3rd Place: Majestic Review

Visit Website

Many marketing professionals consider Majestic one of the best backlink checkers on the market — and it gives you a powerful punch for your investment. You get full details about your site’s inbound links, including domain authority, new and lost backlinks, and a distribution breakdown of follow/nofollow and anchor text.

Majestic is well-known for its page authority metrics: Trust Flow (TF) and Citation Flow (CF). CF metrics show you the number of sites linked to your site, and TF metrics predict the quality of these backlinks. These metrics are now industry standards.

In 2019, Majestic launched Link Context, a new tool that gives you insights into what content surrounds every backlink you check, including text, other internal and external links, images, whether the main link is an editorial or directory link, and much more.

While Majestic’s backlink database is larger than Ahrefs, some SEO experts argue that its data isn’t quite as reliable as Ahrefs. Still, many users are extremely satisfied with Majestic’s results.



  • Free version
  • Largest backlink database available
  • Get recent and historic backlink profiles
  • Citation and trust flow metrics
  • Excellent ability to uncover new backlink opportunities
  • Helpful anchor text charts
  • Robust reporting
  • Other SEO tools like keyword tracking, keyword research, and site auditing are not included
  • Doesn’t give you email alerts for new, lost, and toxic backlinks
  • Some users say the UI is dated and not easy to use


All plans include a 7-day money-back guarantee.

Frequently Asked Questions

These are questions we’ve received from our readers.

What Happened To LINKCheetah?LINKCheetah logo

LINKCheetah was an affordable option if you were only looking for backlink analysis for your site. You got relatively basic but reliable data, including an overview of your site’s backlink profile, a Google index check, the ability to identify and remove bad links, follow/nofollow and anchor text distributions, and backlink monitor and notifications, all at an affordable price tag.

The Google cache page shows the site as, which has no traffic and despite some advertising doesn’t appear to function. And as you can see by their Semrush traffic chart, they weren’t around for long:
