The Only 5 Metrics That Matter in a Product Launch Campaign

Launch recap decks are full of numbers that went up and to the right and mean almost nothing on their own. Impressions went up because you spent more. Reach went up because the algorithm rewards spend. None of that tells you whether the launch built a business. Here's what we actually track, in order of how early it tells you the truth.

The five that matter

• CAC by channel, not blended — a blended CAC hides the one channel that's quietly losing money and the one that's underfunded.
• Activation rate, not signup rate — a signup with no activation is a vanity metric with a login screen.
• Payback period — how many months until the customer has paid back what it cost to acquire them, which tells you if growth is fundable or just expensive.
• Qualified pipeline, not leads — a lead is a form fill; qualified pipeline is a lead your sales team would actually take a call with.
• Week-4 retention — the number that tells you whether the launch attracted the right customer or just the cheapest click.

Notice what's missing: impressions, reach, and engagement rate. They're not useless — they're diagnostic, not conclusive. If CAC is climbing, impressions can tell you whether the problem is the audience or the creative. But they never belong on the first slide of a recap, because they answer a question nobody asked, which is “did people see it,” instead of the one that matters, which is “did it work.”

We review all five weekly during a launch, not monthly. A campaign that's off track is much cheaper to fix in week two than to explain in the week-eight recap.
