Online marketing is changing
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.
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.
