How the calculation works
Enquiries equal visitors multiplied by the website conversion rate. Estimated customers equal enquiries multiplied by the close rate. Estimated revenue equals customers multiplied by average customer value. This is a planning model, not a forecast: traffic quality and sales capacity still matter.
What to do with the result
If a modest conversion improvement creates more value than doubling traffic, fix the website first. If the page already converts qualified visitors well, invest in SEO for compounding traffic or Google Ads for speed.
