[Typo3] Google dropped content from subsites

[Fabian Langheim]

Hi,

a question to the searchengine-wizards here:
We've got a site which was fully indexed up until the last google-run:
http://energiering.ifact.de

After the last update of the google index, on all subsites, the content is
no longer indexed. Previously, every tiny bit of text could be found. The
only thing we changed over time was adding more content.

Have any of you an idea why the content is no longer indexed?

kind regards
Fabian
