Happydemics analysed 1,641 brand lift studies run across 15 APAC markets between May 2021 and September 2026. Of the four regions compared, APAC is the only one whose advertising year peaks in December. And while December campaigns in the region are remembered more than usual, they do less for the brand than campaigns run in any other month.
Elsewhere in the world, that extra December attention turns into stronger brand results. In APAC, the season works at the top of the funnel and stalls below it. For anyone planning APAC holiday advertising, that affects how you plan the season as much as how you judge it afterwards.
About the Data
The analysis draws on Happydemics’ database of brand lift study results for APAC: 1,641 studies run for 67 client organisations across East Asia, Southeast Asia, South Asia and Oceania. Comparisons with the rest of the world draw on between 13,380 and 14,070 campaigns, depending on the metric, and the median APAC campaign ran for 31 days.
Each study compares people exposed to a campaign with a statistically similar control group, so the results capture the incremental effect of the advertising itself. Two measures carry most of the story.
Ad Recall and the Impact Score
People’s ad recall tells you whether they remember seeing the advertising. The Impact Score summarises how a brand lift performed across all of its KPIs at once, on a scale of 0 to 100. Each KPI, such as consideration or brand image, is ranked against comparable campaigns using benchmarks built from media type, industry and market, and the Impact Score is the average of those rankings. When December’s Impact Score falls, December campaigns are ranking lower against their peers on the brand outcomes they were bought to move.
One caveat before the findings: the regional December signal is driven mainly by Japan, and some country readings rest on small samples. Sample sizes appear alongside the numbers throughout.
APAC Runs on a Different Q4 Clock
To compare seasonality, Happydemics indexed the days campaigns were live in each month against each region’s own average month (index 100), using the complete years 2023 to 2025. Western Europe, North America and Latin America all peak in November, around Black Friday. APAC peaks in December, at 175. The index tracks measured campaign activity rather than total ad investment, so the shape of the year matters more than the level.
A one-month gap sounds minor. In practice, it’s enough for a Q4 plan imported from a Western headquarters to land before APAC’s own peak and ease off just as advertising in the region intensifies.
Peaks Vary From Market to Market
The regional curve also hides wide differences between markets. Among the seven APAC markets with at least 40 campaigns, December is the busiest month in four: Japan (index 172), India (200), Singapore (188) and the Philippines, where December activity reaches 279, the most concentrated peak in the region.
Australia, Malaysia and Thailand keep their own clocks. Australia peaks in September (166), Malaysia in July (207) and Thailand in May (221), shortly after Songkran. Malaysia and Thailand also have thin December activity, with only 10 and 6 advertisers respectively live that month.
The practical step is to build the Q4 calendar from the country up. A single regional plan built around Christmas would still miss the peak in three of these seven markets, and one built around Black Friday would miss it in all of them.
December Buys Attention, but Not Brand Impact
The more consequential finding is what December campaigns achieve once they’re live. Comparing December with every other month, while holding country, media, industry, organisation and year constant, December campaigns in APAC gain 2.3 points of ad recall. That’s in line with the rest of the world, where recall rises 2.1 points. The gap opens up on brand impact. Outside APAC, December’s Impact Score rises 1.6 points, while in APAC it falls 2.5 points.
December campaigns in APAC get noticed and remembered, but that attention isn’t carrying through into the brand outcomes advertisers are paying for, such as consideration and brand image.
A Problem That Starts in October
The monthly view, which compares each month with APAC’s annual average, shows how the pattern builds. December is one of the two strongest months of the year for recall and the weakest for brand impact, at 2.4 points below the average month. The weakness doesn’t start at Christmas, either. October and November both sit below average on Impact Score, and October records the lowest recall of the year, 3.1 points under average, just as year-end pressure starts to build.
Two changes follow for planning and reporting. The first is to benchmark December against December. Judged against an annual norm, a campaign that performed well for the season can look like a failure, and a weak one can hide behind strong recall. The second is to treat high recall as the starting point for advertising effectiveness measurement. In December especially, recall confirms the ad was noticed, while whether the brand benefited needs its own measure.
The Regional Average Hides Very Different Decembers
Because the regional December drop is driven mainly by one market, country-level results tell a more useful story than the APAC average.
Japan: Recall Holds, Brand Impact Falls
Japan shows the clearest December drop in the region. Recall holds up at peak volume, but brand impact falls 5.9 points compared with Japan’s other months (49 December campaigns). Christmas and Oshogatsu, the New Year holiday, make December Japan’s busiest month for advertising, so festive visibility is easy to come by. Brand effect is much harder to win.
Australia: December Still Delivers
Australia tells the opposite story. December recall rises 3.0 points and brand impact holds steady (46 December campaigns). The Christmas and Boxing Day period, which coincides with the start of summer, gives brands a natural reason to be part of the conversation.
India: No Penalty, No Premium
India’s December performance doesn’t move in either direction. December is India’s heaviest month by live campaign days (index 200), yet campaigns perform much as they do the rest of the year. With 16 December campaigns, the base is too small to draw firm conclusions from, and in India the timing that matters most is Diwali, which we look at next.
For regional teams, the takeaway is to report December performance with country components and sample sizes next to the APAC figure. A strong Australian result and a weak Japanese one can blend into a regional number that describes neither market.
Diwali Shows Why Recall Alone Can Mislead
Diwali anchors festive season advertising in India, and it offers the clearest example of why strong recall and strong brand outcomes don’t always travel together. To isolate the festival effect, Happydemics compared Indian campaigns running in the five weeks before Diwali, using the actual festival dates from 2021 to 2026, with Indian campaigns at other times of year. That gives 54 campaigns inside the window and 197 outside it.
Inside the window, it’s harder to be seen. Ad recall drops 7.6 points, and attribution, which measures whether people link the ad to the right brand, drops 6.3 points. Brand image slips 2.4 points. Judged on those measures alone, Diwali looks like a poor time to advertise.
Consideration points the other way, rising 3.2 points in the same window. Audiences are harder to reach and less likely to remember who advertised to them, but the people a campaign does reach are readier to buy.
That changes how Diwali campaigns should be briefed and judged. A campaign measured on recall alone would be written off, even if it moved consideration as far as the season allows. The attribution drop is the part to fix: in a crowded festive window, branding has to work harder so the right brand gets the credit.
The Formats Built for Attention Lose the Most Brand Effect
Format-level results show where December clutter does the most damage. The table compares each format’s December performance with the same format in other months across APAC, in points. Share of voice here refers to a format’s share of the campaigns Happydemics measured, not total market spend.

|---|---|---|---|

Display and online video lose the most brand impact in December, falling 5.4 and 8.3 points, yet recall for both barely moves. Audiences still see these ads and still remember them, so whatever goes wrong happens after the exposure.
Budget weight doesn’t explain the pattern. Display takes a far larger share of December campaigns than it does in any other month, while online video’s share hardly changes, and online video still loses more brand impact than display.
For media and creative teams, the December priority in attention formats is brand linkage: making sure an ad that’s seen and remembered is also tied to the brand that paid for it.
Spending More Won’t Protect December’s Performance
December also changes who you’re competing with. Across APAC, food and beverages gains 6.6 points of share of voice in December compared with the rest of the year, electronics 3.7 points, cosmetics and skincare 3.1 and luxury 1.3. Tourism gives up 3.4 points and banking 1.0. A brand that leads its category in March can find itself a minor voice in December, so December share-of-voice assumptions need their own baseline.
Crowding in doesn’t predict how a category performs. Food and beverages gains the most share of voice and improves on both recall (+2.4) and Impact Score (+1.8) across 36 December campaigns. Electronics also gains share and recall (+3.0), but its Impact Score falls 10 points (23 campaigns), which is the region’s December pattern at its most extreme. At a broader level, FMCG (44 campaigns) and retail and lifestyle (34) both come through December largely intact on brand impact, at −0.7 and +0.5 points respectively.
What seems to protect performance is relevance to the moment. Food and drink has a natural place in year-end celebrations, and Australia’s festive summer gives brands a reason to speak. That’s an interpretation more than a rule, and electronics, a common gift category that still loses ground, shows it isn’t the whole explanation. It still makes a useful test for any December brief: does this creative have a clear reason to exist in this market, at this moment?
Three Things Worth Testing in Your Next Q4 Campaign
The data shows where December falls short, but it doesn’t yet prove what fixes it. Happydemics frames the following as hypotheses to test, each tied to a signal in the data.
Tighter Audience Focus
An early signal across 84 campaigns suggests that in December, extra reach no longer buys extra recall. The test is whether concentrating weight on audiences already in market for the category lifts consideration more than buying additional reach.
More Distinctive Branding
With several categories crowding in and attribution falling 6.3 points during Diwali, it’s harder for an ad to be credited to the right brand at year end. The test is whether stronger, earlier branding improves attribution, and whether formats that stand apart from the festive clutter help further. To measure creative impact on brand metrics, compare those outcomes across executions.
Clearer Commercial Messaging
At Diwali, consideration rises even as recall falls, a sign that audiences are readier to buy. The test is whether product-led creative with a clear offer turns that readiness into stronger brand outcomes.
Whichever you test, read results market by market and against a December baseline instead of the annual average. Measuring while campaigns are live helps too. In a festive window only a few weeks long, a result that arrives after the campaign ends can only inform next year’s plan.

Measuring Holiday Campaigns With an Independent Partner
To prove campaign impact, it is essential to separate what the advertising did from what was already happening in a market. Happydemics helps brands by measuring brand lift and supporting better-informed campaign decisions. It compares people exposed to a campaign with a statistically similar control group, using non-incentivised, panel-free surveys, so results reflect how real audiences respond.
Benchmarks covering more than 80,000 data points across 13 channels put each result in context against comparable campaigns by market, media type and industry. For teams running APAC holiday advertising, that makes it possible to judge December on its own terms and, with in-flight measurement, to see brand results while campaigns are still running and adjust inside the festive window.
Discover how Happydemics helps brands measure the real impact of their holiday campaigns across APAC through independent brand lift studies.
