Predictions for Q4 of 2024
Based on trends from previous quarters and 2023, here are the predictive insights for Q4 2024, which is often called the ‘5th quarter’ because of the holiday season:
1. Increase in Cost per Mille (CPM):
- The CPM steadily increased throughout Q4 2023, almost doubling by week 52, indicating strong demand during the holiday season. A similar trend is expected for Q4 2024, with CPMs likely increasing by 70-100% from the beginning to the end of the quarter, reflecting heightened competition for ad placements during the peak holiday shopping period.
2. Impressions Decline, Cost Increase:
- In 2023, there was a gradual decline in impressions from weeks 40 to 47, followed by a resurgence starting in week 48. This suggests that while users may engage less leading into December, ad demand spikes again closer to major holiday sales. For 2024, we can expect a similar pattern, with impressions likely to decrease by around 30% early in Q4 but rebound by 10-15% toward the end.
- Despite the decline in impressions, costs continued to rise, indicating more expensive inventory. Costs are expected to increase by 50-60% throughout Q4 2024, reflecting premium pricing for holiday advertising.
3. Impression Recovery Towards End of Quarter:
- In 2023, the resurgence in impressions started in week 48 and continued into week 52, likely driven by Black Friday, Cyber Monday, and holiday promotions. This trend will likely repeat in 2024, with a 10-20% boost in impressions starting around week 48, peaking in weeks 51-52.
4. Increased CPM and Spend Efficiency:
- In 2023, CPMs surged after week 46, with a 50% increase in CPM from weeks 46 to 52. In 2024, this trend will likely occur earlier, as advertisers increasingly compete for limited holiday inventory. Expect CPMs to rise by 60-70% during this time, especially from weeks 47-52.
5. Predicting Cost-Effectiveness:
- As seen in 2023, even with higher CPMs, impressions per dollar tend to stabilize by the end of Q4, when spending reaches its peak. For 2024, advertisers should prepare for more cost-efficient impression delivery towards the end of the quarter, when they can get 20-30% more impressions per dollar than in mid-Q4.
6. Strategic Bidding Timing:
- Advertisers should focus on maximizing efficiency by frontloading spend in the earlier part of Q4 (weeks 40-46) when CPMs are relatively lower, and then ramp up again in the last few weeks (weeks 48-52), where competition is fierce but potentially more valuable for holiday campaigns.
Q2 2024

- Puzzle and Casual games stand out, capturing about 40% of the total auctions in games.

- Interestingly, the Books category maintains a notable number of auctions, coming in just behind Social, suggesting consistent user interest and an opportunity for targeted advertising.

- In Q2, iOS saw more than 2x the number of auctions than Android, with iOS 17 almost 4x more than all other iOS versions combined.
