Where Users Give Up
Your analytics show the drop-off. CBrowser shows you why.
Six cognitive layers. One abandonment score. The exact bottleneck killing your conversion rate.
Google Analytics Tells You WHAT Page Users Leave
CBrowser tells you WHY. It simulates real cognitive behavior across six measurable layers, turning vague bounce rates into specific, fixable bottlenecks.
Your copy scores at a 12th-grade reading level. Half your audience reads at 8th grade. They leave before they understand your value prop.
Your pricing page presents 47 decision points. Users with moderate patience abandon after 12. The rest never click "Buy."
Your form has 14 fields with 32x28px touch targets. On mobile, 23% of taps miss. Users retry twice, then leave.
How It Works
Point CBrowser at any URL
One tool call. No SDK, no tag manager, no pixel. Pass a URL and an optional persona.
It measures 6 cognitive layers per persona
Saliency, cognitive load, decision complexity, motor accessibility, frustration, and readability. Each scored independently.
You get abandonment risk + exact bottleneck
A single percentage that tells you the probability of user drop-off, plus the specific layer causing it.
The 6 CTC Layers
Cognitive Transport Cost (CTC) decomposes user experience into six independent, measurable layers. When one layer spikes, you know exactly what to fix.
When it's the bottleneck: Users cannot find the CTA. Their eyes land on decorative elements instead of the action.
When it's the bottleneck: Too much information competing for attention. Users feel overwhelmed and default to "back."
When it's the bottleneck: Paradox of choice. Users cannot decide between options, so they decide to leave.
When it's the bottleneck: Touch targets too small, spacing too tight. Users with any motor limitation miss clicks.
When it's the bottleneck: Micro-friction compounds. Each small annoyance drains patience until the user quits.
When it's the bottleneck: Reading level exceeds user capability. They skim, misunderstand, and lose trust.
Example Output
A single tool call returns the full 6-layer breakdown with an overall abandonment risk percentage and the specific bottleneck layer.
