Website Conversion Rate

Percentage of website visitors who complete a desired action (form fill, demo request, sign-up)

What is Website Conversion Rate?

Website conversion rate is the percentage of website sessions that end in a chosen goal, such as a purchase, a form submission or a sign-up. It shows how well a site turns visitors into results.

It is one of the most valuable measures in digital marketing because improving it raises results without needing more traffic. Small gains in conversion often deliver more than large increases in spend.

How this KPI is measured

Function: Marketing
Sub-function: Web & SEO
Industry: All Industries
Type: Lagging
Impact: Efficiency
Unit: %
Measurement frequency: Weekly / Monthly
Formula: (Conversions on site / Total sessions) × 100

How to calculate it

Divide the number of conversions by the total number of sessions, and multiply by 100.

For example, if a site had 40,000 sessions in a month and 800 of them ended in a completed enquiry form, the conversion rate is (800 / 40,000) x 100 = 2%.

Define what counts as a conversion before you measure, and track different goals separately. Rates vary widely by traffic source, device and page type, so the overall figure is best used as a starting point for deeper analysis.

Where it is used

Improving the site
Test changes to pages and forms and see whether they lift the share of visitors who act.
Judging traffic quality
Compare conversion by source to see which channels bring visitors who take action.
Forecasting results
Combine expected traffic with the conversion rate to estimate leads or sales.

How to improve it

Define the conversion goalsSet up tracking for each meaningful action, such as enquiries, purchases and downloads.
Find where visitors drop outLook at the pages and steps where most people leave, and focus on those.
Simplify forms and journeysRemove fields and steps that are not essential, and make the next action obvious.
Improve clarity and trustState the offer plainly and add proof such as reviews, guarantees and customer names.
Run controlled testsCompare versions of key pages with enough traffic to be sure which performs better.

Tips and common mistakes

Segment by device. A healthy desktop rate can hide a poor mobile experience.
Do not chase the rate at the expense of quality. More sign-ups of the wrong people help nobody.
Give tests time and traffic. Stopping early on a lucky result leads to wrong conclusions.
