Seasonality adjustments are an advanced tool that can be used to inform Smart Bidding of expected changes in conversion rates for future events like promotions or sales.
Seasonality adjustments are currently available for Search, Shopping, and Display campaigns using Target ROAS and Target CPA bid strategies, as well as Smart Shopping and Performance Max campaigns using all bid strategies.
Note: Because Smart Bidding already manages seasonal events, only use seasonality adjustments if you expect major changes to conversion rates. Seasonal adjustments are ideal for short events of 1–7 days. They may not work as well if you use them for extended periods (more than 14 days at a time). Seasonality adjustments are currently available for Search, Shopping, Display, and Performance Max campaigns.
