How to check DA and PA of a website

To check Moz Domain Authority (DA) and Page Authority (PA), use Moz or a provider that explicitly supplies Moz data. DA applies to a domain; PA applies to an individual page. Our homepage SEO review checks search basics and performance instead; it does not calculate DA or PA.

A practical comparison

1. Choose a specific search and the page on your site that should answer it.
2. Note a few relevant competing pages in the same market. Use the exact page URL for page-level metrics and the domain for domain-level metrics.
3. Use the same provider and date for each comparison. Check whether the tool reports a page or domain metric, and avoid comparing numbers from different vendors as if they were interchangeable.
4. Inspect the actual results: does your page address the query clearly, offer useful evidence and link to related information? Use Search Console to check indexing, impressions and queries for your own site.

What to do with the result

Treat a score as a prompt for investigation, not a target or a diagnosis. An unexplained drop can reflect a provider’s data or methodology. Review relevant links and page quality; do not buy links or disavow them solely to move a metric.
