SEORadar

All-in-one SEO analysis tool. Scan meta tags, headings, images, links, schema & more in 1 click.

SEORadar You just published a blog post. Looks great. But is it actually optimized? You check the title — seems fine. You scroll through the page looking for your H1. You right-click, inspect the meta description, only to discover it's 200 characters long. You open a separate tab to test your Open Graph tags. You paste the URL into a structured data validator. Thirty minutes later, you still don't have a clear picture of your page's SEO health. This is the reality for content creators, SEO specialists, and web developers who care about search performance. The tools are scattered, slow, and most of the popular ones still run on code written before Chrome even supported Manifest V3. WHY SEO AUDITING IS STILL A MESS The problem isn't that SEO is complicated. The problem is that the information you need is buried in the DOM, spread across multiple tools, and never shown to you in one place. - Title tag length? Open DevTools and count manually. - Heading hierarchy issues? Scroll through the entire page source. - Missing alt text on images? Inspect each image element one by one. - Open Graph preview? Use a separate social card validator. - Page load timing? Open Lighthouse and run a full audit. - robots.txt content? Navigate to the file manually. Most people either skip these checks entirely or spend 20 minutes switching between tabs and tools to piece together a basic audit. SEORadar puts all of it in one panel, one click, zero waiting. WHAT THIS EXTENSION DOES SEORadar is a lightweight SEO analysis toolbar built from scratch on Chrome Manifest V3. It runs entirely in your browser — no external APIs, no accounts, no data sent anywhere. Click the icon on any webpage, and you get a complete SEO audit in under a second. No spreadsheets. No manual DOM inspection. No separate tools for each check. Here's what you get: SEO Health Score — A weighted score from 0 to 100 based on 20 checks across meta tags, headings, images, links, structured data, and performance. One number that tells you where the page stands. Title and Description Audit — See your title tag and meta description with character counts, color-coded by length. Green for optimal (30-60 chars for title, 120-160 for description), yellow for borderline, red for missing. Full Meta Tag Inspector — Canonical URL, robots directives, viewport, charset, language, keywords, and hreflang tags — all displayed with pass/warn/fail indicators. Plus a scrollable list of every meta tag on the page. Heading Hierarchy Analysis — Every heading on the page in DOM order, with indentation showing the hierarchy visually. Heading level skips are flagged with a SKIP badge — a feature you will not find in competing tools. If your page jumps from H1 straight to H3, you will know immediately. Image Alt Text Audit with Fix Suggestions — See which images have alt text and which don't. For images missing alt attributes, SEORadar analyzes the filename and generates a suggested alt text as a starting point. This is a unique feature — instead of just flagging the problem, it gives you something to work with. Link Breakdown — Total count of internal links, external links, anchor links, and nofollow links. Each link is listed with its URL, anchor text, and attributes. External and internal links are grouped separately for easy scanning. Social and Structured Data Preview — Live Open Graph preview showing how your page will appear when shared on social platforms. Twitter Card tag display. JSON-LD structured data rendered in a readable format. If any of these are missing, you get specific guidance on what to add. Technical Performance Panel — Time to First Byte (TTFB), DOM Ready, DOM Interactive, and Page Load timings. DOM node count and depth. HTML page size and total transfer size. Counts of external scripts, inline scripts, stylesheets, and inline styles. Plus robots.txt content display and sitemap.xml detection — all in one panel that competing tools simply do not offer. HOW IT WORKS 1. Install SEORadar from the Chrome Web Store. 2. Navigate to any webpage you want to analyze. 3. Click the SEORadar icon in your toolbar. 4. Review your SEO score and drill into each tab for details. That's it. Full audit in one click, results in under a second. WHY A SIDE PANEL INSTEAD OF A TINY POPUP Most SEO extensions cram everything into a small browser popup. The result is cramped text, horizontal scrolling, and missing details. SEORadar uses a properly sized popup window with seven organized tabs — Summary, Meta, Headings, Images, Links, Social, and Technical. Each tab focuses on one area so you can analyze without visual clutter. Switch between tabs to explore different aspects of the page, and everything stays in context. EXPORT OPTIONS CSV Export — Download your full SEO checklist as a CSV file with check name, pass/fail status, and weight. Import it into Google Sheets, share it with your team, or track progress over time. Clipboard Copy — One click to copy a formatted text summary of your entire SEO audit, including score, title, description, link counts, heading counts, and all check results. Paste it into Slack, email, or a project ticket. PDF Export — Print your audit as a PDF using the built-in browser print dialog. All seven tabs are expanded so nothing is hidden. Archive your audits or share them with clients. DARK MODE Toggle between light and dark themes with one click. Your preference is saved locally and persists across sessions. No account needed. No sync. Just a comfortable reading experience whether you're working at noon or midnight. REAL SCENARIOS WHERE THIS HELPS Pre-Publish Content Check: You are about to hit publish on a new landing page. You click SEORadar and immediately see your title is 72 characters — too long for most search results. Your meta description is missing entirely. You catch both issues before the page goes live. Two minutes of checking prevents weeks of poor search visibility. Client SEO Audit: A client asks why their product page isn't ranking. You open the page, click SEORadar, and instantly see they have three H1 tags, heading hierarchy jumps from H2 to H4, and 14 out of 20 images are missing alt text. You export the CSV and send them a clear action list. Developer QA Before Deployment: Your team just pushed a staging build. You click SEORadar and check the Technical tab — DOM node count is 4,200, TTFB is 800ms, and there are 47 external scripts loaded. You flag these performance issues before they reach production. Open Graph Debugging: A marketing team member reports that shared links on LinkedIn show the wrong image. You open the Social tab and immediately see the og:image tag is pointing to a 404 URL. Found in 10 seconds instead of 10 minutes of inspecting elements. Heading Structure Validation: You maintain a content-heavy blog. After a CMS migration, you suspect heading structures may have broken. You check each key page with SEORadar — the SKIP badges in the heading tree instantly reveal which posts have hierarchy issues that need fixing. Competitive Research: You want to understand how a top-ranking competitor structures their page. You visit their URL, click SEORadar, and see their exact heading hierarchy, keyword density, internal link structure, and structured data implementation — all without leaving the page.
