Why are my pages not indexed in my google-language search

Hi,

I`m running a german website/vBulletin forum and I wonder why the google international search:
site:www.wunderkessel.de - Google-Suche
(63.500)

delivers far more results than the search limited to german sites:
site:www.wunderkessel.de - Google-Suche
(231 results)

Is there something wrong with the language settings in the header/head parts of my pages?

Thank you - all the best,
Sacha

No, you domain name extension and language setting in the Header of your page all accordingly points to being of German origin. Perhaps you need to improve upon the number of .de related websites of which you have a running link exchange with?

Hello Sacha,

you can also try adding Content-Language meta tag to your pages:

HTML Code:

<meta http-equiv="Content-Language" content="de">
