Show a different product every month with a caption or brief description. Include a QR code and website link that will bring prospects directly to more information about the product or even a demo. Highlighting other company attributes each month—such as an exceptional guarantee, terrific service, fast delivery or response, extraordinary selection, customization, and so on--can be effective as well.
Run a monthly or annual contest requiring participants to scan a QR code or enter a URL leading them to a landing page asking for a piece of information about the product or service shown that month so you know they’re learning about them and you capture information for follow-up marketing.
Consider devoting a page to your website with the link. After all, your prospects are right at their computers, mouse in hand, and your website is just a few keystrokes and a click away.
