Google Introduces Seasonality Adjustments For Smart Bidding In Google Ads

Google is introducing seasonality adjustments for smart bidding Google Ads Search and Display campaigns.

Different Smart Bidding strategies like Target CPA and Target ROAS already consider seasonality, but advertisers just might want to adjust for significant conversion rate shifts. For example, during or following a product launch, or during a period of sales, an advertiser might want to apply extra seasonality adjustments for a campaign.

This will help Google’s machine learning improve campaign performance because it will expect a significant change in the conversion rate.

For these purposes, and to provide “more control in these rare situations,” Google is now introducing seasonality adjustments for Search and Display campaigns. Support for Shopping campaigns should be expected later on in the year.

Seasonality adjustments allow advertisers to apply predicted conversion rate adjustments in order for Smart Bidding to consider them for a specific date range while trying to hit a target CPA. Therefore, they should only be used if one is expecting major changes to conversion rates since Smart Bidding already consider seasonal events.

Advertisers on Google ads can now make seasonality adjustments and apply predicted conversion rate adjustments for Smart Bidding in Search and Display campaigns.
