My answer to Can you share your best marketing campaign?
Answer by Ken Larson:
I set up a Google blog as an extension of my volunteer work that blossomed into a web site ($10 a year to buy and convert it from a blog to a domain in my name) containing the basics of entering and succeeding in the small business government contracting venue as well my books and articles on the subject for download via Box Net.
The idea was to refer clients to article links at the site to avoid repeating myself over and over and keep myself available for specific inquiries and problems.
I linked everything together and began answering questions as well as registering at many of the free applications for networking web sites on the Internet to see how that could benefit my work.
Twitter, BlogCatalog, Facebook, Widgetbox, Empire Avenue, Pinterest, About Me, Quora and similar free applications have served my site well.
The Adsense Feature added cash flow. Roughly 30% of my clients began coming via networking. The result has been heavy traffic, good efficiency in supporting in excess of 7000 counseling cases over the last 11 years and virtually no expense to me as a volunteer working for a non-profit organization.
