Optimization and Performance Management
The optimization loop
Optimization is continuous: monitor delivery, diagnose underperformance, adjust bids/budgets/targeting/creative, and re-measure. Levers include bid strategy changes, audience refinement (add high-performing segments, exclude poor ones), frequency cap tuning, dayparting, supply-source and deal adjustments, and creative rotation.
Diagnosing problems
Common issues: under-delivery (bid too low, audience too narrow, creative rejected, budget exhausted), over-frequency (cap too loose), and high CPA (weak audience or creative). Use reporting to isolate the dimension - audience, creative, supply, or device - before changing bids.
Traps
- Changing multiple variables at once, making results unreadable.
- Raising bids to fix a problem that is actually creative rejection or narrow audience.
- Ignoring frequency when reach saturates.
- Judging CTV or upper-funnel campaigns on last-click CPA alone.
Rule of thumb
Change one lever at a time, give it enough data to be meaningful, and compare against a baseline. If delivery is low, check creative approval and audience size before touching bids. If CPA is high but delivery is strong, refine audience and creative rather than cutting budget.
