PageChecks: SEO Checker

About

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. If the page content changes, stale results are flagged automatically so you know when to re-check.

🚀  GO DEEPER WITH PAGECHECKS.COM

The extension connects to PageChecks.com, which offers 30 free SEO tools — including a full site-wide audit, SERP simulator, content intelligence suite, and more. No account required.

✅  PRIVACY-FIRST

PageChecks: SEO Checker runs entirely in your browser. Page analysis happens locally — your data is never sent to any server. The only network requests are the ones you initiate when you choose to open a tool on PageChecks.com.

Permissions used:
• activeTab — to read the current page's HTML for analysis
• scripting — to run the analysis script on the page
• storage — to save your results and theme preference locally
