FY Closing Checklist: Are You Auditing Ad Fraud Media Waste Before Budget Reset?
It’s that time of year again. Finance wants numbers. Leadership wants plans. And marketing teams across the country are doing what they do every time during financial year close: reviewing channel spends, comparing ROAS across platforms, and deciding where next year’s budget should go.
But here’s what most of those budget conversations skip.
Channel-level reporting tells you what you spent. It doesn’t tell you whether any of it actually worked the way you think it did.
The uncomfortable reality is that media waste doesn’t happen only in bad channel choices or poorly targeted campaigns. It happens at every stage of the funnel:
Impressions served but never seen
Clicks generated by bots or non-intent traffic
Visits that never engage
Conversions that were misattributed or would have happened organically
This means a vast majority of media advertising budget wastage, and ad fraud is invisible without deliberate, layer-by-layer auditing.
As you close the financial year and plan for FY 2026, the most important question is not just where to spend more, but where your budget may already be leaking.
The Full-Funnel Media Waste Audit Checklist
To ensure your next year’s budget is based on reliable performance data, marketers should audit campaigns across four key stages:
Impressions (Reach & visibility)
Clicks (Traffic quality)
Visits/Installs (Real engagement)
Events/Conversions (True business outcomes)
Below is a structured financial-year closing audit checklist for each stage.
Impressions & Reach Stage
You Paid for Reach. But Did Real People See It?
Impressions are hardest to tie to outcomes and often get ignored while auditing ad traffic. It is because an ad delivered is often considered to have been viewed. As per IAB viewability standards, if a static ad is visible on the screen for a continuous one second, the impression is counted as served.
However, delivered is not the same as seen. And seen is not the same as seen by the right person, in the right place, at the right moment. If you’re not actively auditing where your impressions are going, which placements, which audiences, which environments, you’re not running a branding campaign. You are just running a reach report.Â
What Advertising Budget Waste Looks Like At The Impression StageÂ
Invalid Traffic (IVT):Â Bot-generated impressions consuming budget and reporting as delivered.
Viewability failures:Â Ads technically served but never actually in-view by humans.
Brand safety violations:Â Impressions delivered in unsafe or irrelevant content environments.
Pixel stuffing:Â Multiple ads hidden within a single placement or tiny pixel, generating impressions that users never actually see.
Ad stacking:Â Multiple ads layered on top of each other in a single placement, with only the top ad visible while all register impressions.
Audience mismatch:Â Impressions served outside your target demographic, geography, or intent band.
Frequency breaches:Â Ads repeatedly served to the same users beyond frequency caps; inflating impression counts without increasing incremental reach.
Made-for-Advertising (MFA) sites:Â Low-quality publisher sites designed primarily togenerate ad impressions rather than genuine user engagement.
Here’s what we saw in one of the campaign audits for a FMCG brand
A full-funnel audit conducted on an FMCG brand campaign running across placements over a four-week period, revealed something that the campaign dashboard simply wasn’t showing.
At first, the numbers looked fine. Impressions in the millions, a 1.43% CTR, and IVT at 3.4%. But the real signal was buried in the visit-to-click ratio: of every 100 clicks recorded, fewer than 48 resulted in an actual website visit.
More than half the clicks were going nowhere. Digging deeper into placement-level data made the picture significantly worse. Out of 4,859 total placements generating impressions, 92.98% of placements generated zero clicks further.
