I think if you have some analytical skills with knowledge of ppc, email marketing then you can stay in the industry means you should have some additional skills
Well I think there may be a re think on SEO work. As the economic climate factors cut in, more companies will realise that if they are not in the top 5, don't bother. So I feel some SEO companies will grow, but many will falter!
I think SEO alone is hard to survive.. I would prefer like this.. SEO + Marketing + Socializing = Success That means SEO should be combined by other factors to succeed
