Recommendations for a network of student-related content

Question

I am running a network of websites with notes, homeworks, essays, etc. where users share their own content. I'm having real trouble with the latest Google updates (penguin, panda, etc) because the content is mainly poor-quality and with the same topic. For that reason, I want to create more websites and have more probabilites to appear in the SERPs.

My question is: does Google analyzes related websites in order to exclude it from the results? I've think about distribute the websites around the world, in different hostings, but I'm afraid that Google would link it by their analytics, webmaster tools or adsense account, is that possible? What other recommendations do you have?

Answer 1

Yes, it is possible.

Google has developed very powerful tools to establish associations between domains for the purpose of spam detection1.

So if you're worried about new projects being viewed negatively by association, it may be advisable to take steps to avoid it, such as using separate email addresses, analytics accounts and domain hosting.
