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.
Note: Use seasonality adjustments only if you expect major changes to conversion rates, because Smart Bidding already manages seasonal events. 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, and Display campaigns.
