Direct Question Targets
Frequently Answered Questions
CPM vs CPI vs CPA: which should I choose for my campaign?
Quick Answer: Choose CPM for volume and top-of-funnel reach, CPI for app user acquisition with predictable install costs, and CPA when you have sufficient event volume (>50/day) and verified postbacks for deep in-app actions.
How does bid shading work, and why does it lower what I pay?
Quick Answer: Bid shading estimates the lowest bid needed to win a first-price auction by analyzing historical clearing prices, reducing media cost below your max valuation while preserving win rate.
Why is my CPA rising, and what should I check first?
Quick Answer: Check your conversion postback latency first, then review creative fatigue (frequency > 4), publisher placement concentration, and recent bid floor adjustments on your top SSPs.
What is a postback, and how do I set one up for my campaign?
Quick Answer: A postback is an automated server-to-server HTTP call sent by an attribution provider to a DSP confirming a user action (install, purchase) with matching click identifier tokens.
What happens when conversion postbacks are delayed? How can bidding still optimize?
Quick Answer: Delayed postbacks cause naive engines to undervalue slow-converting inventory. Advanced engines model conversion arrival lag curves to maintain appropriate bids during the maturation window.
How long does a programmatic campaign take to learn, and why does it need data first?
Quick Answer: A bidding engine typically requires 3 to 7 days and at least 50–100 conversion events to establish statistical confidence across contextual dimensions before aggressive optimization begins.
How do I evaluate a DSP before committing budget?
Quick Answer: Evaluate DSPs on 5 criteria: fee transparency (no hidden markups), algorithmic control (human rules vs black box), raw log-level access, pre-bid fraud filtering, and verifiable MMP integrations.
Click-through vs view-through attribution: what's the difference and which counts?
Quick Answer: Click-through attribution credits conversions to the last clicked ad; view-through credits conversions when an ad was only displayed. Keep them separate to avoid overpaying for passive view impressions.
How do rules and constraints change what a bidding engine does?
Quick Answer: Rules act as deterministic boundaries on probabilistic models, preventing algorithms from overbidding, exceeding CPA ceilings, or running on non-performing hours regardless of statistical predictions.
