Debugging and monitoring GTM Variables for errors

Google Tag Manager does not throw any error when the code in a variable fails. This is not bad per se as it would save us from having our sites failing if something is not coded as it should, but it will blind us agains some minor errors that may not be noticiables, for example if our Enhanced Ecommerce is failing for a certain product, or from some specific browser.

Thanksfully we can use try{}catch(e){}Lee el resto de la entrada

Enabling Optimizely native Google Analytics Integration within Google Tag Manager

As you may already know, Optimizely has an in-built Google Analytics integration, which will allow us to track the experiments and variations being showed to a client using custom dimensions.

For enabling them, you’ll need to put the following lines after the create command and the pageview one:

window.optimizely = window.optimizely || [];
window.optimizely.push("activateUniversalAnalytics");

This is a bit tricky when using Google Tag Manager native tags, since it doesn’t allow you to execute anything after … Lee el resto de la entrada

To achive this we’ll be using a single Custom HTML tag ,a cookie and … Lee el resto de la entrada

Tracking the Hover Intent with Google Tag Manager

At the moment, Google Tag Manager listeners are limited to Form Submits, Link Clicks and Clicks (for any DOM element). We are going to write a custom listener for hover intents by users. This means that we’re not only to do something when the user pass the mouse pointer over an element, but instead we’re waiting a certain time with the mouse over the element before submitting the action to GTM.

For this we’re … Lee el resto de la entrada

Tips for debugging your Google Tag Manager implementations

I’m going to share some of the tips and tricks I’ve learnt (and that I use on my daily basics work) in the almost past 3 years since Google Tag Manager was released.

Tip #1 – Grabbing a dataLayer value from the console

If we want to grab the current value in the Google Tag Manager’s dataLayer, it offers a built-in get method for it. When GTM loads a global object is created named … Lee el resto de la entrada

Preventing duplicate transactions in Universal Analytics with Google Tag Manager

One of the most common headaches while implementing the ecommerce tracking on a site is trying to match the tracked transactions by the shop backend to Google Analytics. As most tracking solutions are JavaScript based, there’s a small chance of losing some of them and there’s nothing we can do without playing with the measurement protocol and some server-side tracking.

Another problem that is usually present is having duplicated transactions. And this hopefully is … Lee el resto de la entrada

Locating legacy hardcoded events and pageviews using Google Tag Manager

If you’re migrating from classic Google Analytics (_gaq object) to Universal Analytics, or planning to migrate your old hardcoded events to use Google Tag Manager you may have run in the case that not all old tracked was really removed from the site by the client. And it’s really hard to find it out.
