Yes, it sounds too simple to be an advice. But wait! What do you already know? There are a few tricks to shorten down a questionnaire effectively.
Sometimes you can even include another question without increasing the length.
You can use personalized survey links, providing a connection to known data. This applies whenever you deal with customers you already know.
Every customer might have a unique identifier, most probably a number or alphanumeric code. By including it to a survey link, there is no need to ask demographics anymore.
Some other features can help you to include a data connection within the link. You can use parameters, variables, email invitation and multi-links to shorten down the answering time. Of course you get all of the mentioned options on easyfeedback.
