OK first of let me disclaim this post by saying I am totally against black hat SEO and the contents of this post is purely my opinion based on my understanding of how businesses in general function.
So – the title says Google needs black hat SEO. Explain…
I admit I am one of those people who go onto blogs and criticise Google for not penalising sites for using black hat SEO techniques and particularly for not policing their own rules – but, the more I think about it the more I realise that Google needs to leave some black seo alone (as in not penalise them individually) in order to further develop their algorythms.
Think of it this way – it the Google police shut down every black hat site it found then their web spam team would have nothing to test new algorythms on – effectively they would lose their R&D department!
So as I see it Google will continue to allow a fair whack of small offenders and then will address the problem in new algorythms. And that means we will always be fighting against the black hats.
Ho hum – I suppose it is the way of the world.
