What a Small Uplift Delivers
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 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?
A straightforward managed test typically costs around £192.50 to £250. 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.
