What does the Website Discovery scanner detect?

GA Auditor examines the technologies and browser activity visible when a public webpage loads. The report helps marketers, analysts, developers, and privacy teams quickly understand a website's measurement and marketing technology stack without requiring access to its source code, analytics account, or tag manager container.

Analytics and tag management

Identify commonly observed analytics tools, Google Analytics measurement IDs, Google Tag Manager containers, and other browser-based measurement technologies.

Advertising and marketing platforms

Find advertising pixels, conversion tags, customer experience tools, session recording products, and other marketing services detected during the scan.

Cookies and consent signals

Review cookies created during the initial page load, their observed attributes, and signals associated with consent management and Google Consent Mode.

CSP and third-party resources

See whether a Content Security Policy was observed and review third-party domains, resource types, CSP directives, and browser-reported policy behavior.

How the website scanner works

  1. Enter the full URL of a publicly accessible webpage.
  2. The scanner loads the page in a browser environment and observes its initial network and document activity.
  3. GA Auditor organizes the observed technologies, cookies, security policy information, and third-party resources into a readable report.

How to interpret the results

Discovery results describe what was observed; they are not automatically errors, compliance findings, or proof that a tool is configured correctly. Technologies loaded after login, consent, scrolling, form submission, or other interaction may not appear in an initial-page scan. Use the report as a starting point for a deeper analytics, privacy, performance, or security review.

Website scanner FAQs

Can this scanner detect Google Analytics and Google Tag Manager?

It can identify commonly observed GA4 measurement IDs, Google Tag Manager containers, and related browser requests when they are present during the scanned page load.

Does the scanner change the website?

No. Website Discovery performs an observational scan of a public page and does not modify the scanned website or its configuration.

Why might a technology be missing?

A technology may load only after consent, user interaction, authentication, a specific campaign visit, or navigation to another page. Some websites also restrict automated browsers or third-party requests.

Is the report a compliance or security certification?

No. The report provides observed technical information for review. It is not legal advice, a vulnerability assessment, or a certification of privacy, security, or regulatory compliance.
