Website Auditor Tool - SmartappS

SmartappS – Website Auditor & SEO Health Checker SmartappS is a free Chrome extension built for developers, QA engineers, digital marketers, and content teams who need fast, reliable audits of any web page — without leaving the browser. Open the popup on any tab and get an instant, structured report covering every layer of your page: on-page SEO signals, heading structure, metadata quality, image optimization, link health, accessibility, JavaScript analytics, and more. WHAT SMARTAPPS AUDITS 🔍 On-Page SEO Instantly inspect the page title, meta description, canonical tag, robots meta, Open Graph tags, and Twitter Card metadata. SmartappS shows you exactly what search engines see — character counts, missing fields, duplicate tags, and quick-fix guidance included. 🏷️ Heading Structure Visualize H1–H6 hierarchy at a glance. Detect missing H1 tags, skipped heading levels, and empty headings that hurt both SEO and screen-reader accessibility. 🖼️ Image & Alt Text Audit List every image on the page with its alt text status. Find images with empty, missing, or overly generic alt attributes so you can fix accessibility and image-search visibility in one pass. 🔗 Link Auditor (Internal & External) Scan all anchor tags — internal links, external links, and downloadable file links. SmartappS checks for broken links, redirect chains, empty href values, target="_blank" without rel="noopener", and non-descriptive anchor text (e.g. "click here", "read more"). ♿ Accessibility Checks Run a built-in accessibility audit covering ARIA roles, form labels, keyboard-focusable elements, color-contrast warnings, and landmark regions. Every finding is mapped to WCAG 2.1 criteria so your team knows exactly what to fix and why. 📊 Analytics & Data Layer Inspector Inspect the active data layer (Google Tag Manager / GA4 / custom implementations) event-by-event. Write custom test cases to validate that specific events fire with the correct properties — ideal for QA before a GTM release. ⚡ Performance Signals Fetch live Google PageSpeed Insights scores for both mobile and desktop. View Core Web Vitals (LCP, FID/INP, CLS) and Lighthouse category scores without switching tabs. 🤖 AI-Powered Audit Summaries (Gemini) Get a plain-English summary of every issue found on the page, prioritized by impact. Perfect for sharing findings with stakeholders who need context, not raw data. QA TEST CASES & RULES ENGINE SmartappS ships with a configurable rules engine. Define your own test cases for: Anchor link validation — set expected URL patterns and mark rules as pass/fail. Data Layer events — write property-level assertions on any GTM/GA4 event. Meta tag rules — enforce title length ranges, required OG properties, canonical policy. Run all rules with one click and get a color-coded pass/fail report. Results stay in the popup for easy copy-paste into your bug tracker. ON-PAGE VISUAL HIGHLIGHTS Toggle SmartappS overlays directly on the live page: Highlight anchor tags — see every link outlined with pass/fail color coding based on your anchor rules. Highlight heading levels — see H1–H6 outlined and labeled on the rendered page. Highlight images without alt text — spot missing alt attributes without opening DevTools. Overlays update in real time as you navigate and are cleared automatically when you close the popup. SPACE MANAGEMENT SmartappS includes a built-in storage manager that shows you exactly how much browser local storage the extension is using, which keys are stored, their sizes, and whether they are system defaults or user-created data. You can delete non-system keys individually with one click — keeping your browser storage clean. SETTINGS & CONFIGURATION Every audit module is fully configurable from the Settings panel: Set your Google PageSpeed API key for unlimited performance checks. Customize which tab opens by default. Define anchor link test cases with expected URL patterns. Write and save data layer event assertions. Export and import your full configuration as a JSON backup. WHO IS SMARTAPPS FOR?
