Free Backlink Authority Checker & Analyzer

Perform a complete website backlink analysis. See how many referring domains a site has, check backlinks anchor text, and discover its true authority strength.

Quick Summary: A backlink checker analyzes links from other websites to yours. Backlinks are Google's #1 ranking factor. Use this free tool to check your backlinks score, estimate trust scores, and uncover the link profile of any competitor.

How to Perform a Website Backlink Analysis

To perform a website backlink analysis, enter the root domain into the search box and click "Check Backlinks." Our tool queries the OpenPageRank API to fetch the latest referring domains, Domain Authority, and a sample of the anchor text used instantly.

  1. Enter the Domain: Type the root domain you want to analyze (e.g., ahrefs.com) into the input box.
  2. Click Check: Press the "Check Backlinks" button to run the site backlink analysis.
  3. Analyze Results: Review the Domain Authority gauge, the number of unique referring domains, and check backlinks anchor text in the table.

What Do These Backlink Metrics Mean?

Our tool provides three main types of data: Domain Authority (DA), referring domains, and an estimated Trust Score.

Backlinks Score (Domain Authority)

A metric created by Moz that predicts how well a site will rank. It ranges from 1 to 100. Higher is better.

Referring Domains

The number of unique websites linking to the target site. If 50 different websites link to you, you have 50 referring domains. This is more important than total backlinks.

Check Backlinks Anchor Text & Trust Score

Anchor text is the clickable text in a link. Trust score indicates how safe and authoritative your link profile is. Links from high-trust sites pass more value than links from spammy sites.

Why Backlink Authority is Crucial for SEO

Search engines like Google use backlinks as "votes of confidence." When a reputable website links to yours, it signals that your content is valuable and trustworthy. The more high-quality backlinks you have, the higher your backlink authority checker score will be, and the higher your site will rank.

How to Get More Referring Domains

Building a strong backlink profile takes time. The most effective strategies include guest posting on reputable blogs, creating linkable assets (like infographics or original research), and fixing broken links on other websites (broken link building).

Beware of Toxic Backlinks

Not all links are good. Links from spammy, low-quality sites (PBNs, link farms) can harm your rankings. If your Trust Score is low, you may need to use Google's Disavow Tool to ignore those toxic links. This is why a regular backlink analysis is so important.

Our Data Source & Methodology

We use the OpenPageRank API (powered by Common Crawl) to estimate Domain Authority and referring domains. This is one of the most reliable free data sources available.

Limitations: Because accessing billions of real-time links costs a lot of money, our free tool uses a smart estimate for "Total Backlinks" and "Anchor Texts". For exact data, premium tools like Ahrefs or Semrush are required.
