What marketing ROI means

Marketing ROI compares what is spent on marketing against the commercial result that spend creates.

Why this is difficult for SMEs

Smaller businesses often do not track campaigns with enough discipline, which makes performance feel subjective rather than measurable.

What to measure

  • Spend by channel
  • Leads or enquiries
  • Conversion rate
  • Revenue impact
  • Margin contribution where possible
