When to use Page Authority
Page Authority is essential when focusing on the optimization of individual pages for specific keywords. For example, if you're launching a new blog post or product page, analyzing its Page Authority can help you gauge its potential to rank. It is particularly useful for on-page SEO strategies, such as improving content quality, internal linking, and keyword targeting.

While Domain Authority gives insight into the overall strength of a domain, Page Authority allows for a more granular analysis of individual pages. They often overlap, as a higher Domain Authority can positively influence the Page Authority of its individual pages, but they serve different purposes in SEO strategy.
