What is Domain Rating (DR)?

Domain Rating is Ahrefs' proprietary metric that measures the strength of a website's backlink profile on a logarithmic scale from 0 to 100. A site with DR 80 has not just twice the backlinks of a DR 40 site — the logarithmic scale means DR 80 represents an exponentially stronger profile.

Ahrefs updates DR weekly. The score is calculated based on the number of unique domains linking to the target, weighted by the DR of those linking domains. A single link from a DR 90 site moves the needle more than 100 links from DR 20 sites.

DR vs. DA — What's the difference?

Neither DR nor DA is a direct Google ranking factor — Google uses its own internal link graph. However, both metrics correlate strongly with organic performance because domains with strong backlink profiles tend to rank well.

How to use DR for link building

DR is most useful as a quick filter at the top of a link-building workflow. It tells you whether a site is worth a closer look — before you invest time in a full outreach sequence.

Qualifying outreach prospects

When building a target list, set a DR floor (e.g. DR 30+) to filter out brand-new or low-authority sites. Paste your entire prospecting list here and export the results to a spreadsheet. Sort by DR descending and prioritise the top tier. A DR 60 prospect from a relevant niche is worth more than ten DR 15 sites in the same vertical.

Evaluating expired and dropped domains

Expired domain auctions regularly surface domains with DR 30–60 and aged backlink profiles. Paste the shortlist into this tool before bidding. DR alone doesn't confirm link quality — also check the referring domain count and relevance — but it eliminates the obvious junk quickly.

Vetting guest post opportunities

Guest post marketplaces often list sites with inflated or faked metrics. Cross-check every opportunity here. A site selling guest posts at DR 50 that shows DR 12 in this tool (which uses the official Ahrefs API) is misrepresenting its authority.

Competitive link-gap analysis

Paste your top organic competitors and compare their DR. A competitor consistently ranking above you at a lower DR suggests their on-page or topical authority compensates for a weaker link profile — meaning content and structure improvements may outperform a link acquisition campaign.

Frequently Asked Questions

How often is Domain Rating updated?

Ahrefs updates Domain Rating weekly. If you checked recently in the Ahrefs dashboard, scores here should match — both use the same official public API endpoint.

Can I check more than 20 domains?

The anonymous limit is 20 domains per check. Sign up free to check up to 50 at once. Your check history will also be saved to your account so you can track DR changes over time.

Is this the same DR as in Ahrefs?

Yes. SERP.tools calls the official Ahrefs public API — the same data source the Ahrefs dashboard uses. The scores are not estimated or computed by a third-party algorithm.

What is a good Domain Rating?

DR 50+ is a strong, established site whose links carry real SEO value. DR 70+ is authority-level — typically major publications, established SaaS brands, or high-traffic niche sites. DR 30–49 is the mid-range where most active link-building targets sit.

Why does my DR look different from what I see in Ahrefs?

DR updates weekly. If you checked in the Ahrefs dashboard more than a week ago the scores may differ by a point or two. Scores should match within the same weekly cycle. Note that Ahrefs may round differently in their UI.

Does a high DR guarantee rankings?

No. DR measures backlink profile strength — it does not account for content quality, on-page optimisation, Core Web Vitals, or topical authority. It is a useful signal in a link prospecting workflow, not a ranking prediction.
