I Built PagePulse — A Free Landing Page Analyzer That Runs in Your Browser
I needed a quick way to audit landing pages without signing up for expensive SEO tools. So I built one.
PagePulse scores any landing page across 5 categories and gives you a letter grade (A-F) with specific, actionable fixes.
What It Checks
| Category | What's Analyzed |
|---|---|
| SEO | Title tag, meta description, heading hierarchy, image alt text, canonical URL |
| Performance | Document size, image count, script count, external requests |
| Accessibility | Alt text coverage, form labels, heading hierarchy, color contrast signals |
| Mobile | Viewport meta, touch-friendly elements, responsive indicators |
| Content | Word count, paragraph structure, CTA presence, readability |
How It Works
- Enter a URL
- PagePulse fetches the HTML and analyzes it client-side
- Get a score (0-100) for each category + overall grade
- See exactly what's wrong and how to fix it
No API keys. No server processing. No data leaves your browser.
Tech Stack
- Vanilla JavaScript — zero dependencies, loads instantly
- GitHub Pages — free hosting
- ~800 lines of code — built in one afternoon
Why I Open-Sourced It
Most landing page tools either:
- Cost $50+/month (Ahrefs, SEMrush)
- Are locked behind signups (Google PageSpeed needs an API key for batch use)
- Give you scores without actionable fixes
PagePulse is free, instant, and tells you exactly what to change.
