Google Says X-Frame-Options Matters For SEO via @sejournal, @martinibuster

Google's John Mueller stated on March 13, 2024, that X-Frame-Options is the sole security header directly impacting Search Engine Optimization (SEO). This clarification addresses a common point of confusion among webmasters regarding the influence of HTTP security headers on search engine rankings. Mueller emphasized that while other security headers are crucial for website protection, X-Frame-Options is specifically recognized by Google as having a discernible effect on SEO performance. The X-Frame-Options header controls whether a browser should be allowed to render a page in a <frame>, <iframe>, <embed>, or <object>. Properly configuring this header can prevent clickjacking attacks, a type of exploit where a malicious website tricks a user into clicking on something different from what the user perceives, thus indirectly safeguarding user experience and site integrity, which are factors considered in SEO. Search Engine Journal reported this statement, highlighting its significance for website administrators aiming to optimize their online presence.
