1. One of my most important sites is one about a specific product, the site is available in different languages (example: mysite.com/de for German). In May (around the so-called May Day) the German version of my site suddenly was unfindable in Google.de when searching for the name of the product promoted on my site. The other language versions still did great though. In July I started building more backlinks and added new language versions to the site. I also changed the language meta attributes since I thought Google could have been confused with the new languages. Then suddenly traffic fell completely; Google is still updating its cache of my site. But when I enter some of the content on my site in Google, it doesn't show my site in its results. All my content is unique, most links come from clean sources. 2. A new webstore I just launched in multiple languages had a domain parking page a few months. Now the homepage is showing a white PR logo (which means that it should be in Google) and inner pages are indexed. However, when I lookup the ocntent of these innerpages in Google, again I don't see my site appearing... This site hasn't seen any search engine traffic yet and has been online for about two weeks. What do you people think? Just a temporary thing or should I be worried?
