# Experiments

A/B Testing is the most essential tool marketers can use to target visitors by testing their responses to varying content. An Experiment holds two or more variants — each a file and a Frequency (traffic-split percentage) — and tracks Views and Conversions per variant so you can see which one actually performs best. Click an Experiment's name to view or manage it.
