What is Domain Rating?

Why It Matters

Domain Rating gives teams a quick, consistent way to track link-building progress and benchmark against competitors inside the Ahrefs ecosystem specifically. It matters most as a trend line over time within one tool, since jumps or drops usually correspond to real changes in a site's referring domain profile, like a wave of new high-quality links or the loss of a major one. Because it doesn't map one-to-one onto Moz's Domain Authority, mixing the two scores in the same report or comparison creates confusion rather than clarity. Ignoring which tool a competitor's reported score came from can lead a team to misjudge how hard a market actually is to compete in. Used consistently, though, it's a solid proxy for whether link-building investment is paying off.

Example

A site shows a Domain Rating of 45 in Ahrefs and a Domain Authority of 38 in Moz at the same time, two different numbers describing a similar underlying concept from two different tools with different backlink indexes and algorithms. Because of that mismatch, teams that track link-building progress typically pick one tool's score to monitor consistently over time rather than comparing Domain Rating and Domain Authority directly against each other as if they were the same metric.

Frequently Asked Questions

• Can Domain Rating be compared directly to Domain Authority?

  No. Even though both scores run 0 to 100 and estimate backlink strength, they come from different crawl indexes and different proprietary algorithms, so the same site will usually show two different numbers that aren't meant to be equated.

• What data does Domain Rating rely on?

  It's based primarily on the number and quality of referring domains linking to a site, weighted by those linking domains' own authority, similar in spirit to how Domain Authority works but computed with Ahrefs' own methodology and link index.

• Is a higher Domain Rating always better?

  Generally yes for competitive strength, but it should be read alongside actual organic traffic and rankings. A site can have a high Domain Rating from old or low-relevance links while still underperforming competitors with fewer but more relevant links.

• How often is Domain Rating updated?

  Ahrefs recalculates it as it recrawls the web and refreshes its backlink index, which happens frequently, so the score reflects a fairly recent snapshot rather than a static, rarely-updated figure.

• What's the best way to raise Domain Rating?

  Earning backlinks from a wider set of high-authority, relevant referring domains is the primary driver, since the score weights both the number of unique linking domains and their own strength rather than total link count alone.
