Enter up to 20 Links (Each Links must be on separate line)
You must also be thinking that. Many website owners ask this question to know the ideal number, There is no exact number for page authority, It depends on the nice market, In some niche markets PA 30 may be enough to rank on top of google and in some highly competitive niches maybe PA 50 score is less. but there is a practice you can follow to know the best PA score in any niche. List down all of your first page competitors, check the page authority of all of them, scroll down to their results, and calculate the average score of all the results.
This will give you the idea of how strong does your page stands out and how much more effort should you put into SEO. The higher the page authority score the more is the capacity of a particular page to rank in search engine results, especially Google.
