Ecommerce Advertising Rules in India are set to change how brands can legally advertise a discount, and the shift is bigger than it first looks. The Department of Consumer Affairs notified the Consumer Protection (E-Commerce) (Amendment) Rules, 2026 on September 9, 2026, and the rules come into force on January 1, 2027. Among the most consequential changes for advertisers is a new legal definition of “prior price”: any advertised price reduction must now be shown alongside the lowest price the product was actually sold at during the preceding 30 days, not an inflated reference price set just before a sale begins.

What the New Prior-Price Rule Actually Requires

The rule itself is specific: where a price reduction is announced, the prior price displayed alongside it must be the lowest price the product was actually offered at during the 30 days before the reduction, not simply the highest recent price or an artificially set reference figure. This directly targets a common promotional tactic, quietly raising a listed price for a short window right before a big sale so the advertised discount looks larger than the real price movement. Once the rule takes effect, that gap between the “was” price and the actual recent selling price becomes both commercially and legally risky to manufacture.

Sponsored Listings and Search Ranking Transparency

Beyond pricing, the amended rules require sponsored or paid product listings to be clearly and prominently identified as such, and marketplaces must disclose the principal parameters that determine how products and sellers are ranked in search results. Platforms are also barred from manipulating search results in ways that mislead shoppers or reduce the relevance of results to what they actually searched for. For brands buying retail media placement, this doesn’t necessarily change how visibility is purchased, but it does formalize a level of transparency around paid placement that was previously left largely to each platform’s own disclosure practices.

What This Likely Means for How Brands Plan Discounts

With prior price tied to a rolling 30-day window, promotional planning has to account for the entire pricing history leading into a sale event, not just the event itself. A brand that wants to advertise a genuinely large discount during a festive sale now needs pricing discipline in the weeks before it, since a price bump immediately before the event no longer produces a legitimate reference point. The more likely long-term shift is away from headline discount percentages as the primary promotional lever, and toward bundles, loyalty value, financing options, and after-sales service as ways to communicate value that don’t depend on manipulating a reference price. None of this is expected to end discount-led sales altogether, but it does push promotional planning toward longer horizons and tighter coordination between pricing, marketing, and legal teams.

The Compliance Side: Records, Audits, and Shared Responsibility

Substantiating a prior-price claim requires genuine historical pricing records and an audit trail a brand can produce if challenged, which is a meaningfully higher bar than most promotional calendars are currently built to support. E-commerce entities also need to comply with the existing Guidelines for Prevention and Regulation of Dark Patterns, 2023, conduct an annual self-audit, and display a compliance certificate prominently. Responsibility is explicitly split between marketplace and seller: platforms are accountable for how sponsored listings and rankings are disclosed, while individual sellers remain responsible for the accuracy of their own pricing and product claims. That split makes closer, ongoing coordination between a brand’s marketing, legal, and compliance functions less optional than it currently is for most teams.

The Market This Is Landing In

These rules take effect against a backdrop of rapid growth in Indian ecommerce advertising. WPP Media’s mid-2026 forecast puts India’s commerce advertising revenue at $3.9 billion for the year, up 29 percent year on year, while RedSeer Strategy Consultants projects India’s overall online retail market will exceed $90 billion in 2026, growing 22 to 24 percent annually. Amazon India has reported its seller base crossing 20 lakh, and Meesho reported 264 million annual transacting users and 2.67 billion orders placed in its most recent fiscal year. A regulatory change of this scale landing on a market growing this fast means the operational adjustment brands need to make isn’t a minor compliance footnote, it affects a genuinely large and still-expanding share of how Indian consumers shop.

How AKOI Approaches This

AKOI’s ecommerce marketing team builds promotional and pricing calendars with the 30-day prior-price window factored in from the planning stage, so festive and sale-event discounts stay both compliant and genuinely competitive once the new rules take effect, rather than requiring a scramble to rebuild pricing history close to the January 2027 deadline.

Conclusion

The Consumer Protection (E-Commerce) (Amendment) Rules, 2026 change the mechanics of how a discount can legally be advertised in India, and the practical work of adapting to them, building real pricing history, restructuring promotional calendars, tightening coordination between marketing and legal teams, needs to start well before the January 2027 deadline. The official government notification is worth reading directly for the full scope of what’s changing. Brands that treat this as a genuine pricing and promotional strategy shift, not just a legal disclosure update, are the ones likely to adapt with the least disruption to their festive and sale-event planning.
