I'm in the process of adding various languages to my existing site. After a bit of research on how to best structure it I'm now wondering how it may affect the potential for acheving the famous Sitelinks-enabled listing.
So, the structure choices are 1. subdomain and 2. subdirectory.
Subdomain in G-bot's eyes is a completely new site.
Subdirectory is an extension of the existing site.
I'll use Google.de for this example:
I've seen a poker site that's using the subdomain method (de.domain.com) and they have Sitelinks in google.de for their main term.
Would it be possible to get Sitelinks on Google.de if the site was structured using subdirectories instead? eg. domain.com/de/
I've never seen an example of a multilingual site using subdirectories and getting the Sitelinks listing in country-specific Google results. My concern is that the site may lack authority potential for that country if it's simply a site extension.
Can anyone shed any light or confirm any sightings that it's possible?
