Why Your Festive Ads Will Cost More This Year (and How Not to Overpay)

Your festive ads cost more because ad platforms are auctions, and in October and November every brand in India is bidding for the same attention at the same time. The supply of feed space does not grow for Diwali. The number of advertisers competing for it does. Agencies commonly report festive CPMs running 30 to 50 percent above normal, and roughly tripling around peak sale moments.

Here is the part most brands miss: what you pay in November is largely decided in August and September. With Navratri on 11 to 19 October and Diwali on 8 November this year, the cheap window is open right now.

The short version

• Ad costs rise in the festive season because of competition, not because your ads got worse.
• Cold traffic is what gets expensive. Warm audiences stay comparatively cheap.
• August and September are when you build those warm audiences at normal prices.
• If you start in late October, you are buying your audience at the worst possible moment.

Why do ad costs go up during the festive season?

Meta and Google do not set a price for an ad. They run an auction for each impression, and the winner is whoever combines the strongest bid with the most relevant ad. When thousands of Indian brands switch on festive campaigns in the same fortnight, the number of bidders per impression jumps while the inventory stays roughly the same. Prices rise accordingly.

The season has a clear shape this year:

Moment	Date	What happens to costs
Now (August)	Quiet	Normal rates, the cheapest time to build audiences
September	Warming up	Still reasonable, competition begins to build
Navratri	11 to 19 October	Sharp climb, ethnic wear and festive categories go hard
Dussehra	20 October	Sustained high
Diwali	8 November	Peak, the most expensive fortnight of the year

In Gujarat this curve is even steeper, because Navratri is not a nine day marketing window here, it is the cultural centre of the year.

How much more expensive does it actually get?

Treat published benchmarks as directional rather than gospel, since costs vary enormously by category, creative and audience. That said, the numbers agencies report in India cluster consistently:

• Festive CPMs 30 to 50 percent higher than off-season rates.
• Roughly 3x during the biggest sale events, when the large marketplaces are spending heavily.
• Typical Indian Meta CPMs sit in the low hundreds of rupees for e-commerce, so a 40 percent rise is a real line item, not a rounding error.

The important thing is not the exact multiplier. It is that the increase applies to cold audiences, people who have never heard of you. Reaching someone who already knows you barely moves.

What should you do in August and September?

Spend now to build an audience you can talk to cheaply later. This is the single highest leverage move available to you, and the window closes in about six weeks.

Concretely, run awareness and engagement campaigns during these quiet months with the deliberate goal of filling your retargeting pools:

• Video views (people who watched 50 percent or more)
• Instagram and Facebook profile engagers
• Website visitors, captured via the Meta Pixel and Conversions API
• Your email and WhatsApp lists, uploaded as Custom Audiences

Come late October you are no longer paying peak prices to introduce yourself. You are paying to close people who already recognise you, which is a fundamentally cheaper conversation. Retargeting warm audiences is commonly reported to cost well under half what cold prospecting does.

If you do only one thing after reading this, do this one.

How do you keep costs down once the season starts?

Refresh creative more often than feels necessary. Stale creative gets algorithmically penalised with higher costs, and fatigue arrives faster in a crowded festive feed. Have your next two or three concepts ready before the current one tires. Swapping reactively always costs more than swapping on schedule.

Use Reels placements. Reels consistently deliver noticeably lower CPMs than feed placements, commonly reported in the 25 to 40 percent range. If you are producing festive video anyway, cut it vertical first. We wrote a fuller guide on reels that actually convert.

Let native beat polished. Creative that looks like it belongs on the platform tends to earn lower CPMs than obviously produced brand films. This does not mean lower quality, it means the format should feel native even when the craft is high.

Do not over-narrow your targeting. Very small audiences drive costs up, because you are competing for a thin slice of inventory. Broad targeting with strong creative usually wins in the festive auction.

Watch frequency. Cold audiences tire quickly, so keep exposure modest. Warm and bottom-of-funnel audiences tolerate far more, because they already know who you are.

What if your budget is small?

Do not try to out-spend marketplaces for cold reach in Diwali week. You will lose that auction, and you will pay to lose it.

Instead:

1. Pick one moment, not all of them. Own Navratri or own Diwali, not both badly.
2. Spend your budget on warm audiences and your own channels, where cost per outcome is far better.
3. Start earlier than the big brands, because early October is meaningfully cheaper than the first week of November.
4. Lean on organic and owned, email, WhatsApp and your existing followers, which cost nothing per impression at exactly the moment paid reach costs the most.

Your next eight weeks, as a checklist

• This month: switch on awareness and video campaigns purely to build retargeting pools
• This month: confirm the Meta Pixel and Conversions API are firing correctly, a broken signal now is an expensive problem in November
• By mid September: lock your festive offer and messaging, do not still be deciding in October
• By late September: produce creative in volume, several concepts, cut vertical for Reels
• By 8 October: campaigns live, ahead of Navratri rather than during it
• Through the season: refresh creative on a schedule, shift budget toward retargeting as costs climb
• After Diwali: the audiences you built are still yours, use them in the quiet months

The brands that look lucky in November are usually the ones that were organised in August. The auction rewards preparation more than budget.
