If you do a web search for free viral marketing, you will see the system at work. Offering something “free” is part of the strategy. None of these companies actually offer free advertising. They may offer free information. But, it will be just enough to make you curious and want to learn more.
Reports, trials, test-runs and leads are some of the things that they offer. Of course, if you want more, you will have to pay. That’s how this sort of advertising campaign works. It is what you want to do with your business, too.
Whatever you are selling or whatever service you provide, you need to identify something that you can give away. Perhaps you are an expert carpenter. You can offer do it yourself advice and either publish on your website, an online magazine or create a newsletter for people that are interested in carpentry. Then find a way to let people know that you offer this information.
