Q5: the cheapest traffic of the year is hiding between Christmas and mid-January

There is a window on Amazon that does not appear in the official calendar and that most sellers ignore completely. It runs from roughly 26 December to the middle of January, and the people who sell through it call it Q5.

It exists because of a mismatch. A large share of advertisers reduce or pause spend once Christmas delivery cut-offs pass, treating the year as finished. Shoppers do not stop. They have gift cards, returns credit and time off work. Demand stays meaningful while competition for it falls away.

What Q5 actually is

Q5 is not a real quarter. It is shorthand for the gap between the Christmas rush ending and normal Q1 trading beginning, when auction dynamics are temporarily distorted in the buyer’s favour.

Two things drive it. Budgets reset or run out at year end, and many sellers and agencies are simply not working. Campaigns that would normally outbid you are paused, capped, or being managed by nobody.

Why clicks get cheaper

Amazon advertising is an auction. Price is set by how many advertisers want the same placement. Remove a meaningful share of bidders and the clearing price falls, even with demand unchanged.

The practical effect is that the same keyword that cost you a painful amount in the second week of December becomes noticeably cheaper in the first week of January. Your bid has not changed. Your competition has.

Who is actually buying

Q5 shoppers behave differently from December shoppers, and the difference matters for how you advertise to them.

• Gift card holders. Money that exists only inside Amazon, mentally already spent. Price sensitivity is lower than usual.
• Self-purchasers. December buying is largely for other people. Late December and January buying is substantially for oneself, which changes which products and which search terms perform.
• Returns and replacements. People exchanging unwanted gifts, often for something in the same category.
• New-year intent. Fitness, organisation, planning, health. If your catalogue touches any of these, the window extends well past mid-January.

The practical implication: gift-oriented copy and bundles stop working on 26 December. Personal-benefit messaging starts working immediately. If you ran gift-angled campaigns in December, those are the ones to pause first.

How to structure the window

Keep this simple, because it is a short window and over-management wastes it.

1. Do not pause everything on 26 December. This is the single decision that costs the most. At minimum keep branded and best-performing exact match campaigns live.
2. Re-check your breakeven first. Post-Christmas discounting changes margin. Run the numbers in the breakeven ACoS calculator before deciding what you can afford.
3. Shift budget toward self-purchase terms. Pause gift-intent keywords, raise budget on core product terms.
4. Use the window for discovery. Cheap clicks are good clicks to learn from. This is a far better time to run broad match research than November was.
5. Watch inventory honestly. Q5 is worthless if you are out of stock, and January restock delays are common.

When evaluating what you find, the keyword decision tool is useful here specifically because it accounts for whether a term has had enough clicks to judge. In a short window it is easy to kill terms on far too little data.

When to stop

The advantage fades as advertisers return, typically through the second and third weeks of January. You will see it in your own CPC data before you see it anywhere else: costs drift back toward December levels.

At that point the window has closed and normal Q1 management resumes — which, as it happens, is its own distinct job. We have written about that in the January reset.

The summary is unglamorous: the main thing required to benefit from Q5 is to not switch off. Most of the advantage goes to whoever is still paying attention.
