PageChecks: SEO Checker

Run instant on-page SEO checks on the current tab for meta tags, canonicals, robots, headings, images, and Open Graph.

PageChecks: SEO Checker gives you instant, on-page SEO analysis for any website you visit — right from your browser toolbar. No sign-up, no API keys, no waiting. Just click the icon and get actionable results in seconds. 🔍 SIX BUILT-IN SEO CHECKS Run one check at a time or scan all six at once: • Meta Tags — Verify your title tag length, meta description, viewport, language attribute, and robots directives are all set up correctly. • Canonical URL — Confirm the right canonical tag is in place so search engines index the correct version of your page. • Robots Directives — Check whether crawlers can find and index your page, and spot any noindex or restrictive directives before they hurt your rankings. • Headings — Audit your heading hierarchy for missing H1s, duplicate H1s, and skipped heading levels that confuse readers and crawlers. • Image Alt Text — Find images with missing or empty alt attributes that hurt accessibility and image search visibility. • Open Graph — Preview how your page will look when shared on social media, and catch missing OG titles, descriptions, images, or Twitter card tags. ⚡ HOW IT WORKS 1. Navigate to any website. 2. Click the PageChecks icon in your toolbar. 3. Tap a check or hit "Check Everything" to run all six. 4. Review your score, findings, and plain-English recommendations. Every check returns a score out of 100, a breakdown of what passed, what needs attention, and what's failing — plus clear "How to fix it" guidance so you know exactly what to do next. 📌 RESULTS THAT STICK Your results are saved per page, so you can close the popup, keep working, and come back later without re-running anything.
