From Cadbury to Chatbots: What Diwali Ads Can Teach Your Brand Before 8 November
Diwali falls on 8 November this year. But if you work in marketing, you know the real festival started weeks ago, somewhere between the first Navratri reel and the first "Diwali Dhamaka Sale" notification on your phone.
Every year, brands spend crores trying to make us feel something in thirty seconds. Most of it is forgotten by Bhai Dooj. A few ads, though, stay with us for years. So before you plan your own festive push, let's look at what the legends got right, what has changed in 2026, and what you can actually do about it this week.
The ads we still talk about
Google, "Reunion" (2013)
In November 2013, Google India released a three and a half minute film about two old friends, Baldev in Delhi and Yusuf in Lahore, separated as children during Partition. Baldev's granddaughter uses Google Search to track down Yusuf's old family sweet shop, and the two friends meet again. The film was made by Ogilvy India, and it crossed 1.6 million views on YouTube before it even reached television.
The lesson: Google never once explained a feature. The product sat quietly inside a story about people, and search was simply the bridge that brought them back together. The emotion did the selling.
Cadbury Celebrations, "#NotJustACadburyAd"
Across 2020 and 2021, Cadbury Celebrations did something generous. With Ogilvy and Wavemaker, it used machine learning to create personalised ads in which Shah Rukh Khan asked people to shop at their neighbourhood kirana stores, sweet shops and boutiques. Shop owners could make their own version on a microsite. Over 2,000 stores were featured, more than 130,000 ads were created, and the campaign reached 94 million views.
The lesson: give people a role in your story. Cadbury made small businesses the heroes, and the whole country helped spread the ad in return.
Amul, the festive topicals
And then there is the Amul girl, who has been commenting on Indian life since 1966. Every festive season her topicals land in our feeds, and people still look out for them.
The lesson: consistency builds memory. You don't need one giant ad if you show up every year with the same voice, the same character and a fresh idea.
What's different this Diwali
A longer runway. Diwali is almost three weeks later than last year, so brands have more time to build up, and shoppers have more time to compare.
Shoppers are asking AI. According to MiQ, 43% of festive shoppers now discover brands through AI search tools, ahead of e-commerce platforms (30%) and social media (27%). If ChatGPT or Google's AI answers can't find clear information about your products, you are missing from the gifting conversation.
Creators are everywhere. Around 7,200 brands are expected to run creator-led festive campaigns this year, and festive influencer spend is projected at Rs 900 crore, up 29% from last year (Qoruz, via Agency Reporter). Most of that money goes to the biggest brands, which leaves plenty of room for local creators with loyal audiences.
Trust is catching up with discounts. InMobi found that brand trust (27%) now edges out discounts (22%) as a reason to buy. And 29% of shoppers buy a week or less before the festival, so your last week matters as much as your first.
Your Diwali checklist (steal this)
Pick one hero product. One gift, one story, one push. Spreading a small budget across your whole catalogue makes everything invisible.
Bundle instead of slashing prices. 52% of urban shoppers call themselves price comparers (Saarva), so a thoughtful gift pack often beats a flat discount.
Answer the questions people actually ask. "Best Diwali gift under Rs 1,000 for my boss?" Put clear, honest answers on your website and product pages so AI tools can find and recommend you.
Update your Google Business Profile. Festive timings, stock, fresh photos and your phone number. Late shoppers search "near me" first.
Work with two or three local creators instead of one expensive celebrity. Smaller audiences, more trust.
Plan the week after Diwali too. A thank-you message, a review request and a small loyalty offer keep the relationship going after the lights come down.
The real secret
The ads we remember had three things in common: a clear feeling, a real role for people, and the same voice year after year. That works for a chocolate giant, and it works just as well for the mithai shop down your lane.
