Introduction
Cookieless analytics has emerged as the solution to this data loss crisis. Unlike traditional cookie-based platforms like Google Analytics — which lose the visitors who ghost or reject the banner — cookieless analytics measures that traffic without consent banners, cookies, or personal identifiers like IP addresses.
This complete guide explains how cookieless analytics works, how it is designed to comply with the GDPR without consent, and how platforms like Sealmetrics provide businesses with accurate, complete data while respecting user privacy.
Key Takeaways
- Cookieless analytics measures the traffic the banner loses, without cookie consent banners, closing the consent gap
- No consent banner needed on Sealmetrics' own assessment: nothing is written to the device, nothing stored identifies anyone, and the session identifier, which rotates daily and then cannot be reconstructed, is assessed against the audience-measurement exemption of ePrivacy Article 5(3). In Germany this is an open question — see Germany
- Session-based tracking replaces cookies with temporary identifiers that reset after each visit
- Sealmetrics provides true cookieless analytics without storing IP addresses (unlike competitors)
