Stop switching between dozens of tools. Hurra SEO Plugin brings enterprise-grade on-page SEO analysis, real-user performance data, backlink intelligence, and AI-powered optimization directly into your browser – as a sleek sidebar, right on every page you visit.

Whether you're an SEO manager, consultant, developer, or content strategist, this extension gives you the full picture in seconds.

🔍 ON-PAGE SEO ANALYSIS – DEEPER THAN ANY OTHER EXTENSION
Most SEO tools only see what's in the raw HTML. Hurra SEO Plugin goes further: it analyzes both the pre-render (raw HTML) and the post-render (JavaScript-executed DOM) side by side. This means you instantly see what Google's crawler sees versus what users see – an essential difference in today's JavaScript-heavy web.

For every page you open, you get a complete audit of:

Title Tag – character count, pixel-width estimate for SERP display, pre/post comparison, detection of duplicate or missing titles
Meta Description – length check with configurable thresholds, pre/post comparison
Canonical Tag – detects the <link rel="canonical"> in HTML and the HTTP Link: header, compares both, flags conflicts and mismatches
Meta Robots & X-Robots-Tag – reads both the HTML meta tag and the HTTP response header, flags noindex/nofollow signals
Heading Structure (H1–H6) – full heading hierarchy, detects skipped levels (e.g. H1 → H3 jumps), pre/post comparison for JS-rendered pages
Hreflang – reads all <link rel="alternate" hreflang="…"> tags and HTTP Link headers, checks for missing x-default, invalid BCP-47 language codes, duplicates, and broken target URLs (via HEAD requests)
Structured Data (JSON-LD, Microdata, RDFa) – full extraction and display, JSON-LD parsing errors, Google Rich Result type detection, required field checks per schema type, pre/post comparison
Open Graph & Twitter/X Cards – all meta properties extracted, length hints, HTTPS vs. HTTP image URL checks, og:url vs. canonical comparison
Language & Charset – html lang attribute, xml:lang, charset from meta tag and Content-Type header

🔗 LINKS & REDIRECTS
Internal & external links with anchor text, image link detection, and rel attributes (nofollow, sponsored, ugc, …)
HTTP status check for each link destination (via staggered HEAD requests) – find broken links instantly
Redirect chain analysis – tracks every HTTP redirect and client-side redirect during the main-frame navigation, visualizes Start → Steps → Final URL, warns on chains longer than two hops

🤖 CRAWL SIGNALS
robots.txt – fetched and parsed live; immediately flags if the current page URL is disallowed for Googlebot
Sitemap detection – discovers sitemap URLs from robots.txt, checks reachability of /sitemap.xml, HEAD-checks all found sitemaps

🖼 IMAGES
All images sorted by transferred byte size (largest first) – find unoptimized images at a glance
Alt text status for each image
File size from Resource Timing API where available
