Saves SEO professionals time by providing instant access to page-level technical SEO data (meta tags, headings, links, images, structured data, Core Web Vitals, HTTP status codes, social previews) without needing to view page source or use multiple separate tools

User browses any webpage → clicks the extension icon → popup opens showing 8 tabs of SEO data extracted from the current page DOM → user reviews overview metrics, inspects headings/links/images/schema, previews social cards, checks HTTP status chain → user exports data as CSV/TXT for further analysis

Target users: SEO professionals / Digital marketers / Web developers / Content creators auditing on-page SEO

The techseo.pro course linked in the footer may be a paid external product, but this is not integrated into the extension itself

No paid features detected

The extension is explicitly described as a 'free extension' in the Chrome Web Store description. All paid/pro keyword hits were false positives: 'subscription' (MediaSubscription: schema.org type in js/types.js:613), 'checkout' (CheckOutAction: schema.org type in js/types.js:169), 'purchase' (OfferForPurchase: schema.org type in js/types.js:795), 'upgrade' (HTTP status code 426 'Upgrade Required' label in js/popup.js:456), 'pro' (part of extension name 'SEO Pro' in file paths and URLs), 'license' (MIT license references in third-party libraries). No payment processing, subscription management, feature gating, premium tier UI, Stripe/payment SDK integration, or upgrade prompts exist in the codebase. All features (Overview, Headings, Status, Links, Images, Schema, Social, export functions) are fully accessible without any paywall.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension operates entirely locally by scraping SEO data from the current page DOM. All 'auth' and 'account' keyword hits were false positives: HTTP status code labels (401 Unauthorized, 407 Proxy Authentication Required, 511 Network Authentication Required) in js/popup.js lines 421-470, and schema.org type definitions (AuthenticContent, BankAccount, etc.) in js/types.js. No login forms, OAuth flows, token management, or authentication checks exist anywhere in the codebase. The only external API call (Google CrUX API at background.js:29-45) uses a hardcoded API key with no user authentication.
