AI-SEO Page Auditor Chrome Extension
The AI-SEO Page Auditor Chrome extension runs 43 AI-readiness checks on any page you are browsing. Letter grade in the toolbar badge, results cached per URL, no sign-up required.
TL;DR: The AI-SEO Page Auditor is a free Chrome extension that runs 43 AI-readiness checks on the page you are currently browsing. The result appears as a letter grade (A through F) in the toolbar badge. No URL to paste, no tab to switch, no account required. Add it from the Chrome Web Store.
The AI-SEO Checker has been available as a web tool for a while. The workflow is simple: paste a URL, wait a few seconds, read the report. It works, but there is friction. You have to copy the URL from the address bar, open a new tab, paste it into the checker, and wait for the fetch. If you are reviewing twenty pages before a content audit, that friction adds up.
The Chrome extension removes it. Navigate to any page, click the toolbar icon, and the audit runs immediately against the URL you are already on.
What it does
The extension reads your active tab's URL and forwards it to the AutomateLab audit proxy at automatelab.tech/api/audit-fetch. The proxy fetches the page server-side, bypassing client-side rendering quirks, runs the same 43 checks as the web tool, and returns a structured report. The full breakdown appears in a popup. The letter grade appears in the toolbar badge -- visible before you even open the popup.
Results are cached in chrome.storage.local keyed by URL. Revisiting the same page after a fresh audit is instant. This matters when you are scanning a batch of pages: the first visit fetches, every repeat visit loads from cache in under a second.
What it checks
The 43 checks cover six categories that determine how AI assistants discover, parse, and cite content:
Structured data -- JSON-LD presence, correct schema types (Article, BreadcrumbList, FAQPage, SoftwareApplication), valid markup against the expected shape.
Semantic HTML -- Heading hierarchy, presence of article and main elements, readable content structure with adequate text density.
Crawlability -- Robots meta tags, canonical declarations, noindex and nofollow flags that could block AI crawlers.
Page metadata -- Title and description length and uniqueness, Open Graph tags, Twitter card markup, language declaration.
Performance signals -- Total page weight, number of external dependencies, render-blocking resource count.
Citation signals -- Author markup, publication and modification dates, breadcrumb schema, organization identity, HTTPS.
Each check returns pass, warn, or fail. The letter grade is the weighted roll-up. The popup shows every check individually so you can see exactly which ones are dragging the score down and what to fix.
How to install
- Chrome Web Store listing for AI-SEO Page Auditor
- Click "Add to Chrome." No account or API key required.
- Navigate to any page and click the AI-SEO Page Auditor icon in your Chrome toolbar.
The extension requests three permissions: activeTab to read the current tab's URL, storage to cache results locally, and tabs to detect tab navigation. It does not read page content, intercept other requests, or transmit any data beyond the URL to the proxy.
A typical workflow
You are reviewing a set of pages before a content strategy session. Open each page in a tab. Click the extension icon. The letter grade appears in the badge within two to three seconds. Pages graded D or F get flagged for immediate attention -- click the badge to open the popup and check which specific signals are failing.
Repeat visits within the session are instant from cache. You can move through a long list of URLs without waiting for a network fetch each time.
The grades match the web tool exactly. The extension and the checker share the same proxy, the same 43 checks, and the same weighting table. The extension is a faster path to the same report.
