Backlinks to less important subdomain

[RCF]

We have two subdomains on our site: blogs and *www. Our most important and competitive pages are on the www subdomain. I have some pages on the blogs subdomain that have valuable backlinks. Would it be helpful to our SEO efforts for the www subdomain to move and redirect those pages on the blogs subdomain to the www subdomain?

Hi there,

My opinion? Go for a subdirectory. Move all the content from blog.domain.com to www.domain.com/blog/. Always remember to set everything correct in the migration.

There are many believers that state thar having the complete site in the same subdomain improves the overall performance.
There has been many discussions about this topic, ending up with an offical video from Google:
Subdomain or subfolder, which is better for SEO? - Google Webmasters

Ideally, absolutely. But I'm not sure I can get buy-in for moving the whole blog right now, which is why I'm considering moving just a couple of pages, if it would be worthwhile.

I dont believe that moving just a couple of pages can make a difference.
Remember that the "power" that you want to transfer, is through the root domain. So I´d move the whole blog so as working once and the whole site is benefited

Best luck.

Hello!

I don't think it would be beneficial to worry about moving just a few pages. Instead, do what you can to link back over to relevant pages on the main site from those blog pages, and try to drive users to the main site if appropriate. Google will also look at traffic patterns in addition to links and pass more value from the blog pages to your main site if they see user behavior as such.
