Consent Mode v2: what a small business must have in place

If you advertise to UK visitors and use Google Ads measurement or remarketing, Google’s policy requires their consent. Consent Mode v2 passes each visitor’s choice to Google’s tags, for four settings. A cookie banner on its own does not pass the choice on.

Last updated 9 October 2026.

In short

  • Google’s EU user consent policy requires consent from visitors in the UK, the EEA and Switzerland. Google requires verified consent signals for EEA traffic, and says it does not expect them for UK traffic.
  • Version 2 sends 4 settings: ad_storage, analytics_storage, ad_user_data and ad_personalization.
  • Basic mode loads no Google tags until the visitor chooses; advanced loads them with consent denied and sends cookieless signals.

What does Consent Mode v2 send?

SettingWhat it covers
ad_storageCookies used for advertising
analytics_storageCookies used for analytics
ad_user_dataSending visitor data to Google for advertising
ad_personalizationPersonalised advertising, including remarketing

The last two settings were added in version 2. A setup that sends only the first two is out of date. Google lists all four in its consent mode overview.

Basic or advanced: which is right?

BasicAdvanced
Google tags before the visitor choosesDo not loadLoad, with consent set to denied
When the visitor declinesNothing is sent to GoogleAnonymous signals without cookies are sent
Conversions from visitors who declineNot countedEstimated by Google from the anonymous signals

Advanced gives Google more to bid with. Basic sends less data. Which is right depends on your own privacy position; your privacy notice should describe the one you use.

What must be in place?

  1. A cookie banner that offers Reject as clearly as Accept.
  2. All four settings default to denied before any Google tag fires.
  3. The banner updates all four settings when the visitor chooses.
  4. A test in Google Tag Assistant shows the consent state changing on accept and on reject.
  5. The privacy notice explains what is collected and why.
