- Inflation: The economy and inflation are likely contributing to the rise in CPCs.

How do seasonal trends affect average CPC
Seasonal trends can significantly impact average cost-per-click (CPC) in Google Ads across different industries:
Seasonal Fluctuations in CPC
- The holiday season, including Thanksgiving, Christmas, and New Year, often sees a surge in online shopping and advertising, intensifying competition and causing CPCs to rise, especially in ecommerce and retail.
- The back-to-school season can also lead to higher CPCs for businesses selling related products like stationery, computers, and children's clothing.
- Summers are generally slower months for many businesses, auto dealers are noticing a decline in revenue, potentially leading to lower CPCs during this period.
Factors Driving Seasonal CPC Changes

- Increased demand for ad space and higher click-through rates (CTRs) during peak seasons can cause a rise in CPCs as advertisers compete more aggressively.
- Conversion rates and sales also increase during holidays, justifying the rise in CPCs to maintain visibility, but advertisers must balance this with avoiding overspending.
- Competitor activity, such as major promotions or new product launches, can sway the market, either driving up CPCs due to increased interest or decreasing them due to heightened competition.
Strategies for Managing Seasonal CPC Fluctuations

- Analyze historical data to identify patterns in search volume, conversion rates, and CPC during different times of the year to anticipate seasonal trends.
- Adjust daily budgets to accommodate increased demand during peak seasons, while maintaining a balance between CPC and conversions.
- Utilize automated bidding strategies like Target CPA or ROAS to effectively handle both long-term trends and short-term bursts, requiring minimal changes to take advantage of seasonal fluctuations.
- Regularly review and analyze conversion data to ensure campaigns remain agile and responsive to market dynamics, allocating more budget to profitable products during their peak seasons.

By understanding and leveraging the principles of seasonality, advertisers can optimize their Google Ads campaigns, ensuring they remain competitive and maximize their return on investment throughout the year.
