Hi, do you know how backlinks from domain affects subdomains and is it better to focus on backlinking domain or particular subdomain?

Short answer: backlinks help the exact host and URL they point to, so build links to whatever URL you actually want to rank. The distinction matters more for strategy than for a single algorithmic rule.

As @canardefred implied, internal linking and site architecture determine how much authority travels between hosts. Search Console treats subdomains differently unless you use a domain property, so a subdomain can behave like a separate site for management and reporting (). That means links to example.com do not automatically make blog.example.com rank — unless you intentionally pass authority via cross-links, navigation, sitemaps, or redirects.

Practical checklist:

  • Decide architecture up front: if content is closely related, prefer a subfolder to concentrate link equity; if it needs isolation (different product, business unit, or geo), a subdomain can be justified. See data and discussion on tradeoffs ().
  • Build backlinks to the target asset. For main brand or top-level keywords, homepage links help; for deep pages or long-tail terms, get links directly to those pages.
  • Connect hosts deliberately: use persistent site-wide navigation links, XML sitemaps, and occasional contextual links from the root to the subdomain to share authority.
  • If moving content between subdomain and folder, implement 301 redirects and update sitemaps so search engines follow the move (follow Google’s site-move guidance).

Monitor results with Search Console and a backlink tool, and prioritize content quality and relevancy over domain-name tricks. If there is confusion in replies above, the right takeaway is: target backlinks to the URL you need to rank, and choose architecture that matches business and maintenance needs rather than assuming domain-level links will automatically lift all subdomains.

let me see ... that's a good question ... it sat here for 12 days unanswered ... I'll take a stab at it ... Ok. I have an answer.

It depends.

It depends on what you may ask.

Well ... this to me is not really about domains or sub-domains at all, but of an indecision to determine which web page is more important to you. I would think the rule of thumb here would be to better and more frequently internally link the one you deem more important.

The keywords in the domain have a high weight. As if any site or blog has the similar keyword in its domain then it is possibility that it obtains highly searched by the users.

Hi,

In my own experiences, majority of back links should be linked to domains since we usually rank big volume main keywords using our home page. Of course, deep linking would be very helpful for ranking long tail keywords purpose.

all the best,

In my opinion optimising sub domains is much more difficult as it is treated as a new site, so optimising any new site takes more time.
