What Exactly is Domain Authority (DA)?

Domain Authority is a search engine ranking score developed by Moz that predicts how likely a website is to rank in search engine result pages (SERPs). It's based on data from our Link Explorer web index and uses dozens of factors in its calculations.

3 Surprising Truths About DA

It's Logarithmic

Going from 30 to 40 is significantly harder than going from 10 to 20.

It's Relative

DA is a comparative metric, meaning you should judge it against direct competitors.

It's Not a Google Factor

While highly correlated, Google doesn't use this score directly in their algorithm.

How Can I Increase My Score?

Boosting your DA isn't about "gaming the system." It's about becoming a better, more authoritative website in the eyes of the internet. Here's how:

Audit Your Link Profile: Remove any low-quality, spammy links that might be dragging your site down.
Build Quality "Seed" Links: Focus on getting links from industry leaders, national news sites, and EDU/GOV domains.
Improve Internal Linking: Ensure your link juice is flowing correctly from high-authority pages to newer content.
Create Linkable Assets: Publish original research, helpful tools, or infographics that people want to link to.

Domain Authority FAQs

Why did my DA drop for no reason? ↓

Because DA is a relative scale, if a high-authority site like Wikipedia gains millions of links, the whole scale recalibrates, potentially lowering your score even if you didn't lose links.

Does social media shares help DA? ↓

Directly, no. However, more social shares mean more visibility, which often leads to more natural backlinks, which will increase your DA.
