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
using an intuitive web UI. To learn more about this tool, visit the official website.
This plugin places the GTM container code snippets onto your wordpress website so that you do not need to add this manually.
Multiple containers are also supported!
The plugin complements your GTM setup by pushing page meta data and user information into the so called data layer.
Google’s official help pages includes more details about the data layer.
You can also add your Google Optimize container with the recommended code setup
PHP 7.4 is required to use this plugin.
GTM container code placement
The original GTM container code is divided into two parts:
<head> section of every page of the website.
This part is critical to enable all features of GTM, and this plugin helps to place this part
correctly on your site.
Google recommends – for best performance – to place this code snippet directly after the opening
<body> tag on each page.
Albeit not ideal, it will work when placed lower in the code. This plugin provides a code placement option for the second code snippet.
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.
Users of the Genisis theme, GeneratePress theme, Elementor, Oxygen Builder and Beaver Builder Theme will also have this placed correctly.
To utilize this, use the “Codeless” placement option.
All other users can place this second code snippet using a custom PHP code (“Custom” placement option) or select the so called “Footer” option to
add the code lower in the code (it is not the recommended way but will work)
Basic data included
- post/page titles
- post/page dates
- post/page category names
- post/page tag names
- post/page author ID and name
- post/page ID
- post types
- post count on the current page + in the current category/tag/taxonomy
- custom terms associated with any post type
- logged in status
- logged in user role
- logged in user ID (to track cross device behaviour in Google Analytics)
- logged in user email address (to comply with GTM terms of service do not pass this on to Google tags)
- logger in user creation date
- site search data
- site name and id (for WordPress multisite instances)
- IP address of the visitor (please use the explicit consent of the visitor to utilize this)
Browser / OS / Device data
- browser data (name, version, engine)
- OS data (name, version)
- device data (type, manufacturer, model)
Data is provided using the WhichBrowser library: http://whichbrowser.net/
Push data about users’ current weather conditions into the dataLayer. This can be used to generate weather-related
audience/remarketing lists on ad platforms and allows for user segmentation in your web analytics solutions:
- weather category (clouds, rain, snow, etc.)
- weather description: more detailed data
- temperature in Celsius or Fahrenheit
- air pressure
- wind speed and degrees
Weather data is queried from Open Weather Map. Depending on your websites traffic, additional fees may apply:
An (free) API key from OpenWeatherMap is required for this feature to work.
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:
Media player events
Track users’ interaction with any embedded media:
DataLayer events can be chosen to fire upon media player load, media is being played, paused/stopped and optionally when
the user reaches 10, 20, 30, …, 90, 100% of the media duration.
Tracking is supported for embedded media using the built-in oEmbed feature of WordPress as well as most other media plugins
and copy/pasted codes. Players injected into the website after page load are not currently supported.
Fire tags based on how the visitor scrolls from the top to the bottom of a page.
An example would be to separate “readers” (who spend a specified amount of time on a page) from “scrollers”
(who only scroll through within seconds). You can use these events to fire Analytics tags and/or remarketing/conversion tags
(for micro conversions).
Scroll tracking is based on the solution originally created by
- Nick Mihailovski
- Thomas Baekdal
- Avinash Kaushik
- Joost de Valk
- Eivind Savio
- Justin Cutroni
Google Ads remarketing
Google Tag Manager for WordPress can add each dataLayer variable as a Google Ads remarketing custom parameter list.
This enables you to build sophisticated remarketing lists.
Blacklist & Whitelist Tag Manager tags, triggers and variables
To increase website security, you have the option to white- and blacklist tags/triggers/variables.
You can prevent specific tags from firing or the use of certain variable types regardless of your GTM setup.
If the Google account associated with your GTM account is being hacked, an attacker could easily
execute malware on your website without accessing its code on your hosting server. By blacklisting custom HTML tags
Google Tag Manager for WordPress integrates with several popular plugins. More integration to come!
- 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)
- Classic e-commerce (deprecated):
- fire an event when visitors add products to their cart
- capture transaction data to be passed to your ad platforms and/or Analytics
- capture necessary remarketing parameters for Google Ads Dynamic Remarketing
- Enhanced e-commerce:
- Compatibility with High Performance Order Storage (HPOS)
- Classic e-commerce (deprecated):
- Google Optimize: load your Google Optimize container directly from your website with the ability to use the data layer variables provided during page load
- AMP: load your AMP container on the AMP version of your pages
Server side containers
If you are using a server side container
you can enter your custom domain name to load gtm.js from your there.
- Activate the plugin through the ‘Plugins’ menu in WordPress
- Go to Settings / Google Tag Manager and enter your Google Tag Manager container ID and set additional options
ہرہک دے سوال
How can I …
Tutorials for various Google Tag Manager settings and implementation are available on my website:
PayPal / 3rd party payment gateway transactions in WooCommerce are not being tracked in Google Analytics
PayPal and some other 3rd party payment gateways do not redirect users back to your website upon successful transaction by default.
It offers the route back for your customer but it can happen that users close the browser before arriving at your thankyou page
(aka. order received page). This means that neither Google Analytics tags or any other tags have the chance to fire.
Enable auto-return in your payment gateway settings. This will instruct them to show a quick info page after payment
and redirect the user back to your site. This will improve the accuracy and frequency of tracked transactions.
Why isn’t there an option to blacklist tag/variable classes
Although Google recommends to blacklist tags and variables using classes, people struggle to know
which tags/variables gets affected. Therefore I opted for individual tags and variables rather than classes
on the blacklist tabs.
Regarding variables; ensure they are not part of any critical tags as blacklisting such variables will render said tags useless.
How can I track scroll events in Google Tag Manager?
Google Tag Manager supports basic scroll depth tracking based on percentage or pixels natively. This plugin adds
additional scroll tracking events, more focused on capturing the users’ intent and/or engagement.
There are five dataLayer events you can use in your rule definitions:
- gtm4wp.reading.articleLoaded: the content has been loaded
- gtm4wp.reading.startReading: the visitor started to scroll. The
timeToScrolldataLayer variable stores duration since the article loaded (in seconds)
- gtm4wp.reading.contentBottom: the visitor reached the end of the content (not the page!).
timeToScrolldataLayer variable updated
- gtm4wp.reading.pagebottom: the visitor reached the end of the page.
timeToScrolldataLayer variable updated
- gtm4wp.reading.readerType: based on time spent since article loaded we determine whether the user is a ‘scanner’ or ‘reader’ and store this in the
Example use cases: using these events as triggers, you can fire Google Universal Analytics and/or Google Ads remarketing/conversion tags
to report micro conversions and/or to serve ads only to visitors who spend more time reading your content.
Can I exclude certain user roles from being tracked?
This is easily managed through GTM itself. If you want to exclude logged in users or users with certain user roles,
use the corresponding dataLayer variable (visitorType) and an exclude filter in Google Tag Manager.

- Fixed: GTM ID not properly set in noscript tag (probably fixes some 403 errors with firewalls too)
This plugin version does not add or update any functionality.
After recent events, the code of the plugin has been checked line by line to see where additional security checks can be added.
The code has been formatted to better support readability for other programmers.
* gtm4wp_get_the_gtm_tag hook and the corresponding GTM4WP_WPFILTER_GETTHEGTMTAG PHP constant.
* gtm4wp_add_global_vars hook and the corresponding GTM4WP_WPFILTER_ADDGLOBALVARS PHP constant. Use gtm4wp_add_global_vars_array / GTM4WP_WPFILTER_ADDGLOBALVARS_ARRAY instead.
* gtm4wp_after_datalayer hook and the corresponding GTM4WP_WPACTION_AFTER_DATALAYER PHP constant. Use gtm4wp_output_after_datalayer / GTM4WP_WPACTION_AFTER_DATALAYER instead witch can be used in the same way but it is an action instead of a filter.
Upcoming version will come with important changes:
* Minimum PHP version will be raised to 7.4: this will allow me to add even more safety measures
* Minimum supported WooCommerce version will be raised to WooCommerce 5.0: with this I can remove some very old compatibility code
* Deprecated features will be removed (aims to simplify code for better maintenance):
* Do not track flag of the browser added into data layer
* Legacy version of WooCommerce dynamic remarketing (using ecomm_ parameters)
The goal of all these changes aim to keep the plugin code clean and free from legacy solutions.
- Deprecated option: ‘do not track’ flag of the browser. This browser feature itself is now deprecated
Full scan of the plugin is also in works to fix any other possible XSS issue.
- Fixed: possible XSS Vulnerability if Cloudflare country code option enabled. Thanks Guillaume Fortier
