Getting Ready for Q4
What to Check Before the CPM Surge
Q4 is the quarter that pays, and it is also the quarter you cannot prepare for once it has started. Download the guide to see what to check before Q4 arrives, and what you can now safely stop doing by hand.
Your Q3 Is the Window That Matters
Q4 pays more because of competition. CPM is driven by how many advertisers want the same ad space, and Q4 packs the biggest shopping events of the year into a few weeks while advertisers spend down annual budgets before they expire. More bidders means better prices for your inventory.
January is the mirror image. Advertisers pull back into planning mode and CPMs drop. Refinery89 network data shows this dip arriving every year, affecting publishers of every size rather than only small ones. A January drop is a pattern, not a sign that something broke.
The reason to act now is that almost everything worth fixing takes time to work. Content needs to be indexed and ranking, site speed changes need to reach real users, and new demand partners need to be live long enough to bid. Do the work in November and you are changing your ad stack during the surge you were trying to capture.
What Will You Learn About Q4?
CPM is a competition metric, and Q4 concentrates the year’s biggest shopping events into a few weeks. The guide includes an eCPM calendar for October, November and December, with Halloween, Singles’ Day, Black Friday, Cyber Monday, Christmas and New Year’s Eve marked, drawn from Refinery89’s 2026 Publishers’ Forecast.
Raising floors going into Q4 and bringing them down in January used to be a seasonal job you judged by feel. Single Tag now does it continuously, learning the best price for each combination of website, ad slot, country, device and time of day, and testing changes on around 10% of your traffic.
Six signals decide how well automated pricing can work for you, and the guide checks each one. It also puts them in order, because they are not equally urgent and the first one on the list is both the quickest to fix and the most expensive to leave broken.
End of Q3 Is the Deadline, Not the Warm Up
Everything on the checklist works gradually, so the work you finish in September is the work that gets paid in November.
The harder question is which item on that list is costing you money right now. That depends on your traffic, your geographies and how your placements are set up, and no checklist can tell you which one to start with on your specific site.
That part is worth a conversation. Our team reviews your current setup within 24 hours, tells you what is already working, and flags what would be worth changing while there is still time for the change to take effect. You do not need to have read the guide first.
If you already work with us, your Publisher Success Manager can go through your Q4 setup with you and confirm your signals are in good shape before October starts.
Have the conversation now. In November it might be too late.
