Q: We're moving our blog from blog.site.com to site.com/blog — is that worth the migration risk?

Thoughtful question — there's a real tradeoff here, not just dogma.

Short answer: usually yes, it tends to help, but it IS a migration and deserves the full process.

Long answer: Google treats a subdomain as a somewhat separate site, so a subfolder often shares authority with the main domain more smoothly. Many sites see the blog and money pages reinforce each other better in a subfolder. But moving blog.site.com/post to site.com/blog/post is a domain-pattern change — every old URL needs a 301, internal links must update, and you'll see the usual temporary wobble.

Don't do it casually mid-quarter. Treat it as a planned move with a redirect map.

Next step: crawl the subdomain, map each post to its subfolder URL, 301 them, update internal links and the sitemap, and watch recovery over 4 to 6 weeks before judging the result.
