At a glance
Excessive Scrolling Rate % is the share of sessions where the visitor scrolled frantically, a signal Microsoft Clarity flags when someone scrolls far more than the page warrants. It usually means the visitor could not find what they came for. A rising rate points to layout, content hierarchy, or search problems that are quietly costing you conversions.
| What it counts | The percentage of Clarity-captured sessions exhibiting excessive scrolling behaviour. |
| Sample type | Behavioural session data from Microsoft Clarity (heatmaps and session recordings), refreshed on the standard data refresh. |
| Why it matters | Frantic scrolling means visitors cannot locate what they want, which erodes engagement and sales. |
| Reading the value | Lower is better; an upward trend versus the prior period flags a findability problem worth investigating. |

Calculation
Microsoft Clarity detects when a session involves an unusual amount of scrolling relative to the page, flags those sessions, then expresses them as a share of captured sessions over the window. Vortex IQ reads that rate and compares it to the prior period. See At a glance for the time window and the worked example below for a typical reading.Worked example
A representative reading of Excessive Scrolling Rate % for a typical merchant on Microsoft Clarity. A store saw excessive scrolling rise from 7% to 13% of sessions across 30 days, breaching the 10% alert. The merchant opened the affected heatmaps and found a redesigned category page had pushed key products below a wall of banners. They used Vortex Mind to trace the spike back to the template change date, then asked Ask Viq in plain English which landing pages drove the worst scrolling so they could prioritise the fix.Sibling cards merchants should reference together
| Card | Why merchants reach for it |
|---|---|
clr_avg_scroll_depth | Shows how far visitors actually reach down the page. |
clr_worst_scroll_depth_pages | Pinpoints the pages where scrolling problems concentrate. |
clr_rage_click_pct | Pairs frantic scrolling with frantic clicking for a fuller frustration read. |
clr_dead_click_rate | Reveals whether visitors are also clicking elements that do nothing. |
clr_health_score | Frames this signal against overall UX health. |
Reconciling against Microsoft Clarity
Where to look in Microsoft Clarity’s own dashboard: Open the Clarity Dashboard insights for the excessive scrolling signal, or filter recordings and heatmaps to sessions flagged for it. Confirm the period and filter settings match the Vortex IQ profile. Why the Vortex IQ value may legitimately differ:| Reason | Direction | What to do |
|---|---|---|
| Period boundary. Vortex IQ uses rolling windows by default; Clarity may use calendar periods. | Variable | Match the period range. |
| Sampling. Clarity may sample sessions on high-traffic sites; Vortex IQ reads what Clarity exposes. | Variable | Allow for sampling on busy stores. |
| Filter scope. Profile-level filters (device, channel, bot exclusion) may narrow the Vortex IQ view. | Variable | Match filter settings. |
