"The successful approaches I know about always seem to include a focus on conversion optimization rather than traditional SEO methods. Focusing on the user experience with a strong value-add for the visitor seems to make a big difference."
Thank you for pointing this out. My take on Penguin is that this change in the algorithm was about educating the respective website owner to get busy focusing on their visitors with content development, usability and conversion testing. I've always encouraged the idea of working on this as the core objective then adding a bit of SEO in the mix.
This makes sense to me as Google is working to improve the usability of the web experience and has to battle so much spam on a daily basis..(and there's a ton of it in the index still...just saw an egregious example the other day...).
Big challenges for site / business owners these days but a necessary evolution in the process. And don't forget the Social side with Google. This takes real time and energy to engage with the tools (G+, Youtube...etc...)
