Local results vs non-local results

Hi

Let's say that I have a site in German on a .de domain targeting some keywords which is also targeted by sites in English on .com, .net etc..
If a person from Germany then searches for that keyword, would my German speaking site in theory rank higher based on the fact that it is a local result rather than an "international"?

Cheers..

And does it make a difference if users are using google.de or google.com ?

Really? No one? Is this to noobish of a question or does nobody know?

I know less about ranking ccTLDs, but technically your ccTLD should be able to outrank the other sites for users in Germany assuming your on-page, off-page, and local SEO tactics let Google know that your page is the most appropriate one to display.

The user's browser language, location, and Google domain (Google.de) all play a role in that algorithm; although if I remember correctly, the user's location is more important than the browser language and preferred domain. As for if the domain matters, I think as long as the user is in Germany, the SERPs will look similar on Google.com and Google.de for them.

There's also a local SEO subforum here that you can post in next time you have a question about local SEO.
