You spend on ads every month. You're getting clicks. But asked "which ads actually drove sales?", you can't answer clearly. That happens at a lot of online stores — and it's rarely a skill problem. It's usually a missing measurement foundation.
TL;DR
Ad effectiveness is whether ads drove *sales* — not clicks or impressions
You can't tell which ads worked because the foundation is missing — no conversion tracking, no UTM tags, no link between ads and revenue
Platform dashboards stop at "what happened" — your real revenue and whether buyers were new aren't there
