Welcome to the Q&A Forum

Hey there! Thanks for reaching out to us! In simple terms, Domain Authority is our best prediction about how content would perform in search engine rankings on one site vs. another. Page Authority answers the same question for an individual page, each page can be different therefore they could have different scores. Both are amalgamations of all the link metrics we have combined into a single, predictive score. Feel free to reach out to help@moz.com if you have any specific questions,
