Readability & Cognitive Load
Your content is too complex. Your analytics prove it. CBrowser measures exactly where and why.
Seven readability metrics. Eight cognitive load dimensions. Per-page scoring that turns vague bounce rates into specific content problems you can fix today.
7 Readability Metrics Per Page
Every page on your site gets scored across seven independent readability dimensions. No aggregate “readability score” that hides which factor is the problem.
How much content is packed into the viewport. High density overwhelms users who need time to process.
Layout complexity and element density. Measures how many competing visual elements fight for attention.
Longer words require more decoding effort. Normalized across script families for cross-language comparison.
Longer sentences demand more working memory. Each additional clause increases the chance of losing the reader.
Type-token ratio measuring vocabulary variety. High diversity signals sophisticated writing that excludes casual readers.
Fraction of words with 7 or more characters. A proxy for reading difficulty that correlates with comprehension failure.
Fraction of words with 10 or more characters. Flags jargon-heavy copy that alienates non-expert audiences.
Script-Family Aware
Most readability tools assume English. CBrowser calibrates for three script families, so your international content gets accurate scoring instead of meaningless numbers.
Standard word boundaries and character counting
1.8 characters per word equivalent. No spaces between words.
1.6x normalization factor. Root-based morphology changes word length calculus.
8 Cognitive Load Dimensions
Readability is one layer of cognitive load. CBrowser measures all eight dimensions and identifies the bottleneck that actually drives users away.
Total content the user must absorb to take action
Layout complexity and visual noise competing for attention
Number of elements demanding focused awareness
Choices presented that require active evaluation
Physical interaction effort for clicks, scrolls, and taps
Reading difficulty based on vocabulary and sentence structure
Information the user must hold while navigating
Time and effort tolerance before the user abandons
Page-by-Page Comparison
The analytics dashboard compares readability across every page on your site. Radar charts show per-page cognitive profiles. Bar rankings identify your worst offenders. Scatter plots reveal the relationship between complexity and bounce rate.
Overlay cognitive profiles for any two pages. See exactly which dimensions differ.
Sort all pages by any single metric. Find the highest technical density or longest sentences instantly.
Plot readability score against real engagement metrics. Prove the correlation to stakeholders.
