Cognitive Transport Cost

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. Vague bounce rates become specific, fixable bottlenecks.

Readability Bottleneck

Your copy reads at a 12th-grade level. Half your audience reads at 8th grade. They leave before they understand your offer.

Decision Overload

Your pricing page has 47 decision points. Users with average patience quit after 12. The rest never click "Buy."

Motor Friction

Your form has 14 fields with 32x28px tap 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 tracking 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 on its own.

You get abandonment risk + exact bottleneck

One percentage showing how likely users are to drop off. Plus the exact layer causing it.

The 6 CTC Layers

Cognitive Transport Cost (CTC) breaks user experience into six independent, measurable layers. When one layer spikes, you know exactly what to fix.

Saliency

How well the page guides visual attention to key elements.

When it's the bottleneck: Users cannot find the CTA. Their eyes land on decoration instead of the action.

Cognitive Load

The total mental effort needed to process the page.

When it's the bottleneck: Too much information fights for attention. Users feel overwhelmed and hit "back."

Decision Complexity

How many choices the user faces and how hard each one is.

When it's the bottleneck: Too many options. Users cannot pick one, so they leave instead.

Motor Accessibility

The physical effort needed to interact with page elements.

When it's the bottleneck: Tap targets too small, spacing too tight. Users with any motor limitation miss clicks.

Frustration

Built-up negative signals from errors, slow loads, and blocked paths.

When it's the bottleneck: Small annoyances add up. Each one drains patience until the user quits.

Readability

How easily the target audience can read and understand the text.

When it's the bottleneck: Reading level is too high for the user. They skim, misunderstand, and lose trust.

Example Output

One tool call returns the full 6-layer breakdown. You get an abandonment risk percentage and the specific bottleneck layer.
