# Configuring Experiment Analytics

> Configures the analytics side of a PostHog experiment — exposure criteria (default $featureflagcalled vs custom exposure events), primary and secondary metrics, the supported metric types (count, sum, ratio with math and mathproperty, retention with retentionwindowstart and starthandling), multivariate user handling ("Exclude" vs "First seen variant"), and how to read results once the experiment is live. Use when the user adds or edits a primary or secondary metric (e.g. "add a secondary metric tracking 'downloadedfile' per user"), sets up a ratio metric (e.g. "revenue from purchasecompleted / pageviews"), sets up a retention metric (e.g. "$pageview → uploadedfile, 7-day window"), configures custom exposure (e.g. "only count users who hit /checkout"), changes multivariate handling, or asks "who is in the analysis?", "how do I measure impact?", "is this winning?", "what's the confidence level?", or "should I ship?".
