Understanding Cookie Usage: What These Numbers Mean
Cookies are small data files stored in your browser when you visit a website. While some cookies are essential for website functionality (session management, preferences), many serve advertising and tracking purposes. The websites on this list set an unusually high number of cookies on the first page load, before any user interaction or consent.
First-Party vs Third-Party Cookies
First-party cookies are set by the domain you're visiting and typically handle session state and preferences. Third-party cookies are set by external domains (advertisers, analytics providers, social networks) and enable cross-site tracking. The most concerning entries on this list tend to have a high ratio of third-party to first-party cookies, indicating extensive data sharing with external entities.
GDPR and Cookie Consent
Under the ePrivacy Directive and GDPR, non-essential cookies require informed user consent before being set. Websites that set dozens of cookies before showing a consent banner are likely non-compliant. For vendor risk teams, this is a measurable indicator of a vendor's regulatory compliance posture. Our scanner detects cookies set during the initial page load, which represents the pre-consent state most users experience.
Cookie Lifetime and Persistence
Beyond count, cookie lifetime matters. Some tracking cookies persist for years, maintaining a persistent identifier across browsing sessions. Session cookies expire when the browser closes and are generally less concerning. Our detailed domain reports break down cookie purposes and lifetimes, giving compliance teams the full picture of a vendor's cookie practices.
Using Cookie Data for Vendor Assessment
A high cookie count on a vendor's website suggests they either monetize user data through advertising or lack the engineering discipline to manage their cookie footprint. Both scenarios are relevant for vendor due diligence. Our Domain Intelligence API provides cookie analysis data programmatically, enabling integration into your vendor risk scoring models and automated compliance monitoring workflows.
How We Count Cookies
Gecko Advisor counts cookies by loading each website in a clean headless browser session with no prior browsing history or cookies. We record all cookies set during the initial page load and categorize them by domain (first-party vs third-party), purpose (essential, analytics, advertising), and lifetime (session vs persistent). This methodology captures the default cookie behavior a new visitor would experience.
