In a new Google Webmaster Central blog post, John Mueller of Google Explains how Google handles the new top level domains (TLDs). The reasoning behind why they are publishing this information is due to the fact that there are questions and misconceptions that they’ve been hearing throughout the webmaster community.
The long and short of it is, there aren’t any TLDs that are preferential over others, at least in Google’s eyes. Basically, they are all treated equally and rankings.
In actuality, the only real difference between all TLDs are the geo-specific TLDs that Google will default to a specific country and use them as an indicator that the website is more important than a specific geographical region.
Google has published some FAQs on the topic today. You can find them by following the link I provided below that will lead you to a post written by Barry Schwartz. Check it out!
