How it works
The formula is the number of conversions divided by the number of visitors or recipients, multiplied by 100. A conversion is whatever action you choose to count: a purchase, an email sign-up, a click on a link, a booked call. The definition must be exact, because sign-ups per visitor and purchases per visitor are very different numbers on the same page.
Conversion rate is useful because it separates two problems that feel the same. Low sales can come from too few visitors or from too few of them buying. The rate tells you which. It also lets you compare changes fairly. If a new headline lifts sign-ups from 2 in every 100 visitors to 3 in every 100, that is a real improvement whatever the traffic was that week.
The traps are in the interpretation. Rates vary enormously by traffic source, price, product and audience, so a benchmark from someone else's business tells you little. Small numbers mislead: one sale from twenty visitors is far too little data to rely on. And a higher rate is not always better. A page can convert more people by promising too much and then lose them to refunds. Judge the rate alongside revenue, refunds and the quality of the customers.
A worked example
A sales page had 1,000 visitors last month and 30 of them bought.
- Conversion rate: 30 / 1,000 x 100 = 3%.
- Break it down by source. Email subscribers: 400 visitors and 24 sales, or 6%. Social traffic: 600 visitors and 6 sales, or 1%.
- The page is not the main problem. Visitors who already know the creator buy six times as often as cold visitors.
- Next test: send social visitors to the free resource first, not straight to the sales page, and measure again.
An illustration, not a real account. Any numbers in it are made up to show the method, and are not benchmarks.
Common mistakes
- Comparing your rate with a benchmark from a different traffic source, price or product.
- Drawing conclusions from a few dozen visitors.
- Changing five things at once, so that you cannot tell what worked.
- Raising the rate with promises the product does not keep. Refunds will show it.
Questions people ask
How do I calculate conversion rate?
Divide the number of people who took the action by the number who could have, then multiply by 100. Be precise about both numbers: which action, which visitors, which period.
What is a good conversion rate?
There is no universal answer. It depends on the traffic source, the price, the offer and how the action is defined. The useful benchmark is your own rate last month.
How can I improve my conversion rate?
Match the page to what the visitor expected, make the offer and the next step unmistakable, remove distractions and answer the obvious objections. Then test one change at a time on enough visitors to trust the result.
