At a glance

Total spend on entire campaigns that produced zero primary conversions in the window. The campaign-level analogue of Wasted Spend: if Wasted Spend hunts bad search terms inside healthy campaigns, this card hunts whole campaigns that are not earning their place.

Calculation

Calculated automatically from your Google Ads 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 fashion brand with £27,400 of total Google Ads spend over the 30-day window covering 14 Mar 26 to 12 Apr 26. The card flags £680 of spend across two zero-conversion campaigns. What a paid-acquisition lead does with this:
  1. The £680 (2.5% of total spend) is fully recoverable by pausing two ENABLED campaigns. Five-minute action.
  2. Display Remarketing zero-conversion is the awkward case. A small remarketing campaign (£420 / 30D) at zero conversions could be (a) genuinely unprofitable, (b) too small an audience to ever convert, or (c) driving view-through conversions invisible to this card. Cross-check All Conversions for the same campaign before pausing. If All Conversions also shows zero, pause immediately. If it shows 8-12 view-through, the campaign is doing brand-defence work and the £420/mo may be defensible.
  3. The “vintage 90s” test campaign is a textbook learning about test-budget hygiene. Set a £200 spend cap on test campaigns, auto-pause at zero conversions after that. Otherwise these creep along bleeding for months.
  4. Spend > £500 on a zero-conversion campaign is rarely OK. At that level you’ve given Smart Bidding enough volume to learn; if it cannot find a conversion, the campaign’s targeting or creative is broken, not under-optimised.
  5. Compare to last period. If this card was £200 last 30D and £680 this 30D, something new went wrong. If it has been £600-£700 every month for a year, you have a stable bleed pattern, sweep it monthly.
Quick sanity tests:
  • Card is zero: account is well-curated. (Or: every campaign got at least one conversion by chance.)
  • Card is > 5% of total spend: open it now, pause the worst offender.
  • A single campaign at > £1,000 zero-conversion: check if conversion tracking is broken on its landing pages first, before pausing. See Clicks vs Conversions.
  • New campaign in learning phase showing zero conversions on £100 spend: not in this card yet (probably), but track it. Set a £200 cap to auto-pause.
  • Card spikes during promo cycles: bargain-hunter clicks did not convert, expected, do not over-react.

Sibling cards merchants should reference together

​
Reconciling against the vendor’s own dashboard

Where to look in Google Ads UI: Google Ads > Campaigns, filter by Status = Enabled, sort Conversions ascending. Campaigns with Conv. = 0 and Cost > 0 in the date range are the rows this card sums. The total at the bottom should match this card to within 1-2%. Google Ads > Reports > Predefined > Performance > Campaign gives the same view in report form, useful for downloading the list. Other Google Ads views that look like the same number but aren’t:
  • Conv. = 0 with Status = Paused/Removed: not in this card. Past zero-conversion campaigns no longer running aren’t draining current budget.
  • All conv. = 0: a stricter filter. Some Display campaigns will pass the primary-conversions filter (zero) but fail the all-conversions filter (have view-through). Those are NOT in this card under primary-only logic.
  • Lost IS (rank/budget): a coverage problem, not a conversion problem.
  • Predefined > Account performance: account-rolled view; misses campaign-level breakdown.
Why our number may differ from Google Ads UI (rare): Why the BUSINESS metric often differs (the IMPORTANT one): A campaign marked here as “zero conversions” may have:
  • Driven conversions Google’s pixel missed. Tag-fire failures on specific landing pages cause pixel under-reporting. Cross-check against Clicks vs Conversions and the commerce platform’s UTM-tagged orders.
  • Driven offline conversions (phone, in-store) the merchant doesn’t import into Google Ads. Common for services/B2B, less common for ecom.
  • Driven multi-touch paths where Google Ads was an early click and got no last-click credit. The session value is captured by the closing channel. Cross-check with GA4 path analysis before pausing.
  • Driven conversions outside the attribution window. Default 7-day click window per conversion action; a high-consideration product (jewellery, furniture) may convert at day 14+ and never be attributed back.
  • Driven view-through assists that the primary-conversions filter excludes. For Display Remarketing especially, this can be material; check All Conversions for the campaign before pausing.

Known limitations / merchant FAQs

My zero-conversion spend is £0, is that good? It usually means every ENABLED campaign got at least one conversion in 30 days; that’s healthy. It can also mean you have very few campaigns running (no test campaigns, no Display, no Discovery), which may be over-cautious if you have growth headroom. A new campaign is in this card with £200 spend, do I pause it? Probably not yet. Smart Bidding needs 30-50 conversions to stabilise; pausing too early kills the test. Set a £500 spend cap and reassess at that point. If still zero conversions at £500, the test failed, pause. My Display Remarketing campaign is here, but I think it’s driving brand value, what now? Open All Conversions for the same campaign. If All Conversions > 0 (view-through assists), the campaign is doing brand-defence work and primary-only ROAS understates it. Decide based on the all-conversions read, not just this card. For most DTC brands, Display Remarketing is worth £200-£500/mo even at low primary-conversion rate; above that, scrutinise. My ROAS by Campaign is fine, but this card is £900, why? ROAS by Campaign only shows campaigns with conversions (you cannot compute ROAS on zero conversions, the denominator collapses). This card is the complement: campaigns excluded from ROAS rankings because they had zero. Always check both cards, the headline ROAS hides this £900 of bleed. My zero-conversion spend rose from £200 to £900 month-on-month, what happened? Three likely causes: (1) Conversion-tracking regression on specific campaigns. Check Clicks vs Conversions for those campaigns; if clicks held but conversions cratered, the tag broke. (2) You launched test campaigns that haven’t found product-market fit. Normal but should be capped. (3) Smart Bidding shifted spend into broader audiences after Performance Max changes; review PMax asset signals. Why is the threshold 500not500 not 0? Any non-zero spend is technically wasted, but pausing on £20 of zero-conversion campaign spend wastes more management time than it saves. The £500 threshold is a recoverability heuristic: at that level, a 5-minute pause action recovers more than the cost of the analyst’s time. Multi-currency setup, how does this card work? Google Ads accounts are single-currency. Multi-currency advertisers run separate accounts; this card is per-account, in account currency. The threshold is interpreted in account currency (£500 for GBP, €500 for EUR, $500 for USD). Can I trust the “today” zero-conversion spend? No. Today’s data is incomplete: most conversions take 1-4 hours to ingest, and some take much longer (cross-device, view-through windows). A campaign showing zero conversions today often picks up 2-3 conversions by tomorrow morning. Use the 30-day window, not today. My PMax campaign is in this card, can I pause individual placements? PMax has limited per-placement controls. Your levers: (1) tighten audience signals, (2) lower the budget cap, (3) account-level negative keywords (via Google Ads support). If a PMax campaign has £1,000+ spend and zero primary conversions over 30 days, the campaign’s signals or asset quality are wrong; rebuilding is usually faster than tuning. Why aren’t paused campaigns in this card? By design. Paused campaigns are not currently spending, so there’s nothing to recover by pausing them again. The card focuses on ENABLED campaigns where action recovers budget.
