Is your site healthy — and can AI find it?
Accessibility, speed, broken links, AI-readiness and security in one scan, one 0–100 score.
Five checks. One score.
The problems that cost you visitors, rankings and AI visibility — measured together.
Accessibility
Can everyone use your site? Find the barriers that turn visitors away — and the compliance gaps that carry legal risk.
Speed
How long do people wait? Slow pages lose sales and rankings — see exactly which pages drag.
Broken links
Dead ends frustrate visitors and quietly hurt SEO. We crawl every page and flag every 404.
AI-Readiness ✦
Can ChatGPT, Perplexity & Google AI Overviews read you? We check AI-crawler access, structured data and whether your content needs JavaScript to appear.
Security
Check transport security, defensive headers, public exposure signals and high-confidence WordPress vulnerability intelligence — with unavailable checks shown explicitly.
Full Site Check
Start with a fast teaser scan. If OmniCheck finds enough pages to audit, enter your email and the full scan continues here.
One report you can actually send to a client
Plain-language priorities on top, per-page technical detail underneath. No more stitching together Lighthouse screenshots.
FAQ
Short answers for teams evaluating AI-readiness, accessibility, speed, link health, scan limits and data handling.
What does OmniCheck scan?
Every scan runs five checks together: accessibility (axe-core against WCAG 2.2 AA), speed (Lighthouse), broken links (a full-site crawl), AI-readiness (crawler access, structured data and JS-rendering checks) and passive security checks (TLS, defensive headers, exposure signals and available vulnerability intelligence) — combined into one 0–100 score.
What is AI-readiness and why does it matter?
AI-readiness measures whether tools like ChatGPT, Perplexity and Google AI Overviews can access and understand your content — robots.txt rules, schema.org markup, an llms.txt file and whether your content needs JavaScript to render. Sites that fail these checks are invisible to AI answers.
Does the accessibility scan replace a manual WCAG audit?
No. Automated axe-core rules catch a large share of common WCAG 2.2 AA issues, but a full audit also needs manual testing (keyboard navigation, screen readers, cognitive load) that automated tools can't fully cover.
How is the PageSpeed score measured?
We run Google Lighthouse against your pages and report Core Web Vitals — LCP, CLS and INP — alongside an overall speed score per page.
Can OmniCheck scan JavaScript-heavy websites and SPAs?
Yes. Pages are rendered in a real browser before scanning, so client-rendered content is checked the same way a visitor — or an AI crawler — would see it.
How many pages are included in a scan?
The instant teaser checks three pages. Submit your email to continue the full scan across up to 50 pages; registered users have the same 50-page limit. Only administrator-operated scans may be unlimited.
What do I get in the report?
A plain-language "top 3 things to fix" summary, every issue mapped to the exact page it appears on, and a per-dimension score breakdown — exportable as PDF or CSV, or shared via a link.
What data does OmniCheck store?
We store the scan results tied to the URL you submit so you can revisit or share the report. We don't sell your data, and monitored sites are only ever re-scanned on the schedule you set.
