Google's 7 principles of marketing

1. Result must be trackable


2. Promote trial


3. Let others speak for you


4. Data. Not hype.


5. You’re smart. And your time matters.


6. We’re serious. Except when we’re not.


7. Big ideas move us.

I think this is very useful stuff and I'd love to see these principles implemented wherever I'll work in the future.
My personal favourites are 1. Result must be trackable (you can't believe how many times not tackling this point upfront will give you headaches) and 3. Let others speak for you (maybe I'm wrong but this seems to imply the basic understanding that brands are conversations and that having others to speak about you will bring much more credibility in what is being said).
