Core Web Vitals and accessibility, measured like Google measures them
Slow pages lose rankings and revenue; inaccessible pages lose users and invite legal risk. Our site health check runs Google's PageSpeed analysis for your Core Web Vitals and audits your pages against WCAG 2.2 accessibility rules, all in one report.

Core Web Vitals
The performance metrics Google uses as ranking signals, measured through the official PageSpeed analysis.
Largest Contentful Paint (LCP)
Loading performance. Your main content should render within 2.5 seconds. Rated good, needs improvement, or poor.
Interaction to Next Paint (INP)
Responsiveness. Under 200ms means the page reacts instantly to every tap and click.
Cumulative Layout Shift (CLS)
Visual stability. A score above 0.1 means your content jumps around while loading.
First Contentful Paint (FCP)
How quickly anything renders. Under 1.8 seconds keeps users from bouncing.
Accessibility (WCAG 2.2)
Automated checks against the standard behind accessibility law in most markets, with each failure explained in plain language.
Color contrast
Detects text that low-vision users, and anyone in sunlight, can't read.
Image alt text
Finds images with no text alternative for screen readers.
Button & link names
Catches icon-only controls that screen readers announce as just "button".
Form labels
Verifies every input has an associated label announcing its purpose.
Heading order
Flags skipped heading levels that break navigation for assistive technology.
Document language & title
Checks the lang attribute and page title screen readers announce first.
ARIA correctness
Validates ARIA roles and attributes. Wrong ARIA is worse than none.
Viewport zoom
Detects viewport settings that block low-vision users from zooming.
