source that actually reflects what Google itself indexed) before making a real decision, like whether to disavow a link or pursue a partnership.

How to Spot a Bad (Toxic) Backlink

Not every backlink helps you. Links from spammy, unrelated, or low-quality sites can actively hurt your rankings, and most of the tools above will flag them automatically, but it's worth knowing what they're actually looking for. A few signals worth checking yourself: a big gap between Citation Flow and Trust Flow (see above) is a red flag, since it usually means quantity without quality. So is an irrelevant niche, like a casino or pharma site linking to a business blog with no topical reason to. Unnatural anchor text, the same exact keyword phrase used across dozens of links, looks manipulated rather than organic. And a high spam score (Moz) or flagged-toxic status (Open Link Profiler, Linkody) is the tool's own automated red flag, worth checking first before you go link by link manually.

If you find toxic links, most tools above (Linkody, Ahrefs, SE Ranking) can generate a disavow file to submit to Google Search Console directly.

Checking backlinks is step one; actually earning more of the good ones is the natural next step. Our guide to link building tools and software covers that side of it.

FAQ

What are some free backlink checker tools? Google Search Console, Open Link Profiler, and Rankwatch's backlink checker are fully free with no trial period or credit card required. Ahrefs, Moz, and Semrush also offer limited free versions or free trials, but their full backlink data sits behind a paid plan, and Ahrefs' free checker now requires signup to see results.

Can I check backlinks using Google Search Console? Yes, but only for your own verified site, and only what Google itself has indexed for you. It won't show competitor backlinks, which is where a dedicated tool like Ahrefs or SE Ranking comes in.

Which tool is best for finding backlinks to a website? For depth and accuracy, Ahrefs and Semrush are the most widely trusted. For a tighter budget, Linkody and Majestic now offer the strongest data-to-price ratio, since SE Ranking and Ubersuggest both got significantly more expensive recently.

What's a good backlink quality score? There's no single universal number, and no tool's score is "more correct" than another's, see the Authority Metrics section above for why. What matters more than the exact number is the gap between quantity and quality metrics, and whether the linking site is topically relevant to yours.

Are backlink checker tools safe to use? Yes. Checking backlinks, your own or a competitor's, through a reputable tool is safe and doesn't affect either site. Stick to well-known providers rather than obscure free tools that ask for excessive account permissions.

Can a backlink checker tool find every single backlink pointing to my site? No single tool has a complete index of the entire web. Ahrefs, Semrush, and Majestic each crawl and index differently, so results vary between them. Cross-checking with Google Search Console, which reflects what Google itself has actually indexed, is the best way to catch gaps.

Can a backlink checker detect harmful or spammy backlinks? Most paid tools flag likely-toxic links using signals like spam score, unnatural anchor text, and low-trust linking domains. Treat these as a starting point for manual review, not a final verdict.

Which Tool Should You Actually Use?

Our take, after comparing pricing and data depth across all of these: there's no single "best" one, only a best fit for your budget and how deep you need to go. And that fit shifted in 2026, two tools that used to be the obvious budget picks (SE Ranking, Ubersuggest) got a lot more expensive, while two others (Majestic, Linkody) held their prices flat and are now the better deals.

• Just starting out, zero budget: Google Search Console + Open Link Profiler covers the basics for free.
• Need competitor data without paying: Rankwatch's free checker.
• Budget for one serious tool: Majestic, strong data without Ahrefs/Semrush pricing, and the price hasn't moved in a while.
• Money isn't the constraint, accuracy is: Ahrefs.
• Already running a full SEO workflow, want backlinks bundled in: Semrush.
• Ongoing monitoring, not one-off lookups, tightest budget: Linkody.
