I've built a website at a new domain for a client and want to completely remove the old site so Google isn't seeing any duplicate content and they will have a completely fresh start.
In Cpanel on the old site I've setup a wild card redirect for the root to point to the new website which I thought would cover things so that any page on the old site would redirect to the new domain. However, sub pages found on Google aren't being redirected to the new site but just getting a 404 error which has baffled me.
Not great on server config stuff so any advice would be appreciated. the old site was Wordpress in case that's relevant.
Many thanks in advance
