Start With the Goal

ROI depends on what the campaign is meant to achieve: leads, sales, signups, awareness, or retention.

Track Campaign Costs

Include ad spend, tools, content, freelancers, and internal time when possible.

Define Conversions

A conversion may be a purchase, form submission, booked call, newsletter signup, or qualified lead.

Avoid Attribution Perfection

Attribution is rarely perfect. Use a practical model that helps make better decisions.

Build a Simple Report

Track spend, traffic, conversions, conversion rate, cost per conversion, and revenue where available.

FAQ

Is ROI always financial?

Not always. Some campaigns support awareness or education, but financial outcomes should still be considered over time.
