Tracked live in Vortex IQ Nerve Centre. How to read it, why it matters, and how to act on it. **Metrics type:** [Key Metrics](/nerve-centre/overview#metrics-types-explained) • **Category:** [Ad Platform](/nerve-centre/connectors#connectors-by-type) ## At a glance > Spend on Pinterest keywords or interest targeting that produced **zero conversions** in the 30-day window AND have had at least 7 days of serving (giving Pinterest's 30-day attribution tail a chance to start). Sums dollars on these "dead" terms. The most common single quick-win lever for ROAS on Pinterest, but with a caveat: Pinterest's long attribution window means a "wasted" keyword today may still earn engagement-attributed revenue in 30+ days. Be patient before pruning. | | | | -------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **What it counts** | `SUM(spend)` over keywords/interests where `conversions = 0` AND `keyword.first_serve_date < (today - 7 days)` AND `keyword.status = ACTIVE`. Account currency, after micros conversion. | | **API endpoint** | `POST /v5/ad_accounts/{id}/reports`, `level: KEYWORD` and `level: INTEREST` > `metrics: SPEND_IN_DOLLAR_MICRO`, `TOTAL_CHECKOUT`, `TOTAL_CHECKOUT_VALUE_IN_DOLLAR`. Filter to zero-conversion rows on the engine side. | | **Ad-format scope** | All paid Pinterest formats with keyword or interest targeting (Standard Pin, Shopping, Carousel). Idea Pin video uses interest targeting; Shopping uses both keyword and product-feed-driven targeting. | | **Cost basis** | Whatever the parent campaign bids on (CPC / CPM / oCPM). The card sums dollars regardless. | | **Conversion attribution** | **30-day click + 30-day engagement** default. The 7-day "settle" filter is intentional: many "zero-conversion" keywords on day 5 will earn an engagement-attributed conversion by day 25. Without the 7-day filter, this card would massively overestimate waste. | | **Engagement vs click** | A keyword can have many saves but zero conversions; that's not waste, it's planning-phase awareness. The card uses combined `TOTAL_CHECKOUT` (click + engagement) as the conversion definition to avoid mistaking save-rich-but-not-yet-converting Pins for waste. | | **Audience skew context** | Wasted spend on Pinterest reads heavier on poor-audience-fit verticals (B2B SaaS, mens-only, industrial) where many keywords genuinely never convert. On well-fit verticals (decor, fashion, wedding), wasted-spend > 5% of total spend usually means keyword bloat from over-targeting, prune the long tail. | | **Currency** | Account base currency, single per ad account. | | **Bot / invalid traffic** | Pinterest's IVT clawback reduces wasted-spend retroactively (a bot click cost refunded means the spend on that keyword drops 7-14 days later). The card refreshes on Pinterest's revisions. | | **Time window** | `30D` (last 30 days; the 7-day settle filter is internal to the calculation). | | **Alert trigger** | `> $0` on any keyword that's been active for at least 7 days. The threshold is intentionally aggressive because waste compounds: if you have £200 of waste this month, that's £2,400 a year. | | **Roles** | owner, marketing, finance | ## Calculation Calculated automatically from your Pinterest 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 home decor brand running Pinterest Shopping with broad keyword + interest targeting. Account currency: GBP. The 30-day window covers 02 Apr 26 to 01 May 26. | Keyword / interest | Days active | Spend (30D) | Saves | Clicks | Conversions | Status | | ----------------------------- | ----------- | ----------- | ------ | ------ | ----------- | ----------------------------------------------- | | `living room decor` (kw) | 30 | £820 | 4,200 | 1,840 | 38 | Performing | | `farmhouse style` (kw) | 30 | £640 | 3,800 | 1,420 | 24 | Performing | | `bedroom design` (interest) | 30 | £580 | 2,400 | 980 | 16 | Performing | | `cottagecore aesthetic` (kw) | 22 | £180 | 2,100 | 480 | **0** | **Wasted (interest, no convs)** | | `boho wall art` (kw) | 30 | £140 | 920 | 240 | **0** | **Wasted** | | `wedding centerpiece` (kw) | 18 | £120 | 1,400 | 320 | **0** | **Wasted** (poor product-fit) | | `kitchen renovation` (kw) | 12 | £80 | 480 | 110 | **0** | **Wasted** (planning-time, no immediate intent) | | `mens room ideas` (kw) | 24 | £45 | 80 | 18 | **0** | **Wasted** (audience mismatch) | | **Total wasted** (5 keywords) | - | **£565** | 4,980 | 1,168 | **0** | - | | **Total spend (this period)** | - | **£12,000** | 70,600 | 13,560 | 566 | - | | **Wasted as % of total** | - | **4.7%** | - | - | - | - | What's interesting: 1. **£565 (4.7%) is wasted spend.** That's middle-of-the-pack for a fashion/decor brand. Under 3% is excellent; 5-10% is typical; over 10% means you have keyword/interest bloat. Annualised, this £565 is roughly £6,800 you could redirect to performing keywords. 2. **`cottagecore aesthetic` has 2,100 saves and 480 clicks but zero conversions.** That's the trickiest category, lots of *interest* but no *purchase*. Three possible reasons: (a) the audience is researching / planning (cottagecore is a long-cycle aesthetic), (b) your products don't actually match the aesthetic (your "cottage-themed" range may be too modern for the audience expecting truly rustic), (c) the landing page is wrong for the saver intent. Don't immediately pause; **let it run another 14 days** so the engagement window can credit any late conversions, then if still zero, prune. 3. **`wedding centerpiece` shows 1,400 saves but 0 conversions** because this brand sells home decor, not wedding-specific products. Pinterest's broad-match grabbed the keyword but the audience-product fit is wrong. Pause immediately; this one won't recover. 4. **`mens room ideas` is the audience-mismatch tell.** Pinterest's audience is \~60% female and decor-skewing-feminine; mens-room-themed keywords on a fashion-forward decor brand earn poor engagement (only 80 saves) and zero conversions. **Pause immediately; no amount of waiting fixes audience mismatch.** 5. **The 7-day settle filter is doing real work here.** Two more keywords (`scandinavian living room` and `botanical prints`) earned their first conversion on day 8 and day 11; without the filter, they would have been flagged "wasted" on day 5 and prematurely paused. **Patience matters on Pinterest.** Other ad platforms (Google, Meta) can be pruned within 3-5 days; Pinterest needs 7-14. Quick sanity tests: * Wasted \< 3% = lean keyword set, good discipline. * Wasted 3-7% = normal; review monthly. * Wasted 7-15% = bloat; do a quarterly prune of all zero-conversion keywords with > £50 spent. * Wasted > 15% = either audience-mismatch problem (wrong vertical) or broken Pinterest Tag (no conversions counted, which makes everything look wasted). * Saves high + conversions zero on a single keyword = wait 14 more days before pruning. * Saves low + conversions zero + > 7 days old = prune immediately, audience mismatch. ## Sibling cards merchants should reference together | Card | Why pair it with Pinterest Wasted Spend | | ---------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------- | | [Pinterest Total Spend](/nerve-centre/kpi-cards/pinterest-ads/total-spend) | The total. Wasted ÷ Total = waste percentage. Watch the ratio; absolute waste rises with budget growth even when efficiency is unchanged. | | [Pinterest Zero-Conversion Spend](/nerve-centre/kpi-cards/pinterest-ads/zero-conversion-spend) | The campaign-level companion. Wasted Spend is keyword-level; Zero-Conversion is whole-campaign. Read together to find the diagnosis layer. | | [Pinterest Top Keywords by Spend](/nerve-centre/kpi-cards/pinterest-ads/top-keywords-by-spend) | Inverse view: where money is going *and* converting. Compare against this card to ensure spend concentration matches conversion concentration. | | [Pinterest Top Keywords by Conversions](/nerve-centre/kpi-cards/pinterest-ads/top-keywords-by-conversions) | The performers. Use to identify keywords worth doubling spend on after pruning waste. | | [Pinterest Search Terms Report](/nerve-centre/kpi-cards/pinterest-ads/search-terms-report) | Search-term-level detail, useful when broad-match keywords are wasting spend on irrelevant queries. Add negatives based on this report. | | [Pinterest Conversion Lag](/nerve-centre/kpi-cards/pinterest-ads/conversion-lag) | Companion sanity check. If conversion lag is unusually long, "wasted" keywords may just be late-attributing. Wait before pruning if lag is climbing. | | [Pinterest ROAS](/nerve-centre/kpi-cards/pinterest-ads/roas) | The bottom-line lever. Pruning £500 of wasted spend without losing revenue lifts ROAS proportionally. | | [Google Ads Wasted Spend](/nerve-centre/kpi-cards/google-ads/wasted-spend) | Peer ad-platform metric. Same idea, different attribution mechanics. Useful for cross-platform waste audits. | ## Reconciling against the vendor's own dashboard **Where to look in Pinterest Ads Manager:** [Pinterest Ads Manager > Reporting > Performance > Keyword/Interest level](https://ads.pinterest.com/advertiser/reporting/performance/) > group by Keyword > columns: `Spend`, `Total checkout` (or your conversion goal). Sort by Spend descending and filter to "Total checkout = 0" rows. The list of keywords is the same set this card sums, with one difference: Pinterest's UI does not have the 7-day settle filter, so it will show MORE rows than this card (including freshly launched keywords still in their attribution-window grace period). **Why our number may legitimately differ from Pinterest's UI:** | Reason | Direction | Why | | ------------------------------------------ | ----------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **7-day settle filter** | Ours lower | We exclude keywords active \< 7 days because Pinterest's 30-day attribution tail means many of them will earn their first conversion on day 8-14. Pinterest's UI counts them as zero-conversion immediately. The settle filter is the right behaviour for an alerting card. | | **Time zone**, account TZ vs UTC | Boundary days off | Pinterest reports in the ad account's TZ; this card uses UTC. Affects the "today" cohort of keywords; the 30-day window is largely insensitive. | | **Long attribution window backfill** | Ours lower over time | A keyword that reads "wasted" today will quietly drop off this card if a conversion lands within the 30-day engagement tail. The Pinterest UI shows the same self-correcting behaviour. **Don't act on this card the same day; wait 7 days for stability.** | | **Engagement vs click reporting variance** | Either | If the attribution selector in Pinterest's UI is set to "click only", more keywords will appear wasted (engagement-attributed conversions get hidden). This card uses the account default (combined click + engagement), the more honest read. | | **API rate limits and ingest lag** | Ours lower for last 4-6 hours | Async report API, refresh \~4 hours. The Pinterest UI is closer to real-time. | **Cross-connector reconciliation:** This is a Pinterest-only metric. There's no direct counterpart on commerce platforms (Shopify doesn't have a "wasted spend" concept since it doesn't run ads). The closest cross-connector reads are peer ad platforms: | Card | Expected relationship | What causes legitimate divergence | | -------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------- | | [`google_ads.gads_wasted_spend`](/nerve-centre/kpi-cards/google-ads/wasted-spend) | Peer waste read. Different attribution mechanics. | Google Ads typically reads higher waste because its 7-day click + 1-day view window is shorter, fewer late-attribution conversions to "rescue" keywords. | | [`facebook.meta_ads_wasted_spend`](/nerve-centre/facebook/meta_ads_wasted_spend) | Peer. | Meta's 7d-click + 1d-view; similar caveat to Google. | | [`shopify.total_revenue` filtered to Pinterest UTM](/nerve-centre/kpi-cards/shopify/total-revenue) | If Pinterest "wasted" keywords show commerce-platform Pinterest-tagged revenue, the Pinterest Tag is missing conversions. **Check Pinterest Tag health if any "wasted" keyword has substantial UTM revenue.** | Tag misconfiguration, server-side redirect dropping the click ID, ad-blocker rates above platform average. | ***
Documentation cross-reference (for agencies running multiple ad platforms) Wasted Spend is defined per-platform with platform-specific settle filters because of differing attribution mechanics. **Do not naively compare wasted-spend percentages across Pinterest, Google, and Meta** without normalising the settle filter. A "5% waste on Pinterest" is roughly equivalent to "2-3% waste on Google" once you account for Pinterest's longer attribution tail (which mechanically reduces same-period waste). * [`google_ads.gads_wasted_spend`](/nerve-centre/kpi-cards/google-ads/wasted-spend), 7-day settle filter * [`facebook.meta_ads_wasted_spend`](/nerve-centre/facebook/meta_ads_wasted_spend), 7-day settle filter * [`pin_wasted_spend` (this card)](/nerve-centre/kpi-cards/pinterest-ads/wasted-spend), 7-day settle filter (could arguably be 14-day given the longer engagement tail)
## Known limitations / merchant FAQs **Should I immediately pause every keyword on the wasted-spend list?** **No, not on Pinterest.** The 30-day click + 30-day engagement attribution window means many "wasted" keywords have saves piling up that will convert weeks later. The 7-day settle filter on this card already excludes the freshest keywords, but you should still wait 14 days from the alert before pausing if the keyword has > 100 saves. If saves are also low (\< 50 in 14 days), pause immediately, that's audience mismatch, not slow attribution. **Is my Pinterest Tag broken if everything reads as wasted?** Possibly. If wasted spend is over 30% of total spend, check: (1) Is the Pinterest Tag firing on your purchase confirmation page? Use the Pinterest Tag Helper Chrome extension to verify. (2) Is the Tag configured to send `purchase_value`? If only `purchase` events are sent, conversions count but ROAS appears as zero. (3) Has there been a recent site re-platform? A migration from Shopify > BigCommerce often breaks the Tag. (4) Is your tracking blocked by Consent Mode v2 or ad-blocker proportion above 30% of traffic? Pinterest does not yet have full Consent Mode integration, so high-ad-blocker audiences naturally read more "wasted". **Why does Pinterest read 5% wasted while Google reads 2% wasted on the same brand?** Pinterest is a *decision-time* channel, so genuine waste there overlaps with "audiences not yet ready to buy". Google's intent-time queries either convert quickly or genuinely waste. The honest comparison is over a 90-day window, not 30; over 90 days, Pinterest waste typically converges on the Google number because the engagement tail finishes attributing. **What's the cost of a £100 wasted-spend keyword if I leave it running?** £100 in the current 30-day window plus probably £100/month going forward, around £1,200/year per keyword. The cost compounds because Pinterest's algorithm rebalances impressions toward keywords that are serving even when they're zero-converting (the algorithm sees "spend = good" without conversion context). Pruning aggressively prevents the algorithm from spending more on dead terms. **My wasted spend went from 4% to 12% this week, what happened?** Most likely causes, in order: (1) **Pinterest Tag broke**, conversions stopped counting, all keywords appear wasted. Check Pinterest Tag Helper. (2) **Audience saturation**, you've exhausted the high-converting cohorts and are now into less-engaged ones. Check [Pinterest CTR Trend](/nerve-centre/kpi-cards/pinterest-ads/ctr-trend) for a CTR drop. (3) **New campaign launch**, freshly launched keywords are pre-7-day-settle but somehow appearing on the list (rare, indicates settle-filter bug). (4) **Seasonal mismatch**, summer fashion keywords running into autumn season; the audience moved on but the keywords didn't. **Is wasted spend on Idea Pin (video) measured differently?** Slightly. Idea Pin uses interest targeting, not keyword. The card sums interest-level spend on interest cohorts with zero conversions in 30 days. The 7-day settle still applies. Idea Pin is more often "wasted" by definition because it's an awareness format; expect 8-15% of Idea Pin spend to read wasted on average. Don't pause on this card alone for Idea Pin; check engagement-per-dollar and 60-day-trailing ROAS instead. **Does this card include keywords I've manually paused?** No. Only `status = ACTIVE` keywords with > 0 spend in the window. Paused keywords stop appearing the day they're paused. If you pause a wasted keyword today, it disappears from this card tomorrow but the dollars already spent stay in [Pinterest Total Spend](/nerve-centre/kpi-cards/pinterest-ads/total-spend). **Should I rebuild keyword lists from scratch quarterly?** On Pinterest, **yes more often than other platforms**. Pinterest's algorithm benefits from keyword/interest evolution; stale lists stop performing as the audience taste shifts (especially in fashion, decor, wedding). A quarterly review where you prune all zero-conversion keywords and add 5-10 new ones based on [Search Terms Report](/nerve-centre/kpi-cards/pinterest-ads/search-terms-report) findings is healthy. Annual reviews are too slow for trend-driven verticals. **Multi-account aggregation, how does waste roll up?** The card aggregates across same-currency child accounts in the same Pinterest Business Manager. Mixed-currency setups need per-account treatment. The 7-day settle filter is applied per keyword, not per account. *** ### Tracked live in Vortex IQ Nerve Centre *Wasted Spend* is one of hundreds of KPI pulses Vortex IQ tracks across Pinterest Ads and 70+ other ecommerce connectors.
