Welcome to the Q&A Forum

Hi Allen, So you have your .com.au that is set to target Australia and you want a .com which will have the same content and will target some other country? All you need to do is implement the rel="alternate" hreflang="x" tags - http://support.google.com/webmasters/bin/answer.py?hl=en&answer=189077 If you implement those tags your sites will not experience duplicate content issues. Implementing the Rel=canonical will result in only one of our sites ranking, with the rel="alternate" hreflang="x" tags both your sites have a chance to rank in the respective countries. Thanks, Carlos
