Conversion rate

Conversion rate is the percentage of a defined audience that completes a chosen action, such as buying a product, submitting an enquiry or booking a call.

A business can attract thousands of website visits and still receive very few enquiries. Another can reach a smaller audience and generate a steady flow of worthwhile conversations. Conversion rate helps explain that difference. It measures how often an audience completes an action that matters to the business.

The action might be a purchase, an appointment booking or a completed enquiry form. It might also be an earlier step, such as starting a trial. The useful question is always the same: out of the people who had the opportunity to act, how many did?

How do you calculate conversion rate?

The general formula is: conversion rate = conversions ÷ the relevant audience or interactions × 100. The denominator needs to match the question. A website report might use sessions, a product report might use users, and an advertising platform might use eligible ad interactions.

If a service page receives 2,000 sessions and generates 40 enquiries, its enquiry conversion rate is 2%, using enquiries divided by sessions. If a shop receives 80 orders from 4,000 sessions, the order conversion rate is also 2%. These numbers share a formula, but they describe different business outcomes.

Google Ads defines its conversion rate using tracked ad interactions. Its figure can therefore differ from a website analytics report even when both systems are working as intended. Compare the definitions, attribution settings and time periods before treating a discrepancy as an error.

What counts as a conversion?

A conversion is an action you have chosen to measure. It does not become commercially valuable simply because a dashboard calls it a conversion. A button click, a submitted form and a signed contract sit at very different points in the customer journey.

For a B2B company, it is useful to distinguish an initial enquiry from a qualified opportunity. A form submission might come from a prospective customer, a recruitment agency or a supplier. Counting all three equally can make marketing performance look stronger than the underlying sales pipeline.

For an online shop, a completed order is usually more meaningful than adding an item to a basket. Both can be measured, but they should be reported separately. Earlier actions help diagnose the journey; final outcomes help judge its commercial result.

What is a good conversion rate?

There is no single percentage that every website should aim for. A visitor buying a familiar, inexpensive product faces a different decision from someone choosing a business partner for a substantial project. The commitment, price, audience and source of traffic all change the context.

Start with your own comparable baseline. Examine the same conversion action, using the same measurement method, across similar periods and traffic sources. A useful comparison might be mobile enquiries from non-brand paid search this quarter against the previous quarter. Comparing that audience with returning customers responding to an email offer would say much less about the page itself.

Industry benchmarks can help frame questions, but they rarely explain what is happening inside a particular business. A lower conversion rate can coexist with stronger revenue if the company begins attracting larger, more valuable projects.

Why might conversion rate fall?

A decline can have several causes. Traffic may have broadened to include people who are researching rather than ready to buy. A campaign might promise something the destination page does not clearly deliver. A form might be failing on certain devices. Measurement may have changed after an analytics update.

Before redesigning the page, check whether the audience or tracking changed. Then break the journey into stages. Are people reaching the page? Are they finding the relevant information? Are they starting the form? Are they completing it? A fall at one stage gives a more useful starting point than an overall percentage.

Also consider timing. Some businesses receive enquiries weeks after a first visit. A short reporting window can make recent traffic look less productive because part of the sales cycle has not yet happened.

How can you improve conversion rate?

Begin by making the offer understandable. Visitors should be able to establish what the business does, who it helps and what the next step involves. Specific service descriptions and relevant evidence usually provide a stronger basis for a decision than broad claims about being innovative or passionate.

Review the effort required to take that next step. Forms should ask for information the business can justify collecting at that stage. Buttons should describe what happens next. Confirmation messages should explain whether someone will reply and what the visitor can expect.

Use conversion rate optimisation to investigate and test improvements. A dedicated landing page can help align a particular campaign with a particular offer, while responsive web design helps make that journey usable across screen sizes.

Conversion rate, revenue and lead quality

Increasing the percentage is useful only when it supports the right outcome. Removing every qualifying question from a form could increase submissions while creating more unsuitable enquiries. A deep discount could improve purchase conversion while reducing the contribution from each order.

Pair conversion rate with measures that reflect the business model: qualified leads, cost per qualified enquiry, sales acceptance, average order value, contribution or revenue per session. This gives the percentage a commercial context and helps prevent an attractive report from masking a weaker result.

Common questions about conversion rate

Is conversion rate the same as click-through rate?

No. Click-through rate measures the proportion of impressions that produce clicks. Conversion rate measures completion of a chosen action among a defined set of users, sessions or interactions. A campaign can attract clicks without producing worthwhile enquiries.

Can conversion rate exceed 100%?

It can in some reporting systems when several conversions can be counted from one interaction. Google Ads explicitly allows this in certain counting configurations. A rate based on the share of users who converted at least once cannot exceed 100%.

How often should you review it?

Review frequently enough to catch broken journeys, but evaluate performance over a period that produces meaningful volumes. A small number of conversions can make short-term percentages fluctuate sharply. Record changes and compare like with like.

A practical example

Illustrative example: an engineering company records 30 enquiries from 1,500 sessions, giving a 2% enquiry conversion rate. Twelve become qualified opportunities. Tracking both figures reveals whether future changes improve the sales pipeline as well as the volume of forms.

Why it matters

Conversion rate connects website activity with a defined outcome. Used alongside lead quality and revenue, it helps a business distinguish a traffic problem from a journey problem and decide where improvement work will be most valuable.
