Plugin: duracelltomi-google-tag-manager (Used by 89,300 domains)

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 it 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.

PHP 7.4 is required to use this plugin.

GTM container code placement

The original GTM container code is divided into two parts:

The first part is a javascript code snippet that is added to the 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.

The second part is an iframe snippet that acts as a failsafe/fallback should users’ JavaScript be disabled.
Google recommends – for best performance – to place this code snippet directly after the opening 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, set the compatibility mode in plugin options to off.

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
add the code lower in the code (it is not the recommended way but will work)

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/

Weather data

(beta)

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

(experimental)

Track users’ interaction with any embedded media:

• YouTube
• Vimeo
• Soundcloud

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.

Scroll tracking

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

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
and/or custom JavaScript variables you can secure the Tag Manager container.

Integration

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)
• WooCommerce:
  • Implementation of GA4 E-commerce
  • Does not support promotions since WooCommerce does not have such a feature (yet)
  • Does not support refunds
  • Compatibility with High Performance Order Storage (HPOS)
• AMP: load your AMP container on the AMP version of your pages
• Cookiebot: use automatic cookie blocking mode if needed
• Google Consent Mode v2: fire the “default” command with specific consent flags to integrat with non-certified Consent Management Platforms (CMPs) and plugins.

Server side containers

If you are using a server side container
you can enter your custom domain name and custom path to load gtm.js from your there.

Exclude specific user roles from being tracked

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.
