Will output go down?

Question

Google

There is a mini blog on wp(ex.com)
And a separate service on the site (ex.com/service/)
If you delete all wp content and leave it to issue 404 to bots or replace
it with 403/444 his keywords?
They do not match with the blog on vp

Answer 1

если ссылки из блога на /service/ были - выдача поменяется

Answer 2

It is advisable to save all URLs that led to the /service page. Since during internal linking, your pages also transfer weight to each other, and this weight is taken into account by the PS when ranking pages.
