X-Frame-Options header missing: what it is, why it matters, and how to fix it
This site does not send the X-Frame-Options HTTP header, which controls whether the page can be embedded in iframes on other domains. Without it, the page is vulnerable to clickjacking attacks.
Where this fits: security in SEO
Why x-frame-options header missing hurts your rankings
Clickjacking attacks overlay your page in a transparent iframe, tricking users into clicking elements on your site while believing they are interacting with another site. This can lead to unauthorized actions, data theft, and account compromise. A security breach can result in Google Safe Browsing warnings that devastate organic traffic.
This is a medium-severity issue: individually modest, but it compounds — dozens of medium issues across hundreds of pages add up to a real quality deficit in how search engines assess the site.
How to fix it
Add the X-Frame-Options header to your server responses. Use DENY to prevent all framing, or SAMEORIGIN to allow framing only from your own domain. For more granular control, use the Content-Security-Policy frame-ancestors directive.
# Prevent framing entirely
