Domain Authority (DA) is a score developed by Moz that predicts how well a website will rank on search engines. The score ranges from 1 to 100, where higher numbers mean a better chance of appearing at the top of search results. In simple terms, the stronger your DA, the more likely your website is to rank higher on Google and other search engines.

• Backlink Quality – More high-quality, authoritative links improve DA.
