I've built a festival website that has a different theme each year. There's a main domain: festival.com and each year is on a subdomain: 2015.festival.com. This is the first time we are using the subdomains so the main domain has all of the festival content on it from last year. We will be reusing many of those pages on the new site.
What I've done so far is a 302 (temporary redirect) to subdomain. I do notice that the old site pages are still showing up in Google, so we've got a popup directing folks to the new site. I'm assuming that if I create pages on the subdomain with exact same URL's as main site, then those pages on the subdomain will start showing up on Google. Is this correct?
In addition to this, do I need to add "NO INDEX" to the main domain pages so that the subdomain pages can take precedence in Google?
This is all a bit hazy for me. So thanks for any help!
