At a glance
Error Click Rate % is a frustration-signal metric tracked from FullStory data. An error click is a click that coincides with a console or JavaScript error firing in the page. Unlike a dead click or a rage click, this one carries hard technical evidence: the visitor interacted with something and the code threw. This card reports the share of sessions containing at least one error click. It is the closest FullStory gets to handing engineering a reproducible bug, with the exact replay attached.
| What it counts | The percentage of FullStory sessions in the period in which a click coincided with a logged console or JavaScript error. |
| Sample type | Backend API data from FullStory, refreshed on the standard data refresh. |
| Why it matters | Error clicks are direct evidence of a broken interaction, not just a confusing one. Each affected session is a reproducible defect with the replay attached, which is gold for the engineering backlog. |
| Reading the value | Compare the current period to the prior period. A sudden rise usually maps to a recent deploy; pull the affected replays and check the release timeline. |
| Currency | percent |
| Time window | 30D vsP |

Calculation
Calculated automatically from your FullStory data. FullStory flags an error-click event when a click is followed by a captured console or script error; Vortex IQ divides the count of sessions with at least one such event by total captured sessions for the period. See the At a glance summary above for what the metric tracks and the worked example below for a typical reading.Worked example
A representative reading of Error Click Rate % for a typical merchant on FullStory. Imagine the error click rate jumps from 1.2% to 4.5% overnight, breaching the 3% guardrail. The spike lines up with a Tuesday theme deploy. Opening three affected replays shows the same console error firing on the “Add to cart” button for variant products. Engineering rolls back the change and the rate returns to baseline within a day. Without this card the defect would have surfaced only as a slow bleed in add-to-cart conversion. For deeper investigation, use Vortex Mind to correlate the spike with the deploy; for natural-language exploration, ask Ask Viq which pages threw the most errors.Sibling cards merchants should reference together
| Card | Why merchants reach for it |
|---|---|
fs_rage_click_rate | Frustration sibling: repeated clicks on an unresponsive element. |
fs_dead_click_rate | Frustration sibling: clicks on elements that do nothing. |
fs_frustration_score | The composite frustration number that error clicks feed into. |
fs_high_frustration_sessions | The prioritised replay queue where error-click sessions surface. |
fs_worst_frustration_pages | Ranks pages by frustration so you know where to look first. |
Reconciling against the vendor’s own dashboard
Where to look in FullStory’s own dashboard: FullStory surfaces error clicks under its frustration-signals reporting and exposes the underlying console errors on each session replay. Confirm period boundaries and segment filters match the Vortex IQ profile to reconcile cleanly. Why the Vortex IQ value may legitimately differ:| Reason | Direction | What to do |
|---|---|---|
| Period boundary. Vortex IQ uses 30-day rolling by default; FullStory dashboards may use calendar periods. | Variable | Match the period range. |
| Time zone. FullStory uses the account time zone; Vortex IQ aligns to the merchant reporting time zone. | Marginal | Confirm time zone match. |
| Segment scope. A FullStory segment may exclude bot or internal traffic the Vortex IQ profile includes. | Variable | Match segment and filter settings. |
