Toollium SEO Audit

Audit one page or your whole sitemap: on-page, technical, schema, speed & AI search readiness. Free, runs in your browser.

Audit any page in one click, and get a plain-English fix for everything it finds. Toollium SEO Audit scores a page across five areas: on-page SEO, technical setup, structured data, loading performance including Core Web Vitals, and how visible the page is to AI answer engines. Every warning explains what to change, not just what is wrong. AI SEARCH READINESS Most SEO tools still only think about Google. This one also checks whether the AI crawlers behind today's answer engines are allowed to read your page. Each crawler is shown separately, so you can see exactly which ones are blocked in your robots.txt rather than getting a single blended score that hides the detail. It checks whether you have an llms.txt file, and will draft one for you from your page's own heading structure if you don't. It also looks at the signals answer engines rely on when deciding what to quote: machine-readable dates, author and expertise signals, question-style headings, readability, and whether your structured data is shaped for answer extraction. There is also a one-click button that opens your question in ChatGPT or Perplexity, so you can check for yourself whether your page gets cited. This opens a normal browser tab. No AI service is ever called by the extension. WHAT ELSE IT CHECKS On-page work covers your title and description, with a pixel-accurate preview showing where each one truncates in search results, plus heading structure, image alt text, canonical tags and your link profile. Technical checks cover security headers, compression, mobile viewport and language settings, indexability, and whether a sitemap can be found. Structured data is checked for whether it parses, which types are present, and whether each type carries the fields Google actually requires for rich results. Performance reporting includes Largest Contentful Paint with the responsible element highlighted on the page itself, layout shift, main-thread blocking time and total page weight. Cached pages are reported honestly rather than given a flattering number that means nothing. PREVIEW HOW YOUR PAGE LOOKS ELSEWHERE See how the page renders as a Google result, and how it appears when shared on X or LinkedIn. The social preview follows what each platform actually does, which is not the same thing, so you find out before you post rather than after. SCAN YOUR WHOLE SITEMAP Site Scan checks ten, twenty or fifty pages from your sitemap and groups what it finds by issue, with the affected URLs listed. Instead of being told a page has no H1, you get the six pages that are missing one. It reads raw HTML, so anything rendered by JavaScript is invisible to it. The tool says so plainly rather than reporting a false problem. INSPECT AND REPORT Separate tabs list every heading, link, image and schema block on the page, with skipped heading levels and missing alt text flagged inline. Any list can be copied straight into a spreadsheet. The printable report carries the score, a summary of what passed and failed, and a fix for every finding, sorted worst first. It is meant to be sent to a client or a developer as it is. You can also copy the whole audit as Markdown for a ticket. PRIVACY Everything runs in your browser. There is no account, no analytics, no tracking and no server of ours involved. The only requests the extension makes are for the audited site's own robots.txt, llms.txt and sitemap, which are public files anyone can open. Nothing you audit is collected, stored or sent anywhere. Free, with no locked features. Built by Toollium.
