In ecommerce, true success is determined by converting website visitors into customers or engaged subscribers—not just driving traffic. To achieve this, you must focus on optimizing every stage of the customer journey and use conversion tracking to identify and improve what works best for your business.
This reshapes the whole strategy of attracting prospective customers. You don’t want to get just any people to come to your site, you want people with the highest chances of converting. That requires tuning your ads, landing pages and above all, tracking conversions.
What Is a Conversion in Ecommerce?
In the context of ecommerce, a conversion refers to a desired action taken by a visitor on your website that aligns with your business goals. It could be making a purchase, signing up for a newsletter, filling out a form, or any other action that indicates a successful engagement with your brand.
A conversion should be:
- Measurable. This excludes any brand awareness campaigns. It should be easy to tell when and if a conversion has occurred.
- Specific. A conversion should be tied to a sinngle event. You should be able to differentiate between various conversion types.
- Individual. A conversion is always preceded by other events, such as a click on an ad and a visit on a page. You should be able to attribute a conversion to an original event that has started the conversion flow.
What Types of Conversions Should Ecommerce Marketers Track?
Conversions can vary depending on the objectives of your ecommerce business. Some common types of conversions include:

- Purchase or transactional conversions
- Lead generation conversions
- Email sign-ups
- Account registrations
- Add-to-cart actions
Remember that each conversion may carry some additional data. Purchase conversions should also pass information about order value. Additionally, consider if your tracking setup allows you to register upsells – that is, subsequent conversions. This situation occurs when a single user makes two transactions. Usually, this means that a user will have a single identifier (usually called a click ID) assigned to them but they will have unique transaction IDs assigned to each purchase.
