Possible to Improve Domain Authority By Improving Content on Low Page Rank Pages?

[Kingalan1]

My sites domain authority is only 23. The home page has a page authority of 32. My site consists of about 400 pages. The topic of the site is commercial real estate (I am a real estate broker). A number of the sites we compete against have a domain authority of 30-40.

Would our overall domain authority improved if we re-wrote the content for several hundred of pages that had the lowest page authority (say 12-15)?  Is the overall domain authority derived by an average of the page authority of each page on a domain? Alternatively could we increase domain authority by setting the pages with the lowest page authority to "no index".

By the way our domain is www.nyc-officespace-leader.com

Thanks, Alan

Hi Alan

First - don't noindex pages to increase your authority numbers. That's not going to help. Especially if those pages do hold value. You need to give your site an honest and unbiased assessment.

I would take a look at the following:

Page Authority

I would read the following to see if your content can be cleaned up or enhanced: How To Do a Content Audit - Step-by-Step

I would read this to get a good competitive analysis going:
The Illustrated SEO Competitive Analysis Workflow

I would read the following to see if you can clean up any backlink related issues:
Link Audit Guide for Effective Link Removals & Risk Mitigation

The reason being - these authority numbers are pretty holistic and not just content related. You have to look at multiple facets to increase these numbers - it takes a lot of honest research and critiques of your site to make sure these numbers increase. They aren't related to one specific aspect of your site.

I would also take a look at the on-site SEO factors to make sure you have all the foundational aspects taken care of. Here's a great technical checklist as well.

Hope these all help! There's a lot of angles to look at - good luck!
