I just deleted my entire website and prevented robots from crawling your my in robots.txt. I'm going to publish the same pages under a different domain. Should I have to wait until Google has deindexed old pages from its index (duplicate content issue) or is it safely to publish a new website with same old content now today? I don't want to use 301-redirects. Thanks.
I think a 301 redirection would be really helpful in your situation because it would help in transferring your seo efforts for the old domain to the new domain.
