What Is DR in SEO

In SEO, “DR” stands for Domain Rating. It is a metric developed by the SEO tool Ahrefs to measure the strength and authority of a website’s backlink profile on a scale from 0 to 100. The DR score is a reflection of the quantity and quality of backlinks pointing to a domain, which can influence its ability to rank higher in search engine results pages (SERPs).

Calculation of DR: How to Calculate Domain Rating 

Ahrefs calculates Domain Rating using a proprietary algorithm that assesses the strength of a website’s backlink profile. While the exact details of the algorithm are proprietary and not publicly disclosed, the general process involves several key factors:

  1. Backlink Quantity: The total number of unique domains linking to the target website. This is also known as “referring domains.”
  2. Backlink Quality: The strength of the referring domains themselves, measured by their own Domain Ratings. High-quality backlinks from authoritative websites contribute more to the DR than those from less authoritative sites.
  3. Ahrefs Rank: The relative ranking of the target website within Ahrefs’ database. Websites with more high-quality backlinks are ranked higher.

Here’s a basic overview of the process:

Step-by-Step Outline:

  1. Collect Data: Gather data on all the unique domains that link to the target website.
  2. Assess Quality: Evaluate the quality of these linking domains using their own DR scores.
  3. Aggregate Influence: Sum up the influence of these backlinks. Higher DR scores of referring domains have more impact.
  4. Scale Normalisation: Apply a logarithmic scale to ensure the DR score fits within the 0-100 range. This scale helps differentiate between the scores, particularly at the higher end of the spectrum.

Simplified Example:

  1. Identify Referring Domains: Suppose your website has backlinks from 10 different domains.
  2. Check DR of Referring Domains: Each referring domain has its own DR score. For example:
    • Domain A: DR 90
    • Domain B: DR 75
    • Domain C: DR 60
    • (and so on)
  3. Weight the Influence: Domains with higher DR scores contribute more to your DR.
  4. Calculate Aggregate Score: Sum the weighted scores of all referring domains.
  5. Normalize the Score: Apply a logarithmic function to bring the aggregate score to a 0-100 scale.

Important Considerations:

  • Link Profile Diversity: Having a diverse backlink profile with links from many different domains is generally better than having many links from the same domain.
  • Diminishing Returns: Additional links from the same domain have less impact on the DR than the first link from a new domain.
  • Constant Updates: DR is updated regularly as new links are discovered and existing links are evaluated for quality.


To track and calculate DR, you need to use the Ahrefs platform, which provides detailed reports on backlinks and the corresponding DR scores for websites.

In summary, while the exact calculation of DR is proprietary to Ahrefs, understanding the general principles of backlink quantity and quality, as well as the logarithmic scaling applied to these factors, gives you a clear idea of how DR reflects the strength and authority of a website’s backlink profile.
