<b>The decision built on 12% of the truth</b>
A large publisher killed a content category after a report showed it underperforming on conversions. The cut felt data-driven and final.
The clue came when an analyst noticed the small print: the date range was wide enough that the report had triggered data sampling, basing the verdict on roughly 12% of sessions, and that sample happened to undercount a high-converting weekend cluster.
They re-ran the same question in shorter, unsampled windows and stitched the results.
The category's real conversion rate came back at 3.6%, not the sampled 1.1%, and it moved from the chopping block to a small investment.
The lesson: a sampling notice on a report is a warning label. Shorten the range or export raw before you make a permanent cut from a partial truth.
