ROI tells you whether marketing earns more than it costs. You do not need complex tools, only honest tracking.
The simple formula
Marketing ROI = (revenue from marketing − marketing cost) divided by marketing cost. Use real sales that came from tracked leads.
What you must track
- Where each lead came from
- How many leads became customers
- Average value of a customer
- Total spend including fees
Set up tracking
Use GA4 for website actions, call tracking numbers, form tracking and a simple sheet or CRM where staff record the lead source.
Look beyond the last click
Many customers see an ad, search your name later and then call. Ask every new customer how they found you and add that answer to your report.
Frequently asked questions
Which metric matters most?
Cost per customer, not cost per click or likes.
How often should I check?
Check weekly for ads and monthly for the overall picture.
