Because the script now comes from your own domain, browsers and ad blockers are **less likely to block it**, so you recover more ad and analytics measurement. The most common way to turn it on is the **one-click setup in Google Tag Manager using Cloudflare**. ## What does "late consent" mean? Google Consent Mode works by reading your visitors' consent choices **before** any Google tag is allowed to run. Consentmo does this by setting the Consent Mode **default** state (everything denied) the moment the page loads, *before* your Google tags fire. A **"late consent" signal** happens when a Google tag reads or fires **before** Consentmo has set that default state. Google's own guidance is clear: *if the consent default is set out of order, consent defaults won't work.* **Why it matters:** Google may treat those signals as non-compliant, which can reduce your conversion measurement and remarketing eligibility — and it counts against your store in privacy audits. **Why Google Tag Gateway often causes it:** with the one-click Cloudflare setup, Google's infrastructure decides when the tag loads — often **before** your cookie banner script runs. When that happens, the tag starts working before Consentmo can set the consent default. ## How do I know if I'm affected? Consentmo checks this for you automatically. 1. In the Consentmo app, go to **Integrations → Google Consent Mode V2**. 2. Click **Check status** (the Integration Checker). 3. If Consentmo detects a late consent signal, you'll see a warning banner titled **"Possible late consent signal detected"**, with the steps below. The two checks that trigger this warning are: * **"Defaults applied correctly"** fails → consent defaults were set too late (or not at all). * **"No GA4/Ads hits before consent"** fails → Google tags sent data before the visitor consented. ## Step 1 — Check whether Google Tag Gateway is enabled Before changing anything, confirm GTG is actually on (it's the most common cause). **Check in Google Tag Manager:** 1. Sign in to [Google Tag Manager](https://tagmanager.google.com/). 2. Click **Admin** in the top navigation. 3. Under your container settings, look for **Google tag gateway**. If it's configured (you'll see a measurement path), GTG is enabled. **Or check in Cloudflare:** 1. Sign in to the [Cloudflare dashboard](https://dash.cloudflare.com/). 2. Select your domain → open the **Google Tag Gateway** page. 3. If the toggle is on, GTG is enabled for your site. **Or check on your live store:** open your storefront, open the browser's **Network** tab, and reload. If GA4/Ads/GTM requests are served from **your own domain** (not `googletagmanager.com`), GTG is active. ## Step 2 — Fix the late consent signal (recommended path) > **Google's recommended fix for GTG-enrolled stores is Advanced Consent Mode.** With one-click GTG, you can't control when the tag loads, and Advanced Consent Mode is the only option that works regardless of load order — tags load in a restricted, cookieless state and update the moment the visitor chooses. ### 2a. Turn on Advanced Consent Mode in Consentmo 1. In Consentmo, go to **Integrations → Google Consent Mode V2**. 2. Make sure the integration is **enabled** and your GTM / GA4 / Google Ads IDs are filled in. 3. Under **Consent mode type**, select **Advanced** (recommended). 4. **Save** your changes. ### 2b. Enable Data Transmission Controls in Google Tag Manager 1. Sign in to [Google Tag Manager](https://tagmanager.google.com/). 2. Go to **Admin → Container Settings** (or **Consent Settings**). 3. Enable **Data Transmission Controls**. ### 2c. Set Global Consent Defaults for your regions 1. Still in Google Tag Manager, configure **Global Consent Defaults** so that ad and analytics storage are **denied by default** in the regions where you require consent (e.g. EEA/UK). 2. Set these according to your own regional compliance requirements. > Official Google reference: **Set up Consent Mode** — [https://developers.google.com/tag-platform/security/guides/consent](https://developers.google.com/tag-platform/security/guides/consent) and **About Advanced Consent Mode** — [https://developers.google.com/tag-platform/security/concepts/consent-mode](https://developers.google.com/tag-platform/security/concepts/consent-mode) ## Step 3 — Verify the fix worked 1. Save all changes in Consentmo and Google Tag Manager, then **publish** your GTM container. 2. Return to Consentmo → **Integrations → Google Consent Mode V2**. 3. Click **Check status** again. 4. The **"Defaults applied correctly"** and **"No GA4/Ads hits before consent"** checks should now pass, and the late consent warning should disappear. If the warning persists, double-check that GTM was **published** (not just saved) and try one of the alternative fixes below. ## Alternative fixes If Advanced Consent Mode isn't an option for your setup, you can instead: * **Route all Google tags through a GTM container.** When every Google tag is managed by GTM, GTM applies the consent defaults before any tag fires. * **Use a manual Google Tag Gateway deployment** instead of the one-click Cloudflare CDN injection. A manual deployment lets you control script order, so you can ensure Consentmo's banner loads and sets consent defaults **before** the Google tag script. Google's setup reference: [https://developers.google.com/tag-platform/tag-manager/gateway/setup-guide](https://developers.google.com/tag-platform/tag-manager/gateway/setup-guide) ## FAQ **Do I have to turn off Google Tag Gateway?** No. GTG is good for measurement recovery. You just need consent handled correctly — Advanced Consent Mode (Step 2) does this without disabling GTG. **Is Advanced Consent Mode less private?** No. Tags load in a **restricted, cookieless** state and only collect full data **after** the visitor grants consent. Until then, Google receives privacy-safe signals only. **I don't use Google Tag Gateway — why am I seeing this warning?** Late consent can also come from other tags loading before the banner, an asynchronous theme script, or a Google tag added directly in your theme. Make sure Consentmo manages your Google tags (don't also add them manually in the theme), then re-run the checker. **Where do I change the consent mode type?** Consentmo → **Integrations → Google Consent Mode V2 → Consent mode type → Advanced**. **Still stuck?** Contact Consentmo support with your store URL and a screenshot of the Integration Checker result, and we'll help you confirm the setup. # Appendix — References and documentation **Consentmo documentation** * [Google Consent Mode V2 (GCM V2)](https://support.consentmo.com/en/article/google-consent-mode-v2-gcm-v2-automatic-integration-4tnbts/) * [GCM V2 customization options](https://support.consentmo.com/en/article/gcm-v2-customization-options-137fv8c/) **Google documentation** * [GTG main page](https://developers.google.com/tag-platform/tag-manager/gateway) * [Google Tag Manager help center](https://support.google.com/tagmanager) * [Consent Mode — Tag Platform](https://developers.google.com/tag-platform/security/guides/consent) * [Consent Mode — product overview](https://support.google.com/analytics/answer/9976101) * [Advanced consent mode — technical reference](https://developers.google.com/tag-platform/security/guides/consent?consentmode=advanced) * [Data Transmission Controls](https://support.google.com/google-ads/answer/16054531) The Google pages above are authoritative sources.
