What Is Digital Advertising? Measurable, and Not the Same as Accountable

In plain English

Search, social, display, video, retail media, connected television. What unites them is that everything can be counted, which is both the advantage and the trap.

Counted is not the same as caused. Platforms report the conversions they can see and claim, which systematically overstates their own contribution.

What to know

Many channels

Search, social, display, video, retail, audio.

Measurable

Every impression, click and conversion recorded.

Auction-priced

Cost rises with competition.

Self-reported

Each platform claims what it can attribute.

Why it matters

The discipline that matters is comparing platform-reported results against your own total revenue. When every channel claims sixty percent of the sales, none of them are telling you the whole truth.

Common mistakes

×Adding up platform-reported conversions as if they were distinct.

×Optimising to a metric the platform chose for you.

×Ignoring incrementality entirely.

×Assuming cheaper clicks mean better results.

FAQs

Why do platform numbers exceed my actual sales?

Because each claims credit for conversions it touched. Overlap is inevitable.

How do I know what advertising is really contributing?

Holdout tests, and watching total revenue against total spend.
