Speed & UX
Speed & UX
A fast website is good. A fast website that people enjoy using is even better. ChatSniff finds what slows you down — and what stops visitors from taking action.

What we measure
Lab data from Google Lighthouse on a mid-range phone, plus our own measurements.
Load speed
Lighthouse performance score, server response time, page weight.
Core Web Vitals
LCP, CLS and blocking time, with field data when Google has it.
Mobile experience
Viewport, tap targets, readable text.
Accessibility
Contrast, labels, button names, alt text.
Heavy images & scripts
Images over 500 KB, render-blocking scripts, missing lazy loading.
Lost Customer Detector
Hidden contact, long forms, nothing to click.
Lost Customer Detector
Technical metrics don't speak to business owners. ChatSniff also tells you, in plain words, where a visitor gives up: no visible way to contact you, a form with too many fields, buttons too small to tap, a page that jumps while loading.
