Hey group, I have a question about subdomains vs subfolders. i hope this is the correct channel. I'm working on a site with 30,000+ pages, and multiple stakeholders that have, at times, acted somewhat autonomously . In the past, they've worked with vendors that would just spin up subdomains for a number of reasons (ad campaign landing pages, blogs, etc.). Now, in some cases, they are working well (some ignored, others getting good traffic, etc.). We thought the over-reliance on subdomains was just to make things easier on the vendor for their tracking and get around any internal requirements from our end. However, when asked, we were told that because of the large number of pages, this would help some blog content get found and crawled more easily. I know there's no set rule for one or the other, but I've seen numerous studies showing that subfolders work better for SEO, and comments from Google saying while they don't care either way it "makes sense" to keep related content together on the main domain. SO, my question is: Is the number of pages a common reason to split otherwise related blog-type content onto a subdomain? Would this be something best left alone, or would migration over to the main domain ever be considered? Thanks!
