Indian SMBs comparing Instagram and YouTube ads for 2025 campaigns

The Digital Ad Dilemma for Indian Business

As of June 13, 2025, India’s digital ad market is booming, with 80% of SMBs relying on online advertising and 76% finding it more effective than traditional methods (IBEF, 2024). In 2024, Indian SMBs spent $5.82 billion on digital ads, an 11.9% jump from the previous year (Meltwater, 2025). For small and medium businesses (SMBs) in cities like Mumbai, Bengaluru, and Pune, choosing the right ad platform is critical to maximize ROI in a $7.9 billion internet ad market (PwC, 2023-27). Instagram and YouTube stand out, with 363 million and 462 million ad reach respectively in India (Statista, 2024). 

But which delivers better results for SMBs? Atom Communication, a digital marketing observer, notes, “It’s not about the platform—it’s about the strategy.” This blog compares Instagram and YouTube ads for Indian SMBs in 2024, backed by A/B test results from Indian campaigns, stats, and insights to guide your ad spend.

Why Instagram and YouTube Matter for SMBs

Instagram Ads: Strengths and Costs

Strengths
