# Incorrect data layer name #### Description At least one Google service detected on the page **is not using the default data layer name `dataLayer`**. This may cause inconsistencies when triggering tags or passing consent signals — especially if multiple data layers exist or if the CMP does not communicate with the correct global object. #### Possible causes * One or more Google tags (Google Ads, Google Analytics, etc.) are configured to use a **custom data layer name** (e.g., `myDataLayer`, `gtmDataLayer`, etc.). * If the CMP is **not loaded via Google Tag Manager**, it assumes the default name is `dataLayer` unless specified otherwise. #### What to do **Recommended solution:** * **Use a consistent data layer name** across the entire website (ideally `dataLayer`, unless a different name is strictly required). **If you intentionally use a custom data layer name and your CMP is not loaded via GTM:** * Declare the correct name **before the CMP is loaded**, using the following line:

<script>
    window.ABconsentCMP = window.ABconsentCMP || {};
    window.ABconsentCMP.gtmDataLayerName = "NOM_DU_DATALAYER_PERSONNALISÉ";
