AI product read

Analyze and verify all links on a web page, identifying broken, unverified, nofollow, follow, internal, and external links

Helps SEO professionals and web developers quickly identify broken links, categorize link types (follow/nofollow, internal/external), and audit page link quality without manually checking each link

1. User navigates to any web page and clicks the extension icon. 2. Content script (cs-page.js) scans all <a> tags on the page. 3. For each link, the extension sends a request (via background service worker) to check HTTP status codes, classifying links as good/broken/unverified. 4. Simultaneously, unique URLs are batched and sent to the LRT Power*Trust API to retrieve trust/power metrics. 5. The popup widget (widget.html) displays real-time progress with counts for working, broken, and unverified links, each split by follow/nofollow and internal/external. 6. Users can click completed counts to open a detailed link table (links.html) with filtering and CSV/XLSX export. 7. Hovering over any link on the page shows a popover with link details and source HTML.

Target users: SEO professionals / Web developers / Content managers / Digital marketers / Link building specialists

The LRT API (plugin.linkresearchtools.com) uses credentials:'include' in fetch calls (LRT.js:100), which could theoretically send browser cookies to the LRT server, but this is for the public API with a hardcoded key, not user auth
The extension's parent company (LinkResearchTools) offers paid SEO tools, but no extension features are gated behind those paid plans

Monetization

No paid features detected

The extension itself is completely free with no gated features. All link-checking, export (CSV/XLSX), Power*Trust metrics, nofollow highlighting, and filtering work without any payment. The extension name explicitly states 'Free'. There are no subscription, billing, premium, or upgrade mechanisms in the source code. The 'Try LinkResearchTools' button (widget.html:171) is a promotional CTA for the parent LRT product suite, but no extension features are locked behind it.

Confidence: 90
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension has no login UI, no account creation flow, and no authentication mechanism. It uses a hardcoded API key (js/lrt/LRT.js:10) for the LRT Power*Trust API, so no user authentication is needed. All core link-checking functionality works immediately after installation without any login.
