At a glance

Sum of spend on StackAdapt campaigns that recorded zero conversions across the entire window. Campaign-level twin of Wasted Spend (which is placement-level). A whole campaign with zero conversions is a bigger problem than a bad placement; it usually means goal, audience, pixel, or creative are fundamentally misaligned. Excludes campaigns younger than 7 days to avoid penalising still-learning BidCore runs.

Calculation

Calculated automatically from your StackAdapt data. See the At a glance summary above for what the metric tracks and the worked example below for a typical reading.

Worked example

The same US homeware brand. Window 02 Apr 26 to 01 May 26. What’s interesting:
  1. CTV “Outdoor Living” test ($1,400) is the bigger problem. 18 days, no conversions on a CTV view-through campaign suggests one of: (a) view-through window set to 1-day instead of 7 (a classic config error on test campaigns); (b) the conversion pixel isn’t tracking the right event; (c) the audience targeting is genuinely wrong. Action: check view-through window first (5-minute fix), then pixel config, then audience. Pause as last resort.
  2. Programmatic Audio test ($620) at 14 days zero-conv is borderline. Audio is structurally hard to attribute (no clicks; the user heard the ad while driving and bought a week later via Branded Search). The campaign may be working but credit is going to other channels. Action: check if Branded Search volumes ramped during the audio campaign window; if yes, the campaign is incremental despite zero StackAdapt-attributed conversions; classify as awareness and continue. If no, pause.
  3. The new Display Test (4 days old) is excluded by design. BidCore needs 7+ days to exit learning phase; flagging earlier creates noise.
  4. 4.6% zero-conv spend is on the borderline of healthy. Healthy DSP runs 2, 5%; 4.6% is at the upper end. Fixing the CTV view-through config alone would drop it to 1.4%, well within healthy.
  5. Don’t confuse this card with Wasted Spend. That one is placement-level; this one is campaign-level. The two should be read together: a healthy campaign can have wasted placements; a zero-conv campaign has structural issues.
Quick sanity tests:
  • One campaign zero-conv with high impressions = pixel/goal misconfig OR audience mismatch.
  • Multiple campaigns zero-conv simultaneously = global tracking outage; check pixel sitewide.
  • CTV campaign zero-conv = check view-through window first (1d vs 7d) before anything else.
  • Audio campaign zero-conv with rising Branded Search = working but incremental, not direct.
  • Zero-conv campaign older than 30 days = past learning, no signal; pause and restructure.

Reconciling against the vendor’s own dashboard

Where to look in StackAdapt: StackAdapt → Reports → Campaigns, sort by Conversions ascending. Campaigns with zero conversions and >7 days of activity are the action set. StackAdapt does not surface “zero-conversion spend” as a single number; this card derives it. Why our number may legitimately differ from a manual cut: Cross-connector reconciliation:

Known limitations / merchant FAQs

Should I just pause every zero-conversion campaign? No. Diagnose first. Order of checks: (1) Is it CTV? Check view-through window; should be 7d for CTV-heavy. (2) Check the pixel: is the conversion event firing on the order-confirmation page? (3) Check the audience: are clicks/impressions reasonable? Low click volume = audience too narrow or bid too low. (4) Check the creative: is it serving correctly? Sometimes creative is disapproved silently. Pause only after these checks fail. A campaign has been zero-conv for 30 days, what now? Pause. After 30 days with 7+ days of activity and zero conversions, the campaign has had every chance. Pause, restructure (new audience, new creative, new landing page, possibly new conversion goal), and relaunch as a fresh campaign rather than reactivating (BidCore retains learning state and won’t re-explore). Why does this card exclude campaigns under 7 days? BidCore’s learning phase needs 50, 100 conversions to stabilise; for a fresh campaign, 7 days is the minimum window where zero-conversions becomes diagnostic. My CTV campaign shows zero conversions but I see Branded Search ramping during the campaign window, what’s happening? The classic CTV incrementality signal. CTV viewers don’t click TVs; they later go to Google and search your brand name (now Branded Search), then buy. Your CTV is working but credit is going to Search. This is not a problem with the campaign; it’s a measurement limitation. Use incrementality testing (CTV holdout in one geo) to prove the lift, then accept that StackAdapt-attributed conversions will under-state CTV’s value. My audio campaign shows zero conversions, is it broken? Probably not, but it’s hard to tell. Audio attribution is the hardest in DSP; clicks are rare and view-through doesn’t really exist for audio. Look for: (a) Branded Search lift during/after audio flight; (b) Direct traffic increase; (c) increase in Email subscribers if the audio CTA is “subscribe to our newsletter”. If none of these, pause; the campaign isn’t working. The same campaign has high clicks and zero conversions, what’s most likely? In order: (1) Pixel not configured for purchases. Campaign goal in StackAdapt is “Awareness” or “Engagement”, so the conversion pixel never fires. (2) Pixel fires the wrong event. It’s tracking page-views or add-to-cart instead of purchase. (3) Landing page broken. Users click, land, bounce immediately; check load time and form completion. (4) Audience genuinely doesn’t convert. Less common; if the previous three are clean, the audience-product fit is wrong. Can I trust the figure for “today” or “this week”? Use 30-day for action. 7-day is too noisy on DSP because of view-through lag (especially CTV). The 30-day figure is the actionable read. Why doesn’t StackAdapt auto-pause zero-conversion campaigns? Because zero-conv on a 14-day window is sometimes false (long-tail conversions not yet surfaced, especially CTV). Auto-pausing would kill campaigns that would have converted on day 18, 22. The platform errs toward letting BidCore explore; the human judgement (this card surfaces candidates) is the corrective. **My retargeting campaign shows zero-conv but the spend is only 200,shouldIworry?∗∗Less.Small−spendcampaignsproducesmallsamples;zero−convon200, should I worry?** Less. Small-spend campaigns produce small samples; zero-conv on 200 spend is statistical noise (20, 40 clicks isn’t enough to expect conversions). Worry about zero-conv at $1,000+ spend.
