Social QR codes work best when they point to a public profile or channel that will not change after you print it.
Use stable links
- Use the canonical profile URL, not a temporary share link.
- Avoid links that require a login to view.

- Add a short label like “Scan to follow on Instagram”.
- Keep high contrast and test on mobile.
