What happens over time
- Day one
Clear failures, like a server error or an outage, are caught once a visitor tries again.
- After 20 real completions
It knows what normal looks like for your action, so it can catch subtler failures.
- Always
It fails open. If SiteAirbag can't load, your site carries on as if it weren't there.
Designed for the standard ways a browser completes a journey: forms, links, buttons, in-page steps, dialogs and embedded widgets.
