Domain Authority (DA) is a metric developed by Moz that predicts a website's ranking potential on search engines. When your domain authority has not changed, several factors could be at play:
Consistency: If your website's performance, content quality, and backlink profile remain consistent, your DA may not change significantly over time.
Competitive Landscape: Changes in the DA of other websites in your niche can also influence your own DA. If competitors improve their metrics, your relative position may remain stable.
Algorithm Updates: Search engine algorithms constantly evolve. Lack of changes in your DA could be due to stability in the algorithm or minimal impact from recent updates.
