Programmatic Ad Bidding and Budget Pacing Optimization
Optimizes online advertising auction performance by improving CTR prediction, real-time bid decisions, DSP campaign adjustments, budget allocation, and pacing controls, including incrementality-aware methods such as ghost bidding to better manage spend, delivery, and causal ROAS.
Business Blueprint
GROUNDEDAI optimizes programmatic ad bidding, pacing, campaign adjustments, and incrementality measurement so advertisers spend budgets more efficiently and know which ads truly drive sales.
The Problem
Advertisers and retail media operators need to improve auction performance, keep campaign spend on pace, reduce manual optimization work, and measure causal ROAS instead of relying only on legacy attribution or delayed conversion signals.
Advertisers / media buyers
They can make budget decisions from last-click or legacy attribution that credits purchases that would have happened anyway, while also facing manual work to act on campaign recommendations.
Campaign operations teams
They must monitor live campaigns, pacing, recommendations, and attribution delays without letting automation create overdelivery, underspend, or inconsistent optimization.
Retail media / ad platform operators
Poor pacing and attribution handling can cause unstable impression delivery, reduced revenue, blackout days, and unreliable reads on whether ads actually moved the needle.
Cost of Inaction
Poor budget pacing can result in unstable impression counts, reduced revenue, and blackout days; legacy attribution can keep budgets flowing to campaigns that are not truly incremental.
Process Fit
Campaign management & targetingAs-Is
Campaign teams set budgets, bids, frequency caps, targeting, and measurement plans, then manually monitor live delivery, recommendations, attribution, and pacing. Legacy attribution and delayed conversions can make it hard to know whether spend is efficient or whether the platform is overdelivering against budget goals.
To-Be
The ad platform uses live auction, campaign, spend, and conversion signals to recommend or execute campaign changes, dynamically adjust pacing controls, and run incrementality-aware measurement during live campaigns. Humans retain approval over strategy, budget guardrails, and measurement validity while routine optimization happens more consistently.

Systems Touched
Business Cycle
Upstream
- Campaign setup data must be available, including advertiser, order, line-item, targeting, bid, frequency, and optimization settings.
- Historical campaign spend and attribution patterns must be available to tune pacing start times and throttling behavior.
- Conversion and purchase tracking must cover in-scope users during the experiment, not only click- or view-attributed conversions.
Downstream
- Campaign changes can be retrieved as recommendations and adopted programmatically through API-driven actions.
- Budget pacing controls can dynamically update fast-finish timing and auction participation throttles based on campaign history.
- Budget decisions can shift from legacy attribution toward causal lift and incremental ROAS reads from live campaign experiments.
Value Evidence
- Causal iROASIMPROVED
iROAS performance ranged from 253% to 1,609% across advertisers-clear evidence that some programs are creating substantial value, while others have room to optimize.
- Incremental conversions per exposed userINCREASED
Incremental conversions per exposed user ranged from 4% to 29% -meaning up to 29 out of every 100 conversions among exposed users were truly incremental.
- iROAS impactIMPROVED
Early results show up to 15x iROAS impact To validate our ghost bidding methodology, we've conducted incrementality experiments with advertisers across multiple retail media platforms.

- Optimization frequency and consistency for large-scale campaignsIMPROVED

Risk & Governance
Delayed attribution can cause overspend after the daily spend goal is reached.
Posture: Use dynamic fast-finish timing and throttling based on historical campaign data, and validate changes with online budget-split experimentation and offline simulations.
Over-throttling can create consistent underspend, while small daily overdelivery can lead to end-of-period blackout days.
Posture: Govern pacing with explicit overspend and underspend guardrails, not a one-sided objective to eliminate spend risk.
Traditional fast-finish pacing can introduce severe overspend and sharp spend spikes.
Posture: Prefer gradual auction-participation throttling over abrupt end-of-period changes.
Incrementality results can be noisy or biased if the exposed and control populations are not cleanly defined.
Posture: Require clean population definitions, eligible-user controls, sufficient sample size, and adequate test duration before using results for budget decisions.
Attribution-only conversion counts can understate or distort causal impact.
Posture: Count all relevant conversions and purchases during the test period for in-scope users, not only click- or view-attributed conversions.
Operating Intelligence
How it works
AI runs the operating engine in real time.
Humans govern policy and overrides.
Measured outcomes feed the optimization loop.
Who is in control at each step
Each column marks the operating owner for that step. AI-led actions sit above the divider, human decisions and feedback loops sit below it.

Real-World Use Cases
RTBAgent LLM-based real-time bidding optimizer
An AI agent watches the ad auction market, looks at past bidding results and predicted click value, then adjusts how much to bid for ad impressions during the day.
DARA few-shot budget allocation for AI-generated bidding
An AI assistant helps an advertiser decide how to spend a limited ad budget across impression opportunities, even when the advertiser has only a small amount of past campaign data.
Smart Fast Finish daily ad-budget pacing
DoorDash changes when and how fast an ad campaign spends its remaining daily budget near the end of the day, based on that campaign’s past overspending behavior.
Feedback-control budget pacing for small-budget online advertising campaigns
The system watches how fast an ad campaign is spending money and automatically adjusts bidding pressure so the campaign spends its budget smoothly instead of too quickly or too slowly.
AI-native incrementality testing with ghost bidding for retail media ads
Moloco splits eligible shoppers into two similar groups. One group can see the retailer’s ad as usual; for the other group, Moloco checks when the ad would have won but quietly withholds it. Comparing purchases between the two groups shows how many sales the ad truly caused.
