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

Descrizione

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 <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.

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 <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, 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)

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 format
  • 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 (both unhashed and SHA256 hased values to be used with tracking)
  • 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/

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:
http://openweathermap.org/price

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:
https://ipstack.com/product

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

Original script:
http://cutroni.com/blog/2012/02/21/advanced-content-tracking-with-google-analytics-part-1/

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.

Integrazione

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.

FAQ

How can I …

Tutorials for various Google Tag Manager settings and implementation are available on the plugin’s website:
https://gtm4wp.com/setup-gtm4wp-features

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.

Purchase event is not tracked with WooCommerce

If you are using a 3rd party plugin that alters the default order received page in a way that does not utilize the integration hooks
of WooCommerce then this can happen. Either stop using this 3rd party plugin or ask them to better mimic the behavior of the
default order received page by supporting the woocommerce is_order_received_page and the woocommerce_thankyou actions and filters.

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 timeToScroll dataLayer variable stores duration since the article loaded (in seconds)
  • gtm4wp.reading.contentBottom: the visitor reached the end of the content (not the page!). timeToScroll dataLayer variable updated
  • gtm4wp.reading.pagebottom: the visitor reached the end of the page. timeToScroll dataLayer 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 readerType dataLayer variable

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.

Recensioni

20 Ottobre 2024
I was stuck for hours trying to tweak the litespeed cache plugin so it’d work with Google Tag Manager. The solution was simple: use gtm4wp. For some reason, this plugin avoids the conflicts with litespeed cache (allowing your tags to fire). I’m so happy this works because my site really needs the performance boost from litespeed while being able to track results. A huge thank you to the developper!

Support is nonexistent, enabling tracking post pages will break your site if it’s not a post not woocommerce page. Excluding administrator from tracking doesn’t work neither.
26 Marzo 2024
Since the “official” Google Analytics plugin for WooCommerce was broken by the developers and has been for weeks now I had to start looking for alternatives. I’ve used GTM4WP before as well and to be honest I’m not sure why I ever switched. Switching back to GTM4WP I can finally get conversions recorded again in my GA4! This is amazing! Why is this plugin even free? Would easily pay for it
21 Marzo 2024
The latest update broke tracking for myself and a lot of other people with no real response from developer. It also trashed my Analytics with some products showing numbers like this for added to cart: 100,000,000,000,001No longer recommended.

THE BIG CLEANUP RELEASE!

Lots of deprecated features removed.
The code of WooCommerce integration was cleaned and restructured, if you have any custom code that relies on GTM4WP internal data structure,
please update the plugin on a test version of your website before updating your live site!

  • Removed: deprecated Universal Analytics events for WooCommerce
  • Removed: deprecated filter GTM4WP_WPFILTER_AFTER_DATALAYER/gtm4wp_after_datalayer
  • Removed: deprecated filter GTM4WP_WPFILTER_ADDGLOBALVARS/gtm4wp_add_global_vars
  • Removed: deprecated feature that puts the ‘Do not track’ option of the browser into the data layer. It is a deprecated browser feature therefore removed from this plugin.
  • Removed: deprecated Google Optimize integration
  • Removed: deprecated constants GTM4WP_OPTION_BLACKLIST_MACRO_* and GTM4WP_OPTION_BLACKLIST_
  • Removed: deprecated WordPress filter GTM4WP_WPFILTER_GETTHEGTMTAG (deprecated in v1.16)
  • Changed: lots of internal function names and variable names changed, although is not recommended to depend on them, if you did, check your code
  • Changed: renamed WP filter gtm4wp_datalayer_on_pageload to gtm4wp_woocommerce_datalayer_on_pageload to better reflect when it is called.
  • Changed: orderData data layer variable in WooCommerce integration now includes keys to better support enhanced conversions setup:
    • orderData.customer.billing.first_name_hash
    • orderData.customer.billing.last_name_hash
    • orderData.customer.billing.phone_hash
  • Deprecated: orderData.customer.billing.emailhash, please update to use orderData.customer.billing.email_hash (with an underscore)
  • Added: stockstatus key into the product array of every ecommerce action. Returns the value of WP_Product->get_stock_status(). Thanks hans2103.
  • Added: integration with WebToffee GDPR Cookie Consent plugin. GTM4WP can not fire a GTM event when user consent changes or when a previously stored consent has been loaded.
  • Fixed: add_payment_info and add_shipping_info events were not fired during checkout submit when not fired before on the page.
  • Fixed: GTM4WP will only look for the user’s IP address in the REMOTE_ADDR server variable. You may enter a custom HTTP header instead in plugin settings.

1.19.1

  • Fixed: run additional checks when determing product category to prevent PHP errors in certain cases
  • Fixed: corrected Consent Mode flag names in admin page description texts

1.19

WARNING!
Universal Analytics / GA3 ecommerce events deprecated!
Please update your GTM setup so that it does not rely on any of the following GTM4WP events and the old ecommerce data layer:
* gtm4wp.productClickEEC
* gtm4wp.addProductToCartEEC
* gtm4wp.removeFromCartEEC
* gtm4wp.checkoutOptionEEC
* gtm4wp.checkoutStepEEC
* gtm4wp.changeDetailViewEEC
* gtm4wp.orderCompletedEEC

Instead of the above events, you can use the new GA4 ecommerce events (add_to_cart, purchase, etc.)
In the Universal Analytics GTM tag now you have an option to use the GA4 ecommerce data in the data layer.
If you are on GA360 and still collecting ecommerce data, you need to update your GTM setup to use that option firing on the GA4 ecommerce events.

  • Updated: WooCommerce integration now accepts the primary category selection of Yoast SEO and Rank Math SEO
  • Updated: use the gtm4wp_admin_page_capability filter to modify the capability needed to use the admin page (thanks emreerkan)
  • Fixed: price did not include the .00 postfix for integers in the add_to_cart event
  • Added: if needed, you can turn on clearing the ecommerce object before a new GA4 event is being pushed.
  • Added: support for Google Consent Mode default command for use cases where the consent management tool does not support it already

  • Added: Create a cookie named block_gtm4wp_geoip after a specific user selected cookie preferences. Set the value to either “yes”, “true”, “on” or “1” and the GeoIP (and weather API) feature will be disabled for that particular user

1.17

  • Added: pagePostTerms data layer variable will now also include a meta key with post meta values that does not start with the _ character. This should allow to utilize custom fields added by plugins like Advanced Custom Fields.
  • Added: new filter: gtm4wp_post_meta_in_datalayer to limit which post meta should be present with with the previously added feature.
  • Added: ability to use a custom path for your server side GTM container. This makes GTM4WP compatible with services like stape.io

  • Fixed: JavaScript error in Chrome around event.target.closest calls, thanks pinkasey for the fix
  • Fixed: cast _ga_tracked variable as integer to make the identical operator work correctly, thanks Irfan for the suggestion
  • Fixed: removed extra code added in 1.14 that reloads pages in Safari in WooCommerce integration. It broke some sites.
  • Updated: required PHP version raised to 7.4. Currently, this is not a hard requirement but from now I could include updates that will require this PHP version.

1.16.1

  • Fixed: GTM ID not properly set in noscript tag (probably fixes some 403 errors with firewalls too)

1.16

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.

Deprecated:
* 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.

1.15.2

  • Fixed: Stored XSS when using the scroll tracking feature and an admin changes the content element ID into a JavaScript code.
  • 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.

1.15.1

  • Fixed: JavaScript error with the newly added console logging to debug code placement issues
  • Fixed: possible XSS Vulnerability if Cloudflare country code option enabled. Thanks Guillaume Fortier
  • Fixed: proven XSS Vulnerability if adding site search into the data layer was enabled. Original report by not_stoppable. Root cause analysis by Cory Buecker.
  • Removed: deprecated feature Google Ads remarketing. This is the outdated, classic way using the google_tag_params variable.
  • Dev: removed PHP constant GTM4WP_WPFILTER_COMPILE_REMARKTING (related to removed Google Ads remarketing feature)
  • Dev: removed gtm4wp_compile_remarkering WordPress filter (related to removed Google Ads remarketing feature)

Note to plugin users: I sincerely appologize for the vulnerabilities. To make sure, such cases do not happen again,
the next version will be fully dedicacted to go through every peace of code and make sure proper data processing is happening in GTM4WP.
