What is conversion rate?

Conversion rate is the percentage of users who complete a desired action out of the total number of visitors, sessions or clicks.

Conversion rate formula

Conversion Rate = (Conversions ÷ Visitors) × 100

For example, if a page receives 2,000 visitors and 50 of them convert:

(50 ÷ 2,000) × 100 = 2.5%

That means the page has a 2.5% conversion rate.

When to use a conversion rate calculator

A conversion rate calculator is useful when you want to measure how effectively your traffic turns into results. Common use cases include:

• website lead generation
• e-commerce sales tracking
• PPC landing page analysis
• email campaign performance
• sign-up page optimisation
• affiliate and funnel reporting

Example conversion rate calculations

Example 1: E-commerce sales

A shop gets 5,000 visitors and makes 125 sales.

Conversion rate = (125 ÷ 5,000) × 100 = 2.5%

Example 2: Lead generation

A landing page receives 800 visitors and generates 32 enquiries.

Conversion rate = (32 ÷ 800) × 100 = 4%

Example 3: Newsletter sign-ups

A blog post attracts 1,250 visits and gets 25 sign-ups.

Conversion rate = (25 ÷ 1,250) × 100 = 2%

Why conversion rate matters

Conversion rate helps you understand whether your page or campaign is actually working. A strong conversion rate can mean:

• your offer is relevant
• your targeting is accurate
• your page experience is clear and persuasive
• your traffic quality is good

A weak conversion rate can suggest problems with intent, messaging, design, speed, pricing or trust signals.

What is a good conversion rate?

There is no single “good” conversion rate for every website. It depends on your industry, traffic source, offer and audience. For example:

• e-commerce sites may see lower rates than high-intent lead forms
• branded traffic often converts better than cold traffic
• mobile traffic may convert differently from desktop traffic

The key is to compare performance over time and benchmark similar campaigns rather than relying on a single universal number.

Tips to improve conversion rate

If your conversion rate is lower than expected, consider testing:

• stronger headlines and calls to action
• shorter forms
• faster page load speed
• clearer product or service benefits
• better mobile usability
• more relevant traffic sources
• social proof, reviews and trust badges
• simpler checkout or enquiry flows

Conversion rate vs click-through rate

These metrics are often confused, but they measure different things:

• Click-through rate (CTR) measures how many people click after seeing a link or advert
• Conversion rate measures how many people complete the final desired action

A campaign can have a high CTR but a poor conversion rate if the landing page does not match user expectations.

Conversion rate vs bounce rate

Bounce rate shows how many users leave without further interaction, while conversion rate tracks successful outcomes. Both metrics can be useful, but conversion rate is usually closer to commercial performance.

Frequently asked questions

How do you calculate conversion rate?

You divide the number of conversions by the number of visitors, sessions or clicks, then multiply by 100.

What counts as a conversion?

A conversion is any desired action, such as a sale, sign-up, form submission, booking or download.

Should I use visitors, sessions or clicks?

Use the traffic measure that matches your reporting source. For website analytics, sessions are often used. For ad campaigns, clicks may be used. Just stay consistent.

Can conversion rate be over 100%?

It can happen in some reporting setups if multiple conversions are attributed to the same visitor or session. In many standard website scenarios, conversion rate is below 100%.

Why is my conversion rate 0%?

That usually means there were no conversions recorded, or that the number of visitors is much larger than the number of conversions.

Is a higher conversion rate always better?

Usually yes, but context matters. For example, tighter targeting may reduce traffic volume while improving conversion rate. It is best to assess both efficiency and total results.
