At a glance

Gross media spend on StackAdapt, the self-serve programmatic DSP for mid-market advertisers. Sums spend across all campaigns in the window. StackAdapt is multi-channel (display, native, CTV, video, audio, in-game, DOOH); this card aggregates regardless of channel. The platform’s edge is its AI bidding (“BidCore”); on a properly-fed campaign it typically delivers 20, 40% better CPC than manual bidding within 14 days.

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

A US homeware brand running StackAdapt as part of a mid-market omni-channel programmatic strategy. The 30-day window is 02 Apr 26 to 01 May 26. What’s interesting:

1. CTV is 41% of spend at $18,200 but contributes zero clicks (no click events on a TV). View-through attribution is doing the heavy lifting; if your CTV view-through window is set too short (default 1 day vs the 3, 7 day reality), you’ll under-credit CTV and over-credit display. Action: extend CTV view-through to 7 days for honest reads.
2. **CTV CPM at $13.00 is mid-market**; premium publisher CTV (NBC, CBS via direct deals) runs$25, 45 CPM. StackAdapt routes through Magnite, Pubmatic, OpenX, etc., for cheaper CTV inventory at slightly lower premium-publisher quality. The trade-off is appropriate for mid-market budgets.
3. **Display at $2.95 CPM is healthy**; programmatic display floors are$1.50, 2.00 for low-quality remnant; $5+ is brand-safe premium.$2.95 is the BidCore sweet spot, brand-safe inventory with efficient targeting.
4. **The Native CPC of $0.75 (5,400 ÷ 7,200)** is competitive vs Taboola direct ($0.30, 0.40 typical), but StackAdapt’s audience targeting allows tighter prospecting that compensates.
5. The 30-day prior window had spend $36,500 on the same channel mix; 21% rise this window. BidCore exited learning phase on the Display Prospecting campaign on 11 Apr 26 and drove most of the increase. ROAS held flat, so the rise is healthy scaling, not waste.
6. **Audio at $3,200 is small but worth watching**; podcast/Spotify sponsorship CPM benchmarks are$15, 25 typical, so $4 CPM here is suspiciously low quality (likely run-of-network audio fill). Check creative placements before scaling.

Quick sanity tests:

• Spend up + impressions up + CPM stable = healthy volume scaling, BidCore working.
• Spend up + CPM up = bidding into more expensive inventory; check if it’s BidCore exploring premium publishers.
• Spend up + CPM down + clicks down = inventory degrading; auto-bid won the auction race-to-the-bottom; raise CPM floor.
• Spend flat + CTV CPM rising = peak hours pressure (Q4 / sports finals / awards season).
• Spend down sharply + impressions down sharply = BidCore is failing to find inventory at your bid; raise CPM or expand audience.

Reconciling against the vendor’s own dashboard

Where to look in StackAdapt: StackAdapt → Reports → Campaigns → “Spend” column at the account level for the same date range. The footer total should match this card to within sub-percent rounding once ingest catches up (allow 1, 2 hours for “today”). Other StackAdapt views that look similar but are not the same number:

• Reports → Channels: spend per channel (display, native, CTV, etc.). Sum across channels matches account spend.
• Reports → Creative: spend per creative. Same total, different cut.
• Working Media: gross spend minus the StackAdapt platform fee. NOT what this card uses; this card uses gross.

Known limitations / merchant FAQs

My StackAdapt spend just spiked, what happened? The most common cause is BidCore (StackAdapt’s AI bidding) exiting the learning phase. BidCore typically holds delivery low for the first 50, 100 conversions; once it has signal, it ramps to maximise volume at the target CPA. Check Spend by Campaign for a single-campaign jump. Other causes (in order): (1) CTV inventory hitting peak hours (evening prime); (2) seasonal CPM rise in Q4 / sports finals / awards season; (3) a manual budget increase that nobody flagged. StackAdapt vs The Trade Desk, when do I pick which? StackAdapt is mid-market self-serve ($5k, 50k/month sweet spot), with stronger native and audio integrations and easier UI for in-house teams. The Trade Desk is **enterprise** ($50k, 500k+/month sweet spot), used by large agencies and direct enterprise teams, with deeper CTV inventory deals and more sophisticated audience tooling. Run StackAdapt if your team manages programmatic in-house and budgets are mid-market; run TTD if you have agency support and need premium CTV inventory or a global footprint. Why is CTV CPM so much higher than display CPM? CTV is premium inventory. A 30-second video on a logged-in TV in someone’s living room captures attention in a way a banner ad never does, and the inventory is scarce (a TV plays one ad at a time). Premium CTV runs $25, 45 CPM; mid-market via DSPs like StackAdapt runs$10, 20 CPM. The CPM premium is real, the attention is real; the attribution is the problem (no click events, view-through only). My CTV campaign reports zero clicks, is something broken? No. CTV impressions cannot generate clicks; you cannot tap a TV. CTV is measured purely on view-through conversions. Make sure your view-through window is 3, 7 days (not the default 1 day) for CTV-heavy campaigns; 1 day under-credits CTV by 60, 80%. What does “BidCore” actually do? BidCore is StackAdapt’s machine-learning bidder. It evaluates each impression in real time across multiple signals (user, context, time-of-day, recency, audience match) and bids accordingly. Compared to manual CPM bidding, BidCore typically delivers 20, 40% better CPC after a 14-day learning period. The catch: it needs sufficient conversion volume to learn. Campaigns with <30 conversions/week struggle on BidCore; manual bidding is more reliable below that volume. Why does my GA4 show fewer StackAdapt sessions than StackAdapt reports clicks? Three structural reasons: (1) ad-blocker leakage (5, 10%); (2) bounces before GA4 fire (3, 7%); (3) CTV impressions that the user later searched/typed for the URL (now Direct in GA4, not StackAdapt). Expect 85, 95% reconciliation between StackAdapt clicks and GA4 stackadapt-source sessions. Below 80% suggests broken UTM tagging on the click-out URLs. Can I trust the “today” spend figure? Less than rolling 7-day. Today’s spend reads from incomplete intra-day ingest; allow until tomorrow’s first sync for the stable figure. What’s the platform fee structure on StackAdapt? StackAdapt charges a percentage of working media, typically 15, 25% for mid-market accounts (lower for high-volume direct accounts). The fee is included in the gross spend this card reports. Working Media (gross minus fee) is available as a separate StackAdapt UI toggle but not the default view. My ROAS is fine but my reach is low, what should I do? Increase the CPM ceiling on BidCore. The algorithm caps bids at the configured ceiling; if it’s too tight, you win the inventory you can afford but miss the broader reach. Alternatively, expand audience targeting (broader geos, broader interest segments) to give BidCore more inventory to choose from.
