Will Reducing Number of Low Page Authority Page Increase Domain Authority?

[Kingalan1]

Our commercial real estate site (www.nyc-officespace-leader.com) contains about 800 URLs. Since 2012 the domain authority has dropped from 35 to about 20. Ranking and traffic dropped significantly since then.

The site has about 791 URLs. Many are set to noindex. A large percentage of these pages have a Moz page authority of only "1". It is puzzling that some pages that have similar content to "1" page rank pages rank much better, in some cases "15". If we remove or consolidate the poorly ranked pages will the overall page authority and ranking of the site improve?

Would taking the following steps help?:

1. Remove or consolidate poorly ranking unnecessary URLs?
2. Update content on poorly ranking URLs that are important?
3. Create internal text links (as opposed to links from menus) to critical pages?

A MOZ crawl of our site's URLs is visible at the link below. I am wondering if the structure of the site is just not optimized for ranking and what can be done to improve it. THANKS.

In my opinion, these metrics are not intended for this type of use.

I would stop looking at these metrics and get to looking at how you can improve the total quality of your website.  Google doesn't give a darn about your page authority or domain authority.

Would taking the following steps help?:
1. Remove or consolidate poorly ranking unnecessary URLs?
2. Update content on poorly ranking URLs that are important?
3. Create internal text links (as opposed to links from menus) to critical pages?

Everyone who owns a website should do these things.  So, Yes!  Do them!

The Page Authority of 1 basically means that the pages don't have any links from any external source and that the only links that are pointing towards them are probably from your own internal pages that also don't have a ton of links from external sources.

I wouldn't worry in itself too much about a decrease in Domain Authority. A change from 35 to 20 is nothing in the end if you take into account that the web is growing and that Moz indexes since 2012 have grown as well. So relatively speaking it's logical that your ranking would always decrease with that as well. I would focus on building great links first and getting a bigger audience before I'd start worrying around internal link structures.
