At a glance

The alert that catches runaway budget on a broken or fatigued creative before it eats the week. It watches each ad set for a burst of zero-conversion spend over a rolling 72-hour window and fires when that spend crosses a configured floor. Where the steady-state Wasted Spend card reports the cumulative total, this card is the early-warning version: it fires on the recent spike, not the long tail, so the team can pause the offending ad set the same day. Caveat: a burst of zero-conversion spend can be a tracking break rather than a genuinely failing creative, so confirm against CAPI/Pixel Tracking Broken before pausing.

Calculation

Calculated automatically from your Meta Ads (Facebook) data. See the At a glance summary above for what the metric tracks and the worked example below for a typical reading.

Worked example

A UK skincare brand running several ad sets under one Advantage+ campaign. Reading taken at 14:00 on 14 Mar 26. Account currency GBP. The configured 72-hour floor is illustrative.
  1. Two ad sets fire. Video B and the Lookalike static each ran three days of spend with zero attributed conversions above the floor. The test ad set also has zero, but its £70 is below the floor and is suppressed as expected noise.
  2. The two fires have different causes. Video B is a brand-new creative that never converted from day one, which usually means a broken or mis-targeted landing link in the ad. The Lookalike static converted last week and stopped, which is the fatigue pattern. Same alert, different fix.
  3. Confirm it is not a tracking break first. If CAPI/Pixel Tracking Broken is also firing, the zero conversions may be unmeasured rather than absent. Check that before pausing, otherwise you pause an ad set that is actually working.
  4. The cost of waiting is the whole week. £760 plus £410 over three days projects to roughly £2,700 a week if left running. That is budget that could move to the healthy cold-video-A ad set.
  5. The action is a pause, then a diagnosis. Pause both flagged ad sets to stop the bleed, then fix Video B’s link and refresh or retire the fatigued Lookalike creative. Reactivate once corrected.
Quick reads:
  • New ad set + zero conversions from day one = broken link or mis-targeting. Check the destination URL.
  • Established ad set + conversions stopped = fatigue. Refresh the creative.
  • Zero conversions + tracking alert also firing = suspect measurement, not the creative.
  • Below floor = ignore. It is test-budget noise by design.

Reconciling against Meta Ads Manager

Where to look in Meta Ads Manager: Meta Ads Manager → Ad sets with the date range set to the last 3 days, the “Amount spent” and “Purchases” (or “Results”) columns visible, and sorted by spend. Filter to ad sets with purchases equal to zero. Meta does not surface a “wasted-spend burst” alert natively, so you reconstruct it by reading the spend-with-zero-results rows. Match the attribution setting to this card’s configured window. Other Ads Manager views that look related but are not:
  • Cost per result: Meta hides the row or shows a dash when results are zero, which is exactly the case this card surfaces. The dash is easy to scroll past; the alert is not.
  • Delivery status: an ad set marked “Active, Learning Limited” may spend without converting; this card catches the spend regardless of the delivery label.

Known limitations / merchant FAQs

Why 72 hours and not 24? A single day of zero conversions is often noise: a slow weekday, a small ad set, or a conversion that lands just after the window. Three consecutive days of zero-conversion spend is a pattern worth acting on. The 72-hour window trades a little detection speed for far fewer false fires. Is zero-conversion spend always wasted? Not always. Some of it is unmeasured conversion, where the Pixel or Conversions API failed to capture an iOS purchase. Always check CAPI/Pixel Tracking Broken before pausing. A small amount of zero-conversion spend is also normal for new ad sets in the learning phase; the floor is there to suppress that. How do I tell a broken creative from a fatigued one? Look at the history. An ad set that never converted from launch usually has a broken or mis-targeted destination link. An ad set that converted recently and then stopped is fatiguing; CTR Trend will usually show the decline leading into the burst. Why does the test ad set not fire even though it has zero conversions? Its spend is below the configured floor. Tiny test budgets routinely run a few days without a conversion, so the floor suppresses them. Adjust the floor in the Alert Rules tab to match what counts as material spend for your account. Should I let Vortex IQ auto-pause these? Auto-pause can be enabled for high-spend bursts, but most teams prefer a manual review because a tracking break can masquerade as wasted spend. The conservative default is to surface the recommendation and let a human confirm before pausing. Why did the figure change after I read it this morning? Conversions ingest with a lag and modeled conversions can attach after the fact. An ad set that looked fully wasted at 09:00 may show a few late-attributed conversions by midday. Trust the figure once the window has settled rather than acting on the freshest hour.
