⚡ The Pain vs. Instant Relief

Broken links destroy conversions, damage buyer trust, and leak hard-won search rankings:

• The Catastrophic Cost of Broken URLs: Silent 404s on high-intent landing pages, broken checkout image assets, or 500 server errors on key CTA links cost digital marketing agencies thousands in lost client revenue and wasted ad spend.
• The 1-Click Solution: Run lightweight, recursive HTTP crawler audits with SSRF security protection. Discovers dead links, missing image assets, circular redirect loops, and cross-origin leaks in seconds without clunky desktop software.

Enterprise Crawlers (Ahrefs, Semrush)	$199 – $499 / month	Monthly subscription lock-in	Restricted crawl credits, heavy dashboards
Desktop Crawlers (Screaming Frog)	$259 / year per license	Local CPU & RAM intensive	Cannot trigger programmatically via webhooks

🛡️ Fair-Execution Guarantee

Automated SSRF & Reachability Diagnostics: If the target URL is unreachable, resolves to private/blocked IP ranges (anti-SSRF protection), or encounters DNS resolution failure, the Actor safely terminates and outputs structured diagnostic records. You never waste compute on unresolvable target domains.

🚀 Key Capabilities

• Dead Link (404/500) & Missing Image Discovery: Inspects hyperlinks (<a>) and embedded images (<img>) across internal site pages.
• Redirect Chain & Loop Tracking: Follows up to 5 redirect hops, flagging circular loops and insecure HTTP-to-HTTPS downgrade hops.
• Strict SSRF Defense: Hardened against Server-Side Request Forgery by rejecting private (RFC 1918), loopback, link-local, and cloud metadata IP ranges.
• Polite Crawling Engine: Parses robots.txt automatically and applies configurable polite delay intervals between page requests.

❓ High-Intent B2B FAQs

Q: How does this protect against SSRF vulnerabilities?

A: Every outbound DNS query resolves against an active firewall filter that blocks 127.0.0.1, 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16, and AWS/GCP instance metadata IP 169.254.169.254.

Q: Can I run this on a scheduled daily or weekly cron?

A: Yes. Use Apify Schedules, n8n, Make.com, or a standard curl webhook to trigger recursive site audits on any recurring cron cadence.

Q: Does it require browser rendering like Puppeteer or Playwright?

A: No. It utilizes a hyper-optimized HTTP engine that downloads only headers and lightweight HTML, saving 95%+ compute cost and completing audits in seconds. (Note: Single Page Applications where hyperlinks are injected exclusively via client-side JavaScript execution rather than server-rendered HTML will not have JS-rendered links crawled. For client-side dynamic JavaScript crawling, a headless Playwright Actor is recommended).
