How do you check that Google Consent Mode v2 is correctly configured on your site?

Open your site in an incognito window with DevTools on the Network tab and look for the gcs and gcd parameters on requests to Google domains: before any click the state must be "denied", and after accepting a new request must appear with the updated state. If you would rather not read network requests, the free FewCookies scan automatically checks the default state, the default → update order and which trackers fire before consent.

What is Google Consent Mode v2 and how do you implement it correctly?

Google Consent Mode v2 is the mechanism through which your site sends Google four consent signals — ad_storage, analytics_storage, ad_user_data and ad_personalization — before and after the visitor decides. Since March 2024 it is required for any site with an EEA audience that uses Google remarketing or ad personalization. It does not replace your cookie banner: it presumes one that sets the default state to "denied" before gtag loads and sends the update right after the choice.
