December planning
Your December ad budget buys 22% less than it did in January.
December is the most expensive month of the year to rent attention. Q4 CPMs run 20 to 50 percent above baseline, and the two weeks before Christmas are the peak of the peak.
That is not an argument against paid social. It is an argument about what you still have on January 1.
Rent goes up in December. It does not come with a lease.
Three numbers set the December problem. None of them are controversial, and all three come from the ad industry's own reporting.
Put your December number in.
The same budget, two ways: what it rents at December rates, and what it renders instead.
Rented side: budget divided by a $25.49 CPM (Gupta Media, Q4 2025 US average). Rendered side: published Ditto tiers, Launch $5,000 for up to 2,500 deliveries at 6 assets each, Campaign $12,000 for up to 10,000 at 12 assets, Scale $25,000 for up to 50,000 at 18 assets. The slider spans the published tiers. Above $25,000, Enterprise is custom scale on the same model.
Those are not the same unit, and that is the whole argument.
An impression is a moment of maybe. A delivery is a person receiving something built from their own data, which they keep, and which a good number of them post themselves.
Comparing the two straight across would be unfair to the impression. The asymmetry is the point. One is a rental that ends when the invoice does. The other is an asset your audience carries into January and shows to people you never paid to reach.
Your audience is your distribution channel.
The reason December is the right month to do this is not that ads are expensive. It is that this is the month people actually want to look back, and they will carry it for you.
Earned reach, not bought
When someone posts the asset you made for them, their followers see it. That reach costs nothing and does not stop when a campaign ends.
Made specifically for every person
Not a template with a name dropped in. The asset is built from that person's own year, which is why they keep it and why it is worth posting.
It still exists in February
A December campaign that ends in December bought you December. Assets people keep are still working when the next planning cycle starts.
This is not theoretical.
Two campaigns built exactly this way, both with the work and the numbers published.
Stop renting your audience.
December is the most expensive month to rent attention, and the best month to give someone something worth keeping.
