What Is Domain Rating?
Domain Rating (DR) is a metric developed by Ahrefs to quantify the overall strength of a website's backlink profile. The score runs from 0 to 100 on a logarithmic scale, so moving from DR 10 to DR 20 is relatively straightforward, while moving from DR 60 to DR 70 requires a substantially larger and higher-quality body of referring domains.
DR is calculated primarily by looking at how many unique websites link to your domain and how strong those linking domains themselves are. A single link from a DR 80 publication like a major South African news outlet carries far more weight than fifty links from low-DR directories or link farms. Ahrefs updates the metric regularly as it discovers new backlinks through its crawler.
It is important to understand that DR is a third-party metric, not an official Google signal. Google does not use DR directly when ranking pages. However, sites with high DR scores tend to rank well because strong backlink profiles are a genuine ranking signal for Google. DR gives SEO professionals a fast, standardised way to benchmark a site's link authority against competitors without having direct access to Google's internal data.
DR should not be confused with Moz's Domain Authority (DA) or Semrush's Authority Score. All three attempt to measure similar concepts but use different data sets and methodologies. For Ahrefs users, DR is the primary domain-level authority benchmark, while Page Authority (called URL Rating in Ahrefs) applies at the individual page level.
Domain Rating In Practice
A Pretoria-based law firm starting its SEO journey might launch with a DR of 2 or 3, reflecting very few inbound links. After a year of consistent link building through local directories, press mentions, and digital PR, that firm might reach DR 20 to 25. This increase typically corresponds with measurable improvements in keyword rankings for terms like "Pretoria attorney" or "Gauteng legal services."
When auditing competitors, South African SEO practitioners will often pull the DR of each competing domain in Ahrefs Site Explorer to understand how much link authority they need to build to compete. If your site sits at DR 18 and your top competitor is at DR 45, you know that content quality alone will rarely be enough to outrank them for competitive terms. You need a structured off-page strategy to close that gap over time.
DR is also a useful filter when assessing potential backlink opportunities. A guest posting opportunity on a DR 35 industry publication in South Africa will generally deliver more sustained ranking benefit than ten placements on DR 5 blogs. Looking at DR alongside traffic and relevance helps prioritise link acquisition efforts for the best return on investment.
What Domain Rating is
Domain Rating (DR) is a third-party SEO metric, developed by the tool provider Ahrefs, that scores the strength of a website's backlink profile on a scale from 0 to 100, based largely on the quantity and quality of other sites linking to it. A higher Domain Rating indicates a stronger, more authoritative backlink profile relative to other sites, while a lower DR indicates a weaker one. Domain Rating is one of several competing third-party authority metrics, alongside Moz's Domain Authority and others, that different SEO tools use to summarise a site's link-based authority in a single comparable number. It is important to understand that Domain Rating is not a Google metric and does not directly affect Google rankings, Google does not use DR, and it is a tool's own estimate, calculated on that tool's own index of the web and its own model. Its value is as a convenient, comparative gauge: it lets you compare the relative backlink strength of sites (your own versus competitors, or potential link partners), track whether your backlink profile is growing stronger over time, and get a rough sense of a site's authority. Domain Rating matters as a widely-used shorthand for backlink strength in SEO analysis and link-building, provided it is understood as a third-party estimate of link authority rather than an official or ranking-determining score.
Using Domain Rating sensibly
Domain Rating is useful when treated as a comparative, directional indicator of backlink strength rather than a target to chase or a definitive measure of SEO success. Sensible uses include benchmarking your site against competitors to gauge relative link authority, assessing potential link sources or partners (a link from a higher-DR, relevant, reputable site generally carries more weight), and tracking your own DR over time to see whether your backlink profile is strengthening. Its limitations, though, must be kept in mind. Because DR reflects backlinks specifically, and only as measured on one tool's index, it does not capture content quality, relevance, user experience or the many other factors in actual rankings, so a site can have a high DR yet rank poorly for lack of relevant content, or a modest DR yet rank well through strong, relevant content and good SEO. DR also should not be pursued as an end in itself: chasing a higher number through low-quality or manipulative links is counterproductive, since it is genuine, relevant, authoritative links, and overall SEO quality, that drive real rankings, with DR merely reflecting part of that. Different tools give different authority scores for the same site, so DR is not an absolute truth. For a South African business, DR is a helpful shorthand for comparing backlink strength and tracking link-building progress, but it should inform, not dominate, SEO decisions, which are better guided by earning quality links and building genuinely good, relevant content than by fixating on a third-party number.
FAQ
What is a good Domain Rating for a South African business website?
For most South African SMEs, a Domain Rating between 20 and 40 is reasonable and competitive. Large local publishers and established brands typically sit between 50 and 70. A DR above 70 is considered strong even in competitive global niches.
Is Domain Rating the same as Domain Authority?
No. Domain Rating is Ahrefs' metric while Domain Authority is Moz's equivalent score. Both measure backlink profile strength but use different algorithms and data sets, so scores are not directly comparable between the two tools.
