Domain Authority (DA) is a metric developed by Moz that indicates the strength and authority of a website on a scale from 1 to 100. It is calculated based on various factors, including the number and quality of backlinks pointing to the domain.
If your domain authority has not changed, it could be due to several reasons:
Limited time: Domain Authority updates are not frequent, and it may take some time before you see any changes. Moz updates their index periodically, so you might need to wait for the next update to see any potential changes in your domain authority.
Stable backlink profile: If your website's backlink profile has remained relatively constant over time, with no significant increase or decrease in the number and quality of backlinks, your domain authority may not show much change.
Competitor changes: Sometimes, your domain authority might not change, but your competitors' domain authority may have also remained stable, maintaining the relative position between websites.
