Frequently Asked Questions
What are HTTP response headers?▼
HTTP response headers are metadata sent by a web server along with the requested content. They tell the browser and search engines how to handle the response — including caching rules, content type, security policies, and redirect instructions.
Which HTTP headers are important for SEO?▼
Key SEO headers include X-Robots-Tag (indexing directives), Link (canonical URL), HTTP status code (200, 301, 404), Cache-Control (caching behavior), Content-Type (MIME type), and Vary (content negotiation). These affect how search engines crawl and index your pages.
What does the X-Robots-Tag header do?▼
The X-Robots-Tag is an HTTP header that provides indexing directives to search engines, similar to a meta robots tag but at the HTTP level. It can include values like noindex, nofollow, noarchive, and nosnippet. It is useful for non-HTML resources like PDFs.
How do I add security headers to my website?▼
Security headers are typically configured in your web server (Apache, Nginx) or CDN settings. Key security headers include Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, Strict-Transport-Security, and Referrer-Policy. Many hosting platforms also provide UI controls for these.
