 I know that both are very important for our site, DA will give an overall value because it is valued based on the domain we use, whereas PA is only judged from the page itself and in one site will have different PA this depends on how the page popularity that.

Domain Authority (DA) is one of the most important metrics when it comes to websites. Developed by Moz, the DA is a reflection of how popular and trustworthy a site is. The higher the DA, the better the link.

Page Authority (PA) is a score developed by Moz that predicts how well a specific page will rank on search engine result pages (SERP). Page Authority scores range from one to 100, with higher scores corresponding to a greater ability to rank.
