If you’ve had websites that have been affected by the past or ongoing Panda and Penguin updates then you really should check out this May webmasters update from Matt Cutts about SEO for Google and the Penguin 2.0 (v2) update.

Although he does mention that things can change and maybe take it with a grain of salt anyone who’s interested in achieving good search engine rankings needs to keep up to date with ongoing changes.

Remember it’s not always the best idea to rely on just one source of traffic such as from natural search and SEO. There are so many ways available to get visitors to your website that diversification is quite easy really and could actually help your rankings when you include social media and visitor interaction.
