Watch What Google Sees
How It Works
Three steps to uncover what search engines actually see
1. Fetch Raw HTML
We request your page and capture the initial HTML response — exactly what a crawler sees first.
2. Render with JavaScript
We run your JavaScript in a real browser environment and wait for the DOM to settle.
3. Compare & Report
We diff the raw and rendered versions, flagging critical SEO elements that changed or disappeared.
What We Detect
Comprehensive checks for JavaScript rendering issues
Title & Meta Tags
Verify title, description, canonical, and robots meta are present in raw HTML
Missing Content
Detect headings, links, and text that only appear after JavaScript runs
Structured Data
Check if JSON-LD schema is in raw HTML or added client-side
JavaScript Errors
Surface runtime errors that might prevent rendering
Redirect Chains
Track HTTP redirects and identify unnecessary hops
Internal Links
Compare link counts before and after rendering
