The only thing we did recently was 301 some old urls ( same domain) to the new stucture. Funnily enough these are now a cached but the important landing pages with lots of links (not 301'd are) not. We lost serps in 17 languages now :(
Any ideas?
All I can say is maybe remove the 301's if that's all you've done. It could also be an issue with you being another victim of this Bourbon update.
According to my investigation, Google was thinking that there was some sort of duplicate content despite the different languages. I added a meta description tag for each page, and the problem disappeared. It seemed that adding a unique description in the local language for each page was enough evidence for Google that each page was different.
After adding the descriptions all pages were fully indexed within 2 weeks.
Are you saying you never had the "description" meta tag and you added them, or you had them then changed their text?
I first added more links to the missing pages to increase PR because I thought that could be the reason, but that didn't help. Then I read some posts on this forum that descriptions might be a reason for Google to decide what is duplicate content. Since some months Google is showing the description of a page in the SERPs for many search queries, so it seems that the description tag has gained value for Google. I decided to add a description for all the problematic pages and they all were cached within two weeks.
I am now adding descriptions to all other pages, just to be sure this type of problem won't happen again. Adding a good description also increases the number of users that visit the site from Google, so the work will eventually be paid for.
