Practice · Spot the Marketing Leak
Can you spot where a business loses money?
Practice spotting where a made-up business loses money between the ad and the real call.
Have ready: nothing. The cases and the numbers are made up.
Your game
What you type in this tool stays in your browser.

See an example
| What you enter | Value |
|---|---|
| Case | 48 conversions, 19 inquiries |
| Made-up ad spend | $2,400 |
| Actions the ad site reported | 48 |
| Calls and forms the office logged, from all sources | 19 |
| What you get | Value |
|---|---|
| Ad site math | $2,400 divided by 48 = $50 per reported action |
| What that does not show | A $50 cost per real call or form |
| What the office count cannot do | Show how the ads did, because it covers all sources |
Check what each count means and where the calls came from before you treat either number as the answer.
What this means
The ad site and the office are counting different things. Neither number alone tells you what a real call from the ads cost.
Details: what this challenge can’t do, and how we handle your information
What it can’t do
- Cases are simpler than real life, and important facts may be missing. No real website, account, staff member or campaign is looked at.
- The 2, 1 and 0 teaching points apply to these cases only. Your confidence and choices are not a test of you, your staff or your business.
- We have not run a study with players or measured how well it teaches. There is no leaderboard, time penalty, account or email needed.
