Why Google and Meta Are Lying About Your Ad Results (And Wasting 30% of Your Budget)

If you spend $20,000 a month on ads, $4,000 to $6,000 of it is probably being wasted. And your ad reports will never show you where it went.In this episode of The Agency Insider Show, I sit down with Anni Kristiina Salo, CEO of Tracklution, a server-side tracking platform out of Helsinki, Finland, growing at over 60% year on year. Before this, Anni built an in-house tracking solution that helped scale and sell one of Finland's biggest broker platforms. She has seen exactly how ad platforms inflate their numbers, and more importantly, why.Here is the uncomfortable math: Google says it drove 100 conversions. Meta says 80. TikTok says 40. But the client's backend shows only 120 total sales. Every platform is taking credit for the same customer. So who is telling the truth?Anni breaks down why the platforms overattribute, who is actually feeding the algorithm bad data (hint: look in the mirror), and the exact steps to stop wasting 20 to 30% of your ad budget.In this episode:Why Google and Meta report numbers that do not add up, and why that is by designThe $6,000 a month leak hiding inside a typical $20K ad accountWho is really feeding the algorithm bad data (it is not who you think)Why your tracking pixel is a black box with no audit trailThe real client story: 17 to 19% lower customer acquisition cost and 25% more new customers after fixing the data3 types of first-party data you already have but are not using: profit margin, CRM data, and new vs returning customersHow to track offline sales, like a clinic booking that turns into a $500 purchase weeks laterCross-device attribution: how close are we to actually solving itThe counterintuitive reason you might WANT platforms to overattributeWhether you are an agency owner, a performance marketer, or a CMO trying to figure out why your numbers do not add up, this one is a masterclass.CHAPTERS0:00 The hook: where 30% of your ad budget really goes0:43 Anni's journey: from fintech to fixing tracking3:20 Built inside a lead gen agency out of real pain5:22 From internal tool to global product with a team of 167:08 Server-side tracking in 5 minutes: too good to be true?9:30 Who actually owns tracking inside a company11:21 How agencies should handle clients with broken tracking14:17 What happens when you feed algorithms bad data17:34 Not all conversions are equal: choosing the right signals19:50 Real case study: meal kit brand cuts acquisition cost by ~20%24:40 The 3 first-party data goldmines you are sitting on26:55 Closing the loop on offline sales29:59 Which platforms punish bad data the most31:40 Google says 100, Meta says 80, backend says 120: the attribution mess36:00 Cross-device tracking: can it actually be solved?38:30 Building data literacy inside your agency team40:29 The final number: how much a $20K/month advertiser is wasting
