A 171× gap hiding inside one line of reporting
Two channels with nearly identical names in one account. One converted at 0.008%, the other at 1.448%. Blended reporting showed neither.
This is the clearest example we have of why blended reporting is dangerous, and it came out of an Airtel Payments Bank account that looked entirely unremarkable at the top line: 4,325,982 gross clicks, 523 conversions. A number like that justifies either cautious scaling or quiet cancellation, and either decision would have been wrong.
What the blended number concealed
The account contained two offers with nearly identical names. The main Airtel Payments Bank offer produced 366 conversions from 4,315,140 gross clicks — a 0.008482% conversion rate. The ShareIt integration produced 157 conversions from 10,842 clicks — 1.448072%. That's a 171× difference between two lines sitting next to each other in the same account.
Put differently: 30% of the account's total conversions came from 0.25% of its clicks. Every strategic question about that account changes depending on which of those two realities you're looking at, and the blended view showed neither.
Why this happens so often
Nobody sets out to hide this. It happens because reporting defaults aggregate, dashboards default to account level, and a line item with a familiar name doesn't invite scrutiny. The two Airtel offers looked like the same thing with a suffix. Most reporting reviews would read the total and move on — which is exactly what had been happening.
The tell is usually a conversion rate that seems implausibly low for a product you'd expect to convert better. A 0.008% rate on a payments product from a major telco isn't a market reality, it's a signal that something inside the aggregate is dragging the average down and something else is being masked by it.
What we changed
Splitting the offers apart reframed the entire engagement. The question stopped being "how do we improve a 0.008% conversion rate" and became "how far can integrated placement like ShareIt scale before it saturates." Those lead to completely different media plans, and only one of them is worth funding.
The general rule we now apply to every account we inherit: before optimising anything, split every line that could plausibly contain two different businesses and look at them separately. It costs an afternoon and it's found something material more often than not.
