Google Algorithms and SEO

Everyone wants to know about Google's Algorithm(s) and their secrets.... and I think it could come down to an algorithm as small as this one (but heh I am no mathematician!)

Targeted Meta Data + Targeted (Resourceful) Content + Accessibility = £££ (or $$$)

Thats the simplest formula I can give. I am missing one component of this algorithm... have you guessed what it is yet?
