This guide to online marketing is short and worth reading. However, I don't think you can take everything in the write-up as gospel. For example, I would definitely agree with New Rules #1:

Technology is changing the way you reach customers and the way that customers find you.

and #4:

Static Web Sites and Stale Content are effectively DEAD

But, #10 is pretty ridiculous:

Keyword Clouds and Tag Clouds are Essential

Useful maybe. But essential?? No way.
