About SEO Deep Crawler

The SEO Deep Crawler is an ultra-fast, client-side website auditing tool. By acting as a mini search engine crawler, it fetches the HTML of any target URL and breaks down its SEO health. It instantly reveals missing meta tags, improper heading structures (like multiple H1s), missing image alt tags, and content length, giving you an immediate SEO score without needing bulky desktop software.

Features

• Instant Crawling: Fetches and parses target URLs in seconds.
• SEO Health Score: Automatically calculates a score based on best practices.
• Heading Extractor: Pulls out all H1, H2, and H3 tags so you can see the content structure.
• Missing Alt Tag Detection: Finds images that are missing crucial alt text for accessibility and SEO.
• No Sign-ups Required: Completely free to use with no limits.

How to Use

1. Enter the full URL (e.g., https://example.com) of the page you want to analyze.
2. Click 'Analyze' and wait a few seconds for the crawler to fetch the data.
3. Review the SEO Health Score and actionable warnings (Red/Yellow icons).
4. Check the 'Extracted H1 Content' section to see the main topics of the page.
5. Use the feedback to improve your own page or audit a competitor's page.

Frequently Asked Questions

How is this different from other SEO tools?

Unlike Ahrefs or Semrush which require paid subscriptions and take time to queue crawls, this tool performs an instant, on-demand client-side crawl using a proxy to bypass CORS restrictions.

Why did a URL fail to crawl?

Some highly secure websites block proxy requests or automated fetching (like Cloudflare protection). If a site blocks the request, our crawler cannot read its HTML.

Does it crawl the entire website?

No, this is a 'Single Page Analyzer'. It deep-crawls the exact URL you provide, not the entire domain. To check another page, simply enter its specific URL.
