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

Shad Super -

Summary

Seasonality significantly influences the performance of Maximize Conversion Value bidding strategies in Google Ads. This automated bidding strategy relies on historical data and real-time signals to adjust bids and maximize the overall conversion value. Seasonal peaks or troughs, if unmanaged, can lead to inefficiencies, as Google’s algorithm may not immediately account for sudden shifts in demand or behavior. Leveraging seasonality adjustments and strategic planning ensures optimal campaign performance during these periods.

Understanding Seasonality in Maximize Conversion Value Bidding

Maximize Conversion Value is a Smart Bidding strategy that aims to optimize bids to achieve the highest return on ad spend (ROAS) by focusing on conversions with the highest value. However, it relies heavily on historical data and trends. When seasonality causes abrupt changes in demand, competition, or customer behavior (e.g., during holidays, sales events, or back-to-school periods), the algorithm may initially underperform as it adapts to the new conditions.

How Seasonality Impacts Performance

Seasonality can affect Maximize Conversion Value bidding in the following ways:

  • Increased Competition: During seasonal peaks, more advertisers may enter the auction, increasing costs-per-click (CPC) and competition for valuable ad placements.
  • Sudden Changes in Conversion Rates: Conversion rates may skyrocket or drop rapidly during seasonal events, which can misalign with the system’s bid predictions based on historical data.
  • Fluctuating Conversion Values: Seasonal promotions or product launches may alter the perceived value of conversions, influencing the strategy’s ability to optimize effectively.

Leveraging Seasonality Adjustments

Google Ads offers a tool called seasonality adjustments, which is particularly useful for addressing temporary and predictable changes in conversion rates. This feature informs the Smart Bidding algorithm about expected increases or decreases in conversion rates during specific dates. While seasonality adjustments don’t directly modify bids, they help the system prepare for short-term shifts.

When to Use Seasonality Adjustments

Seasonality adjustments are best applied in these scenarios:

  • Time-Limited Events: Examples include Black Friday, Cyber Monday, or flash sales.
  • Unpredictable Behavior: When historical data doesn’t reflect similar patterns, such as a new product launch during a holiday season.
  • Short Duration: Adjustments are ideal for events lasting 1–7 days, as Smart Bidding already accounts for long-term seasonality.

How to Set Up Seasonality Adjustments

You can create seasonality adjustments in Google Ads by following these steps:

  1. From your Google Ads account, navigate to Tools & Settings > Shared Library > Bid Strategies.
  2. Select Advanced Controls, then click on Seasonality Adjustments.
  3. Click the blue plus button to create a new adjustment.
  4. Define the relevant dates, times, and expected increase or decrease in conversion rates (e.g., +20%).
  5. Apply adjustments to specific campaigns or the entire account.

Best Practices for Managing Seasonality

Plan Ahead

Analyze historical data to identify recurring seasonal trends. Use these insights to prepare campaigns and set realistic goals based on conversion value targets. For example, if last year’s holiday sales drove a 30% increase in revenue, you can anticipate similar growth this year.

Combine Strategies

Maximize Conversion Value works best when paired with complementary tactics, such as:

  • Promotional Extensions: Use sitelinks, promotions, and callout extensions to highlight seasonal offers.
  • Dynamic Search Ads (DSAs): Automatically match ads to seasonal queries.
  • Audience Targeting: Focus on in-market and remarketing audiences to capitalize on high-value users.

Monitor and Optimize

During seasonal peaks, monitor performance closely. Key metrics to track include:

  • Conversion Value: Ensure the campaign is increasing total revenue effectively.
  • ROAS: Evaluate whether the strategy is maintaining profitability.
  • Impression Share and CPC: Track competition and adjust budgets as needed.

Post-Event Evaluation

After the seasonal event ends, review performance reports to assess the strategy’s success and inform future adjustments. For example, if conversion values exceeded expectations during a holiday sale, allocate larger budgets to similar campaigns next year.

Examples of Seasonal Impacts

Holiday Sales

Consider an e-commerce brand running a Maximize Conversion Value campaign during Black Friday. As conversion rates spike with increased traffic and demand, the algorithm needs to adjust bids in real time to maximize revenue. Using seasonality adjustments, the advertiser can prepare for this surge, ensuring higher bids for high-value products during peak hours.

Back-to-School Promotions

A stationery retailer launching a back-to-school campaign may face fluctuating demand over several weeks. By analyzing historical trends and applying seasonality adjustments, the retailer can focus on high-value conversions (e.g., bulk orders) and allocate budgets accordingly.

Conclusion

Seasonality plays a critical role in the success of Maximize Conversion Value bidding strategies. Advertisers can mitigate the risks of sudden demand fluctuations and competition by leveraging seasonality adjustments, planning ahead, and carefully monitoring campaign performance. Adopting these strategies ensures campaigns remain efficient and profitable during seasonal events.
