Traffic percentage for an experiment is the percentage of your website visitors you want to participate in the experiment. Depending on the percentage assigned, Nelio A/B Testing randomly includes your website visitors in the experiment. This feature is helpful if you want to run the experiment on a small number of visitors.

For example, if your website receives 100 visitors a day and you want to run the experiment through just 20 visitors, specify the percentage as 20%.

To assign the traffic percentage, move the slider from left to right in the Advanced tab of the Settings menu (only for customers that hold a Professional Plan subscription).
