I would like to host two copies of same website under different domains. The idea is to setup one for testing and other for production. So will it cause SEO or duplicate content issue?
As far I know indexing can be disable by the following tag
So is it safe to deploy testing version site with noindex tag?
Because I doubt's even if indexing is disabled, still google can read the content. So later will lead to rejection of Google adsense due to duplicate content ?
And please suggest the best method to achieve this?
(I don't have adsense now, but I may apply for it later)
