  • Rage Clicks vs Dead Clicks: What’s the Difference and Which UX Problems Matter Most?

    Rage Clicks vs Dead Clicks: What’s the Difference and Which UX Problems Matter Most?

    Dead clicks are unresponsive clicks with no visible feedback. Rage clicks are rapid repeat clicks that usually signal frustration.

    Introducing Lift AI: Stop Guessing What to Fix Next

    Every product team has the same dirty secret: they collect more behavioral data than they can act on. Session replays pile up unwatched. Heatmaps confirm what everyone already suspected. Funnels show where users drop off, but not why, and definitely not what to do about it. The real bottleneck was never data collection. It’s prioritization.…
