Best Backlink Analysis Tools in 2026

Backlinks remain one of the strongest ranking signals in Google's algorithm. Knowing who links to you, who links to your competitors, and where link opportunities exist gives you a massive advantage. These tools help you analyze backlink profiles, discover link building prospects, and monitor your link health over time.

Quick Comparison

1. Ahrefs Backlink Checker

Best for: The most comprehensive backlink data available Price: $129/month (Lite), $249/month (Standard). Annual billing drops these to roughly $108 and $208 per month, a saving of about 17 percent. A free Backlink Checker (top 100 links for any site) and the free Ahrefs Webmaster Tools (up to 1,000 backlinks for sites you verify, no credit card) are both available without a paid plan.

Ahrefs has the largest backlink index in the industry. It crawls over 8 billion pages daily and maintains a database of trillions of known links. When you enter a domain or URL, you see referring domains, backlink count, anchor text distribution, link growth over time, and the Domain Rating (DR) metric.

The "Best by links" report shows you which pages on any site attract the most backlinks, which is incredibly useful for content strategy. The "Link Intersect" tool finds sites that link to your competitors but not to you. These are your easiest link building targets.

The "Broken backlinks" report surfaces links pointing to 404 pages on your site or competitors' sites. Reclaiming your own broken links and reaching out about competitors' broken links are two of the highest-ROI link building tactics.

Ahrefs is the gold standard here. If you are serious about link building, this is the tool.

2. SEMrush Backlink Analytics

Best for: Competitive link gap analysis Price: Included with Semrush. Pro is $139.95/month, Guru is $249.95/month, and Business is $499.95/month, each with a 7-day free trial. Annual billing cuts roughly 17 percent off, bringing Pro to about $117 per month. Extra user seats and add-ons such as the AI Visibility Toolkit (about $99/month) are billed separately.

SEMrush's backlink tool is strong on competitive analysis. The "Backlink Gap" feature lets you compare up to 5 domains side by side and find sites that link to your competitors but not you. This is essentially a ready-made prospecting list.

The "Backlink Audit" tool evaluates your existing links for toxicity using a score based on multiple signals. It integrates directly with Google Search Console to submit disavow files if needed. The "Link Building" tool combines outreach management with prospect discovery, which is convenient if you want everything in one platform.

The data quality is close to Ahrefs but the index is slightly smaller. Where SEMrush wins is in the workflow. Finding prospects, managing outreach, and tracking results all happens in the same tool.

3. Majestic

Best for: Historical link data and trust metrics Price: $49.99/month (Lite), $99.99/month (Pro), $399.99/month (API). Lite includes Fresh Index access and 1 million analysis units per month; Pro adds the Historic Index, raw data exports, and 20 million analysis units. The API tier opens full programmatic access and supports up to 5 users. Annual billing drops Lite to about $41.67 per month.

Majestic has been crawling the web since 2004, which gives it one of the deepest historical backlink databases. The "Fresh Index" shows recent link data, while the "Historic Index" goes back years. This historical perspective is valuable for understanding how a site's link profile has evolved.

Majestic's proprietary metrics, Trust Flow and Citation Flow, are widely used in the industry. Trust Flow measures link quality based on how close a site is to trusted seed domains. Citation Flow measures link quantity. The ratio between the two gives you a quick quality signal.

The "Topical Trust Flow" feature categorizes links by topic, which helps you see if your backlinks are relevant to your niche. The interface feels dated compared to Ahrefs or SEMrush, and there is no keyword research or rank tracking included. But for pure link analysis, Majestic is hard to beat at its price point.

4. Moz Link Explorer

Best for: Domain Authority as an industry metric Price: A free Moz Community account gives limited Link Explorer access; paid Moz Pro runs $49/month (Starter), $99/month (Standard), $179/month (Medium), and $299/month (Large), with roughly 20 percent off on annual billing and a 7-day free trial. Domain Authority remains the most widely referenced authority score in SEO discussions.

Moz created the Domain Authority (DA) metric, which, despite its limitations, is still the most widely referenced authority metric in SEO discussions. Link Explorer gives you DA, Page Authority, linking domains, anchor text, and spam score for any URL.

A free Moz Community account provides limited Link Explorer queries, enough for occasional checks. The "Discovered and Lost" report tracks new and lost links over time. The "Spam Score" helps identify potentially harmful links in your profile.

The link index is significantly smaller than Ahrefs or Majestic. For comprehensive link analysis, you will want to use Moz alongside another tool. But if DA is a metric your clients or team care about, Moz is where you get it.

5-6. Honorable Mentions

Monitor Backlinks

Best for: Affordable link monitoring with email alerts Price: Backlink monitoring is delivered through the SEOptimer platform, starting at $39/month on the White Label plan (check current pricing)

Monitor Backlinks focuses on tracking your link profile over time. It sends email alerts when you gain or lose backlinks, which is useful for catching negative SEO attacks or knowing when an outreach campaign pays off. The competitive tracking lets you monitor up to five competitor domains alongside your own.

The tool is straightforward and does not try to be an all-in-one suite. If you already have Ahrefs or SEMrush for research and just need ongoing monitoring, this is a good complement at a lower price point.

Linkody

Best for: Small businesses on a tight budget Price: EUR 13.90/month (Webmaster, 2 domains, 500 monitored links). Higher tiers run up to EUR 138.90/month (Agency XL, 100 domains, 50,000 links). A 30-day free trial needs no credit card.

Linkody is a simple link monitoring tool that tracks your backlinks, alerts you to changes, and provides basic metrics like link status (dofollow/nofollow), anchor text, and Moz DA. The disavow file generator is handy for quickly creating and maintaining your disavow list. Projects refresh automatically every 24 hours.

The data comes from Moz's API, so the index limitations apply here too. But at EUR 13.90/month for the entry plan, it is among the cheapest options for ongoing backlink monitoring.

Which Should You Pick?

• Best overall: Ahrefs. The largest index, best data quality, and most useful reports for link building.
• Best free option: Ahrefs Webmaster Tools (free for verified site owners, shows up to 1,000 links to your own site, no credit card) or the free Moz Community account for limited Link Explorer queries.
• Best for beginners: Moz Link Explorer. Simple interface, DA is easy to understand.
• Best for agencies: SEMrush. The combined outreach and analysis workflow saves time when managing multiple clients.
• Best budget pick: Majestic Lite at $49.99/month. Deep data at a fraction of the Ahrefs and Semrush price.

By the Numbers (2026)

Current pricing and key specs, each verified on the vendor's own page on 2026-05-29 (full URLs in Sources).

A few details worth flagging. Ahrefs and Semrush both discount roughly 17 percent for annual billing, so the headline monthly figure is the most expensive way to buy. Semrush charges separately for extra user seats and add-ons such as the AI Visibility Toolkit (about $99/month). Linkody has moved to euro pricing, so the dollar figure shifts with the exchange rate. Monitor Backlinks now lives inside the SEOptimer platform, so confirm the live plan before committing.
