=== GTM4WP - A Google Tag Manager (GTM) plugin for WordPress === Contributors: duracelltomi Donate link: https://gtm4wp.com/ Tags: google tag manager, tag manager, gtm, google ads, google analytics Requires at least: 3.4.0 Requires PHP: 7.4 Tested up to: 6.8 Stable tag: 1.22.1 License: GPLv3 License URI: http://www.gnu.org/licenses/gpl.html Advanced tag management for WordPress with Google Tag Manager == Description == 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](https://marketingplatform.google.com/about/tag-manager/). 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](https://developers.google.com/tag-platform/tag-manager/datalayer#datalayer). **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) = 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. = 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](https://developers.google.com/tag-manager/ecommerce-ga4) * 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](https://developers.google.com/tag-manager/serverside/send-data#update_the_gtmjs_source_domain) 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. == Installation == 1. Upload `duracelltomi-google-tag-manager-for-wordpress` to the `/wp-content/plugins/` directory 1. Activate the plugin through the 'Plugins' menu in WordPress 1. Go to Settings / Google Tag Manager and enter your Google Tag Manager container ID and set additional options == Frequently Asked Questions == = 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. == Screenshots == 1.
