How does Google Crawl Multi-Regional Sites?

[lemonz]

I've been reading up on this on Webmaster Tools but just wanted to see if anyone could explain it a bit better.

I have a website which is going live soon which is going to be set up to redirect to a localised URL based on the IP address i.e. NZ IP ranges will go to .co.nz, Aus IP addresses would go to .com.au and then USA or other non-specified IP addresses will go to the .com address.

There is a single CMS installation for the website.

Does this impact the way in which Google is able to search the site? Will all domains be crawled or just one?

Any help would be great - thanks!

Forgetting all other issues, I am assuming you are using a PHP redirect to accomplish this and that you have three sites: .co.nz, .co.au, and .com which you are using the geo targeting preference for US.

Given that you have three sites, they will be indexed individually based on all the normal ways a site is indexed. So, links to site A will bring a googlebot. Sitemap of site B will bring same. Etc. If you are using some type of cross domain canonical or have any redirects of one site to the other for any reason, they will be followed across as well.

All domains will be crawled independent of one another. So, you need to get links to each.

Best,
