This is a relatively easy way to drive some viral marketing and get your customers (and employees) involved. Print some unique t-shirts that prominently feature your logo or brand. Give them to all employees, and ship them to customers.
Then tell them to get out there and start taking pictures. Feature the best photos on your Web site, your blog, your social channels. Create contests for the most creative use of the t-shirt, the farthest away from your headquarters, the most unique location. Incorporate them into scavenger hunts (especially at your user conferences).
Make one day every week “YOUR BRAND HERE t-shirt day”. Encourage employees and customers to wear their t-shirts that day and send pictures.
Growing up in a suburb of San Francisco, a local Wilderness Supply shop did something very similar. They featured these distinctive green bags they would use to send you home with whatever you bought. And their back wall was covered in photos of their customers proudly holding up their green Wilderness Supply bags all over the world – on mountaintops, in remote areas, at the North and South poles, at the bottom of the ocean and more.
It’s fun, it’ll get people involved, it’ll spark new ideas and creativity, and I can measurably drive referrals and new business as well.
