Sub-domain related concern

How a sub-domain can help to a website ?

Is it more effective to use www.blog.example.com instead of using www.example.com/blog/ ?

It affect the SEO of a website or not?

Thanks

It’s maybe better for mega-blogs with endless topics. For a small-medium blog, it’s better to put the blog inside your main domain (Anyway no official answer by Google. Its depends on the case). Its one more tactic of SEO.

Technical

From a technical aspect, it’s harder to follow two sites (Two google analytics/console keys) - on webflow its two projects (Ping Pong). More difficult to maintain.

Thanks… Really, these blogs helps to clear all the concern about subdomain…
