What this checks

Under UK GDPR and PECR, non-essential cookies need consent before they are set. This shows what your page sets on a plain first request, which is the state a visitor is in before they touch a consent banner.

  • Every cookie set on the response
  • Secure flag
  • HttpOnly flag
  • SameSite attribute

How to act on the result

  • Analytics and marketing cookies set before consent are a compliance problem, not a technical one.
  • Session cookies should carry Secure and HttpOnly.
  • SameSite=Lax is a sensible default.

Frequently asked

Which cookies need consent?

Anything not strictly necessary to deliver a service the user asked for. Analytics and advertising cookies need consent. A cookie remembering the contents of a basket generally does not.

Does a cookie banner make me compliant?

Only if it actually blocks non-essential cookies until consent is given. Many banners are decorative and the cookies fire regardless, which is worse than no banner because it documents intent.

What do Secure and HttpOnly do?

Secure sends the cookie only over HTTPS. HttpOnly hides it from JavaScript, which limits the damage from a cross-site scripting flaw.

Do cookies affect SEO?

No. This check is here for compliance and security, not rankings.
