Marketing
ROI
Return on investment.
// What it is
(Revenue minus cost) divided by cost, times 100. How much you earn per euro spent.
// Why your business should care
If an agency shows you engagement, impressions, and reach but never ROI, they can't prove they're making you money.
// Common myth
"We have high engagement." Great. How much of that turned into euros?
Verdict:
The only metric that ultimately matters.
