The Problem with Most SEO Tools

Let's be honest: most SEO tools are either expensive, require lengthy signups, or collect your data. If you're a developer shipping a new feature, a content creator optimizing a blog post, or a small business owner checking your site health, you don't need a $99/month subscription—you need quick, actionable insights.

What if you could run a comprehensive technical SEO audit in seconds, completely free, with no account required?

Real-World Example: Quick Wins

Here's what a typical audit might reveal:

Performance Issues:

  • LCP of 4.2s (should be under 2.5s) → compress hero image
  • 3 render-blocking scripts → defer non-critical JavaScript
  • CLS of 0.15 → add image dimensions

SEO Fundamentals:

  • Title: 68 characters (optimal: 50-60) → shorten by 8-18 chars
  • Missing meta description → add 150-160 character summary
  • No canonical tag → add to prevent duplicate content issues

Structured Data:

  • Article schema detected but missing dateModified
  • No Organization schema → add for brand signals

Fix these in 30 minutes, re-run the audit, and watch your scores improve.

SEO Insights vs. Paid Tools

Don't get me wrong—tools like Ahrefs, SEMrush, and Moz are powerful. But they're overkill if you just need a technical health check.

Technical Details for Developers

SEO Insights leverages modern web APIs and best practices:

  • Fetch API: Retrieves page content and headers
  • Lighthouse: Core Web Vitals scoring (when available)
  • DOM parsing: Extracts meta tags, structured data, and links
  • Robots.txt parser: RFC-compliant validation
  • Sitemap XML parser: Validates structure and URLs

The tool runs primarily client-side, meaning your URLs aren't logged server-side (except for the initial fetch through our proxy to handle CORS).
