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.

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.

Tip: Maintaining Proper Session Attribution in GA when using OAuth providers with Google Tag Manager

If you using Facebook, Twitter, Github or any other service to autenticate your users, you may have noticed that they end showing up as referral traffic from the oauth service.

User lands from CPC -> Logs in -> Respawns a new visit as referral

We could think on adding those domains to the ignored referrals within our view configuration, but this will and hidding the real referal traffic from those networks.

Tip: Grabbing the visitor’s first date from cookies using Google Tag Manager


With the new Universal Analytics cookies and everything being calculated server-side, it’s more difficult to detect some attribution problems or verifying if they were already fixed.

For example after fixing a self-referrals problem we can continue getting more of them in our reports if some users were previusly tagged in Google Analytics.
