The second half of the year is when commerce apps make (or miss) their biggest growth opportunities. While the highest sales volumes occur between November and December, successful marketers start preparing months in advance by testing creatives, diversifying acquisition channels, and building high-intent audiences before competition peaks.
The opportunity is significant. Global online holiday sales reached a record $1.29 trillion during the 2025 holiday season, growing 7% year over year, while mobile accounted for 56.4% of online holiday revenue for the first time, reinforcing that smartphones have become the primary shopping channel for consumers worldwide.
This calendar highlights the key commerce moments from August through December and outlines how app marketers can prepare for each stage of the shopping season.
August
Start Planning Before Everyone Else
Although August doesn’t feel like the holiday season, it’s when the most successful e-commerce marketers begin preparing for Q4.
Key moments
- Back-to-School (global)
- Summer Bank Holiday (UK)
- End-of-summer promotions
Focus for marketers
- Refresh creative assets
- Test new acquisition channels
- Launch incrementality experiments
- Build remarketing audiences
- Validate campaign messaging before CPMs increase
AVOW Insight: August is an ideal time to acquire users before media costs rise sharply in October and November.
September
Build Your Holiday Growth Engine
September is all about optimization. By the end of the month, your acquisition strategy, creatives, budgets, and audience segmentation should be finalized.

Focus for marketers
- Scale winning campaigns
