Welcome to the Q&A Forum

I recently launched a site - http://www.footballtriviaquestions.co.uk and the site uses Paypal. In order to test the PayPal functionality I set up a zapto.org domain via a permanent IP service that points directly to the computer I've written the website on. It appears that Google has now indexed the zapto.org website. Will this cause problems to my main website, as the zapto.org website will pretty much contain content that is an exact duplicate of what is held on the main website. I've looked in Google webmaster tools for the main website and it doesn't mention any duplicate content, but I'm currently not in the top 50 ranking for "football trivia questions' on Google despite SEOMoz ranking my home page with an A rating. The page does rank at position 16 in Yahoo and Bing. This seems odd to me, although I do have very few back links pointing to my site. If the duplicate content is likely to be causing me problems  what would be the best way to knock the zapto.org results out of Google
