Why a survey QR raises response rates
For lecture evaluations, event feedback, or store satisfaction surveys, 'please type this URL' collects almost nothing — nobody hand-types a long address.
Put a large QR on your final slide or an exit banner, and participants scan and answer right from their seats. Responses collected on the spot always outnumber ones requested later.
Preparing the form link
Google Forms: click 'Send' → the link icon and copy the address. Enable 'Shorten URL' to get a forms.gle/... link — a shorter link makes a simpler, easier-to-scan QR.
Naver Form (Office): copy the link from the form's Share menu. Both are ordinary URLs, so a URL-type QR works as is.
Creating and displaying the QR
In 'Create QR', paste the link as the URL type and download. Use a large PNG on presentation slides (at least a third of the screen height) and SVG for printed banners.
Keep the slide up for at least 10 seconds with a prompt like 'Scan now — 30-second survey'. In a dark room, a bright slide background scans better.
Tips for more responses
Telling people how long it takes ('done in 1 minute') lowers the barrier. Keep it to 10 questions or fewer.
At events, a small reward — a coffee coupon raffle among respondents — works remarkably well. Note the reward right next to the QR.
