AI-SEO Page Auditor Chrome Extension -- 43 checks, letter grade in the toolbar

The AI-SEO Checker has been available as a web tool for a while. The Chrome extension removes the copy-paste friction.

What it does

Install, navigate to any page, click the icon. The extension reads your active tab's URL, runs 43 AI-readiness checks, and shows the report in a popup. The letter grade (A-F) appears in the toolbar badge.

Results are cached in chrome.storage.local keyed by URL. Repeat visits are instant.

What it checks

• Structured data -- JSON-LD presence, correct schema types, valid markup
• Semantic HTML -- heading hierarchy, article/main elements
• Crawlability -- robots meta, canonical tags, noindex flags
• Page metadata -- title/description length, Open Graph, Twitter cards
• Performance signals -- page weight, external dependencies
• Citation signals -- author markup, dates, breadcrumb schema, HTTPS

Each check returns pass/warn/fail. The popup shows the full breakdown.

Install

1. Chrome Web Store listing
2. Click 'Add to Chrome' -- no account required
3. Click the extension icon on any page

Permissions: activeTab (read current URL), storage (cache results), tabs (detect navigation).
