I've bought a domain (as an example, hello.com) on which I have set up a wordpress blog. By default I have decided to block Google and all other search engines until I complete my site. While working on something else I have decided to make around 5 backlinks for hello.com while it was still blocking search engines. Today, I googled the domain without the extension and to my surprise it's indexed as "www.hello.com/". Is it because of the backlinks? I mean, it must be because how else would it be indexed, but how is this possible?
