To understand how our standard sampling works before you change any settings, click here.
If you find that sampling 1% of your visitors or registered users is returning too much, you can set the percentage to less than 1%.
In your Wootric Settings, click "Customize In-app Sampling".
Scroll down to "Registered Users % Surveyed" or "Visitor % Surveyed". Change the number in the box on the right to whatever decimal percentage you would like.
