What do search engines think about subdomains in respect to my main domain?

Search engines generally treat subdomains as separate entities from the main domain, but they are still associated with it. Here’s what search engines typically consider: 1. Separate Ranking: Subdomains are often seen as independent websites, meaning they may have their own rankings, authority, and SEO efforts. However, they still benefit from being part of the main domain if the main domain has strong authority. 2. Link Equity: Links from the main domain to the subdomain don’t pass as much link equity as links from one page to another within the same domain. This means you might not fully benefit from the main domain’s authority, although Google and other search engines sometimes treat subdomains as part of the overall site. 3. Content Relevance: Search engines look at whether the content on the subdomain is relevant to the content on the main domain. If the subdomain serves a very different purpose (e.g., a blog on one subdomain and a store on another), search engines might treat them separately in terms of SEO but will still consider the relevance of both domains in the context of your overall web presence. 4. SEO Efforts: It’s important to manage SEO for subdomains just like you would for the main domain. You’ll need to optimize each one individually (e.g., on-page SEO, backlinks, technical SEO) to improve its search engine ranking. 5. User Experience and Structure: A well-organized site structure, with clear subdomains dedicated to specific content, can sometimes be more user-friendly, which indirectly impacts SEO. A disorganized structure or irrelevant subdomains can harm your SEO efforts. In summary, while subdomains can help organize content or services separately from the main site, their SEO performance will depend on how they are managed and how search engines interpret the relationship with the main domain. It’s important to treat them as individual entities and optimize them accordingly.
