Unlock Global Reach with Flawless Hreflang Implementation!
Struggling with the complexities of international SEO? Hreflang Genius is your all-in-one Chrome extension built for SEO professionals, web developers, and digital marketers who need to validate, analyze, and troubleshoot multilingual website implementations with confidence. Say goodbye to guesswork — get actionable answers in seconds.

Why Hreflang Genius?
Incorrect hreflang implementations cause search engines to misread your site's language and regional targeting, silently harming your international visibility. Hreflang Genius gives you a complete diagnostic suite inside a clean, modern minimalist interface built around a professional green theme — fast to read, easy to act on.

Core Features
🚀 Real-Time Hreflang Detection
Instantly detects hreflang tags from both the <head> HTML and HTTP Link response headers as you browse — covering every delivery method Google supports. The parser handles any attribute ordering in Link headers, so no valid tag is ever missed.

✅ Intelligent Validation System
Syntax & Formatting: Checks every hreflang value for correct structure.
ISO Code Verification: Validates language codes against ISO 639-1 and verifies language-region combinations (e.g. en-GB, zh-TW).
Duplicate Detection: Flags duplicate language-region codes that confuse search engines.
Self-Reference Check: Confirms the current page includes a return tag pointing to itself.
🔗 Automated Reciprocal Link Checking
Asynchronously fetches every alternate URL and verifies it correctly links back to the current page — a hard requirement for a valid hreflang set. Results update live in the table as checks complete.

↪️ Redirect Detection on Hreflang URLs
Detects when any hreflang target URL responds with a redirect (301/302). Google ignores hreflang tags that point to redirected URLs — these are flagged with a clear inline badge so you can fix them before they damage your international rankings.

🌍 Language / Region Coverage Map
A visual grid of all declared hreflang combinations, grouped by base language and color-coded by health status — green for healthy, amber for warnings or redirects, red for syntax errors, and purple for x-default. Hover any tile for a full status breakdown.

⭐ x-default Tag Validation
Automatically flags when an hreflang set is missing an x-default fallback tag, which Google recommends for handling users whose language or region isn't explicitly targeted.

🏷️ HTML Lang Attribute Check
Verifies that the page's <html lang=""> attribute matches one of the declared hreflang values. Mismatches and missing attributes are surfaced as actionable warnings.

🗂️ XML Sitemap Consistency Check
Dynamic Discovery: Reads your robots.txt to find all declared Sitemap: URLs — no hardcoded paths. Falls back to common paths only when robots.txt has no directives.
Sitemap Index Traversal: Automatically drills into sitemap indexes to search child sitemaps, supporting the multi-sitemap architecture used by large international sites.
Hreflang Consistency Diff: Compares the xhtml:link entries inside your sitemap's <url> block against the page's declared hreflang tags, highlighting any mismatches in either direction.
🔎 Raw vs. Rendered HTML Comparison
Detects discrepancies between hreflang tags in the raw server response and the client-side rendered DOM — essential for JavaScript-rendered and SPA websites where tags may be injected or modified after load.

⚠️ Canonical & Hreflang Conflict Detection
Identifies conflicts between your rel="canonical" declaration and your hreflang annotations before they send mixed signals to search engines.

Dashboard & UI
📊 At-a-Glance Summary Panel
Four live dashboard tiles — Hreflang Tags, Issues Found, Languages, and HTML Lang — give you an instant health snapshot the moment analysis completes.

📋 Detailed Data Table
A sortable table displaying every detected tag with its language code, URL, source (DOM or HTTP Header), syntax validity, return tag status, redirect badge, and any per-tag issues. Zebra-striped rows and pill-shaped status badges keep large tag sets readable.

🎨 Modern Minimalist Interface
A clean, flat design built on a professional Emerald green palette with ample whitespace, subtle shadows, and smooth section transitions — designed to be fast to scan and easy on the eyes during long audit sessions.

💡 Actionable Fix Suggestions
Every detected issue includes a plain-English explanation and a concrete fix suggestion — no need to cross-reference documentation to understand what went wrong.

📤 Export to JSON & CSV
Export the full hreflang tag dataset for offline reporting, sharing with clients, or feeding into your own audit pipelines.

Built for international SEO professionals who need more than a tag counter — Hreflang Genius gives you complete visibility into every layer of your multilingual implementation.
