I have a client that have a site: https://www.example.com. He has a blog on an another provider with a subdomain: https://blog.example.com.
The SEO on the two is divided, so I'm wondering what is the better solution to correct this issue.
We cannot bring the blog on the same server than the site.
So we though of something, changing https://blog.example.com to https://www.example.com/blog.
How can this be achieved, knowing that the blog and the site will not be on the same server?
I have a DNS CNAME record in mind, but is this SEO significant?
