Whether you're a one-man shop or a large enterprise with hundreds of customer service representatives, each interaction with a customer is an opportunity to get great content.
Build.com, ranked #68 on Internet Retailer's Top 100 list in 2016, built a content generation program that included customer service rep interactions, and motivated their reps to participate.
The rep responsible for the most project photos submitted won $250. Posters promoting the internal incentive were printed and pinned up around the Build.com office, including in the restrooms.
Customer Service Rep Program Poster
Build.com inserted a light-weight call-to-action into the reps' email signatures. Similar to this:
The reps were also encouraged to close a conversation with an "ask" for the customer to submit their before-and-after project photos. You can do this, too. Create a vanity URL that redirects to your Rivet Collector URL.
For example: mystore.com/stories
A vanity URL like the one above will be short enough for your customer service reps to communicate over the phone and simple enough for your customers to remember.
If you don't have the budget to offer an employee a monetary reward like Build.com did, consider other non-monetary perks. For example, for a week the winner gets to ask other team members to fetch them coffee from the break room anytime they want a cup!
