Best Backlink Checking Tool in 2026: 8 Tools Compared

Ahrefs Site Explorer remains the reference tool for backlink research. Its live index holds tens of trillions of links, refreshed every 15 to 30 minutes in recent comparisons, and reports such as Link Intersect show which sites link to competitors but not to you. Domain Rating and URL Rating give fast authority signals for triaging prospects, while new and lost link reports track profile changes over time.

The Lite plan at $129 a month is a real cost for a solo site owner, and Ahrefs offers a cheaper Starter plan at $29 a month in some comparisons, though limits are tighter. For serious link building, outreach, or agency work, Ahrefs data depth justifies the price. For a simple check of your own site, start with free tools first.

Semrush pairs a large backlink index, reported at over 43 trillion links, with keyword research, rank tracking, content tools, and a link building outreach workflow. Its backlink audit helps flag toxic links and prepare disavow files, while gap analysis shows competitor links you lack. For a team that needs SEO beyond links, that breadth is the main reason to choose Semrush over a link-only tool.

Entry pricing is $139.95 a month after an August 2026 repackaging in recent comparisons, which is the highest entry price here. Limits and credits vary by plan, so check backlink report allowances before signing. For an all-in-one SEO team, Semrush breadth is worth the premium.

Majestic is a link-only specialist, known for Trust Flow, which estimates link quality, and Citation Flow, which estimates link quantity. Together they help you judge whether a linking site looks trustworthy or merely link-heavy, which is useful when vetting prospects or auditing a profile. Its historic index also helps forensic checks on domains you may buy.

Majestic lacks keyword research, rank tracking, and content tools, so most teams pair it with another suite. The Lite plan at $49.99 a month is affordable as a second opinion tool. For link quality judgment alone, Majestic remains a trusted standard.

Moz Pro includes Link Explorer, which reports linking domains, anchor text, and Spam Score, plus Domain Authority, a widely cited authority metric. Starter pricing is reported at $49 a month, with Standard at $99 a month in some comparisons, and a free tier of limited queries lets new users test the tool. Reporting is clear for client work, which helps agencies explain link quality.

Index refresh, reported every few days in some comparisons, is slower than Ahrefs or Semrush, and smaller sites may see fewer links. For prospect vetting with Domain Authority and Spam Score, Moz is still useful, especially as a second check alongside Ahrefs.

SE Ranking is an all-in-one SEO suite with backlink monitoring, rank tracking, site audits, and white-label reporting for agencies. Its backlink checker includes a toxicity score and disavow export, which helps agencies clean client profiles. Entry pricing is reported around $52 to $65 a month depending on billing, with Core plans listed at $129 a month in some 2026 comparisons, so confirm current pricing before signing.

Its backlink index, reported around 2.7 trillion links, is smaller than Ahrefs or Semrush, which can matter for deep competitor research. For agency monitoring, reporting, and value across many clients, SE Ranking is a strong budget all-in-one pick.

Serpstat offers keyword research, rank tracking, site audits, and backlink analysis in one suite, with entry pricing reported around $50 to $59 a month. Its link tools include domain rank, link intersection, and backlink reports that suit small teams doing competitor research on a budget. Many features are included on the starter plan, unlike suites that gate tools by tier.

Backlink depth lags Ahrefs and Semrush, so deep link research may need a second tool. For a small team that wants one affordable suite for SEO plus links, Serpstat is a practical choice, with a trial to test data coverage for your niche.

Ubersuggest, from Neil Patel, is the most beginner-friendly tool here, with simple backlink reports that show linking domains, authority, and new or lost links without a steep learning curve. It also bundles keyword ideas and content suggestions, which helps small site owners plan both links and content. Entry pricing is reported at $29 a month for Individual plans, with limited free searches per day.

Depth is thinner than Ahrefs, Semrush, or Majestic, so agency link research will outgrow it. For a beginner who wants a readable first look at a backlink profile and a low price, Ubersuggest is a good starting point.

Linkody focuses on monitoring rather than deep research. It tracks your backlinks, alerts you to new or lost links, and helps automate disavow files, at a low entry price of $14.90 a month in recent comparisons. That simplicity suits site owners who mainly want to watch their own profile over time, rather than research competitors in depth.

For competitor gap analysis or prospecting, Ahrefs or Semrush give far more data. Linkody works best as a monitoring companion, paired with a research tool or with Google Search Console for your own site. Its low price makes that pairing affordable.
