A backlink platform shows who links to your site, who links to competitors, and which links may be harming your rankings. The best choice depends on whether you need the deepest index, the best outreach workflow, or the lowest price for a small site.

Ideal for: competitor backlink research

We compared official feature pages, pricing pages, app store listings, privacy policies, and public reviews for each option, and we kept only products that exist and work today and that truly fit the topic. We gave weight to clear pricing, a usable free or trial option where one is offered, and honest limits stated on the vendor site. We did not claim hands-on testing we did not do, and where a price could not be verified on the vendor site we wrote See website instead of guessing. Our pick for most people is usually the option that covers the core job well at a fair price, not the one with the longest feature list. That said, the right answer depends on your situation, so use the comparison table to narrow the list to two or three options, then check the current pricing page before you pay.
Start with your own profile before studying competitors. A free check in Search Console plus a trial of a paid tool shows whether your link profile has obvious problems worth fixing first.
Next, decide whether you need outreach or only analysis. Ahrefs and Majestic excel at analysis, while Semrush adds outreach and disavow workflows that save a second subscription.
Finally, watch the limits, not just the headline price. Report caps, credit systems, and project limits decide whether a plan survives a real month of work, so test with your largest competitor before paying.
Ahrefs is the best overall pick for depth and freshness, while Semrush is the best all-in-one choice. Majestic is the best budget specialist for judging link quality.
Google Search Console is the best free source for your own links, and Ahrefs offers a free checker showing the top links for any site. Both are limited compared with paid plans.
Enter a competitor domain in a tool like Ahrefs or Semrush, open its backlink report, and use the gap or intersect feature to find domains linking to rivals but not to you.
A toxic backlink is a link from a spammy or manipulative source that may harm rankings. Semrush and Ahrefs both flag risky links and support disavow files for Google.
Most sites benefit from a monthly check for new and lost links, plus a deeper audit each quarter. Sites running active link building should check weekly during campaigns.
