In digital marketing, an online conversion refers to a specific action taken by a website visitor, indicating that they have been “converted” from a passive visitor into an engaged user or customer.

To be effective, conversion opportunities need to be aligned with the website's business goals.

Examples of online conversions:

  • Making an online purchase
  • Filling out a contact form
  • Subscribing to a newsletter or email list
  • Creating an account or registering for a service
  • Downloading a white paper, e-book, or other resource
  • Clicking on a specific link or call-to-action button
  • Engaging with a chatbot or live chat service


Online conversions are tracked through various methods, including:

  • Conversion tracking pixels: Small pieces of code placed on a website that track specific actions and send data back to analytics platforms.
  • UTM parameters: Unique tracking codes added to URLs to identify the source, medium, and campaign that referred a user to the website.
  • Cookie-based tracking: Placing cookies on a user's browser to track their behavior across multiple visits and sessions.
    Server-side tracking: Tracking conversions directly on the website's server, which can be more accurate and less susceptible to ad blockers.
  • CRM integration: Connecting website data with customer relationship management (CRM) software to track conversions and user behavior across multiple channels.
  • By monitoring online conversions, businesses can measure the effectiveness of their digital marketing efforts, optimize their strategies, and allocate resources more efficiently to drive growth and revenue.
