Does anyone know if this is the same. domain.com and domain.com.au are they both considered to be .com domains. I think that they would but not 100%
I don't think so, since you can have absolutely different sites on those URLs. It would be interesting to see the actual algo on this one I tried with my site (I have .com ) and I know for a fact that there is .co.uk one that I don't own and I tried to search on google.co.uk for my keywords..... .co.uk site was nowhere to be found and my .com show up right away.
