What Does Your TACoS Tell You?
If your TACoS is falling over time while ACOS stays flat, your organic sales are growing — a sign that advertising is building brand momentum rather than just buying revenue.
A high TACoS with a low ACOS means most of your sales are organic — advertising is efficient but not the growth driver.
A high TACoS with a high ACOS means advertising is expensive and not well supported by organic sales — the most dangerous position.
