Conversion rate: definition, calculation, and methods for improvement

What is the conversion rate?

Definition of conversion rate

The conversion rate representsthe proportion of people who have completed a specific action relative to the total population exposed or eligible for that action.

This action can vary significantly depending on the context:

• purchase;
• sign-up;
• download;
• quote request;
• appointment booking;
• account creation.

Let's look at a simple example.

A landing page receives 5,000 visitors.

150 people fill out the form.

The visitor-to-lead conversion rate is therefore:

150 ÷ 5,000 × 100 = 3%.

Conversion is therefore not necessarily a sale.

It all depends on the goal the company wants to measure.

In a B2B lead generation strategy, conversion can, for example, refer to a visitor moving from anonymous to anidentifiedlead.

Why is the conversion rate such a critical KPI?

The conversion rate helps distinguish betweenvolume and efficiency.

Let's look at two campaigns.

Campaign A

10,000 visitors.

100 conversions.

Conversion rate: 1%.

Campaign B

5,000 visitors.

150 conversions.

Conversion rate: 3%.

The first generates twice as much traffic.

But the second produces 50% more conversions.

Looking only at visits would therefore have led to an erroneous conclusion.

The conversion rate helps determine whether a stage in the journey effectively turns its audience into a result.

It also helps identify the main friction points.

For example:

high traffic + few leads → potential site conversion issue;

high leads + few opportunities → potential targeting or qualification issue;

high opportunities + few customers → potential issue further along in the sales process.

In what contexts is the conversion rate used?

The conversion rate can be used almost anywhere two successive stages can be compared.

In digital marketing:

visitor → sign-up

visitor → download

visitor → purchase

In lead generation:

visitor → lead

lead → MQL

In sales:

prospect → meeting

meeting → opportunity

opportunity → customer

In a sales pipeline, it even becomes possible to measure conversion between each stage to pinpoint exactly where opportunities are being lost.

Bon à savoir

Un « taux de conversion » doit toujours préciser ce qui entre et ce qui sort du calcul. Dire simplement « notre taux de conversion est de 5 % » reste difficile à interpréter si l’on ne sait pas s’il s’agit de visiteurs devenant leads, de leads devenant clients ou d’opportunités conclues.

How do you calculate the conversion rate?

The calculation is relatively straightforward. The real challenge lies in correctly choosing the numerator, the denominator, and the period being analyzed.

The conversion rate formula

The general formula is:

Conversion rate = Number of conversions ÷ Total number of eligible items × 100

For example:

Conversions: 80

Visitors: 2,000

Calculation:

80 ÷ 2,000 × 100 = 4%.

The conversion rate is therefore4%.

The same principle can be applied to a sales team.

Example:

200 sales opportunities

50 sales

Conversion rate:

50 ÷ 200 × 100 = 25%.

Calculation example

Let's look at a full campaign.

A company generates:

20,000 visitors

↓

1,000 leads

↓

250 qualified prospects

↓

100 opportunities

↓

30 customers

You can then calculate several conversion rates.

These different results answer different questions.

The visitor-to-customer rate provides a global overview.

Intermediate conversions help you understandwhere the main drop-offs occur.

How should you interpret the results?

A conversion rate must be interpreted within its context.

A drop is not always negative.

Imagine a company makes its form more demanding in order to better qualify leads.

Before:

1,000 visitors → 100 leads → 10 customers

Visitor-to-lead conversion: 10%.

After:

1,000 visitors → 60 leads → 15 customers

Visitor-to-lead conversion: 6%.

The landing page conversion rate has decreased.

But the number of customers has increased by 50%.

Optimizing only for the form conversion rate would have led to the wrong decision.

You must always compare a conversion tothe economic value of what it subsequently produces.

Bon à savoir

Une hausse du taux de conversion n’est pas automatiquement une amélioration business. Faciliter excessivement une conversion peut augmenter le nombre de formulaires tout en diminuant fortement la qualité des leads.

What are the different types of conversion rates?

The term covers several different metrics.

Website conversion rate

A website's conversion rate measures the proportion of visitors who complete an action considered important.

Depending on the company, this could be:

• a contact request;
• account creation;
• registration;
• a purchase.

A website can also have multiple conversions.

A B2B company might track the following separately:

content downloads;

newsletter sign-ups;

appointment requests.

It is therefore better to distinguish between these actions rather than grouping them into a single metric.

Landing page conversion rate

A landing page usually has a more specific goal.

For example:

page visit → form submission.

The calculation is quite simple:

Forms submitted ÷ Landing page visitors × 100.

Benchmarks published by Unbounce based on Q4 2024 data show a median of6.6% across all industries, based on a sample of 41,000 landing pages, 464 million visitors, and 57 million conversions. However, this figure varies significantly by industry: the SaaS benchmark presented by Unbounce, for example, drops to3.8%benchmarks are reference points, not universal goals.

A landing page simply asking for an email address and a page requesting a demo for a €100,000 contract obviously cannot be judged by the same expectations.

E-commerce conversion rate

In e-commerce, the primary conversion generally corresponds to a purchase.

The formula is often:

Number of orders ÷ Number of sessions or visitors × 100.

It is also possible to measure intermediate conversions:

product page → add to cart;

cart → checkout;

checkout → order.

This segmentation helps to identify the problem precisely.

A low add-to-cart rate may signal an issue with the offer or the presentation.

A very high abandonment rate at payment may indicate more friction in the checkout process.

Lead conversion rate

The lead conversion rate can measure several stages.

For example:

Lead → MQL

or:

Lead → Customer.

If a company generates 500 leads and 25 become customers:

25 ÷ 500 × 100 = 5%.

However, it can be more useful to measure each stage separately.

A MQL makes it possible to isolate an initial level of marketing qualification before handing it over to a sales-focused process.

Sales conversion rate

The sales conversion rate generally measures the proportion of prospects or opportunities that become customers.

Example:

80 opportunities → 20 sales.

Rate:

25%.

It can also be calculated by:

• salesperson;
• segment;
• source;
• product.

This helps identify significant differences.

For example, one channel might generate many opportunities but convert at a much lower rate than others.

Email campaign conversion rate

In email marketing, conversion must be precisely defined.

It can correspond to:

• a purchase;
• a sign-up;
• a download;
• a demo request.

One possible formula is:

Recipients who completed the action ÷ Emails delivered × 100.

However, some analyses focus more on post-click conversion:

Conversions ÷ People who clicked × 100.

Both metrics answer different questions.

The first evaluates the overall effectiveness of the campaign.

The second measures the ability of the landing page to convert people who are already engaged.

In a cold emailcampaign, it is therefore useful to distinguish between deliverability, replies, meetings, and final conversion rather than summarizing everything into a single rate.

What factors influence the conversion rate?

Conversion rarely depends on a single element.

Traffic quality

Not all visitors have the same probability of converting.

A company can attract a lot of traffic with very general content but end up with few relevant leads.

Conversely, a highly specialized query might generate fewer visits but reach prospects who are much closer to a buying decision.

The first question to ask when faced with a low rate is therefore not necessarily:

"How can I change the page?"

But rather:

"Are the right people landing on this page?"

Poor acquisition cannot always be fixed by conversion optimization.

The relevance of the offer

A perfectly built landing page will not convert well if the offer does not address the user's needs.

The value proposition must make it easy to quickly understand:

• what is being offered;
• who it is for;
• what problem is being solved;
• why the action is worth taking.

The smaller the gap between the visitor's need and the offer, the more natural the conversion becomes.

User experience (UX)

A poor experience creates friction.

Common issues include:

• confusing navigation;
• forms that are too long;
• poor mobile display ;
• unnecessary steps ;
• information that is hard to find.

A visitor might be interested in your offer but abandon it simply because the process requires too much effort.

UX must therefore facilitate action without removing the information needed to make an informed decision.

Calls to action (CTAs)

The CTA should clearly explain what happens next.

Compare:

"Submit"

with:

"Get the guide"

or:

"Book my demo".

The second type of phrasing provides more context.

The CTA must also match the level of maturity.

Asking:

"Talk to sales"

right away to someone reading a basic introductory definition might be too aggressive.

An intermediate resource might be more appropriate.

Trust and social proof

The more commitment required from a prospect, the more important trust becomes.

Reassurance elements can include:

• testimonials;
• case studies;
• reviews;
• references;
• guarantees;
• explanations regarding data processing.

An unknown company requesting significant personal information must give visitors enough reasons to trust them.

In B2B, a case study that precisely matches the prospect's industry can be particularly effective.

The speed of the purchasing journey

Every additional step can create a new opportunity for abandonment.

This does not mean that every process must be reduced to a single click.

However, every step must serve a purpose.

Regularly ask yourself:

"Is this information or step really necessary right now?"

A company that asks for fifteen fields in a form but only uses four of them afterwards is likely creating unnecessary friction.

How can you improve your conversion rate?

Optimization should start by identifying the friction point rather than by accumulating changes.

Optimize landing pages

A landing page must create a clear connection between the promise that generated the click and the content displayed.

Focus in particular on:

• headline;
• value proposition;
• benefits;
• social proof;
• CTA;
• form.

The hierarchy should allow visitors to quickly understand the offer.

Avoid having multiple goals on a single landing page.

A page designed to book a demo should not simultaneously offer ten competing actions.

Qualify leads more effectively

Improving sales conversion isn't just about selling better.

It may also be necessary to improvethe quality of the leads entering the pipeline.

For example:

100 opportunities → 10 customers = 10%.

After improving targeting:

70 opportunities → 14 clients = 20%.

The number of opportunities is decreasing.

But the number of clients is increasing.

The quality of your qualification process can therefore have a direct impact on sales performance.

A B2B lead generation agency can help by focusing on targeting and initiating conversations with companies that meet specific criteria.

Personalizing messages

A generic message tries to speak to everyone.

It often ends up speaking to no one in particular.

Personalization can be based on:

• industry;
• size;
• job function;
• pain points;
• level of maturity.

For example:

"Grow your sales"

is extremely general.

"Increase the number of meetings generated by your SaaS sales team"

addresses a much more specific situation.

The faster a visitor identifies with the proposition, the sooner they can grasp its relevance.

Run A/B tests

A/B testing involves comparing two versions of an element to see which one produces the best result.

It can apply to:

• headlines;
• CTAs;
• forms;
• value propositions;
• layout.

For example:

Version A: 8-field form

Version B: 4-field form

The test helps determine if simplifying the form actually improves conversion.

However, you must change few enough elements at a time to be able to interpret the results.

If you change the entire page at once, it is difficult to explain why one version performs better.

Reduce friction points

Every step of the journey must be examined.

Ask yourself, for instance:

• is the form too long?
• is the requested information necessary?
• is the CTA clear?
• is the page fast?
• is the mobile version easy to use?
• does the prospect know what happens after the action?

Some friction is obviously necessary.

A B2B form may require some additional information to filter out completely unqualified leads.

The goal is therefore notzero friction, butzero unnecessary friction.

Optimizing the conversion funnel

It is rarely enough to optimize only the first page.

The entire journey must be studied.

For example:

10,000 visitors

↓ 5%

500 leads

↓ 20%

100 opportunities

↓ 30%

30 clients

Suppose the company increases the first rate from 5% to 6%.

With other rates remaining constant:

600 leads → 120 opportunities → 36 clients.

It gains 6 clients.

But if it improves the opportunity-to-client conversion rate from 30% to 40% instead:

500 leads → 100 opportunities → 40 clients.

It gains 10 clients without increasing the initial volume.

This comparison shows why you must identifythe stage with the highest economic potential for improvement.

Bon à savoir

Optimiser la conversion ne signifie pas toujours travailler en haut du parcours. Une petite amélioration proche de la vente peut parfois avoir davantage d’impact sur le chiffre d’affaires qu’une forte augmentation du taux de formulaire.

What is a good conversion rate?

There is no universal figure that defines a good conversion rate.

Variations by industry

Performance varies significantly depending on:

• industry;
• price;
• requested action;
• channel ;
• visitor maturity.

The Unbounce benchmark based on Q4 2024 data shows a median of6.6% for landing pages across all industries, but the sectors covered in the study range from approximately3.8% to 12.3%. For SaaS, the stated median is3.8%, while business and professional services sit around6.1%in the same benchmark. These show why a general average should be used with caution.

A complex SaaS demo request and a free sign-up do not represent the same level of commitment.

Differences between B2B and B2C

In B2C, some decisions can be relatively quick.

The customer sees a product, compares the price, and buys immediately.

In B2B, the journey may require:

• multiple stakeholders;
• a demonstration;
• budget approval;
• negotiation.

The final conversion rate may therefore be lower at certain stages without necessarily indicating poor performance.

The sales value must also be taken into account.

Converting 1% of an audience into €50,000 contracts can generate much more value than converting 10% into €20 purchases.

The analysis must therefore reconcile:

conversion rate + value per conversion.

Why compare your own performance over time

Benchmarks are useful for establishing a baseline.

But the most actionable comparison is often your own history.

For example:

January: 2.8%

February: 3.0%

March: 3.4%

Even if the industry benchmark is higher, the trend shows improvement.

Also compare performance by:

• channel;
• device;
• segment;
• campaign;
• offer.

An overall average can mask significant differences.

A source at 1% and another at 8% can produce an acceptable average without immediately revealing the issue with the first one.

Which KPIs should you track alongside conversion rate?

Conversion rate must be compared with other indicators to get a complete picture.

Click-through rate (CTR)

CTR measures the proportion of people who clicked on an element out of those who were exposed to it.

It is primarily used for:

• advertising;
• email marketing;
• CTAs.

A high CTR but a low conversion rate after the click may indicate a lack of continuity between the promise and the landing page.

Bounce rate

Bounce rate can provide insights into engagement in certain analytics contexts.

A high level should be interpreted with caution.

A person might view a page, get exactly the answer they need, and then leave without it being a bad experience.

Therefore, bounce rate should be compared with:

• page type;
• time;
• conversions.

Customer Acquisition Cost (CAC)

CAC measures the cost required to acquire a customer.

Simplified formula:

Acquisition costs ÷ Number of new customers.

Improving the conversion rate can reduce CAC while keeping traffic or spending constant.

Example:

€10,000 in marketing spend.

Before: 20 customers.

CAC = €500.

After optimization: 25 customers.

CAC = €400.

The company acquires more customers without increasing its investment.

Customer Lifetime Value (CLV)

Customer Lifetime Value represents the total value generated by a customer throughout their relationship with the company.

It helps put the conversion rate into an economic context.

A segment with a lower conversion rate but much more profitable customers may be more valuable than a segment with a high conversion rate but low customer value.

Return on Investment (ROI)

ROI measures the profitability of the actions taken.

A conversion is only valuable if it contributes sufficiently to the bottom line.

A campaign can generate many leads with an excellent form submission rate while producing few actual sales.

ROI requires tracking performance further down the funnel.

Closing rate

The closing rate measures the proportion of sales opportunities that become customers.

Example:

50 opportunities → 15 customers.

Closing rate:

30%.

This KPI helps distinguish the ability to build a pipeline from the ability to close opportunities.

Here are the main complementary indicators:

The sales prospecting KPIs help round out this analysis when conversions relate more to the sales process.

Which tools can be used to measure the conversion rate?

The choice depends primarily on the stage being observed.

Web analytics tools

Analytics platforms allow you to track:

• visitors;
• events;
• forms;
• user journeys.

They are particularly useful for analyzing site-related conversions.

It is recommended to precisely define each important event.

For example:

form submitted;

account created;

purchase confirmed.

Without reliable tracking, the resulting rate can be misleading.

CRM

A CRM allows you to better measure the sales side of things.

It can track:

• leads;
• appointments;
• opportunities;
• sales.

A company can then calculate:

Lead → Opportunity

or:

Opportunity → Customer.

The CRM also facilitates segmentation by:

• salesperson;
• sector;
• source.

Marketing automation platforms

Marketing automation tools allow you to measure:

• forms;
• campaigns;
• emails;
• lead progression.

They can also trigger specific actions when criteria are met.

Certain sales automation functions can then automate tasks related to the sales process.

A/B testing tools

Experimentation tools allow you to compare multiple variants.

They are particularly useful for testing:

• CTAs;
• headlines;
• forms;
• page structure.

You need a sufficient volume of data before drawing conclusions.

Stopping a test after only a few conversions can lead to choosing a variant based purely on chance.

Reporting dashboards

When data comes from multiple tools, a dashboard helps you reconcile it.

For example:

Traffic → Leads → Opportunities → Customers → Revenue.

A sales prospecting dashboard can centralize key sales metrics and allow you to track their progress over time.

The goal is not to display as many metrics as possible.

A good dashboard helps you quickly understand:

where the problem lies and which action should be prioritized.

Common pitfalls

Several mistakes can lead to poor decision-making, even if the calculations are technically correct.

Focusing solely on traffic volume

Increasing traffic often seems like the first solution.

But if the page has a low conversion rate, buying more visits simply amplifies the inefficiency.

For example:

10,000 visitors × 1% = 100 conversions.

Doubling the traffic:

20,000 × 1% = 200 conversions.

But increasing the conversion rate to 2% also results in:

10,000 × 2% = 200 conversions.

In this simplified scenario, the same result is achieved without doubling traffic.

Ignoring lead quality

Making conversion easier can significantly increase the number of leads.

But if these rarely become customers, this improvement remains superficial.

You must therefore track the journey through to the final result.

For example:

Landing A: 8% conversion rate, but 2% of leads become customers.

Landing B: 5% conversion rate, but 10% of leads become customers.

The second one can be much more profitable.

Not segmenting your analytics

A general average can mask significant differences.

Segment by, for example:

• channel;
• campaign;
• device;
• audience;
• industry.

Suppose:

Desktop: 7%

Mobile: 2%

Overall average: 4.5%.

The overall figure does not immediately reveal the scale of the mobile issue.

Segmentation makes it possible to identify priorities much more precisely.

Neglecting optimization testing

Changing a page based solely on intuition might work, but it makes it difficult to identify what actually drove the improvement.

When volume allows, use structured experiments.

Formulate a hypothesis.

Example:

"Reducing the form from 8 to 5 fields will increase conversion without degrading lead quality."

Test it.

Then analyze both:

• conversion;
• quality.

This method avoids optimizing for an intermediate metric alone.

Comparing results to irrelevant averages

A benchmark can be very reassuring or very alarming without being truly comparable to your situation.

Unbounce explicitly points out that its landing page data analyzes conversion events, but not the individual economic value of each conversion: a rate lower than the median can therefore remain perfectly profitable when each conversion has a high value. For a comparison to be relevant, look at similar situations:

• same industry;
• same type of conversion;
• same channel;
• comparable price level.

Benchmarks should help you ask the right questions, not automatically dictate a goal.

Conversion rate FAQ

What is a conversion rate?

The conversion rate is the proportion of people who complete a desired action out of the total number of people exposed or eligible.

This action can be:

• a purchase;
• a sign-up;
• a form submission;
• a download;
• an appointment.

For example, if 100 people visit a landing page and 5 fill out the form, its conversion rate is5%.

How do you calculate a conversion rate?

The general formula is:

Number of conversions ÷ Total number of visitors, contacts, or opportunities × 100.

Example:

40 sales from 200 opportunities.

40 ÷ 200 × 100 = 20%.

Always use a denominator that truly corresponds to the stage preceding the conversion.

What is a good conversion rate?

There is no universal rate.

The level depends on factors such as:

• the industry;
• the channel;
• the price;
• the requested action;
• the level of maturity.

As a benchmark, Unbounce data from the fourth quarter of 2024 shows a median of6.6% for landing pages across all industries, compared to3.8% for SaaS landing pages. These figures do not mean that a 5% page is poor or that an 8% page is automatically excellent.

The value and quality of conversions must also be analyzed.

How can you increase your conversion rate?

Start by identifying the stage where you are losing the most prospects.

Then, work on:

• traffic quality;
• value proposition;
• UX ;
• CTA ;
• forms ;
• personalization ;
• lead qualification ;
• social proof.

Use testing when you have sufficient volume.

Finally, measure the impact beyond immediate conversion.

Successful optimization should ideally generate moremeaningful conversions, not just more superficial actions.

What factors influence the conversion rate?

The main factors are:

• audience quality ;
• offer relevance ;
• message clarity ;
• user experience ;
• trust level ;
• journey complexity ;
• prospect maturity.

Poor performance can therefore stem from the website, but also from the targeting or the offer itself.

What is the difference between conversion rate and transformation rate?

In many marketing and sales contexts,conversion rateandtransformation rateare used as synonyms.

Both measure the transition from one stage to another.

For example:

leads → customers

or:

opportunities → sales.

The term "transformation rate" is particularly common in sales terminology, while "conversion rate" is widely used in digital marketing.

The most important thing is not the term chosen, but the precise definition of the calculation.

A company must always specifywhich starting population is being converted into which final result.

It is this precision that allows the conversion rate to become a true management tool rather than just an isolated percentage.
