How Can Seasonal Trends Be Leveraged to Adjust Target ROAS Bids in Google Ads?

Shad Super -

Summary

Seasonal trends can significantly influence consumer behavior, making them an essential consideration when adjusting Target ROAS (Return on Ad Spend) bids in Google Ads campaigns. By analyzing historical data, leveraging Google's tools like seasonality adjustments, and actively monitoring performance, advertisers can maximize returns during high-demand periods or conserve budget during slower seasons.

Seasonal trends refer to predictable changes in consumer behavior tied to specific times of the year, events, or holidays. These trends affect search volume, competition, and conversion rates. For instance, retail sales often increase during Black Friday and Cyber Monday, whereas travel and tourism experience peaks during summer vacations or major holidays.

By identifying these patterns, advertisers can align their Google Ads strategy with customer behavior, ensuring optimal budget utilization and higher ROAS.

1. Analyzing Historical Performance Data

Start by reviewing historical performance data in Google Ads and Google Analytics. Look for trends in conversion rates (CVR), cost per click (CPC), and overall revenue during specific timeframes. This helps identify periods where customers are more likely to convert.

For example, if your e-commerce site consistently sees higher conversion rates in December, you may want to increase your Target ROAS bids leading up to the holiday season to capture more conversions.

2. Using Seasonality Adjustments in Google Ads

Google Ads provides a feature specifically designed for seasonal trends: Seasonality Adjustments. These are ideal for short-term events like holiday promotions or flash sales where conversion rates temporarily spike.

To implement seasonality adjustments:

  • Navigate to Tools & Settings → Bid Strategies → Advanced Controls → Seasonality Adjustments.
  • Specify the date range, conversion rate adjustment, and scope (e.g., Campaign or Account level).

For example, if you anticipate a 20% increase in conversion rates during a promotion, you can input this adjustment to allow Google’s automated bidding strategies to optimize accordingly.

3. Modifying Target ROAS Goals

During peak seasons, consider adjusting your Target ROAS goals to allow for more aggressive bidding. For instance:

  • Lowering your Target ROAS slightly during high-conversion periods can increase ad visibility and drive volume, as it signals to the algorithm to prioritize conversions over strict efficiency.
  • Conversely, increase your Target ROAS during slower seasons to maintain profitability while reducing spend.

It's essential to test these adjustments incrementally and monitor results to avoid overspending.

4. Leveraging Automated Bidding Strategies

Google’s Smart Bidding, including Target ROAS, uses machine learning to optimize bids for each auction based on real-time signals. Ensure your campaigns are structured to take full advantage of these capabilities, especially during seasonal trends:

  • Enable conversion tracking and set accurate values for each conversion to provide the algorithm with reliable data.
  • Account for external factors, such as shipping delays, that may impact conversions during peak seasons.

5. Budget and Creative Adjustments for Seasonal Relevance

Complement your Target ROAS adjustments with budget increases for high-performing campaigns and seasonally relevant ad creatives. Seasonal ad copy can improve CTR (click-through rate) and Quality Score, which in turn reduces CPC.

For example:

  • Retail: Highlight discounts or limited-time offers during Black Friday.
  • Travel: Emphasize summer vacation deals or holiday packages.

Monitoring and Evaluating Results

Real-Time Monitoring

Use real-time reporting in Google Ads to monitor the impact of your adjustments. Key metrics to watch include:

  • ROAS
  • CTR
  • Conversion Rate
  • Impressions and Spend

A/B Testing Adjustments

Test different Target ROAS values across multiple campaigns or ad groups to determine optimal performance. For example, set one campaign to a 300% ROAS target and another to 400% to see which delivers better results during a seasonal peak.

Post-Season Analysis

After the seasonal period ends, evaluate your campaign performance to identify successes and areas for improvement. Use this data to refine future strategies.

Conclusion

Leveraging seasonal trends to adjust Target ROAS bids in Google Ads involves a combination of historical analysis, seasonality adjustments, tailored bidding strategies, and real-time monitoring. By proactively aligning your campaigns with predictable consumer behavior, you can maximize returns during high-demand periods while staying efficient during slower seasons.
