Even a 0.1% uplift could add about £200 per month from the traffic you already have.
If you run an ecommerce site, you might wonder if conversion rate optimisation is worth the effort. This page gives you a practical worked example using simple maths, so you can see what small improvements could mean for your ecommerce revenue.
This is not about buying more traffic. It is about getting more value from the visitors you already have. For the broader principle, see how to make your website work harder. If those visitors come from paid ads, see how landing page testing can help you get more leads from the same ad budget.
Use the calculator below to estimate how much extra monthly and annual revenue even a small improvement in conversion rate could generate.
Try Your Own Numbers
Use your own traffic, conversion rate, and order value to estimate what a small uplift could mean for your business. Adjust the numbers below and see the impact instantly.

What a Small Uplift Delivers
What to Expect in Reality
Most tests do not produce dramatic wins. Some deliver small gains, and some mainly provide useful learning. Over time, steady improvements and insights can build into meaningful growth in orders and revenue. The examples above show how even modest uplifts can add up.
What Does a Test Cost?
In many cases, even a modest improvement could recover the cost of a managed test within a relatively short period, depending on your traffic and average order value. In this example, even a 0.1% uplift could add about £200 per month. That means a modest improvement could recover the cost quickly and continue adding extra revenue after that.
Learning and Iteration Matter
Conversion rate optimisation is not about chasing huge wins every time. It is about steady, practical improvement and learning what works for your customers. Over a year, a few small uplifts and useful insights can compound into a meaningful increase in monthly revenue. See how this could look in a 12 month CRO roadmap.
