Audit any website in under a minute
Performance, SEO, accessibility, and AI-agent readiness - scored, explained, and fixed with AI suggestions tailored to your stack.
What the audit measures
Five scores, each 0-100, from a single scan.
Performance
Largest Contentful Paint, Cumulative Layout Shift, Time to First Byte, and Total Blocking Time, measured on desktop and a 375px mobile viewport.
SEO
Title tags, meta description, canonical tags, Open Graph, structured data, and robots directives.
Accessibility
Color contrast, missing alt text, ARIA attributes, and form labeling, mapped to WCAG 2.1/2.2 success criteria.
Best practices
Console errors, deprecated APIs, image aspect ratios, and other general web-health signals.
A fifth score most audits skip: Agent Readiness
AI assistants increasingly browse the web on a person's behalf. The Agent Readiness score checks whether your page gives them what they need to do that correctly - stable layout, accessible interactive elements, and machine-readable structure. It's computed the same way every other category is: a real in-browser audit plus a handful of targeted checks, not a marketing number.
Buttons, links, images, form labels, and ARIA attributes need accessible names for an AI agent to act on them, not just a human eye.
An agent targeting a button that just moved will click the wrong thing. Full credit under 0.1 CLS.
A machine-readable summary of your site at /llms.txt, the same convention Scanverra's own site uses.
Schema.org markup that tells an agent what your content actually is.
Marks where your primary content starts.
Marks your navigation for structured site traversal.
A robots.txt that blanket-blocks GPTBot, ClaudeBot, CCBot, and similar agents loses these points.
How it works
Three steps from URL to actionable report.
Paste your URL
Enter any public URL - no install, no agent, no browser extension required.

A full audit runs in under a minute: performance profiling, SEO checks, accessibility validation, and the agent-readiness pass.

Frequently asked questions
Five categories: Performance (Core Web Vitals), SEO (metadata and crawlability), Accessibility (WCAG-mapped issues), Best Practices (general web-health signals), and Agent Readiness (how well an AI agent or assistant can navigate and understand your page). Each is scored 0-100.
Yes. Performance is measured on both a desktop profile and a 375px mobile viewport, since the two often score very differently - a site can be fast on desktop and slow on mobile, or the reverse.
As more traffic comes from AI assistants browsing on a user's behalf, a page's structure matters as much as its content. Agent Readiness scores things like layout stability, accessible names on interactive elements, and machine-readable markup (llms.txt, JSON-LD) that make a page easier for an agent to act on correctly.
Yes. Scanverra detects your framework or CMS first, then writes fix suggestions for that specific stack - a Next.js site gets next/image and metadata-API guidance, a WordPress site gets plugin and caching guidance, and so on.
Yes, from your scan history or directly from a report page. Re-scanning is unlimited and free for the Website Audit tool.
