(6) Minimizing the CPM During Black Friday
- Why your CPM goes up
- When does it go up
- How to reduce the CPM
Why your CPM goes up
- Everybody increases the budget, but the ad stock (placements and impressions) are the same
So there are more bidders per unique impression - Low ad engagement / Negative engagement
You have an ad running, and after spending 100-500€ it doesn’t have comments, very low CTR, has 1 like and 3 dislikes, and 1 person reported it. - You are being out-bid
Your competition is doing manual overbidding,
Or they make crazy budget increases - Retrieval saturation
During BF, billions of new ads are launched
→ weaker retrieval signals
→ your ads get ranked lower unless your creative has high engagement or strong signal quality
