Security & Infrastructure
RankCore.ai
Role: Solo technical lead — infrastructure diagnostics and remediation.
1. Challenge
A live backlink-intelligence SaaS was suffering a silent, severe SEO regression — search engine crawlers, including Googlebot and PageSpeed Insights, were being blocked at the edge without any obvious application-level error.
2. Business Requirements
- Restore full crawler accessibility without exposing the site to actual bot abuse.
- Fix the underlying authentication misconfiguration surfaced during the investigation.
- Ensure the fix was durable, not a temporary workaround.
3. Proposed Architecture
Used a layered edge-security review — DNS/proxy settings, edge security mode, and platform-level bot-challenge rules — to isolate exactly which layer was blocking legitimate automated traffic.
4. Implementation Approach
Systematically ruled out application-level causes before identifying the edge security layer as the source, then applied a targeted, scoped fix (a firewall allow-rule for known-good crawlers) rather than disabling protection broadly.
5. Security Considerations
Balanced restoring legitimate crawler access against maintaining meaningful bot protection — the fix was scoped to known-good crawler traffic rather than a blanket relaxation of edge security.
6. Results
Crawler access and SEO scoring were restored after root-causing the issue to an edge-security misconfiguration rather than an application bug.
