What one sale or enquiry is worth to your business on average.

So here's how your website's performing

What this SEO ROI calculator shows you

Most business owners know roughly how much traffic their website gets, but few have ever put a number on what that traffic is actually worth. This free SEO ROI calculator does it in seconds. Give it your monthly visits, your monthly sales or enquiries and the average value of each one, and it works out your conversion rate and the total value your website adds to your pipeline every month.

Then it does the interesting bit. It shows what happens to that number when you grow your traffic. Hold your conversion rate and average value steady, add a modest lift in visits, and the extra revenue quickly adds up. That gap between where you are now and where you could be is the case for investing in SEO. Built by The Digital Maze for clients and the wider marketing community.

The numbers this tool works out

Conversion rate

Your sales or enquiries divided by your visits. If 10 out of 1,000 visitors convert, that is a 1% conversion rate. It tells you how well your website turns interest into action.

Conversions

The number of visits that become a sale or an enquiry each month. This is the figure that pays the bills, so it is the one worth growing.

Average value

What a single sale or enquiry is worth to your business. For ecommerce that is your average order value. For lead generation it is the average value of a closed enquiry.

Total monthly value

Conversions multiplied by average value. This is the revenue, or pipeline, your website contributes every month. Multiply by twelve for the annual picture.

The traffic uplift

What happens when you add 20%, 30%, 40% or 50% more visits. Conversion rate and average value stay the same, so the extra revenue comes purely from reaching more of the right people.

The gap

The difference between your current value and the projection. That gap is the commercial reason to invest in growing your organic traffic.

How to grow each number

Is this calculation accurate?

It is a model, not a guarantee. It assumes your conversion rate and average value stay roughly the same as you grow, which is a sensible starting point. In reality the mix of traffic you attract, seasonality and how well your site converts will all move the final figure. Treat the result as a realistic ballpark of the opportunity, not a promise. The point is direction and scale, and on both counts more of the right traffic is almost always worth having.
