At a glance
Sum of spend on Taboola campaigns that recorded zero conversions across the entire window. The campaign-level twin of Wasted Spend (which is publisher-level). A whole campaign with no conversions is a bigger problem than a single bad publisher; it usually means the campaign goal, audience, or creative is fundamentally misaligned with native inventory. Excludes campaigns younger than 7 days to avoid penalising still-learning smartBid runs.
| What it counts | Spend (account currency) summed across campaigns where conversions = 0 AND clicks > 0 AND campaign_age >= 7 days over the 30-day window. |
| Cost basis | Whatever the campaign was bidding on (CPC, CPM, smartBid CPA). |
| Currency | Account currency. |
| Conversion attribution | Click-through, last-click within Taboola’s window. A campaign that drove clicks which converted via another paid channel is counted as zero-conversion (Taboola did not get the credit). |
| Attribution window | 30-day click default (configurable 1, 30 days). On a 7-day window, more campaigns appear “zero-conversion” simply because the long-tail conversions have not yet posted; this card uses 30D for that reason. |
| Bot / invalid traffic | IVT-filtered before billing. |
| Time window | 30D. Campaigns younger than 7 days are excluded. |
| Alert trigger | >$0 on any campaign >7D old. Practical action threshold: any campaign with >£500 spent and zero conversions across 7+ days should be paused or fundamentally restructured. |
| Roles | owner, marketing, finance |

| Article Distribution | 142 | 4,200 | 18,400 | 142 | OK |

| Magnesium Newsletter Drop | 14 | 480 | 1,400 | 0 | ZERO-CONV ALERT |
| Probiotic Discovery (new) | 4 | 180 | 600 | 0 | Excluded (<7d age) |
| Total zero-conversion spend (this card) | £1,300 | 4,200 | 0 | 8.7% of total spend |
- The Vitamin D3 Awareness campaign is the bigger problem. £820 spent over 22 days with 2,800 clicks and zero conversions is a clear signal that something is wrong: the audience is right (people clicked) but the conversion tag did not fire. Most likely cause: the campaign is targeting an awareness goal in Backstage rather than conversions, so the Taboola pixel is not even configured to track purchases. Action: pause, switch goal to “conversions”, reconfigure pixel events, restart with smartBid CPA bidding.
- Magnesium Newsletter Drop (£480) is more borderline. 14 days is at the boundary of the alert threshold; native conversions can take 7, 14 days to surface. Wait until day 21, then act if still zero. The 1,400 clicks suggest the targeting works; the question is whether the landing page or pixel is breaking the conversion path.
- Probiotic Discovery (4 days old) is excluded by design. SmartBid’s learning phase is 50, 100 conversions; a 4-day-old campaign with 600 clicks is normal exploration. Do not flag as wasted; revisit at day 14.
- 8.7% zero-conversion spend is a yellow flag. Healthy native accounts run 3, 6%; this account has two distinct misconfigured campaigns. Fixing the Vitamin D3 pixel issue alone would drop the figure to 3.2%, well within healthy range.
- Don’t confuse this card with Wasted Spend. Wasted Spend is publisher-level (which sites within converting campaigns are wasting); this card is campaign-level (which whole campaigns are wasting). The two should be read together.
- One campaign zero-conv with high clicks = pixel or goal misconfiguration. Fix the campaign config first; do not pause.
- One campaign zero-conv with low clicks = audience too narrow or bid too low. Widen targeting or raise bid.
- Multiple campaigns zero-conv suddenly = global tracking outage. Check the pixel snippet across the site.
- Zero-conv campaign older than 30 days = pause or restructure. Past learning, no signal, no value.
- All campaigns under 7 days old = no data to act on; let the algorithm learn.
Sibling cards merchants should reference together
| Card | Why pair it with Zero-Conversion Spend |
|---|---|
| Taboola Wasted Spend | The publisher-level twin. This card identifies bad campaigns; that one identifies bad publishers within otherwise-good campaigns. Read together for the full picture. |
| Taboola Clicks vs Conversions | The pixel-health canary. If zero-conv campaigns have healthy click volumes, the issue is almost always a tracking or goal misconfiguration. |
| Taboola Total Spend | Context. £1,300 zero-conv on a £15k account is yellow; £1,300 on a £3k account is critical. |
| Taboola Conversions Trend | If account-level conversions are healthy but specific campaigns are zero-conv, the issue is campaign-config; if account-level conversions also dropped, suspect a global tracking outage. |
| Taboola Conversion Actions | What conversion events does the campaign expect? Sometimes a campaign is set up to track an event that the site does not fire. |
| Outbrain Zero-Conversion Spend | If the same merchant has zero-conv on both networks, the issue is almost certainly site-side (pixel, checkout, goal config), not network-specific. |
Reconciling against the vendor’s own dashboard
Where to look in Taboola Backstage: Backstage → Campaigns → Performance, sort the “Conversions” column ascending. Campaigns with zero conversions and >7 days of activity are the action set. Backstage does not surface “zero-conversion spend” as a single number; this card derives it. Why our number may legitimately differ from a manual Backstage cut:| Reason | Direction | Why |
|---|---|---|
| Time zone | Boundary days off | Backstage uses account time zone; this card uses UTC. Marginal at 30D. |
| Long-tail conversion lag | Card runs slightly high | A campaign labelled zero-conv today may pick up 1, 2 conversions in days 7, 14. The 7-day age threshold is designed to mitigate but not eliminate this. |
| Attribution window changes | Direction depends | Window changes reflow conversions retroactively. |
| Campaign age threshold | None | Both this card and any reasonable manual analyst cut would exclude <7-day-old campaigns. |
| Pixel vs CAPI dedup | Marginal | Taboola dedupes pixel and server-side events; both this card and Backstage UI reflect deduplicated counts. |
| Card | Expected relationship | What causes legitimate divergence |
|---|---|---|
outbrain.out_zero_conversion_spend | Independent. If both fire simultaneously, suspect a site-side issue (pixel, checkout, goal config). | Different network campaigns; usually independent unless the issue is site-side. |
google_analytics.ga_revenue_by_channel | Zero-conv campaigns should still show GA4 sessions if pixel fire is the issue (clicks land, GA4 fires, Taboola pixel does not). | Discrepancy here = pixel issue specifically; absent in GA4 = audience or landing page issue. |
shopify.total_revenue | Zero-conv on Taboola does not necessarily mean zero-revenue on Shopify; the conversions may have fired but credited to other channels. | Multi-touch attribution complicates the read. |
