Zepto, Blinkit and Amazon emerge as competing marketing channels for brands

What to watch

• Launches of self-serve ad products, sponsored-search inventory, retail-media APIs or standardized campaign reporting by Zepto or Blinkit.
• Evidence that quick-commerce advertising drives incremental sales rather than merely reallocating existing marketplace or offline demand.
• Rising sponsored-placement CPCs/CPMs and increasing share of brand budgets committed to retail media.
• Brands consolidating commerce-media buying, measurement and creative operations under one team or agency.
• Platform moves to link advertising exposure with loyalty, first-party audience segments, repeat purchase or closed-loop sales.
• Category-specific adoption in high-frequency, impulse-led segments such as snacks, beverages, personal care, beauty and household essentials.
• Changes in delivery fees, minimum order values, dark-store coverage or assortment breadth that alter shopper frequency and ad inventory quality.
• Build a channel-role framework rather than treating all commerce media as interchangeable: Amazon for search and consideration, quick-commerce for urgency, replenishment and local activation.
• Run geo-matched incrementality tests across Zepto, Blinkit and Amazon using a common KPI set: new-to-brand rate, repeat purchase, contribution margin, basket attachment and post-campaign retention.
• Negotiate for category-level audience, search-query, placement and incrementality reporting before committing annual spend.
• Shift creative toward mission-based formats such as occasion bundles, add-on prompts, time-of-day offers and stock-aware messaging.
• Model media cost together with trade spend, fulfillment economics, discounting and platform commissions; optimize for profitable orders rather than ROAS alone.
• Prepare for auction inflation by reserving launch-period inventory and developing organic discoverability through assortment, ratings, availability and platform-native content.
