Event tracking is a very important part of analytics tracking. We cannot get deeper insights only with page view metrics. The aim here is to understand the behavior of visitors within the site. So, we need to identify the micro and macro conversions within the site and implement analytics tracking for all those interactions. For example, an ecommerce site’s macro conversion is “order conformation” and the micro conversions are steps towards the macro goal which is adding products to cart, clicking on check out etc. which have to be tracked.
To test this, out in your website, look for key CTAs which can be a micro goal or a macro conversion and click on that. Clicking it should trigger a Google Analytics “event” tag. As shown below, the event tag will have value “t=event”. This tag will have details about the interaction under ec, ea & el which is Event Category, Action and Label respectively.
If you don’t find any event tag on click of a key interaction, then it means that you have to implement the required code track it. Without it, you cannot derive useful insights from your analytics data.
