I have a website with a navigation in different languages (language can be switched) and content that was submitted by users in almost any language. And I'll register many many domainendings for my businessname.
So, do I now redirect (by 301) all of them to the .com domain. Or do I redirect not by 301, instead pointing my countryspecific domains to the countryspecific version of the website, that serves the website in the langeuage of that country and point every other domain (not countryspecific) to the version with the english navigation.
First approach would built massive pagerank by backlinks, because 301d pass all pagerank to the redirected site (I got that info out of Matt Cutts videos). But I heared a .com domain has a pretty hard time to show up on top in lets say german search result of google.de, even tough it serves also german content.
Second approach: Every domain would not have so much pagerank, but I heared that Google takes countryspecific TLDs as a huge ranking boost, if you are searching eg. from google.de then most likely .de domains will show up higher in the search results.
I guess nobody can know what's better, because nobody know the algorithm of google, but anyway please give me your feedback.
