About This Tool - Bulk Security Header Checker
Use this tool to bulk-audit SEO and security headers across domains, subdomains, or international variations. It checks for best-practice implementation of headers like Strict-Transport-Security, X-Frame-Options, Content-Security-Policy, X-Robots-Tag, Referrer-Policy, and Permissions-Policy. Useful for pre-launch QA, compliance checks, or competitive benchmarking.
It’s particularly effective during migrations, sub-domain expansions, international environments or site consolidations, where consistency across environments matters. Results are exportable to CSV for sharing with developers, stakeholders, or embedding in audit documentation. Part of a growing suite of tools designed to simplify and scale technical SEO tasks that are often overlooked or time-consuming.
