- Make sure that you are presenting valuable (additional) information that makes it worth the scan.
Check your codes (on multiple devices when possible).
Make sure the site is mobile -friendly. (Certain videos will not play on a mobile, some "games" are too difficult to play on mobile, loaded webpages are difficult to navigate.
- Add the URL below the code (#1 for kids/parents without a device & #2 helps in case of a bad code)
We did not have good luck with colored (fun) codes (stuck with black).
Use a shorter URL whenever possible (easier to read).
Don't link to sites that need a login that your audience may not have.
Watch codes for youtube videos because of the comments and other suggested videos (we use Viewpure).
