I have been thinking over the last few days on ways to diversify my marketing, both targeting specific sectors as well as brand awareness. While I  sat there I came up with quite a number of ideas, including:

Brand awareness:
PR
Sponsoring a roundabout / charity event
Local exhibitions
Newsletters
SEO
Networking
Advertising in the paper / magazines
Sign's on my car
Flyering
Public speaking

Targeted:
Direct mail / calling
Targeted Pay Per Click campaigns

Out of all of these I have probably tried 4 already - not many is it? So, as horrible as clichés are, I am going to extend my marketing mix a little further. But I thought I would see what everyone else is doing, and what successes they have had with their marketing, and how they have done it.

So really I want to know:

1. What is the best piece of marketing you have done?
2. What else would you recommend to the rather short list of marketing ideas above?
