Not every website uses a third-party CMP — many have custom-built cookie consent banners or integrate consent into their own user account systems. We implement Google Consent Mode v2 for any custom consent solution: building the JavaScript consent signal bridge that reads your consent state and updates Google's consent signals appropriately, handling the full consent lifecycle (initial load, consent granted, consent withdrawn, page refresh with stored consent).

Frequently Asked Questions

Yes — you just need a mechanism that (a) collects user consent choice, (b) stores it, and (c) passes it to Google's consent commands. We build the integration bridge for your custom consent solution.
gtag('consent', 'default', {...}) sets initial state before any consent; gtag('consent', 'update', {...}) updates state after user interaction. We implement both in the correct order and timing.
Consent is typically stored in a cookie or localStorage. We implement storage using a first-party approach that persists across sessions and reads the stored state on page load before Google tags execute.
Yes — if your consent is managed server-side (stored in your database), we implement a server-rendered consent state injection that makes it available client-side for Consent Mode before tags load.
We can extend your banner to include granular consent options, or map a single yes/no choice to the appropriate consent signals based on your legal assessment.
