A good rule of thumb is to aim for at least 100 replies that you can work with.

You can use our sample size calculator to get a more precise answer, but understand that collecting feedback is research, not experimentation. Unlike experimentation (such as A/B testing), all is not lost if you can’t get a statistically significant sample size. In fact, as little as ten replies can give you actionable information about what your users want.

There’s no perfect answer to this question, but we recommend asking as few as you need to ask in order to get the information you want. Remember, you’re essentially asking someone to work for free, so be respectful of their time.

A big pile of qualitative data can seem intimidating, but there are some shortcuts that make it much easier to analyze. We put together a guide for analyzing open-ended questions in 5 simple steps, which should answer all your questions.

Honestly, the real danger is not collecting feedback. Without knowing what users think about your page and why they do what they do, you’ll never create a user experience that maximizes conversions. The truth is, you’re probably already doing something that bugs them more than any survey or feedback button would.

If you’re worried that adding an on-page survey might hurt your conversion rate, start small and survey just 10% of your visitors. You can stop surveying once you have enough replies.
