I bought an
example.org domain and created an account on a free web host. When signing up, I was forced to choose a 3rd level domain name for my site. Then I was allowed to specify my 2nd level domain name. Now
example.org is under my hosting account waiting for the nameservers to take effect, but my 3rd level domain is already functioning. I put an
index.html on it, and it shows as expected.
There is a good chance that I will not be able to delete that 3rd level domain at all and will have the two mirror sites as shown below:
May this lead to Google penalizing my 2nd level domain for content duplication?
