Abstract: Pick up any phone in Coimbatore and scroll for thirty seconds. You will run into a sponsored post, a discount notification, a product review, or an influencer talking about something they want you to buy. That is not an accident. It is an industry spending billions of rupees to be exactly where your attention is. But the more interesting question is not how much money brands are spending on digital marketing. The question is whether it actually changes what people buy — and if so, how. To find out, we surveyed 120 consumers across Coimbatore district between December 2024 and April 2025. We asked them which digital channels they use, which ones actually pushed them toward a purchase, and at what point in their decision-making process that push happened. Simple percentage analysis kept the numbers readable and the takeaways clear. The picture that came back is more interesting than a simple 'yes, digital marketing works.' Social media advertising leads as the top purchase trigger at 34%, but online customer reviews are right behind at 28% — and reviews are not something brands can buy or fully control. WhatsApp and email promotions account for 18%, search engine results for 12%, and influencer endorsements for 8%. Among respondents under 30, 62% said a strong online review had directly changed their mind about a purchase in the past six months. That is a big number. It means review management is not a support-desk activity — it is a marketing priority. At the same time, only 44% of respondents said digital marketing makes them more impulsive buyers. Most people in this sample are using digital content deliberately, to research and compare rather than to be swept into purchases they had not planned. That is worth taking seriously before you build a campaign strategy around urgency and FOMO. None of these findings are complicated, but they have real practical implications for anyone running a business or a marketing function in Coimbatore. The brands that will pull ahead in this environment are not necessarily the ones spending the most online — they are the ones that understand which digital channel actually moves their specific customer from curiosity to purchase.
