Domain Authority (DA), a metric invented by Moz in order to anticipate how well a website would rank on search engine results pages.
The DA scale goes from 0 to 100. A better chance of appearing highly on the SERPs is correlated with higher scores. Low ratings suggest that your page might not rank highly in the SERPs.
There is neither a good score nor a poor score in DA because it is a relative ranking. Simply put, a "good" DA is one that outranks your rivals, while a "poor" DA is one that underranks them.
To determine what constitutes a high domain authority, you must look at a website's score on a scale of 1 to 100, with 100 representing the highest possible score.
There's always opportunity for advancement, and if you don't work on it, your website will probably drop in the rankings.
Website Authority (PA) is a score that has been devised to forecast how well a certain page will rank on search engine result pages (SERP). Values for Page Authority vary from one to 100, with higher scores indicating a better ability to rank.
The higher the number, the more likely the search engine results page (SERP) would be better. Moz's Page Authority search engine ranking score ranges from 1 to 100. The SEO tool considers both the amount and quality of links that a webpage receives while defining this measure.
In short; a page will be more likely to get a higher score if it contains backlinks from authoritative pages, such as Google, Wikipedia, official government pages, well-known newspapers or magazines.
You should take the below scores into account to rate a website's domain and page authority,
The metrics DA and PA are quite similar. However, a DA score forecasts the overall performance of a domain in the SERPs, but a PA score forecasts the performance of a given webpage.
In addition, whereas Page Authority completely disregards on-page SEO factors like keyword use and content optimization, Domain Authority places a stronger focus on them.
When utilized in tandem, these two rankings may provide a wealth of knowledge about the SEO of your site and page.
