It's one thing to get users to visit your website or try your app, and it's another to know exactly what they do on your platform. This is where event tracking comes into play. It is a revolutionary data analytics technique that provides detailed insights into how users interact with digital platforms. Read on to find answers to common questions about event tracking.

What Is Event Tracking?

Event tracking is an advanced analysis of the interactions users have on your website or mobile app. It goes beyond common metrics like page views to track specific and minute details and heat maps that can help you better understand user behaviors, user experience, and the overall performance of your platform. 

For instance, if you want to know how engaging your home page is, you could monitor how fast users scroll through the website and the farthest depth they take. Further, you could track how often they engage with the CTA, how much time they spend on each section of the page.

This may look like a lot, but when done properly and carefully, event tracking reports will help you increase user engagement, retention rate, and app conversions.

How Does Event Tracking Work?

To keep track of specific events or actions on your digital platform, you need to install some codes on the section of the platform you want to monitor user interaction events. JavaScript is the common programming language used for this purpose. However, you also need an event-tracking data analytical tool to implement the code.

Suppose you want to know how many times and how often the “Play” button on a demo video is hit. In that case, you'd install the code on the exact page where the video is, instructing it to count each time a user presses the button and the time interval between them. Here's an example of such a code:

<script>

  document.addEventListener("DOMContentLoaded", function () {

    let lastPlayTime = 0; // Stores the timestamp of the last play event

    // Select the video element by ID (Replace 'demoVideo' with your actual video ID)

    let video = document.getElementById("demoVideo");

    if (video) {

      video.addEventListener("play", function () {

        let currentTime = new Date().getTime(); // Get current timestamp

        let timeInterval = lastPlayTime ? (currentTime - lastPlayTime) / 1000 : 0; // Calculate interval in seconds

        // Update last play timestamp

        lastPlayTime = currentTime;

        // Send event to Reteno

        if (typeof reteno !== "undefined" && reteno.track) {

          reteno.track("video_play", {

            category: "Video",

            label: "Demo Video",

            time_interval: timeInterval, // Time since last play event

          });

        }

        console.log("Reteno: Video play event tracked. Time interval:", timeInterval, "seconds");

      });

    }

  });

</script>

We generated this code using the Reteno tracking platform. You can do something similar for any other event on your platform and get relevant insights for growing your business and customer engagement.

Types of Event Tracking Data

Reteno tracks two main types of event data: system-generated events and custom events.

System-Generated Events 

These events are automatically collected and include user interactions with omnichannel campaigns. Examples include:

  • Message delivery and its statistics (by device and domain): The system automatically tracks the successful delivery rate of messages (emails, SMS, push notifications) and divides them by device type (mobile, desktop) or domain (Gmail, Outlook, Yahoo).
  • Opens and clicks: It measures how many users open an email or notification and engage with embedded links. This helps provide insight into the effectiveness of an omnichannel customer journey.
  • Unsubscribes and spam complaints: When users opt out of a subscription plan or make reports about messages being spam, event tracking allows businesses to become aware of that.
  • Delivery errors: Here, failed message deliveries are tracked, along with the reasons, such as incorrect email addresses, spam filter rejections, and full inboxes.

Custom Events 

These are user-interaction events based on behavioral analytics of users within an app, website, CRM, or CMS interactions:

  • App and browser behavior: Engagement metrics such as pageview tracking, button clicks, and navigation flow within a website or mobile app are tracked and recorded.
  • Session duration: Session tracking is carried out to measure the amount of time users spend on an app or website. 
  • Orders: These include activities, such as order value, item, product category, and payment method. 
  • Subscription updates: It helps measure the user flow analysis, like new sign-ups and plan upgrades or cancellations, allowing businesses to assess their engagement metrics and implement improvements.
  • Custom outcomes: Here, businesses track their app user behavior through form submissions, video views, or successful transactions. These metrics are used to measure the app conversions and retention rates.

Event Tracking Best Practices

By following these event tracking best practices, businesses can optimize their analytics strategy and improve overall performance.

Define a Clear Tracking Plan

Before you think about implementing event tracking, it is important to understand and establish a very detailed and structured tracking plan. It should cover what part of your page or website would be tracked, the mode of tracking, and the event tracking tool to be used. A clear and well-defined tracking plan ensures that the collected data aligns with your business goals.

Standardize Event Naming Conventions

It involves designing a consistent pattern for naming events. Two common naming formats are snake_case and CamelCase.

In snake_case, all the letters are in lower case, and words are separated by “-” or “_” e.g., page-viewed and user_signup

In CamelCase, the first word is in lowercase or capitalized, and the first letter of the subsequent words is capitalized. Examples are PageViewed and UserSignup.

We recommend you use the CamelCase format

  • by capitalizing the first letter of each word — for event names (e.g., SubscriptionStarted),
  • by making the first letter of the first word lowercase and every subsequent word capitalized — for event params names (e.g., trialDuration).

Using a standardized and consistent naming style helps simplify data identification and analysis in a system.

Capture the Right Data

Instead of having a vague event-tracking system, you should focus on capturing only relevant data that aligns with your objectives. This would go a long way in further simplifying your organization’s data-driven decision-making. Some user interaction events that could be tracked include successful sign-ups, purchases, bounce rate, completed actions, and pageview.

Ensure Data Quality and Governance

Your data will only be relevant if it’s accurate and devoid of discrepancies. The presence of errors, inconsistencies, and missing details in your recorded event tracking data will lead to misleading insights and wrong decisions. So, it’s necessary to build a standard quality control system around your operations to ensure consistent and reliable data gathering. This will help your business make data-driven decision-making confidently.

Leverage User Identification

When users onboard your platform, they typically get a unique user ID (external ID for Reteno). This ID can be a source of digital trails when they interact with your platform. This way, you can record their behavioral analytics and use the information to offer personalized experiences.

Implement Event Properties and Context 

Event properties and context are additional information that makes the data obtained from event tracking more meaningful and insightful. Instead of generic data like timestamps, event names, and engagement metrics, you could drill it down to event-tracking properties like device type, location, referral source, and user roles. Collecting contextual information allows you to carry out user segmentation and personalization.

Integrate with Other Analytics Tools

Integrating your event-tracking tools with other analytic tools improves the success rate of your business events and behavior-tracking game. Analytic tools could include customer relationship management (CRM) and messaging automation tools like Reteno that could help increase your mobile app user retention rate.

Respect Privacy Regulations

Local and international laws frown against the indiscriminate gathering of customers' data. Most important laws in this domain are the California Consumer Privacy Act (CCPA) and Europe’s General Data Protection Regulation (GDPR). Before implementing any event tracking system for your company, ensure that the platform you’re using is fully compliant with the relevant laws and will not do anything to evade your users’ privacy.
