This tool is particularly valuable during promotional events, sales periods, holidays, or any predictable fluctuations in consumer behavior that might temporarily affect campaign performance.
When you anticipate a significant change in conversion rates for a specific time period, such as a Black Friday sale or a limited-time promotion, you can apply a seasonality adjustment to help Smart Bidding strategies respond more effectively. The algorithm typically learns from historical data, but sudden changes can take time for the system to recognize and adapt to. Seasonality adjustments bridge this gap by providing the bidding system with advance notice of expected performance shifts.
To implement a seasonality adjustment, advertisers specify the date range, the campaigns or devices affected, and the expected percentage change in conversion rate. For example, if you expect conversion rates to increase by 50% during a weekend flash sale, you would input this information so the bidding algorithm can adjust bids accordingly during that specific period.
Best practices for using seasonality adjustments include reserving them for short-term events lasting one to seven days, as Smart Bidding can typically adapt to longer-term trends on its own. Advertisers should also ensure they have accurate historical data to estimate expected conversion rate changes. After the event concludes, reviewing actual performance against predictions helps refine future adjustments.
Seasonality adjustments work with various Smart Bidding strategies including Target CPA, Target ROAS, Maximize Conversions, and Maximize Conversion Value. This feature gives advertisers more control over automated bidding while still benefiting from machine learning optimization, making it an essential tool for managing campaigns during predictable periods of unusual activity.
Seasonality Adjustments in Google Ads Smart Bidding
What Are Seasonality Adjustments?
Seasonality adjustments are a Smart Bidding tool in Google Ads that allows advertisers to inform the automated bidding system about expected changes in conversion rates for upcoming events. This feature helps Smart Bidding algorithms account for short-term fluctuations that historical data alone cannot predict.
Why Are Seasonality Adjustments Important?
Smart Bidding relies on historical data and machine learning to optimize bids. However, certain events like flash sales, holiday promotions, or product launches can cause sudden spikes in conversion rates that the algorithm has not seen before. Seasonality adjustments bridge this gap by allowing advertisers to proactively signal these changes, ensuring bid optimization remains accurate during unusual periods.
How Do Seasonality Adjustments Work?
1. Setting the Adjustment: Advertisers specify a date range (typically 1-7 days) and the expected percentage change in conversion rate.
2. Scope Selection: Adjustments can be applied at the campaign or device level across Search, Display, and Shopping campaigns.
3. Algorithm Adaptation: During the specified period, Smart Bidding temporarily adjusts its bidding behavior to account for the anticipated conversion rate change.
4. Automatic Reversion: Once the event period ends, Smart Bidding returns to its normal optimization patterns.
Best Practices for Using Seasonality Adjustments:
- Use for short events lasting 1-7 days - Reserve for situations where conversion rate changes exceed 30% - Avoid using for predictable seasonal patterns (Smart Bidding learns these automatically) - Apply only when you have reliable data to estimate the conversion rate change
Exam Tips: Answering Questions on Seasonality Adjustments
Key Points to Remember:
1. Duration Matters: Seasonality adjustments are designed for short-term events. If a question mentions long promotional periods or gradual seasonal changes, seasonality adjustments are likely not the correct answer.
2. Conversion Rate Focus: These adjustments specifically target conversion rate changes, not traffic volume or impression changes.
3. Proactive Tool: Seasonality adjustments must be set before the event occurs. They are a planning tool, not a reactive solution.
4. Smart Bidding Requirement: This feature only works with Smart Bidding strategies like Target CPA, Target ROAS, Maximize Conversions, and Maximize Conversion Value.
5. Common Exam Scenarios: - Flash sales or limited-time promotions - New product launches - One-time events or annual sales
6. What Seasonality Adjustments Are NOT For: - Regular weekly or monthly patterns - Long promotional periods exceeding 14 days - Traffic fluctuations unrelated to conversion rates
When answering exam questions, look for keywords like 'upcoming sale,' 'short promotional period,' 'expected conversion rate increase,' or 'limited-time event' as indicators that seasonality adjustments may be the correct answer.
