5 years ago, on 1st October 2012, this lovely video popped up in Google’s Analytics Blog: It was accompanied by a blog post, which contained a brief look into many of Google Tag Manager’s key features, some of which are still relevant today. Google Tag Manager is a free tool that consolidates your website tags with a single snippet of code and lets you manage everything from a web interface. You can add and update your own tags, with just a few clicks, whenever you want, without bugging the IT folks or rewriting site code.

Ever since the Lookup Table variable was introduced in Google Tag Manager, users have been craving for more. The Lookup Table does exactly what it promises: lookups. These are exact match operations, which are extremely inexpensive to perform, because they can only have a binary result: either the match exists in the data store being queried or it doesn’t. This performance stays constant even if the data store being queried increases in size.

Last updated 20 April 2020: Clarified how lazy-loaded videos can be tracked with this trigger. Let’s cut straight to the chase. Google Tag Manager has just released the YouTube Video trigger, which gives you native support for YouTube video tracking. And it’s great!

This is particularly the case when the selection immediately does something, such as initiate a download or navigate the user to another page. But even if there is no immediate action, it’s still interesting to know what selections users might be doing, if only to uncover yet another piece of the engagement puzzle. Here’s the Google Tag Manager way to do it!

Facebook’s pixel has an attribute named content_ids (required for Dynamic Ads), which requires an Array of content IDs as its value. It’s very possible you’re running this pixel on a site which already has Enhanced Ecommerce for Universal Analytics implemented, and now you want to use the same Enhanced Ecommerce data that your developers have already made available in this Facebook pixel. Or perhaps you want to concatenate a list of strings, such as article tags (['culture', 'politics']), and send it as a comma-separated string to Google Analytics ('culture,politics').
