Comment on Fresh Content SEO Tutorial by Susanne.

Does Google Prefer Fresh Content? How does the new Penguin work with the Stallion Responsive I am using? Are there things I need to do like NOT add ‘nofollow’ links to ALL outbound affiliate links on my site?

And, how do I know if you site has taken a hit in the Google rankings? Is this easy to see somewhere?

In the Stallion Responsive you talk a lot about Panda Buster but I have not seen mention of Penguin. What are the differences?
