原文外掛簡介
VGDev Cookie Banner for Consent Mode v2 is a lightweight, self-hosted GDPR cookie consent solution that integrates natively with Google Consent Mode v2, Google Tag Manager (GTM) and Google Analytics 4 (GA4).
All consent signals start as denied and are updated in real time based on the visitor’s choices — fully compliant with Google’s requirements for EU markets.
Key Features
✅ Google Consent Mode v2 — all 7 consent signals managed automatically
✅ Google Tag Manager (GTM) — head snippet + body noscript injected automatically
✅ Google Analytics 4 (GA4) — standalone gtag.js support (when GTM is not used)
✅ GDPR Compliant — consent defaults to denied before any tracking occurs
✅ Multilingual Privacy Policy — set a different privacy policy URL per language
✅ 29 built-in languages — auto-detected via WPML, Polylang or WordPress locale
✅ Performance Mode — lazy loads the banner after user interaction (boosts PageSpeed score)
✅ Force Consent — block the page until the user makes a choice
✅ Fully customizable — colors, layout, position, floating button, and more
✅ Self-hosted — no external consent management platform needed
✅ Lightweight — no jQuery dependency for the front-end script
Google Consent Mode v2 Signals
The plugin manages all required consent signals:
ad_storage
ad_user_data
ad_personalization
analytics_storage
functionality_storage
personalization_storage
security_storage
Consent Categories
Necessary → security_storage
Functionality → functionality_storage, personalization_storage, security_storage
Analytics → analytics_storage, security_storage
Marketing → ad_storage, ad_user_data, ad_personalization, personalization_storage
Multilingual Support
Works out of the box with WPML, Polylang and WordPress locale. You can also set per-language privacy policy URLs so visitors always see the privacy page in their own language.
Performance Mode
Enable lazy loading to load the cookie banner only after the first user interaction (scroll, click, mouse move or touch). Since Google PageSpeed Insights does not simulate interactions, the banner will not appear in the performance audit — significantly improving your Core Web Vitals score.
Built-in Languages
English, Greek, German, French, Spanish, Italian, Portuguese, Dutch, Polish, Czech, Slovak, Hungarian, Romanian, Bulgarian, Croatian, Serbian, Slovenian, Estonian, Latvian, Lithuanian, Finnish, Swedish, Danish, Norwegian, Russian, Ukrainian, Chinese, Japanese, Arabic.
External Services
This plugin connects to external services provided by Google when the site administrator configures a Google Tag Manager (GTM) Container ID or a Google Analytics 4 (GA4) Measurement ID in the plugin settings.
Google Tag Manager (GTM)
When a GTM Container ID is entered in the plugin settings, the plugin loads the Google Tag Manager JavaScript snippet from Google’s servers. This happens on every front-end page load.
What it does: Loads the GTM container script so that tags configured inside GTM (analytics, advertising, etc.) can fire according to consent status.
What data is sent: The GTM Container ID and standard browser information (IP address, user agent, page URL, referrer) are sent to Google’s servers when the script is loaded. Additional data may be collected depending on the tags configured within GTM by the site administrator.
When it is sent: On every front-end page load, after the consent defaults have been set.
Service provider: Google LLC
Terms of Service: https://www.google.com/analytics/terms/tag-manager/
Privacy Policy: https://policies.google.com/privacy
Google Analytics 4 (GA4) via gtag.js
When a GA4 Measurement ID is entered and no GTM Container ID is configured, the plugin loads the Google Analytics gtag.js script from Google’s servers.
What it does: Loads the GA4 measurement script to collect website analytics data (page views, events, etc.) according to consent status.
What data is sent: The GA4 Measurement ID and standard browser information (IP address, user agent, page URL, referrer) are sent to Google’s servers. Analytics data (page views, session data, events) is only collected according to the visitor’s consent choices.
When it is sent: On every front-end page load, after the consent defaults have been set. Actual analytics data collection depends on user consent.
Service provider: Google LLC

Note: No data is sent to any external service by this plugin unless the site administrator explicitly configures a GTM Container ID or GA4 Measurement ID. The cookie consent preferences are stored locally in the visitor’s browser and are not transmitted to any external server.
