Understand event tracking to optimize your marketing channels. Learn how to leverage this technique for channel success.

Understanding user interactions is vital for businesses aiming to enhance user experiences and business results. By tracking events, companies can comprehend what their users are doing on their mobile applications, websites and landing pages etc. This valuable data allows them to optimize their services to better cater to their customers. This is a crucial part of user behavior analysis using web analytics tools, contributing to user engagement and ultimately improving the conversion rate.

This article covers the fundamentals of event tracking and its applications. You will learn the definition of event tracking, how it works, the common types of events collected, different use cases, as well as tools that can be utilized for implementation.

What is Event Tracking?

Event tracking essentially operates as a mechanism that allows you to monitor and collect data about how visitors interact with your web pages and mobile applications. It goes beyond simply tracking page views to capture specific events like user clicks, form submissions, ecommerce purchases, or other custom events carried out by users. Each event recorded creates a timestamped trail of user journeys, stitching together sequences from initial access to goal completion.

The continuous collection of these event data enables deeper behavioral analysis. By connecting the dots of individual events, we can discover usage patterns to optimize user funnels, uncover breakdowns in key workflows, customize user experiences, and ultimately craft targeted enhancements to reduce bounce rates, and improve engagement and conversion rates.

Inner workings of Event Tracking

Here's how event tracking typically works:

  1. Event definition:
    1. Identify the specific user actions you want to track. These could be common actions like button clicks, form submissions, a certain popup appearing, and video plays, or custom events specific to your website or app functionality.
    2. Define the event category, action, and label for each event. This helps organize your event data and make it easier to analyze.
  2. Code implementation:
    1. Embed event tracking code (usually provided by your analytics platform) into your website or app code following standard naming conventions for event names. These code snippets trigger an event hit whenever the configured event action occurs.
    2. For websites, you can use JavaScript libraries like Google Tag Manager (GTM) to create new tags or manage existing event tags. For mobile apps, you can use platform-specific SDKs provided by your analytics platform.
  3. Event data transmission:
    1. When an event occurs, the tracking code sends an event hit to your analytics platform. This hit includes the event name, event category, event action, label, timestamp, and any associated user data.
    2. Your analytics platform then processes this data and makes it available for analysis in reports and dashboards.
  4. Analysis and insights:
    1. Use the event data collected through event tracking to gain insights into user behavior. You can analyze how often users are performing certain actions, which pages or features they are interacting with most, and how various marketing campaigns are performing.
    2. These insights can inform your website or app development, marketing strategy, and overall business decisions.

For example, the below event payload can represent a user purchase action on an ecommerce website:

"event_name": "purchase",
"event_category": "Transaction",
"event_action": "Complete",
"order_id": "123456",
"order_total": 100.0,
"order_items": [
"product_id": "12345",
"product_name": "Eco-Friendly T-Shirt",
"product_quantity": 2,
"product_price": 35.0
"product_id": "54321",
"product_name": "Sustainable Hat",
"product_quantity": 1,
"product_price": 25.0
"user_id": "abc123"

When this information streams into the analytics system, it unlocks rich insights around shopping behavior - from individual product performance to sales funnel optimization.

Different Categories of Events

The possibilities to use event tracking span far and wide, but avoiding data overload is key. Before instrumenting code across every interaction, strategize with internal teams to identify and prioritize opportunity areas aligned to core business goals. This focused approach ensures the event data captured fuels targeted analysis around moving key metrics. While use cases differ across organizations, some commonly tracked categories include:

  • Leads: Tracks user actions indicating interest in your product or service, such as submitting a contact form or downloading a whitepaper.
  • Sign-ups: Tracks user registrations for your service or account creation, reflecting initial commitment.
  • Purchases: Tracks successful completion of orders and transactions, signifying the ultimate conversion goal.
  • Adds to Cart: Tracks users adding items to their cart, indicating intent to purchase but not final commitment.
  • Checkout Steps: Tracks progress through the checkout process, offering insight into potential drop-off points.

Business Metrics Events

Tracking business performance events reveals how website or application activity links to bottom line results. Some examples of business metrics events are:

  • Revenue: Logs monetary intake from purchases, subscriptions, donations, etc to gauge income generation
  • Average Order Value: Calculates dollar amount per individual transaction to understand purchasing behavior
  • Lead Quality Score: Rates incoming leads on attributes like source campaign to prioritize follow-ups
  • Content Consumption: Tallies downloads, reads, views per asset to quantify content marketing traction
  • Registration Completion Rate: Measures percentage of sign-up flows finished to identify and fix drop-off points

Technical Performance Events

Technical performance events reflect the effectiveness and efficiency of your website or application's underlying infrastructure and functionality. Some of the performance tracking events are listed below

  • Page Load Times: Track the time it takes for pages to load.
  • Error Occurrences: Track errors that occur on your website.
  • JavaScript Errors: Track JavaScript errors that occur on your website.
  • Network Activity: Track network requests and responses.

Apart from these you can track many other types of events based on your use cases.

Different Use Cases of Event Tracking

While event tracking is fundamentally about monitoring user interactions, its marketing applications stretch much further. The technique now ties website behaviors to downstream efforts like multi-channel attribution, personalized messaging, and experience optimization. Event data enables continual refinement of not just technology but also creative marketing strategy based on how visitors actually engage over time.

Marketing and Advertising

Event tracking allows businesses to measure the effectiveness of their marketing campaigns and optimize ad targeting. By analyzing clicks, conversions, and social media engagement, businesses can identify which campaigns are generating the most results and tailor their targeting to reach the most interested audiences. Additionally, event data can be used to personalize marketing communications and deliver relevant content to individual users based on their past behavior and preferences.

Website/App Optimization

Event tracking helps identify popular content, optimize website or application flow, and troubleshoot user experience issues. By tracking page views, time on page, and scroll depth, businesses can understand which content resonates best with users and identify areas for improvement in website/app navigation or functionality. Additionally, tracking error occurrences provides valuable insights into technical problems impacting user experience.

Product Development

Event tracking helps businesses understand user needs, prioritize feature development, and measure product adoption. By analyzing in-app feature usage and user feedback, businesses can identify areas for product improvement and focus resources on developing features that are most used and valued by users. Additionally, tracking user sign-ups, usage patterns, and engagement levels helps businesses assess the overall success of their product.

Content Management

Event tracking provides valuable insights for content creators to publish content that resonates with their audience and optimize content distribution. By analyzing content engagement metrics such as page views, social shares, and comments, content creators can understand what types of content users find most valuable. Additionally, event data can be used to identify the best channels and timing for publishing content to reach target audiences and personalize content recommendations based on individual user interests and past behavior.

Attribute Conversions

Event tracking allows marketers to stitch together the complete path customers take from initial touchpoint to ultimate conversion. By logging key interactions with campaign tags and UTM parameters along the way, analysts can retrace each step of the journey. This can include which social media, SEO content, referral, or PPC ad introduced them, the landing pages they hit, site content consumed, emails received, all culminating with the final purchase or registration event. Mapping this sequence visualizes the influence over time of marketing efforts working in tandem to drive conversions. These insights then feed attribution models to quantify each touchpoint's proportional credit for driving the result, beyond just last-click wins all. This fills attribution reporting with truth around synergies between channels over the full time horizons that modern buyers travel. The end result is budget and resource allocation aligned to multi-faceted marketing strategies tuned to user reality, rather than assumptions.

Beyond these specific use cases, event tracking also plays a crucial role in compliance and security, fraud detection and prevention, and research and analytics.
