What Is a Conversion and What Counts as One?

A conversion is recorded when a visitor completes one of the conversion actions you’ve defined for a test.

Conversions are the primary way Nelio A/B Testing measures how successful each variant is at achieving your optimization goals.

For example, a conversion might be:

• clicking a call-to-action button;
• submitting a contact form;
• adding a product to the cart;
• completing a purchase; or
• visiting a specific page.

What counts as a conversion depends entirely on the conversion actions you’ve configured for your test.

How Are Conversions Counted?

A conversion is only recorded after a visitor has participated in the test.

The process is straightforward:

1. A visitor views a page that’s part of the test.
2. Nelio A/B Testing assigns the visitor to a variant.
3. The visitor performs one of the configured conversion actions.
4. Nelio records a conversion for that variant.

This ensures conversions are always associated with the version of the page the visitor actually experienced.

Can the Same Visitor Convert More Than Once?

Yes.

Unlike some analytics platforms, Nelio A/B Testing allows the same visitor to trigger the same conversion goal multiple times.

For example, a visitor might:

• make multiple purchases;
• submit several forms; or
• repeatedly perform another tracked action.

Because of this, a conversion rate can sometimes exceed 100%.

How Is the Conversion Rate Calculated?

For each variant, Nelio A/B Testing calculates the conversion rate as:

Conversion Rate = Conversions ÷ Tested Page Views

A higher conversion rate generally indicates a better-performing variant.

Nelio also calculates the statistical confidence of the results to help you determine when there’s enough evidence to declare a winner.

Why Aren’t My Conversions Being Recorded?

If your test isn’t recording conversions, check that:

• the visitor has viewed the tested page before performing the conversion;
• the conversion action is configured correctly;
• the visitor isn’t excluded by segmentation or tracking settings; and
• tracking isn’t blocked by consent or another configuration.

If everything appears to be configured correctly, use the Debug Tools to verify that conversion events are being detected.

If your test isn’t recording conversions yet, you may want to check: Why do I still have no results of my test?
