Word of Mouth Marketing

Moonfruit offered 11 Macbook Pros and 10 iPod Touches to celebrate its 10th anniversary. To qualify, contestants had to send a tweet using the hashtag #moonfruit. One month following the completion of the contest, Moonfruit site traffic was up 300 percent and sales increased by 20 percent — all with a meager investment of $15,000. The company also realized SEO benefits, by landing on the first results page of Google for “free website builder.”
