What is a Good Domain Rating

Definition

A good Domain Rating (DR) — Ahrefs' proprietary metric for measuring a website's backlink profile strength on a 0-100 scale — depends on your industry and competition, but generally a DR of 40-50 is solid for most businesses, 50-60 is strong, and 60+ indicates an authoritative site. Domain Rating measures the relative strength of a website's backlink profile compared to all other sites in the Ahrefs database. It is a logarithmic scale, meaning moving from DR 30 to DR 40 requires significantly less effort than moving from DR 70 to DR 80. DR is widely used in SEO for benchmarking, competitive analysis, and link prospecting.

Why It Matters

Domain Rating provides a quick, standardized way to assess a website's backlink authority relative to competitors and potential link partners. For B2B SaaS companies building organic growth strategies, understanding where their DR stands compared to the sites ranking for target keywords helps calibrate expectations and prioritize efforts.

If the top-ranking pages for a target keyword belong to sites with DR 70-80 and the company's site has a DR of 25, competing for that keyword through content alone will be an uphill battle. The gap indicates that link building must be a significant component of the SEO strategy before those rankings become achievable. Conversely, finding keywords where top-ranking sites have DRs in the 30-40 range represents a more realistic opportunity.

DR also matters for link building outreach. When evaluating whether to pursue a backlink from a potential partner site, DR serves as one signal (among several) of the link's potential value. A link from a DR 60 site generally passes more equity than a link from a DR 15 site — though relevance, traffic, and placement context also matter.

It is important to understand that DR measures backlink profile strength, not overall site quality or search rankings. A site can have a high DR and low traffic if its backlinks come from irrelevant sources. Similarly, a niche B2B SaaS site with a DR of 35 can outrank a DR 70 site for specific long-tail keywords if its content and on-page optimization are superior. DR is one input in a multi-factor evaluation, not a definitive score.

How It Works

Domain Rating is calculated using Ahrefs' proprietary algorithm based on the backlink profiles of indexed websites. The key mechanics include:

Backlink quantity and quality — DR considers how many unique domains link to a website (referring domains) and the DR of those linking domains. A site with 500 referring domains from DR 50+ sites will have a higher DR than a site with 500 referring domains from DR 10 sites.
Logarithmic scale — The 0-100 scale is logarithmic, which means each incremental point requires exponentially more backlink authority to achieve. Moving from DR 10 to DR 20 might require acquiring links from 50 new referring domains. Moving from DR 60 to DR 70 might require links from thousands of new high-authority domains.
Relative measurement — DR is relative to all other sites in the Ahrefs database. As the database grows and the overall backlink landscape shifts, a site's DR can fluctuate even without changes to its own backlink profile. This means DR should be tracked as a trend over time rather than obsessed over as a daily metric.

For B2B SaaS companies, realistic DR benchmarks by stage look roughly like this:

DR 0-20 — New or very early-stage sites with minimal backlink profiles. Typical of recently launched SaaS companies.
DR 20-40 — Sites that have begun earning backlinks through content marketing, PR, and partnerships. Many growing SaaS companies operate in this range.
DR 40-60 — Established sites with meaningful backlink profiles. Companies in this range can compete for moderately competitive keywords and are taken seriously in link prospecting.
DR 60-80 — Authoritative domains with strong backlink profiles. These are typically well-funded SaaS companies, major industry publications, or companies with years of content investment.
DR 80+ — Elite authority sites like major tech platforms, news organizations, and household-name SaaS brands.

The most productive use of DR is comparative: benchmarking against direct competitors, evaluating link prospects, and tracking progress over time. Chasing a specific DR number without connecting it to keyword rankings and traffic outcomes leads to misallocated effort.
