If you're experiencing no changes in your domain authority in Moz Pro, there are several steps you can take to potentially address the issue. Firstly, focus on actively building high-quality backlinks to your website, as domain authority heavily depends on the quality and quantity of these links. Additionally, stay updated with Moz Pro's algorithm changes, as updates can impact how domain authority is calculated. If you've recently made significant changes to your backlink profile, be patient, as it may take time for these updates to reflect in your domain authority score. Lastly, cross-check your backlink profile using other reputable tools to ensure consistency in data, and if technical issues persist, reach out to Moz Pro support or your website developer for assistance. These steps can help ensure your domain authority is accurately measured and reflects your site's true SEO strength.
