Domain Rating Checker

Check any website's Ahrefs Domain Rating (DR) score instantly. Powered by the official Ahrefs public API. No signup, no API key, completely free.

Quick answer: Domain Rating is a 0-100 score from Ahrefs that reflects how strong a site's backlink profile is relative to every other crawled site. It is logarithmic, so a DR 60 site has far more link authority than a DR 30 site, not just twice as much. Use it to qualify link prospects, benchmark competitors, and track your own link-building progress over time.

How Ahrefs Calculates Domain Rating

Ahrefs has published the methodology directly. DR is calculated in three steps. First, Ahrefs counts the number of unique referring domains pointing to the target website. Second, it factors in the DR of each of those referring domains. A link from a DR 80 site contributes more than a link from a DR 15 site. Third, it calculates how many unique domains each linking site links out to. A site that links to 5 sites passes more per-link value than a site that links to 500.

The result is compressed onto a 0-100 logarithmic scale and recalculated across all sites in the Ahrefs index simultaneously. This means your DR can drop even if you have not lost any backlinks, simply because other sites in the index have grown faster than yours. That is not a penalty; it is how the relative scale works.

Using DR to Qualify Link Prospects

The most practical use of DR is screening link prospects before you invest time in outreach. Here is a simple qualification filter that works well for most niches:

Why DR Can Drop Without Losing Backlinks

This confuses a lot of people. Your DR dropped by 3 points last month but you did not lose any links. How is that possible? Because DR is a relative score. When thousands of other sites in the Ahrefs index build links faster than you, the overall curve shifts and your position on it can slide backward even if your raw link count grew.

Two legitimate reasons for a real DR drop: losing high-DR referring domains (check Ahrefs for "Lost" in the referring domains report), or one of your main linking sites losing its own DR sharply. A site that linked to you at DR 55 and dropped to DR 12 is now contributing much less to your score than it was. Neither of these is cause for panic, but both are worth investigating before assuming a manual penalty or algorithm issue.

DR vs. Other Domain Authority Metrics

Every major SEO tool has its own domain authority metric. They correlate broadly but are not interchangeable. A prospect outreach team quoting DA 40 is not the same as DR 40. Here is how the main ones compare:

How to Use Bulk DR Checks for Competitor Research

The bulk check tab above handles up to 20 domains at once. Here are three workflows where this is useful:

1. SERP competitor benchmarking. Take the top 10 results for your target keyword. Paste all 10 domains into the bulk checker. Export the CSV. You now have a DR benchmark for the competitive set. If the median is DR 45 and you are DR 15, you know how big the gap is before content alone can carry you.
2. Guest post list screening. Export a list of prospects from any database. Paste the domains into bulk check. Filter out anything below your threshold before spending time verifying pitches. This alone cuts prospecting time significantly.
3. Link exchange audit. If someone proposes a link swap, check both sites with the bulk tool. If their DR is lower than yours by more than 20 points, the exchange favors them more than you. Use the data to decide or counter-propose a different arrangement.

What DR Cannot Tell You

DR measures one thing: how strong a domain's backlink profile looks in Ahrefs' index. It says nothing about organic traffic (a DR 60 site with all links from unindexed directories can have zero traffic), content quality, topical authority, or spam history. A site can buy links from high-DR sites and inflate DR without earning it. Always cross-reference DR with actual traffic data and a quick manual look at the linking domains before making decisions based on the number alone.

Single Check vs. Bulk Check: When to Use Each

Use Single Check when you want a quick read on one domain: a link prospect that just landed in your inbox, a site you are about to write for, or your own domain to confirm recent progress. Type or paste the domain (with or without https://), click Check DR, and the result appears with a visual gauge and plain-English strength label.

Use Bulk Check when you have a list: SERP competitors, a batch of outreach prospects, or a group of sites you want to benchmark. Paste up to 20 domains, one per line. The tool checks them sequentially with a short delay between requests to stay within the Ahrefs public API rate limit. When done, export the full table as CSV for your spreadsheet or CRM.

Data is pulled directly from the Ahrefs free public API on each request. No caching, no stored results. The public API is rate-limited per IP. If you hit the limit, wait a few minutes and try again.
