Because placements need substantial data to make confident decisions, the optimization frequency should be much less aggressive than your regular keyword bid adjustments.
Once per month is the standard cadence for placement optimizations once your campaigns are dialed in.
Early on, you can optimize more frequently (every 2-3 weeks) while you're still establishing baseline performance and learning how your products perform across different placements.
Ad hoc adjustments are also appropriate when you notice significant performance shifts or during seasonal changes that impact placement performance differently.
Placements generally require 30-60 day date ranges to provide statistically confident data for optimization decisions. Unlike keyword optimizations, where you might use 7-14 day windows, placement data aggregates across many keywords, and you need sufficient volume to understand true performance patterns.
Optimizing placements falls into the macro change category of bid adjustments:
Longer timeframes for data confidence (30-60 days)
Modest adjustments (typically 10-15% changes)
Lower frequency (monthly rather than weekly)
Account-wide impact since placement adjustments affect all keywords in a campaign
Even if you're optimizing weekly with a 30-day lookback window, this is still a macro change because:
You're using a long timeframe for data
You're making broad adjustments that impact the entire campaign
You need high data confidence for placement decisions
