All I can do is rave about the book World Wide Rave: Creating Triggers that Get Millions of People to Spread Your Ideas and Share Your Stories, by David Meerman Scott. If you want to drive thousands or millions of people to your business, web site, or blog, Scott shows the way to do it in a clear, very-easy-to-understand way, using numerous real life examples.
The best thing about his techniques is that they are free, and involves no advertising or public relations assistance, which he says are totally unnecessary. The most important section is the Rules of the Rave, where he describes the six most important things to remember when creating a rave, and are later described in detail throughout the book.
He touches on why it is important to give away something from free, and that means totally free, no registration, no login, no request for email address, no nothing. The freebie can be anything from a web app to an e-book to music.
The word-of-mouth (or word-of-email or word-of-blog) connections can be geometric, at no cost and very little work.
Anyone who has a website or business or book or anything to promote needs to read World Wide Rave: Creating Triggers that Get Millions of People to Spread Your Ideas and Share Your Stories.
