QR code or link: putting your survey where people are
askingIndia

People answer best close to the moment you are asking about. So the question is not only what to ask, but where the survey meets them.
A QR code for places
On the counter, on the packaging, on a receipt, at the exit of an event. Anywhere people stand with a phone in their hand and a minute to spare.
A link for messages
In a WhatsApp message, an email or an SMS after a delivery, an appointment or a support call. Any channel you already use to reach your customers can carry the link.
Say what to expect
Next to the code or the link, say three things: that they will answer on camera, roughly how long it takes, and that they can speak in their own language. People are more willing to start something when they know what it involves.
