The SEO space is always changing and it’s important to know which metrics matter and impact your website on Google Search and which do not. Spam Score, Domain Authority (DA) and Domain Rating (DR) are metrics that are often discussed in the SEO space. However, in this blog article, we are going to be looking at these metrics, and providing evidence to show that these metrics are not part of Google’s ranking system.
Understanding Spam Score
Spam Score is a metric invented by Moz to measure the chances of any particular site being penalized by Google because of spam associated characteristics. This starts with analyzing 27 signals commonly found in penalized sites. However, it is important to note that Google has confirmed it does not use Spam Score in its ranking algorithm. “Google does not use any scores from third-party SEO tools or services,” Google Search Advocate John Mueller said. “It doesn’t matter whether it is about a website’s authority or a rating about spamminess, Google does not use any of these scores.”

Domain Authority (DA) and Domain Rating (DR): Neither Are Google Ranking Factors
Moz’s Domain Authority (DA) and Ahrefs’ Domain Rating (DR) are metrics that effectively predict how well a website will score with search engines. These scores can be based on a myriad of factors, including the total number of links as well as the quality of the pages linking to it. Nevertheless, there is ample documentation stating that Google does not include DA or DR metrics in any of their search ranking algorithms. John Mueller has even clarified many times that “Google doesn’t use Domain Authority at all”

Page Authority (PA): Another Third-Party Metric
Page Authority (PA) is a metric developed by Moz to estimate the likelihood of a specific page ranking well in search engine results. It’s based on data from Moz’s own web index, considering link counts, MozRank, MozTrust, and other factors.
While PA can be helpful for internal SEO analysis or competitor comparison, it’s important to recognize that it is not a ranking factor used by Google. Google does not reference Moz’s metrics in its algorithm, and relying on PA to measure your true SEO success can be misleading.
As Google’s John Mueller has repeatedly stated, Google doesn’t use any third-party authority metrics such as PA or DA.
These metrics are still useful (but not for ranking)
While these metrics don’t directly influence Google’s rankings, they can still provide valuable insights:
Spam Score: Identifies potential issues that could result in penalties.
DA, PA and DR: Helpful in measuring the “strength” of a website’s backlink profile compared to others.
Although these are third-party metrics, they shouldn’t be the only metrics. As Google states, “It’s just an SEO myth that won’t die.
In conclusion, although Spam Score, Domain Authority, Page Authority and Domain Rating are common metrics used in the SEO world, they are not part of Google’s ranking algorithm, and focusing on these metrics can detract from effective SEO activity. For practical and effective SEO, focus on creating strong content, earning natural backlinks, and a great user experience.
