What the result means

A website is not a cost with a design attached; it is a salesperson with a conversion rate. If a rebuilt site lifts conversion from 1% to 2.5% on the same traffic, it produces the extra revenue above every year without a dollar more spent on ads. Set that against a one-off build fee and the payback period is usually measured in months. To see what a build costs, run the website cost calculator or read what a custom website costs.

Common questions

How do you calculate the ROI of a new website?

Multiply monthly visitors by conversion rate to get leads or sales, then by close rate and average sale value to get revenue. Compare that at your current conversion rate and at an improved one; the difference over a year, set against the build cost, is the return.

What is a good website conversion rate?

Marketing sites typically convert 1 to 3 percent of visitors into enquiries. Well-designed sites with clear offers and fast load times can reach 5 percent or higher. Ecommerce commonly sits at 1 to 2 percent of visitors into purchases.
