Conversion
Also known as: conversion event, goal completion
What Is Conversion?
A conversion is a specific action a user takes that aligns with a product or business goal. Signing up for a free trial, submitting a contact form, completing a purchase, activating a feature for the first time: each one counts as a conversion, provided the team defined it as a target beforehand.
The term gets used loosely, so the definition depends entirely on context. What converts a user on a B2B SaaS product looks very different from what counts on an e-commerce site.
How Is the Conversion Rate Calculated?
Conversion rate = (Number of conversions ÷ Total visitors) × 100
If 1,200 people landed on a pricing page and 84 clicked "Start free trial," the conversion rate is 7%. Simple math.
The harder part is deciding which actions to count and over what time window. Tracking too many conversions at once makes it difficult to tell which design changes are driving movement.
What Are Macro and Micro Conversions?
Not all conversions carry equal weight. Teams usually split them into two categories.
Macro conversions are the primary goals: a completed purchase, a signed contract, and a submitted demo request. These tie directly to revenue and sit at the bottom of the funnel.
Micro conversions are the smaller steps that lead there: watching a product video, adding an item to a cart, returning to the product three days in a row. They don't generate revenue on their own, but they predict a macro conversion is coming. Tracking them helps teams spot where users lose momentum before reaching the final step.
What Are the Pros and Cons of Using Conversion as a Metric?
Pros
Concrete and measurable: unlike engagement metrics, conversion ties directly to a defined outcome.
Tracks design impact over time: a rising conversion rate is one of the clearest signals that a UX change worked.
Provides shared language between design and business teams, making it easier to justify design investment.
Cons
Tells you something is wrong, not what: a falling rate points to a problem without naming it.
Non-UX factors affect it, including ad quality, seasonality, and pricing changes, which can distort what looks like a design issue.
Optimizing too narrowly for conversion can push teams toward design decisions that pressure users.
What Does a Declining Conversion Rate Signal?
Steady traffic with falling conversions usually points to friction somewhere in the product. Users are arriving but not completing what they came to do. The gap between arrival and action is where the problem lives.
A UX audit is one of the more reliable ways to locate it. Audits evaluate the product systematically across navigation, onboarding, and task completion, surfacing prioritized findings tied to business impact rather than surface-level guesses about what went wrong.
