There has been a very long delay in the forthcoming Penguin Update ( Oct 4th 2013 ) since then site owners that cleaned up their sites have been languishing in a Penguin hell, Spam queries are running rampant and the Negative SEO industry has taken hold, hell there is even Extortion going on.
When 3.0 is released, this could be another animal altogether.
Hi, Tim Capper here, SEO expert and general web entrepreneur. I loved Google Plus from day one, I decided to create the guide GooglePlus-One.co.uk. We update the site as often as possible, we try and create easy to follow guides for different Google Plus features and of course we provide Plus One votes, should you require a little top up.
