<h4>Consent Management</h4>
<p>Auto-detection and integration patterns vary by CMP; you remain responsible for correct legal configuration on your site.</p>
<h4>Google Tag Manager</h4>
<p>Optional <strong>snippet</strong> + consistent <strong>dataLayer</strong> pushes. Configure tags, triggers, and variables inside GTM.</p>
<h3>External Services</h3>
<h4>Google Tag Manager (optional — only when you configure a container ID)</h4>
<p>This plugin includes an optional feature to inject the Google Tag Manager container snippet on your site’s front end. This feature is <strong>disabled by default</strong> and only activates when you enter a GTM Container ID in the plugin settings and enable the snippet toggle.</p>
<p><strong>What it does:</strong> When enabled, the plugin outputs the standard GTM <code><script></code> and <code><noscript></code> tags that load <code>https://www.googletagmanager.com/gtm.js</code>. This causes the visitor’s browser to contact Google’s servers to load the GTM container.</p>
<p><strong>What data is sent:</strong> When GTM loads, Google receives the visitor’s IP address, browser, and the URL being viewed — the same data sent by any website that loads GTM. No additional data is sent by this plugin beyond the standard GTM request. The plugin itself populates <code>window.dataLayer</code> in the browser; it is your GTM configuration that determines what analytics data leaves the site.</p>
<p><strong>When it is sent:</strong> Only on front-end page loads when the visitor’s browser downloads the GTM script. If the consent-delay feature is enabled, the snippet is withheld until the visitor grants consent via your CMP.</p>

</ul>
<h4>WordPress Admin AJAX</h4>
<p>All plugin settings saves, the setup wizard, and admin actions use WordPress’s built-in <code>admin-ajax.php</code> endpoint. All requests go to your own WordPress installation. No data is sent to external servers by these requests.</p>
<p><strong>Important:</strong> You are responsible for ensuring that any third-party analytics services (GTM, GA4, etc.) you configure on your site comply with applicable data-protection laws (GDPR, CCPA, etc.) and that visitors are properly informed. This plugin provides consent-delay and CMP-detection functionality to help withhold scripts until consent is obtained, but legal compliance remains your responsibility.</p>
<h3>Privacy Policy</h3>
<p>BrandMeetsCode DataLayer Tracker may expose, depending entirely on which options you enable:</p>
<ul>
<li>Page URL, titles, and taxonomy-style context</li>
<li>Logged-in user fields you choose to surface, including optional <strong>hashed</strong> identifiers</li>
<li>Engagement signals (scroll depth, timing, generic form interactions)</li>
<li>WooCommerce-related item data when ecommerce tracking is enabled</li>
<li>Structured event data pushed to <code>window.dataLayer</code> for use by analytics tools you configure</li>
</ul>
<p>This plugin does not send data to any external server on your behalf. You are responsible for consent, disclosure, and lawful basis for any analytics tools you add to your site. The plugin does not replace legal or DPO review.</p>
<p>Data is exposed to the browser <code>dataLayer</code>; downstream tags decide what leaves the site.</p>

BrandMeetsCode DataLayer Tracker

GTM-ready dataLayer: consent-aware events, engagement, admin debug overlay, optional WooCommerce. Fully free—no license keys or locked settings.

Thomas Geiger

<p>Google Tag Manager (GTM) is Google’s free tool for everyone to manage and deploy analytics and marketing tags as well as other code snippets<br />
using an intuitive web UI. To learn more about this tool, visit the <a href="https://marketingplatform.google.com/about/tag-manager/" rel="nofollow ugc">official website</a>.</p>
<p>This plugin places the GTM container code snippets onto your WordPress website so that you do not need to add it manually.<br />
Multiple containers are also supported!</p>
<p>The plugin complements your GTM setup by pushing page meta data and user information into the so called data layer.<br />
Google’s official help pages includes <a href="https://developers.google.com/tag-platform/tag-manager/datalayer#datalayer" rel="nofollow ugc">more details about the data layer</a>.</p>
<p><strong>PHP 7.4 is required to use this plugin.</strong></p>
<h4>GTM container code placement</h4>
<p>The original GTM container code is divided into two parts:</p>
<p>The first part is a javascript code snippet that is added to the <code><head></code> section of every page of the website.<br />
This part is critical to enable all features of GTM, and this plugin helps to place this part<br />
correctly on your site.</p>
<p>The second part is an iframe snippet that acts as a failsafe/fallback should users’ JavaScript be disabled.<br />
Google recommends – for best performance – to place this code snippet directly after the opening <code><body></code> tag on each page.</p>
<p>Albeit not ideal, it will work when placed lower in the code. This plugin provides a code placement option for the second code snippet.</p>
<p>If your WordPress theme is compatible with the additions of WordPress 5.2 then this plugin will place this second code to the right place.<br />
Users of the Genisis theme, GeneratePress theme, Elementor, Oxygen Builder and Beaver Builder Theme will also have this placed correctly.<br />
To utilize this, set the compatibility mode in plugin options to off.</p>
<p>All other users can place this second code snippet using a custom PHP code (“Manually coded” option) or select the so called “Footer” option to<br />
add the code lower in the code (it is not the recommended way but will work)</p>
<h4>Basic data included</h4>
<ul>
<li>post/page titles</li>
<li>post/page dates</li>
<li>post/page category names</li>
<li>post/page tag names</li>
<li>post/page author ID and name</li>
<li>post/page ID</li>
<li>post types</li>
<li>post format</li>
<li>post count on the current page + in the current category/tag/taxonomy</li>
<li>custom terms associated with any post type</li>
<li>logged in status</li>
<li>logged in user role</li>
<li>logged in user ID (to track cross device behaviour in Google Analytics)</li>
<li>logged in user email address (both unhashed and SHA256 hased values to be used with tracking)</li>
<li>logger in user creation date</li>
<li>site search data</li>
<li>site name and id (for WordPress multisite instances)</li>
<li>IP address of the visitor (please use the explicit consent of the visitor to utilize this)</li>
</ul>
<h4>Browser / OS / Device data</h4>
<ul>
<li>browser data (name, version, engine)</li>
<li>OS data (name, version)</li>
<li>device data (type, manufacturer, model)</li>
</ul>
<p>Data is provided using the WhichBrowser library: http://whichbrowser.net/</p>
<h4>Weather data</h4>
<p>(beta)</p>
<p>Push data about users’ current weather conditions into the dataLayer. This can be used to generate weather-related<br />
audience/remarketing lists on ad platforms and allows for user segmentation in your web analytics solutions:</p>
<ul>
<li>weather category (clouds, rain, snow, etc.)</li>
<li>weather description: more detailed data</li>
<li>temperature in Celsius or Fahrenheit</li>
<li>air pressure</li>
<li>wind speed and degrees</li>
</ul>
<p>Weather data is queried from Open Weather Map. Depending on your websites traffic, additional fees may apply:<br />
http://openweathermap.org/price</p>
<p>An (free) API key from OpenWeatherMap is required for this feature to work.</p>
<p>ipstack.com is used to determine the site visitor’s location. A (free) API key from IPStack.com is required for this feature to work:<br />
https://ipstack.com/product</p>
<h4>Media player events</h4>
<p>(experimental)</p>
<p>Track users’ interaction with any embedded media:</p>
<ul>
<li>YouTube</li>
<li>Vimeo</li>
<li>Soundcloud</li>
</ul>
<p>DataLayer events can be chosen to fire upon media player load, media is being played, paused/stopped and optionally when<br />
the user reaches 10, 20, 30, …, 90, 100% of the media duration.</p>
<p>Tracking is supported for embedded media using the built-in oEmbed feature of WordPress as well as most other media plugins<br />
and copy/pasted codes. Players injected into the website after page load are not currently supported.</p>
<h4>Scroll tracking</h4>
<p>Fire tags based on how the visitor scrolls from the top to the bottom of a page.<br />
An example would be to separate “readers” (who spend a specified amount of time on a page) from “scrollers”<br />
(who only scroll through within seconds). You can use these events to fire Analytics tags and/or remarketing/conversion tags<br />
(for micro conversions).</p>
<p>Scroll tracking is based on the solution originally created by</p>
<ul>
<li>Nick Mihailovski</li>
<li>Thomas Baekdal</li>
<li>Avinash Kaushik</li>
<li>Joost de Valk</li>
<li>Eivind Savio</li>
<li>Justin Cutroni</li>
</ul>
<p>Original script:<br />
http://cutroni.com/blog/2012/02/21/advanced-content-tracking-with-google-analytics-part-1/</p>
<h4>Blacklist & Whitelist Tag Manager tags, triggers and variables</h4>
<p>To increase website security, you have the option to white- and blacklist tags/triggers/variables.<br />
You can prevent specific tags from firing or the use of certain variable types regardless of your GTM setup.</p>
<p>If the Google account associated with your GTM account is being hacked, an attacker could easily<br />
execute malware on your website without accessing its code on your hosting server. By blacklisting custom HTML tags<br />
and/or custom JavaScript variables you can secure the Tag Manager container.</p>
<h4>Integration</h4>
<p>Google Tag Manager for WordPress integrates with several popular plugins. More integration to come!</p>
<ul>
<li>Contact Form 7: fire an event when a Contact Form 7 form was submitted with any result (mail sent, mail failed, spam detected, invalid input)</li>
<li>WooCommerce:
<ul>
<li>Implementation of <a href="https://developers.google.com/tag-manager/ecommerce-ga4" rel="nofollow ugc">GA4 E-commerce</a></li>
<li>Does not support promotions since WooCommerce does not have such a feature (yet)</li>
<li>Does not support refunds</li>
<li>Compatibility with High Performance Order Storage (HPOS)</li>
</ul>
</li>
<li>AMP: load your AMP container on the AMP version of your pages</li>
<li>Cookiebot: use automatic cookie blocking mode if needed</li>
<li>Google Consent Mode v2: fire the “default” command with specific consent flags to integrat with non-certified Consent Management Platforms (CMPs) and plugins.</li>
</ul>
<h4>Server side containers</h4>
<p>If you are using a <a href="https://developers.google.com/tag-manager/serverside/send-data#update_the_gtmjs_source_domain" rel="nofollow ugc">server side container</a><br />
you can enter your custom domain name and custom path to load gtm.js from your there.</p>
<h4>Exclude specific user roles from being tracked</h4>
<p>You can set which user roles needs to be excluded from tracking when a user with that role visits the frontend. This will completely disable the container code for that user.</p>


GTM4WP – A Google Tag Manager (GTM) plugin for WordPress

The plugin worked well but then an issue is caused with another plugin. I offered my help to troubleshoot this but there is no response in weeks in the support forum. Also to other threads than mine.

No support since weeks

Working as expected.


I’m disappointed with the support for this plugin. I submitted a question over a week ago, but I have yet to receive any response from the support team.



While the plugin itself may work fine, having reliable support is critical, especially when issues arise. Unfortunately, the lack of responsiveness has made it difficult to trust this plugin for long-term use.



I hope the team improves their support response time in the future.
