SEO Inspector - On-Page Technical Diagnostics EN

SEO Inspector is a lightweight browser extension for SEO specialists, web developers, content creators, and marketers who need quick, actionable technical SEO diagnostics.

Inspect the active page directly in Microsoft Edge, including its rendered content, metadata, structured data, links, and browser performance timings.

9 Comprehensive Diagnostic Tabs

1. Overview: Inspect page titles, meta descriptions, canonical URLs, robots directives, HTTP status information, and OpenGraph/Twitter social metadata.

2. Content: Analyze H1–H6 heading hierarchy, word count, estimated reading time, and keyword density.

3. Links: Review internal and external links, nofollow, sponsored and UGC attributes, insecure links, and anchor text. Export link information to CSV.

4. Hreflangs: Inspect language-targeting annotations, x-default declarations, and potential hreflang configuration issues.

5. Images: Find missing alt text, broken images, missing dimensions, and image formats including WebP, AVIF, SVG, PNG, and JPG.

6. Structured Data: Inspect JSON-LD structured data, identify Schema.org types, detect JSON syntax errors, and access external validation tools.

7. PageSpeed & Performance: Review browser Navigation Timing metrics, including Time to First Byte (TTFB), DNS lookup, TCP/TLS connection timing, DOM readiness, and page load time. Inspect resource counts and available transfer-size information. Open Google PageSpeed Insights for a separate external performance audit.

8. GSC & GA4 Tracking: Detect Google Analytics, Google Tag Manager, Google Search Console verification tags, Meta Pixel, and other common tracking integrations.

9. Consolidated Issues: Review critical issues, warnings, and passed checks. Export technical audit findings as Markdown or JSON reports.

Privacy & Data Handling

SEO Inspector performs page inspection and performance calculations directly in your browser. It does not operate a developer-controlled analytics or telemetry backend.

Extension preferences, such as audit thresholds, report settings, and branding preferences, use browser storage. Some preferences may synchronize between devices when browser account synchronization is enabled.

The Google PageSpeed API integration is not active in this version. External performance audits open separately in Google PageSpeed Insights.

SEO Inspector provides convenient technical diagnostics without requiring a developer-operated cloud auditing service.
