Why Website Health Matters
Your website is often the first interaction a potential customer has with your brand. A slow, insecure, or poorly optimized site drives visitors away before they ever see your product. Website health scanning gives you a clear picture of where your site stands — and what to fix first.
PageVital scans any publicly accessible URL and delivers an actionable health report in seconds, covering four critical categories: performance, security, SEO, and technology stack.
Running Your First Scan
Getting started takes less than a minute:
- Navigate to the PageVital homepage
- Enter any public URL in the scan input field
- Click Scan Now and wait for the analysis to complete
- Review your overall grade and category breakdowns
No signup is required for your first scan. You'll see results immediately, including an overall letter grade (A through F) and individual scores for each category.
Understanding Your Results
Each scan evaluates your site across 33+ automated checks grouped into four categories:
- Performance — Core Web Vitals (LCP, CLS, FID), server response time, and resource optimization. Weighted at 30% of your overall score.
- Security — HTTPS configuration, security headers (CSP, HSTS, X-Frame-Options), and mixed content detection. Weighted at 25%.
- SEO — Meta tags, heading structure, canonical URLs, Open Graph tags, and crawlability signals. Weighted at 25%.
- Technology — CMS detection, JavaScript frameworks, server software, and CDN usage. Weighted at 20%.
Each check returns a status of pass, warn, or fail along with a brief explanation of what was found and why it matters.
Reading the Score Breakdown
Grades follow a straightforward scale:
| Grade | Score Range | Meaning | |-------|-------------|---------| | A | 90–100 | Excellent — your site follows best practices across the board | | B | 80–89 | Good — minor improvements recommended | | C | 70–79 | Fair — several areas need attention | | D | 60–69 | Poor — significant issues detected | | F | 0–59 | Critical — urgent fixes required |
Most websites land in the C to B range on their first scan. Reaching an A requires consistent attention to all four categories.
Fixing Common Issues
Here are the most impactful fixes for each category:
Performance
Optimize your largest contentful paint (LCP) by compressing images and using modern formats like WebP or AVIF. Enable text compression (gzip or Brotli) on your server.
# Enable gzip compression in nginx
gzip on;
gzip_types text/plain text/css application/json application/javascript text/xml;
gzip_min_length 256;
Security
Add security headers to your server configuration. At minimum, configure Strict-Transport-Security, X-Content-Type-Options, and X-Frame-Options.
SEO
Ensure every page has a unique <title> tag and meta description. Add Open Graph tags for social sharing previews. Verify your site has a valid robots.txt and XML sitemap.
Technology
Keep your CMS, frameworks, and server software up to date. Outdated versions often have known vulnerabilities that show up in both security and technology scores.
Tracking Progress Over Time
Create a free PageVital account to save your scan history and track improvements over time. Each scan is stored in your dashboard with the full report, making it easy to compare before-and-after scores as you make changes.
Pro users get unlimited scan history, PDF report exports, and priority access to new features.
Next Steps
Run your first scan now and see where your site stands. Focus on the highest-impact fixes first — typically performance and security — and rescan after making changes to measure your progress.
