Understood. Thanks for the response @ms and @hamidreza

hello best practice is domain.com/blog

If you want to leverage your domain authority, use /blog.

If you want to separate it, use subdomain.

Subdomain basically means different domain, while /blog is part of the domain.

Whatever works for you.

Can any one please guide me what is the best approach to host a blog on corporate website?

Either

Mydomain.com/blog

or

blog.mydomain.com
