Description
Next.js SSR / DOM Audit is a powerful technical SEO tool that compares server-rendered HTML against client-rendered DOM to identify hydration mismatches, missing SEO elements, and hidden content issues.
π What It Does
Phase 1 - SSR Analysis
-Captures the initial server-rendered HTML and analyzes critical
SEO elements before JavaScript hydration.
Phase 2 - DOM Comparison
After hydration, compares DOM state to find elements that were:
-Added by JavaScript (potentially invisible to search engines)
-Modified after initial render
-Hidden in accordions, tabs, or FAQ sections
β¨ Key Features
-Health Score Dashboard
-Get an instant 0-100 health score with color-coded severity breakdown (Critical, Warning, Info issues).
-Smart Element Detection
Navigation & buttons added by JS
-Images loaded client-side
-Links with SEO impact (dofollow/nofollow analysis)
-JSON-LD structured data (SSR vs DOM-only)
-Form elements and interactive components
Hidden Content Detection β NEW
-Finds accordion, tab, and FAQ content that exists in DOM but is CSS-hidden. This content may not be reliably indexed by search engines.
Visual Page Overlays
-Toggle visual highlights directly on the page to see exactly where issues occur. Click any item to jump to it and isolate it visually.
Isolation Mode
-Click any detected element to isolate it with a highlighted outline while dimming others - perfect for client presentations or detailed inspection.
Link Equity Analysis
-Tracks internal vs external links, dofollow vs nofollow distribution, and identifies DOM-only links that may not pass link equity.
Export Reports
-Export findings as JSON or CSV for documentation, client reports, or further analysis.
π₯ Who It's For
-SEO Engineers auditing JavaScript-heavy sites
-Developers debugging SSR/hydration issues
-Technical SEOs validating Next.js, Nuxt, Gatsby implementations
Agencies creating client deliverables
