One great way to get your customers spreading WOM is to integrate your customers into the message itself.
Take for example this personalized video produced by WOMMA member Vanksen USA for Lifelock, an identity theft protector product. (http://www.culture-buzz.com/blog/The-Apprentice-LifeLock-Puts-You-On-Screen-2136.html). The video allows a person to enter in their own name or their friends name, and integrate them into the story-line of the video. You have probably seen similar videos, such as the ballot-themed personalized videos that circulated leading up to Election Day.
That being said, we’re not necessarily advocating shelling out dollars for personalized videos, though if you can afford it many of the videos are pretty darn entertaining and go viral.
But, perhaps personalized stickers with customers’ names? Or member pins, or customer faces integrated into flash videos? Something to grab your customers attention by utilizing your customers themselves.
