Hopefully you've read parts 1 and 2, where I talk about some of the useful browser extensions and tools that I use for debugging tags. This part is specifically about debugging Tealium iQ and tags deployed through it. I'll look at some tools and methods, and then we'll take a dive into the utag.js file itself.
Finding out why tags aren’t firing or why data aren’t being passed to Adobe Analytics or Google Analytics is one of the most frequent tasks we get asked to do by our clients. This post (and the follow ups) will go through some of the steps and techniques we use to identify, find and fix tagging problems.
