I have a WordPress powered site which ranks very well on Google (
example.com). Half a year a go I started a side project at a subdomain (
subdomain.example.com) although it is indexed by google, it doesn't rank very well. The side project has become the main project now so I want to replace
My question is: How can I make this switch without affecting the SEO ranking?
subdomain.example.com so the old pages will remain indexed and help me with the ranking.
