Backlink Metrics Explained

Referring Domains

Number of unique domains linking to your site. Quality over quantity — 100 links from 100 different domains is far more valuable than 100 links from 1 domain.

Domain Authority (DA)

Moz's 1-100 score predicting how well a domain ranks in search engines. Higher is better, but compare it to competitor scores rather than in isolation.

Domain Rating (DR)

Ahrefs' version of authority score. Reflects the strength of a website's backlink profile relative to all other sites in their index.

Anchor Text

The clickable text in a hyperlink. Diversify your anchor text profile — too many exact-match anchors can look manipulative to Google.

Follow vs Nofollow

Follow links pass ranking authority ('link juice') to your site. Nofollow links don't directly pass authority but can still drive referral traffic.

Toxic Score

Estimates whether a backlink could harm your rankings. Links from spammy or irrelevant sites can be disavowed via Google Search Console.

About Backlink Checker

The Backlink Checker reveals the external websites linking to any domain or specific URL, along with key metrics like domain authority, anchor text, and link type. Understanding your backlink profile is essential for building authority, identifying toxic links, and discovering new link-building opportunities. SEO professionals, digital marketers, and website owners use it to monitor their off-page SEO health and track competitor strategies.

Key Features

  • Displays total backlink count, referring domains, and unique IP addresses
  • Shows anchor text distribution to detect over-optimized or spammy patterns
  • Classifies links as dofollow, nofollow, sponsored, or UGC for accurate analysis
  • Domain authority and page authority scores for each referring source
  • New and lost backlink tracking to monitor link profile changes over time
  • Exportable backlink report in CSV format for further analysis in spreadsheets

How to Use Backlink Checker

  1. 1

    Enter the domain or URL

    Type the root domain to see sitewide backlinks, or enter a specific page URL to analyze backlinks pointing to that individual page.

  2. 2

    Review the backlink summary

    Check the overview panel for total backlinks, referring domains, and the ratio of dofollow to nofollow links to assess overall profile strength.

  3. 3

    Analyze referring domains

    Sort by domain authority to identify your most valuable backlinks, and look for patterns in the types of sites linking to you.

  4. 4

    Check anchor text distribution

    Review the anchor text breakdown to ensure a natural mix of branded, generic, and keyword-rich anchors. Heavily keyword-stuffed anchors can signal manipulation to search engines.

  5. 5

    Export and take action

    Download the full report and use it to disavow toxic links, reach out for broken link reclamation, or identify competitors' link sources for outreach opportunities.

Common Use Cases

Competitor link analysis

Check where your competitors earn their backlinks to discover high-authority websites that might also be willing to link to your content.

Toxic link identification

Find spammy, low-quality, or irrelevant backlinks that could trigger a Google penalty, then create a disavow file to submit through Search Console.

Link-building campaign tracking

Monitor new backlinks acquired each month to measure the effectiveness of your outreach campaigns and guest posting efforts.

Broken link reclamation

Identify referring pages that link to your 404 pages, then set up redirects or contact the linking site to update the URL and recover lost link equity.

Why Use Our Backlink Checker

Enterprise backlink tools like Ahrefs and Moz charge steep monthly fees for link data. This free checker gives you referring domains, anchor text distribution, dofollow/nofollow classification, and authority scores without a subscription. Analyze your own site or spy on competitors' link profiles instantly, and export results to CSV for deeper analysis.

Link Research Kept Off the Radar

The domains you investigate and backlink reports you generate are never associated with your identity or shared publicly. Your competitor research, link-building targets, and disavow lists remain private, ensuring your off-page SEO strategy is never exposed to rivals.

Frequently Asked Questions

What is a referring domain versus a backlink?
A referring domain is a unique website that links to you, while backlinks count every individual link. One referring domain can produce multiple backlinks if it links to you from several pages. Referring domain count is generally a stronger authority signal.
Are nofollow backlinks worthless?
Nofollow links do not pass PageRank directly, but they still drive referral traffic and contribute to a natural link profile. Google has also stated it treats nofollow as a hint rather than a strict directive, meaning some SEO value may still transfer.
How often should I check my backlink profile?
Monthly checks are sufficient for most websites. If you are running active link-building campaigns or have experienced a ranking drop, weekly monitoring helps you respond quickly to new toxic links or lost valuable backlinks.
