When it comes to offline promotion and marketing, then there is no other effective tool such as the word of mouth. Let us take the scenario that a person purchases a book from your online store and was pleased with the service, he will then refer your services to ten other people. In the event that these other people are also like your services then they will further go ahead to recommend the service to ten other people and the snow ball effect continues. This will generate a significant amount of traffic to your website. There are a number of tools and devices that can stimulate word of mouth interaction such as t-shirts, digital postcards, photos, certificates, and awards. Moreover, the online presence of your brand can work further to stimulate word of mouth simply by being effective and engaging. The result of this will be an almost self-sufficient traffic generating method. However, it is important to note that your traffic will only be as good as how your online brand is engaging.
