Free Online Security Headers Generator & Config Tool
Generate robust HTTP security headers instantly for Apache, Nginx, and Netlify to improve your website's security score and SEO trustworthiness.
Why HTTP Security Headers Matter for Technical SEO
When optimizing a website for search engines, technical SEO goes far beyond keyword placement and meta tags. Search engine crawlers, such as Googlebot, heavily prioritize user security, data privacy, and overall site integrity. Implementing strong HTTP security headers protects your web visitors from cross-site scripting (XSS), clickjacking, and MIME-sniffing attacks, contributing to a trustworthy user experience that search algorithms favor.
Key Security Headers Included in This Generator
Our free online security headers generator automates the creation of production-ready configuration snippets for both Nginx and Apache web servers. Here is a breakdown of the critical directives generated:
- Strict-Transport-Security (HSTS): Forces browsers to interact with your website exclusively over secure HTTPS connections, preventing man-in-the-middle attacks.
- X-Frame-Options: Defends your web pages against clickjacking by controlling whether your site can be embedded within an iframe on external domains.
- X-Content-Type-Options: Stops browsers from MIME-sniffing away from the declared content-type, ensuring files are interpreted safely.
- Referrer-Policy: Controls how much referrer information should be included with requests, balancing analytics needs with user privacy.
- Permissions-Policy: Restricts the usage of powerful browser APIs like geolocation, camera, and microphone across your web application.
How to Apply These Headers to Your Web Server
Once you use our interactive tool to select your preferred configuration, simply copy the generated snippet and paste it directly into your server configuration files:
- For Nginx: Paste the generated
add_headerdirectives inside yourserver {}orlocation {}block, then restart your Nginx service. - For Apache: Paste the
Header always setdirectives into your main server configuration or directly inside your root.htaccessfile.
After deploying these headers, test your website using platforms like Mozilla Observatory or SecurityHeaders.com to verify your security score and ensure your SEO foundation remains uncompromised.
