Audits now start from a library of ready-made checks: important events, all events, consent implementation, acceptance rate, tag manager changes, cookie banner accuracy, new events or properties, Web Vitals, the data layer, and the match between destinations and the data layer.

**Update, September 22:** the ** UTM naming convention** check joins the library. ** Update, September 30:** the cookie banner check compares the cookies the banner declares with the ones the browser actually receives, before and after accepting; when it cannot conclude, it says why.

**Who it is for:** anyone who would rather pick a check than describe one; you can still adjust it in the chat that configures the audit.

**Where:** Audits, New audit. How audits run: [Audits: every check is a conversation](/changelog/audits-every-check-is-a-conversation).
