About this extension
🚀 SEOSense – Professional SEO Audit & Website Analyzer

Improve your website’s SEO and technical quality with SEOSense, a powerful Chrome extension built directly into the Chrome Side Panel. Analyze the webpage you are viewing, identify important issues and receive clear, actionable recommendations without switching tabs or uploading website data to an external service.

🔍 INSTANT SEO ANALYSIS

Get a clear SEO health score based on important and relevant webpage checks. SEOSense reviews the live page and helps identify missing, incomplete or incorrectly configured SEO elements.

📝 META TAG AUDIT

Analyze the page title, meta description, canonical URL, robots directives, viewport settings, HTML language and indexability signals. SEOSense also highlights title and description length issues that may affect how the page appears in search results.

🏷 HEADING STRUCTURE ANALYSIS

Review the complete H1 to H6 structure of the page. Find missing H1 tags, multiple H1 headings, empty headings, skipped heading levels and content hierarchy problems.

🔗 ADVANCED LINK EXPLORER

Inspect internal and external links, anchor text, nofollow attributes, sponsored links and UGC links. Detect empty anchors, insecure HTTP links and external links that may require safer security attributes.

🖼 IMAGE SEO AUDIT

Find images with missing or empty alt text, missing dimensions, oversized display sizes and limited responsive-image support. SEOSense also identifies opportunities to use modern image formats.

🧩 SCHEMA AND STRUCTURED DATA

Detect JSON-LD structured data used on the current page, identify available schema types and highlight invalid JSON-LD markup that may prevent search engines from understanding the content correctly.

📱 SOCIAL MEDIA PREVIEW

Review Open Graph and Twitter Card metadata, including social titles, descriptions and images. Preview how the page may appear when shared on supported social platforms.

⚡ PERFORMANCE INSIGHTS

Review available page-loading and browser-session information, including Largest Contentful Paint, Cumulative Layout Shift, DOM size, scripts, resources and third-party domains. Performance values may vary depending on the device, connection and current browser session.

♿ ACCESSIBILITY CHECKS

Detect common accessibility issues involving image alternatives, form labels, button names, heading structure, link text, page language and basic semantic markup. Automated checks are helpful for identifying potential problems but do not replace a complete manual accessibility audit.

📖 CONTENT INTELLIGENCE

Review word count, estimated reading time, readability, paragraph structure and content-length indicators. These insights help content writers and SEO professionals evaluate whether a page is clear, useful and properly structured.

💻 DEVELOPER DIAGNOSTICS

Identify duplicate HTML IDs, deprecated elements, inline styles, script-loading patterns, async and defer usage, module scripts, resource hints, responsive-image implementation and third-party resources.

🛠 ACTIONABLE RECOMMENDATIONS

SEOSense does more than identify issues. It provides practical explanations, recommended fixes and copy-ready examples wherever appropriate, helping developers and content teams resolve problems faster.

📊 PROFESSIONAL REPORTS

Export audit results as PDF, CSV or JSON for client reports, development tasks, internal documentation and team collaboration.

🌗 RESPONSIVE LIGHT AND DARK MODE

Use SEOSense comfortably with a clean, responsive interface designed for the Chrome Side Panel. The extension supports both light and dark themes, sleek bordered cards and navigation optimized for narrow and wide panel sizes.

🔒 PRIVACY-FOCUSED

SEOSense analyzes the active webpage locally in your browser. No account is required, browsing data is not sold and no remote code is executed. Analysis begins only when you open and use the extension.

🎯 BUILT FOR PROFESSIONALS

SEOSense is suitable for SEO specialists, web developers, digital marketers, content creators, freelancers, agencies and website owners who need fast and practical webpage insights.

Start using SEOSense to find SEO issues, improve technical implementation, review content quality and create professional website audit reports directly inside Chrome.
