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)

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 ($139.95/month Pro)

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)

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: Free (10 queries/month), $99/month (Moz Pro)

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.

The free version provides 10 link queries per month, which is 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: $25/month (1 domain, 2 competitors)

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 two 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: $14.90/month (2 domains)

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.

The data comes from Moz's API, so the index limitations apply here too. But at $14.90/month, it is the cheapest option for ongoing backlink monitoring.

Which Should You Pick?
