Audit any web page in 20 seconds

Paste a web address. We load it on a desktop and a phone and run over 60 checks on speed, accessibility, structure, SEO, AI search and meta tags. Every problem is pinned on a screenshot, with how to fix it.

What the audit checks

We load your page twice in a real browser: once at desktop size, and once as a phone with a slower processor, the way most people actually visit. Then we run over 60 checks in six areas. The SEO and AI search checks are the same ones SEOgent uses, so the two always agree.

Speed
How long the main content takes on a phone (LCP), layout shift, blocking JavaScript, server response, page weight, render-blocking files, oversized and old-format images, lazy loading and web fonts.
Accessibility
The axe-core rules used by most accessibility checkers: colour contrast, alt text, form labels, button and link names, landmarks, ARIA and more, pinned on the element.
Structure
Broken links (a sample), files that fail to load, JavaScript errors, insecure content, redirects, robots.txt, the XML sitemap, noindex, and whether the page fits on a phone with tappable buttons and readable text.
SEO
Title and meta description length, one H1, heading order, canonical, language, image alt text, internal links, content depth, HTTPS, URL shape and HTML basics.
AI search
Whether AI crawlers can read the page without JavaScript, structured data, question headings and FAQ schema, an answer up front, lists and tables, how recent it is, and facts with sources.
Meta tags
Mobile viewport, Open Graph and X (Twitter) cards, whether the share image actually loads and is big enough, favicon and home screen icon, plus previews in Google and when shared.

From the list to the fix

Every problem comes with what to do about it, and the ones that live on a particular element are pinned on the screenshot so you can see exactly where. When you’re ready to fix them, Copy as a prompt gives you the whole list as instructions for Claude Code, Cursor or any AI coding agent. Download report saves it as a Markdown file to share with your team or client.

FAQ

Is it really free?

Yes. No account, no email. There’s a limit on how many pages one person can audit an hour, to keep it fast for everyone.

Why don’t the speed numbers match PageSpeed Insights?

Every speed test depends on where it runs and what device it pretends to be. We measure from our server with a phone-sized screen and a processor slowed down four times, which is close to a mid-range phone. PageSpeed Insights uses its own lab setup and, when it has it, data from real Chrome users. Treat both as guides and look at the trend: if a fix makes our number better, it’ll make theirs better too.

Does it check my whole site?

No, it audits only the exact page you give it. It also looks at your robots.txt and sitemap, to make sure search engines can find the page. To audit your whole site on a schedule, use SEOgent.

Can automated checks find every accessibility problem?

No. Automated rules catch roughly a third of accessibility issues: the ones a machine can measure, like contrast and missing labels. Use the audit to clear those, then test with a keyboard and a screen reader for the rest.

Why couldn’t it load my page?

The page might be behind a login, blocking automated browsers, or taking too long to load. We can only check public websites on the normal web ports.

Do you store the results?

We keep each audit, with its screenshots, so you can share the link. Results aren’t listed anywhere public, and screenshots are deleted after 30 days. If you’d like one removed sooner, get in touch.
