Domain Authority: A score predicting a website's likelihood to rank well in search engines

Domain Authority (DA) is a score developed by Moz that predicts the likelihood of a website ranking well in search engine results pages (SERPs). It's important to note that it's not a ranking factor itself, but rather an indicator of a website's overall SEO strength.

Here's a breakdown of its meaning:

The score:

  • Ranges from 1 to 100, with higher scores indicating a higher likelihood of ranking well.
  • Mostly used for comparison purposes rather than absolute values.

What it considers:

  • Links: Backlinks from high-quality websites are a major factor, as they demonstrate trust and authority.
  • Domain age: Established domains generally have an advantage.
  • On-page optimization: Content quality, technical factors, and user experience play a role.
  • Website size: Larger websites often have more content and links, but quality matters more than quantity.

What it doesn't consider:

  • Specific keywords: DA reflects overall SEO strength, not specific keyword rankings.
  • Freshness of content: While important, freshness isn't directly factored into DA.
  • Social media activity: Social media isn't directly involved in DA, although it can indirectly influence ranking factors.

Limitations of DA:

  • Not a ranking factor: While it might suggest ranking potential, it doesn't guarantee good rankings.
  • Doesn't consider niche: Comparing DA across different industries might not be meaningful.
  • Focuses on backlinks: While important, backlinks aren't the only ranking factor.


  • DA is a valuable tool for comparing websites and gauging overall SEO health.
  • Focus on building a strong SEO foundation with diverse ranking factors, not just chasing a high DA score.
  • Don't rely solely on DA for predicting rankings; use it as part of a broader SEO strategy.
