On-Page SEO Audit 🩺

Get a clear, objective on-page SEO report for any web page — score + prioritized fixes.

Give it one or more URLs (or let it crawl a whole site). For each page it checks the on-page SEO factors that matter and returns a 0–100 score plus a plain-English list of issues to fix.

What it checks

• 🏷️ Title tag — presence + length (30–60 chars)
• 📝 Meta description — presence + length (70–160 chars)
• 🔠 Headings — H1 presence/uniqueness + full H1–H6 counts
• 🖼️ Images — how many are missing alt text
• 🔗 Canonical tag — present or missing
• 🚫 Indexability — flags noindex pages (won't show in Google)
• 📱 Mobile — viewport meta tag
• 🔒 HTTPS
• 📣 Open Graph / Twitter tags (social previews)
• 🧩 Structured data — JSON-LD schema types found
• 🌐 hreflang + internal/external link counts
• ⏱️ Response time

Why it's accurate

Every check is a deterministic parse of exactly what the page returns — no estimates, no guessing. The score is a transparent weighting of these objective checks (issues list shows precisely what lowered it).

Input

{
"startUrls":["https://example.com"],
"maxPages":1,
"useProxy":false
}

Example output (1 page)

{
"url":"https://example.com",
