Cookies are small text files stored in your browser when you visit a website. They help the site remember your preferences and actions. SERP.tools uses only a small number of strictly necessary and optional analytics cookies — no advertising cookies, no tracking for third-party ad networks.

SERP.tools (Cloudflare Worker)

Set at the network edge by our Cloudflare Worker. Contains EU or WORLD based on your country. Used to decide whether to show the consent banner (EU/EEA/UK/CH users) or auto-accept (everyone else). Expires in 1 hour.
No
Note on GA4 and cookieless mode: Even if you decline analytics cookies, Google Analytics still sends anonymous, cookieless pings under GA4 Advanced Consent Mode. These do not identify you individually and help us model aggregate traffic patterns without storing any data on your device.
Your choices
You have full control over analytics cookies:
Change your choice at any time: Click the link in the site footer (or click here). The banner will reappear and you can update your choice.
Browser settings: You can block or delete cookies in your browser settings. Note that blocking essential cookies will prevent login from working.
PostHog opt-out: Declining analytics cookies via the banner prevents PostHog from running. PostHog is configured to opt_out_capturing_by_default — it never runs unless you explicitly accept.
Local storage
In addition to cookies, SERP.tools uses localStorage to store your consent preference (cookie_consent). This is stored on your device only and is never transmitted to our servers. You can clear it via the Cookie settings link above or through your browser's developer tools.
