What is Core Web Vitals?
From the official page (https://web.dev/vitals/) Web Vitals is:
[…] an initiative by Google to provide […] quality signals that are essential to delivering a great user experience on the web.
[…]
Core Web Vitals are the subset of Web Vitals that apply to all web pages, should be measured by all site owners, and will be surfaced across all Google tools.
Each of the Core Web Vitals represents a distinct facet of the user experience, is measurable in the field, and reflects the real-world experience of a critical user-centric outcome.
Why are them important?
They are important not only to improve user experience on websites but also because since 2021 Core Web Vitals will become official ranking signals for Google (https://webmasters.googleblog.com/2020/05/evaluating-page-experience.html).
HOW TO track into Google Tag Manager
This plugin adds following data to the dataLayer object:
dataLayer.push({
event: “web-vitals”,
event_category: “Web Vitals”,
event_action: ,
event_value: ,
event_label: ,
});
You only need to create a custom event trigger in your Google Tag Manager (see https://support.google.com/tagmanager/answer/7679219?hl=en#), create Data Layer Variables and track those as Google Analytics Events on Tag Manager.
HOW TO track into third party tools or custom Google Tag Manager syntax
This plugins allows developers to listen for data captured and track them as their prefer. You only need to create a global Javascript function named
window.wpWebVitalTrack
and you’re done!
E.g.:
window.wpWebVitalTrack = function(event_id, event_name, event_value, event_delta) {
console.log(“Ready to do something amazing!”, event_id, event_name, event_value, event_delta);
// do something amazing!
}
NOTE: create this method as early as possible to avoid missing some event!
