Overview
SEO JavaScript Checker – Smart Audits for JavaScript SEO
SEO JS Checker is a Chrome extension that helps you identify critical JavaScript-related SEO issues. It fetches the page’s raw HTML and compares it to the live, client‑rendered DOM, highlighting differences across head tags, visible text, and links. Use it to quickly spot SEO risks introduced by client‑side rendering.
What it does:
- Head-tag comparisons: title, meta description, robots, canonical, preload, preconnect, hreflang, JSON‑LD, Open Graph, Twitter Card.
- Visible text block diffs for major blocks/headings.
- Link grouping: internal vs. external, with Added/Removed/Changed/Unchanged status.
- Badge indicators: count of changed head items, HTTP status for non‑200, or an unsupported marker.
- Popup tabs: Head, Changes, Links, Text – with filters and CSV export.
Built for SEOs, developers, and site owners who care about how their content appears to Google—before and after JavaScript runs.
