Tracking visibility problem

Websites often load more tracking than teams realize

Marketing, analytics, support, ecommerce, and optimization tools can introduce third-party scripts and requests that are difficult to understand from a cookie list alone.

Marketing tools change quickly

Pixels, tags, scripts, GTM rules, ad campaigns, and vendor tools can change website behavior over time.

Consent does not always mean control

Teams may need to understand what happens before and after accept, reject, or opt-out choices.

Third-party requests are easy to miss

A website may contact ad platforms, analytics tools, chat tools, session tools, and apps during user flows.

Privacy teams need evidence

Cookie lists alone may not show request timing, affected pages, screenshots, or consent-state differences.

Evidence differentiation

Observed third-party request behavior, not just a cookie list

A basic cookie list may show names of cookies. A pixel tracking audit should also help teams understand which third-party domains are contacted and when requests happen.

Auditzo documents selected page context, flow context, request behavior, consent-state differences, screenshots, timestamps, and remediation-oriented notes where included in scope.

View Manual Evidence Audit

Observed request behavior can include

  • Third-party domains contacted
  • Scripts loaded by the website
  • Pixel and tag requests
  • Analytics and advertising requests
  • Browser storage behavior
  • Cookie creation timing
  • Request behavior on key pages
  • Request behavior during form, cart, or checkout flows where scoped
  • Initial, accept, reject, or opt-out comparisons where scoped
  • Screenshots and timestamps for selected observations
  • Affected URLs and page context
  • Remediation-oriented technical notes
Consent-state testing

Cookie and consent-state pixel behavior

Many teams need to know whether pixels, tags, or requests appear before a user makes a consent choice, after accepting, after rejecting, or after using opt-out controls.

Consent-state review depends on approved scope, website behavior, available banner controls, and testing conditions.

View Cookie Audit Tool

Consent-state review can include

  • Cookie banner visibility
  • Initial page load behavior
  • Accept state behavior
  • Reject state behavior
  • Opt-out or preference center behavior
  • Cookie creation before and after choices
  • Pixel requests before and after choices
  • Browser storage differences
  • Third-party domains contacted in each state
  • Consent-state comparison notes
  • Screenshots and timestamps
  • Page and flow context
