Understanding Domain Authority and Page Authority Metrics
Domain Authority predicts how well a website will perform in search results using a scale from 1 to 100. Moz computes these ratings by evaluating multiple factors including linking root domains, complete link tally, and other search engine metrics. The stronger the DA score, the more likely that domain is to perform strongly.
PA works in the same way but focuses on individual pages rather than complete sites. A individual URL might have more elevated page metrics than the domain's overall DA if it has gained authoritative references or social engagement.
What this really means is that DA and PA give you a picture of a site's SEO strength. However, these metrics aren't foolproof indicators of search performance. They're evaluation aids that work best when you're comparing different domains against each other.
The scores get revised often as Moz's algorithm processes updated metrics. Don't get concerned if you see fluctuations - they're expected and often show alterations in the SEO ecosystem rather than issues on your domain.
