SES London Conference
I am very surprised to hear so many SEO companies throwing in the towel after Google's penguin update in April 2012. The general feeling amongst the experts is that Google has defeated SEO companies. I don't agree!
It is certainly harder to produce good SEO results based on old, outdated techniques. You just need to shift gear and move to the new era of SEO. Multi-channel marketing, good contents and visitor-oriented site delivery are the keys now. There will still be the reward of appearing on the first page of Google if all is done well.
The big question is: how many SEO companies can deliver what they promise. A question that only time will tell.
