What are the best practices for getting real results from bumper stickers?

Bumper stickers get read at a glance from a moving car, so clarity beats cleverness every time.

• Keep the message to seven words or fewer
• Use high-contrast colors so it reads from a distance
• Include one clear next step, like a short URL or QR code
• Leave breathing room so nothing crowds the trimmed edges

A scannable QR code linked to your landing page gives curious drivers an easy way to act while the message is still fresh in mind.
