Frequently Asked Questions

Which tool is best for tracking guest-to-user conversion?

Amplitude offers the most robust tracking for guest sessions, including session stitching and behavioral funnels that help identify exactly where users drop off before authentication.

Can these tools help reduce EULA or login drop-off?

Yes. All three tools can track EULA acceptance and login attempts, but Amplitude and Heap provide deeper retroactive and path analysis to pinpoint friction points in the flow.

Do any of these support plain-language recommendations like 'buy now or wait'?

Not natively, though Amplitude’s custom insights and anomaly detection can be configured to trigger alerts that mimic decision-support logic for internal teams.
