Conversion rate measures the percentage of website visitors who take a specific action you want them to take.
It’s one of the most telling numbers on your website because it shows not just how many people visit, but how many of them actually do something.
What counts as a conversion?
A conversion is any meaningful action a visitor completes on your website. What that looks like depends entirely on what your site is trying to achieve. Common examples include:
✓ Making a purchase
✓ Filling in a contact or enquiry form
✓ Signing up for a newsletter
✓ Booking an appointment
✓ Downloading a file or resource
Each of these is a goal — and when a visitor completes one, that’s a conversion.
How is conversion rate calculated?
Like click-through rate, conversion rate is expressed as a percentage:
(Number of conversions ÷ Number of visitors) × 100 = Conversion Rate
So if 400 people visit your website in a month and 12 of them fill in your contact form, your conversion rate is 3%.
What is a good conversion rate?
It varies depending on the type of conversion and the industry. For e-commerce, a conversion rate of 1–3% is broadly typical. For simpler actions like newsletter sign-ups, you might reasonably expect higher.
As always, the most meaningful number is your own. Set a baseline, make improvements, and track what changes.
Why does conversion rate matter?
Traffic alone doesn’t tell the full story. You could have thousands of visitors every month, but if very few of them are taking action, something on your site isn’t working as well as it could.
Conversion rate helps you identify where that gap is. It shifts the focus from how many people visit to how well your website is doing its job.
It’s also worth remembering that improving conversion rate doesn’t necessarily mean redesigning your entire site. Sometimes small, targeted changes (like a clearer call to action or a more persuasive headline) can produce a meaningful uplift.
How do I improve my conversion rate?
There’s no single fix, but these are good places to start:
✓ Make your call to action clear and easy to find — visitors shouldn’t have to search for the next step
✓ Reduce friction — the fewer steps between a visitor and a conversion, the better
✓ Build trust — reviews, testimonials, and clear contact details all help reassure visitors
✓ Check your page speed — slow-loading pages lose visitors before they’ve had a chance to convert
✓ Optimise for mobile — a large proportion of visitors will be on a smartphone, and a poor mobile experience will cost you conversions
Conversion rate and CTR — better together
Conversion rate tells you what happens once someone arrives on your site. But getting them there in the first place is a different challenge — and that’s where click-through rate comes in.
