Technical Audit
Know what is broken before you scale traffic.
- 50+ high-impact checks across security, SEO, AI Crawler Access (robots.txt), DNS, and performance.
- Interactive AI-Crawler Emulation to watch, step by step, what external AI bots actually fetch from your live website.
- Prioritized findings by business impact, not just technical severity.
- Production-ready, copy-paste remediation code your team can ship immediately.
1. Technical Audit + AI Emulation
- Security headers, DNS health, and indexability signals in one pass.
- Live AI-Crawler Emulation for ChatGPT and Perplexity, including robots policy visibility.
- OpenGraph, sitemap, canonical, mobile readiness, and AI Crawler Access (robots.txt) checks.
- Clear fix order based on what moves traffic, trust, and conversions first.
Why do it: unresolved issues quietly drain rankings and revenue. The audit removes guesswork.
2. Asset Formatting
Every directory has different image requirements. Our engine automatically resizes your logo, crops your screenshots, and generates specific banners for ProductHunt, Twitter, and LinkedIn.
3. Headless Submission
Our fleet of headless browsers navigates the submission forms for you. We handle the login, the extensive questionnaires, and the captcha solving. You just watch the green checks appear.
The Old Way
Without SignalScan: You launch with a broken OpenGraph image and then spend 40 hours manually filling out 100 identical forms on directory sites. You forget half of them.
ERROR: 404 Submission Failed
The SignalScan Way
With SignalScan: You know 100% certainly that your tech is flawless. Then our bot does the submission work for you. You focus on the users.
