Quick answer
Start planning your Christmas campaign in September, and have it running by late October or early November. The peak trading weeks are the busiest of the year for most retail and hospitality businesses, so the shops that win are the ones already front of mind before shoppers start buying. Early planning also gets you better ad availability and rates, and time to fix anything that is not working.
Why early wins
Three simple reasons.
Shoppers decide sooner than you think. By the time the town centre lights go on, a lot of people have already chosen where they are spending. If your name is not in their head by early November, you are fighting to change a decision that is half made.
Advertising space and rates. Christmas is the most contested advertising window of the year. Book late and you take what is left at the price that is left. Book early and you get the slots you want at a calmer rate.
The businesses that win Christmas are not the ones that shout loudest in December. They are the ones people already had in mind in November.
Room to adjust. A campaign that starts in early November gives you weeks to see what is landing and shift budget towards it. A campaign that starts in December gives you days.
A month-by-month plan
Treat this as a template you can reuse every autumn.
August to early September: think Look back at last Christmas. What sold, what did not, what did customers ask for that you did not have? Set one clear goal (footfall, bookings, online orders, gift vouchers) and a budget you are comfortable with.
September: plan Decide your offer and your message. Choose your channels. If broadcast or outdoor is part of the mix, this is when to enquire, because you are booking ahead of the rush. Brief anyone making creative for you now.
Early October: build Get the creative made: ad scripts, social assets, window displays, email templates. Sort stock and staffing for the busy weeks. Nothing should be left to make in November.
Late October to early November: launch Go live. This is early enough to catch the planners and the organised gift buyers, and it means your name is already familiar when spending peaks. Run consistently rather than in one short burst.
December: push and capture Layer in last-minute and last-posting-date messages, gift vouchers for the truly late shoppers, and clear opening hours everywhere. Keep your Google Business Profile and listings bang up to date.
Early January: review Note what worked while it is fresh. Next year's plan starts here.
