❓ SEO Audit Tool - What Every Check Means
🔍 HTTP Status
What it checks: Does your page return a proper 200 OK response?
Why it matters: Error codes (404, 403, 500) block Google from indexing + scare visitors away.
✅ PASS: Page loads perfectly. ❌ FAIL: Fix server errors.
🔒 HTTPS Security
What it checks: Does your site use secure HTTPS protocol?
Why it matters: Google ranks HTTPS higher + browsers show "Not Secure" warnings on HTTP.
✅ PASS: Green lock icon. ❌ FAIL: Get SSL certificate (free via Let's Encrypt).
📝 Title Tag
What it checks: Your page <title> length (50-60 chars optimal).
Why it matters: Shows in Google results - too long gets cut off, too short misses keywords.
⚠️ WARNING: Adjust to 50-60 chars with main keyword first.
📄 Meta Description
What it checks: <meta name="description"> length (140-160 chars optimal).
Why it matters: Google snippet under title - drives clicks from search results.
⚠️ WARNING: Add compelling CTA + keywords (140-160 chars).

What it checks: <meta name="viewport"> tag presence.
Why it matters: 60% traffic is mobile - without viewport, site looks broken on phones.
🎯 H1 Tag
