conversion rate

conversion rate — The percentage of users or visitors who complete a desired action (such as making a purchase, signing up, or clicking a button) out of the total number of users who had the opportunity to do so.

In simple English

Conversion rate is a critical metric in business and product development that measures how effectively a product, website, or marketing campaign turns potential customers into actual ones. For example, if 100 people visit your website and 5 make a purchase, your conversion rate is 5%. This metric is used across many tech roles: product managers track it to understand user behavior, marketing teams optimize campaigns to improve it, and engineers build features to increase it. In tech companies, improving conversion rate by even 1% can mean significant revenue gains, making it a key focus area for teams. You will hear it discussed in product meetings, sprint planning, and performance reviews.

Understand what conversion rate means and how to calculate and improve it for websites, apps, and marketing campaigns.

Without saying 'rate,' it is unclear if you mean absolute numbers or the percentage. Always specify 'conversion rate' or 'number of conversions.'

Real examples(3)

  • in a standup

    "I finished the checkout flow redesign. Early testing shows a 15% improvement in conversion rate."

  • in a code review

    "This optimization should reduce page load time, which typically correlates with a higher conversion rate."

  • in a team meeting

    "Our conversion rate dropped after we changed the sign-up flow. We should revert and test more gradually."

More mistakes(2)

Handle with care. Do not confuse conversion rate with conversion itself. Conversion rate is the percentage or ratio, not the single event of a user converting.

  • ✕The conversion rate of users is very good.
    ✓Our conversion rate is very good.

    Conversion rate already refers to users. Saying 'conversion rate of users' is redundant.

  • ✕We should conversion rate this feature.
    ✓We should improve the conversion rate of this feature.

    Conversion rate is a noun, not a verb. You cannot 'conversion rate' something; you 'improve' or 'optimize' the conversion rate.

Questions(5)

What does conversion rate mean in tech?
Conversion rate is the percentage of users or visitors who complete a desired action. For example, on an e-commerce site, it is the percentage of visitors who make a purchase. In SaaS, it could be the percentage of free-trial users who become paying customers. It is calculated as (number of conversions / total number of visitors) × 100.
How do you use conversion rate in a work conversation?
You might say: 'Our conversion rate is 5%' (stating the current metric), 'We want to improve our conversion rate' (expressing a goal), or 'The conversion rate dropped after the redesign' (reporting a change). It is commonly discussed in product meetings, analytics reviews, and performance discussions.
Is conversion rate formal or informal?
Conversion rate is neutral and professional. It is used in both formal business reports and casual team conversations. It is standard terminology across all tech industries, so there is no risk of it sounding too casual or too formal.
What is the difference between conversion rate and conversion?
A 'conversion' is a single instance of a user completing an action (one person buys one item). 'Conversion rate' is the percentage or ratio of all conversions relative to all opportunities. If 100 people visit and 10 buy, there are 10 conversions and a 10% conversion rate.
Why is conversion rate important in tech companies?
Conversion rate directly impacts revenue and business growth. Even a 1% improvement in conversion rate can mean thousands of additional customers or dollars in revenue. This is why product teams, engineers, and marketers all focus heavily on optimizing it.
