Promoting your cause doesn't need to take a lot of money. It can also take place through less costly methods, such as good old-fashioned word of mouth. Convincing people through a one-on-one conversation can be just as effective at changing someone's point of view as the best made commercial, or even more so. (Think about it. Which would make you get a tetanus booster: a television commercial or a suggestion from your doctor?) Word of mouth is a highly desirable part of social marketing.
The plan should cover one year. For small companies, this is often the best way to think about marketing. Things change, people leave, markets evolve, customers come and go. Later on we suggest creating a section of your plan that addresses the medium-term future--two to four years down the road. But the bulk of your plan should focus on the coming year.
Affiliate marketing is commonly confused with referral marketing, as both forms of marketing use third parties to drive sales to the retailer. The two forms of marketing are differentiated, however, in how they drive sales, where affiliate marketing relies purely on financial motivations, while referral marketing relies more on trust and personal relationships.
