What is Conversion Rate?

Turkish: Dönüşüm Oranı

Conversion rate measures the percentage of visitors who complete a target action such as buying, signing up, or submitting a form.

What is Conversion Rate?

Conversion rate is the share of visitors or sessions that complete a defined goal. The goal might be a purchase in e-commerce, a quote form on a B2B site, a trial signup in SaaS, or a newsletter subscription.

How Is It Calculated?

The basic formula is: conversion rate = conversions / visitors x 100. If 5,000 sessions produce 150 quote requests, the conversion rate is 3 percent. The measurement rules should be defined first: whether the denominator is users or sessions, whether repeat conversions count, and whether bot traffic is excluded.

Types of Conversion

  • Macro conversion: The main business goal, such as purchase, payment, or lead submission
  • Micro conversion: An intermediate signal, such as add to cart, demo page view, or newsletter signup
  • Channel conversion: Rates segmented by organic search, ads, email, or social traffic

Relationship with CTR

CTR measures how often people click a result or ad; conversion rate measures whether the intended goal happens after the click. High CTR with a low conversion rate may indicate that the message and landing page do not match user expectations.

Business Use

Conversion rate optimization looks at form length, pricing presentation, trust signals, page speed, and mobile usability together. Changes should be evaluated with measurement rather than instinct, ideally using A/B testing and a sample size large enough to trust.
