Hi... I'm working on a site, based in China, with a Chinese domain, .com.cn.

The sites main target, is the western market, so, google.com.

Does the fact that this is a .com.cn, make it more difficult to rank on google.com?

Does it's Chinese IP address also factor?

It's 8 years old, and pretty established.

If I was to design a new site... and use a .com... what's the best way to keep it's current authority... I know it's something to do with a 405 redirect... or is it 301?

Cheers
