Google Consent Mode v2: Why Your Advertising Data Can Suddenly Disappear

If Google Ads or Analytics data suddenly becomes incomplete, Consent Mode can be part of the reason. Websites need to send consent signals correctly, especially in the European market.

What Consent Mode v2 does

Consent Mode tells Google how a visitor handled cookie consent. Depending on that choice, Google adjusts tracking and modeling.

Why this matters for business

If consent is configured incorrectly, campaigns may lose conversion data, remarketing audiences may shrink and reports may become less useful.

Legal and technical layers

Consent Mode is not a legal policy by itself. You still need a proper cookie banner, privacy information and technical integration that matches your tools.

How to fix it in WordPress

  • Use a consent plugin that supports Consent Mode v2.
  • Verify Google tags and events.
  • Test consent states.
  • Document cookies and analytics tools.
