Domain Authority — is DA or DR important?

Domain Authority (DA or DR) is a metric developed by Moz that predicts how well a website will rank on search engine result pages (SERPs). It scores websites on a scale from 1 to 100, with higher scores indicating a greater likelihood of ranking well.

Moz says on it’s website:
“Domain Authority and its page-level equivalent Page Authority – DA and PA – are two of the best-known and most respected metrics in the SEO industry, widely used to rate a domain or page’s rankability.”

Google Denys it even exists.

What is interesting is Google has repeatedly stated that they neither contributed to its development, nor use it, nor consider it a ranking signal — but is that true?

It has been reported in 2020 that Google’s John Mueller stated:

“Just to be clear, Google doesn’t use Domain Authority *at all* when it comes to Search crawling, indexing, or ranking.”

But, in recent information leak from Google, there us is an entry called SiteAuthority score.

DA Domain Authority SiteAuthority

Is Google being honest about it’s ranking signals? To be honest I would think it makes total sense for Google to hide what it uses to rank pages to prevent artificial manipulation of rankings on Google’s search results.

Safety in Numbers.

To add validity to DA we can see Moz is not the only company that uses DA, other key tools used in the industry utilize a form of the domain authority metrics to assess the strength and ranking potential of websites. Some of the notable ones include:

  1. Ahrefs:
    • Domain Rating (DR): Ahrefs’ DR measures the strength of a website’s backlink profile on a scale from 0 to 100. It predicts a domain’s ability to rank in search engines based on the quality and quantity of its backlinks.
  2. SEMrush:
    • Authority Score: SEMrush’s Authority Score is a compound metric that evaluates the overall quality and SEO performance of a domain. It considers factors like domain age, backlink profile, and organic search traffic.
  3. Majestic:
    • Trust Flow (TF) and Citation Flow (CF): Majestic uses these two metrics to evaluate the quality (TF) and quantity (CF) of a website’s backlinks. Trust Flow focuses on the trustworthiness of linking sites, while Citation Flow measures the link volume.
  4. Ubersuggest:
    • Domain Score: Ubersuggest provides a domain score that reflects the overall authority of a website based on its backlink profile and other SEO factors.
  5. SERPstat:
    • Domain Rank: SERPstat’s Domain Rank assesses the overall authority of a domain, taking into account its backlink profile, domain age, and other relevant SEO metrics.

Each of these tools has its own proprietary algorithms and methodologies for calculating these metrics, but they all aim to provide a similar insight into a website’s potential to rank well in search engine results.

So, given the amount of attention and confidence these top industry leaders apply to this metric it is unlikely that DA is not a contributor to good SEO practice. A good SEO strategy while being aware of DA, it remains limited in it’s role and requires a comprehensive strategy inclusive of other metrics.

Limitations of Domain Authority.

Although your DA can provide insights into the success of your SEO strategy and the health of your backlink profile, over-focusing on DA can divert attention from other critical SEO activities. It’s a useful metric, but not the only one that matters, because of it’s broad measurement which does not account for keyword-specific ranking factors or search intent nuances.

Balancing DA with Other Metrics:

  • Page Authority (PA): This metric, also from Moz, predicts the likelihood of a single page ranking well. It can be more precise for specific page optimization.
  • Traffic and Engagement: Metrics like organic traffic, bounce rate, and conversion rate are direct indicators of SEO success.
  • Content Quality: High-quality, relevant content aligned with user intent often results in better rankings.
  • Technical SEO: Ensuring your website is technically sound, with good site speed, mobile-friendliness, and proper indexing, is crucial for overall SEO health.


Slow and Steady Wins the Race.

While Domain Authority is an important and useful metric for understanding and improving your website’s SEO potential, it should be used in conjunction with other SEO metrics and strategies. A holistic approach that considers content quality, user experience, and technical SEO will yield the best results in improving search engine rankings and overall online presence.

Instead of creating content for the sake of ranking and keyword manipulation, creation of content that is both informative and well written is the best strategy. DR and DA will naturally increase with your site’s performance from good content, organic traffic and natural links from your audience.
