Home has DA 50 but Subpages have Page Authority of 1

[brainfruit]

Hello,

we already asked this, but there was no answer. We would be happy for any information.

How could it be, that our subpages all have a PA 1 if the home got DA 50?

technical specialities:

• Megamenue opens on click only
• Category pages dont exist (home/i-do-not-exist-as-page-category/PA-1-subpage)
• All subpages have a high amount of links to ressources (over 200)
• subpages are crawled and online for some time

what would be the most obvious cause for the low PA? Would the external link profile be the main reason?

thanks in advance. I would be happy to answer your questions

Hi there

There's a difference between domain and page authority, as you may already know:

Domain Authority is a score (on a 100-point scale) developed by Moz that predicts how well a website will rank on search engines. Use Domain Authority when comparing one site to another or tracking the “strength” of your website over time. We calculate this metric by combining all of our other link metrics—linking root domains, number of total links, MozRank, MozTrust, etc.—into a single score.

Page Authority is a score (on a 100-point scale) developed by Moz that predicts how well a specific page will rank on search engines. It is based off data from the Mozscape web index and includes link counts, MozRank, MozTrust, and dozens of other factors.

The difference?

Whereas Page Authority measures the predictive ranking strength of a single page, Domain Authority measures the strength of entire domains or subdomains. The same is true for metrics such as MozRank and MozTrust.

Domain authority takes in account the entire domain link backlink profile, it's the essentially the sum of all it's pages (links and all). Page authority is strictly that page by itself (links and all). To increase your page authority, you should make sure you are following SEO best practices and your backlink profile is topically relevant and authoritative. This is a hard metric to improve at the page level, but this is the most direct way to effect this metric. I would suggest doing a backlink audit and building a backlink strategy that focuses on relevancy.

I hope this answer your questions, let me know if it doesnt! Good luck!
Patrick
