How Does Seasonality Impact Maximize Conversion Value Bidding Strategies in Google Ads?

Summary

Seasonality can significantly influence the performance of Maximize Conversion Value bidding strategies in Google Ads, as it changes user behavior, demand fluctuations, and competitive dynamics. Adjustments like seasonal bid adjustments or data exclusions should be adopted to ensure the bidding algorithm aligns with your business goals during such periods.

Understanding Maximize Conversion Value Bidding

Maximize Conversion Value is a Smart Bidding strategy in Google Ads that uses machine learning to optimize bids and deliver the highest total conversion value within a given budget. It factors in signals such as time of day, location, device type, and more to determine optimal bids.

This strategy performs well when past data and historical performance trends are consistent. However, during seasonal events, normal patterns may drastically change, requiring advertisers to intervene and guide the algorithm.

How Seasonality Impacts Maximize Conversion Value Strategies

1. Fluctuations in Demand

Seasonal events such as holidays (e.g., Black Friday or Christmas) or industry-specific peaks (e.g., tax season, back-to-school sales) lead to surges or drops in consumer demand. This directly affects performance metrics like conversion rates and average order values.

If your Maximize Conversion Value bidding strategy is not prepared for such variations, the algorithm might overbid or underbid, leading to suboptimal performance. For example, during Black Friday, if conversion values spike due to higher demand, the algorithm might not adjust quickly enough without intervention.

2. Competitive Changes

Seasonal changes often lead to increased competition as more advertisers bid aggressively to capture market share. This can inflate cost-per-click (CPC) and affect auction dynamics. Without proper adjustments, your campaign may either lose out on valuable conversions or exceed budget targets with diminishing returns.

3. Variability in Historical Data

Maximize Conversion Value relies on historical data to predict outcomes. Seasonal periods introduce anomalies in this data, which may mislead the algorithm when forecasting performance outside of these periods. For instance, strong performance during a seasonal peak might skew future bid predictions, reducing efficiency during non-peak times.

Best Practices to Manage Seasonality

1. Apply Seasonal Bid Adjustments

Google provides a Seasonality Adjustment tool for Smart Bidding strategies, including Maximize Conversion Value. This feature allows advertisers to specify anticipated changes in conversion rates during a specific time window. For example, if you expect a 30% increase in conversion rate during a promotion, you can configure this adjustment to guide bidding algorithms accordingly.

2. Use Data Exclusions

To prevent seasonal data anomalies from distorting future bidding decisions, you can use the Data Exclusions feature. By excluding outlier data from periods of unusually high or low performance, you ensure that the algorithm's learning process remains unaffected by short-term spikes or dips.

More details can be found here: [Data Exclusions, 2023].

3. Adjust Campaign Budgets

During high-demand periods, consider increasing your budget to capitalize on the surge in traffic and conversions. For example, allocating more budget during Black Friday ensures that the bidding algorithm does not restrict performance due to budget caps.

4. Monitor and Evaluate Performance

Track key metrics such as conversion value, return on ad spend (ROAS), and CPA throughout the seasonal period. Use real-time data insights to make on-the-fly adjustments to your campaign, ensuring performance aligns with expectations.

Example of Seasonal Impact

Consider an online retailer specializing in gift items. During the holiday season, the retailer expects a 50% increase in conversion rates and higher average order values due to gift buying. By applying a seasonal adjustment to account for the increase in conversion rate and raising the daily budget, the retailer ensures the Maximize Conversion Value strategy aggressively bids on high-value opportunities while maintaining a strong ROAS.

Post-Season Adjustments

After the seasonal event, it is equally important to revert any bid adjustments or budget increases. Allow the algorithm time to recalibrate based on the return to normal demand patterns. If data exclusions were set, ensure they are reviewed and applied correctly to prevent long-term impact.
