88% of users won't return after a bad experience

Is your website actually easy to use?

Aperion's Usability AI agent evaluates every page for navigation clarity, cognitive load, mobile interaction patterns, and UX best practices - then gives you a prioritised list of improvements that reduce friction and keep users engaged.

The cost of poor usability

Bad UX drives users away silently

High abandonment

88% of users won't return after a bad experience

First impressions are permanent. Confusing navigation, unclear information architecture, or overwhelming interfaces send visitors to competitors - and they rarely come back.

Mobile friction

60% of web traffic is mobile - but mobile UX lags

Most websites are designed desktop-first. Mobile users encounter smaller tap targets, hard-to-read text, confusing gestures, and layouts that break on smaller screens.

Cognitive overload

Too many choices reduce conversions by 30%

The paradox of choice is real. Too many navigation options, competing CTAs, and cluttered pages overwhelm visitors into inaction. Simplicity is a conversion strategy.

Support cost

Poor usability drives 22% of support tickets

When users can't find what they need or complete tasks independently, they contact support. Usability issues have a direct cost in support time and brand friction.

Setup

Usability Analysis Coverage

Every interaction. Every page.

Aperion's Usability AI agent evaluates pages across four key dimensions - navigation structure, cognitive demand, mobile experience, and interaction quality. Each dimension maps to real user behaviour and measurable conversion outcomes.

Navigation analysis

Navigation depth and labelling are the two most common causes of user confusion. This page has a 4-level deep navigation structure and 6 unlabelled links.

  • Navigation too deep (4 levels vs. max 3)
  • Missing breadcrumbs on deep pages
  • No site search present
  • 6 link labels are ambiguous
  • 3 broken internal links 
{
  "nav_depth": "4 levels (too deep)",

  "breadcrumbs": false,
  "search": "missing",
  "broken_links": 3
}

Cognitive load assessment

High content density, 5 competing CTAs, and a Grade 15 reading level are overwhelming users before they can act.

Mobile usability

11 touch targets are below the 44×44px minimum. Horizontal scrolling is present. This page will frustrate mobile users significantly.

Frequently asked questions

Aperion's Usability AI agent checks navigation clarity, information architecture, cognitive load, mobile usability, interaction patterns, and error prevention. It evaluates pages against established usability heuristics including Nielsen's 10 principles, covering everything from menu depth and tap target sizes to content density and form complexity.
Accessibility focuses on whether people with disabilities can use your website at all - screen readers, keyboard navigation, contrast ratios. Usability focuses on how easy and efficient your website is for all users - clarity, cognitive load, navigation logic, and interaction patterns. Both matter, but they address different failure modes.
Cognitive load refers to the mental effort required to use your website. High cognitive load - caused by cluttered layouts, competing CTAs, inconsistent navigation, or dense text - forces users to think too hard. Research shows that reducing cognitive load directly improves completion rates, time-on-task, and conversion rates.
Mobile users account for over 60% of web traffic, but mobile conversion rates are typically 3x lower than desktop. The primary cause is poor mobile UX - tap targets that are too small, text that requires zooming, layouts that don't adapt, and gestures that don't work as expected. Fixing mobile usability issues is one of the highest-ROI improvements available.
Yes. Aperion's Usability AI agent analyses full-page screenshots and HTML to evaluate UX patterns, navigation structure, content hierarchy, and mobile layout. It applies established usability heuristics to identify friction points that would require expensive user testing to find manually. While user testing remains the gold standard, AI analysis provides fast, scalable usability feedback at a fraction of the cost.
Usability regressions are introduced whenever navigation is changed, new content is added, or layouts are updated. Aperion supports scheduled monitoring so you are notified when a change degrades the usability of a page. This is especially important for e-commerce sites and SaaS products where checkout and onboarding flows are frequently modified.
