What is conversion rate?

The percentage of visitors, users, or recipients who complete a desired action — conversions divided by the audience.

What is a good conversion rate?

It depends on the action, traffic, and industry — compare like-for-like definitions and your own baseline rather than universal benchmarks.

How do you improve conversion rate?

A/B-test the funnel's friction points, match message to traffic intent, and segment honestly before crediting any change.

Share completing the action.

"The new checkout lifted conversion rate from 2.1% to 2.9%."

Definition in plain terms

Conversion rate is the percentage of people who complete a desired action out of those who could have: buyers among visitors, signups among trial starts, clicks among recipients. One hundred visitors, three purchases — a 3% conversion rate. Every funnel step has one.

The mechanics

The formula is conversions ÷ audience, but the denominator is a decision: per session, per user, per click? Comparisons only hold when the definition matches. Rates move with traffic quality and intent as much as page design — a "worse" page fed by warmer traffic will beat a better page fed by cold clicks. That's why conversion work pairs A/B testing with honest segmentation.

When it matters

Conversion rate matters because it multiplies everything upstream: doubling it doubles the value of every visitor you already pay for. It's the core metric of CRO, checkout design, and landing pages. The traps: chasing rate by filtering out all but hot traffic (rate up, volume down), and comparing rates across sites, channels, or definitions where the denominators differ.

Worked example. An ecommerce team agonizes over a rival's reported 6% conversion rate against their 2.5% — until they notice the rival counts per user while they count per session, and the rival's traffic is mostly returning customers. Like-for-like, the gap nearly vanishes. They refocus on their own funnel, where an A/B-tested checkout fix lifts conversion 0.8 points — worth more than the comparison ever was.

Failure modes to watch. Comparing rates with different denominators; juicing rate by excluding cold traffic instead of converting it; optimizing micro-conversions that don't lead to revenue; and reading a rate shift without checking traffic mix first.
