Seasonal advertising in Google Ads: planning budget by month
The same budget month after month is a comfortable choice for accounting and almost always the wrong one for a seasonal business, where demand swings by multiples.
Map your seasonality curve in advance
Before planning a budget, chart demand by month using previous years — Google Trends data for the Uzbekistan region on the niche's key terms gives a first approximation even if the business has no sales history of its own.
Most niches carry more than one seasonal peak a year: air conditioners peak in summer but have a secondary spring peak when people prepare early and buy cheaper before the main seasonal price rise.
Track local peaks specific to this market separately — Navruz, the start of the school year, wedding season — they don't always align with general market trends visible in generic analysis tools.
When to ramp budget up ahead of a peak
Raise budget two to three weeks before the expected demand peak, not once it has already started — the auction heats up early as competitors prepare for the season too, and click price near the peak itself is usually higher than a few weeks out.
For complex purchases with a long decision cycle — property ahead of wedding season, renovation before holidays — start increasing budget even earlier, a month to six weeks out, to catch people at the early planning stage.
Set aside part of the annual budget specifically for the seasonal peak in advance rather than trying to find the money in the moment — businesses that cut budget too hard off-season don't recover campaign momentum in time for the next peak.
What to do off-season
Stopping ads completely off-season is a common mistake: the account loses accumulated statistics and automated bidding's learning history, and the next peak effectively means restarting the campaign from scratch.
Lower budget, but not to zero — a minimal maintenance level that keeps the campaign active and continuing to accumulate conversions saves ramp-up time before the next season.
The off-season is a good time to test new ad copy, landing pages and keywords with lower risk, since the cost of a mistake at low traffic is smaller than during the peak, when every click is expensive.
Using remarketing between seasons
The audience gathered during last season's peak stays valuable off-season — remarketing to people who showed interest in the product last year costs less than cold traffic and can bring them back ahead of a new season.
For products with a long usage cycle — climate equipment, heating systems — set up reminder remarketing a month to six weeks before the next season, when people start thinking about the topic again.
Don't show the same remarketing creative year-round — refresh the offer to match the current context, or the audience gets used to the banner and stops responding well before the next seasonal peak.
A practical annual plan
Build a month-by-month plan with an expected demand index relative to the yearly average — a foundation for allocating the annual budget instead of intuitive decisions made afresh each month.
Revise the plan yearly against the account's actual data rather than relying on the first year's forecast indefinitely — the market and competition shift, and the seasonality curve can move over time.
Keep a flexible reserve of 10-15% of annual budget for unforeseen demand spikes — external events sometimes create an unexpected local peak not in the original plan, and being ready to increase spend quickly gives an edge over slower-reacting competitors.
