im reading this piece about saas seo audits and it basically calls out how most agencies just spam lists of small stuff like broken links or missing meta descriptions that dont even matter much. they separate the real heavy lifting from the 'maintenance' junk which is way more important. specifically that whole debate about hosting blogs on a subdomain vs a subfolder. supposedly
subfolder hosting is the only way to actually see results in traffic and rankings. also mentions how server-side rendering vs client-side rendering is one of those
structural decisions that stays broken for years if you get it wrong. i dont know if i buy the subdomain thing being such a massive killer every single time but moving a whole blog later sounds like a nightmare for engineering.
