The brief, as we understood it
“
We created this category. We want to win it on the marketplace where India now shops for air conditioners, and to do it without simply paying more for every sale.
- Our reading of the brief handed to Milleniance at the start of the engagement
01 - The challenge

A name that invented the category, in a marketplace that doesn't care about heritage.

The client is a heritage air-conditioning brand. In a physical showroom, that history sells itself. On a marketplace, the category is crowded, every competitor bids on the same keywords, and visibility goes to whoever manages listings and advertising best.

The brand needed more than a presence. It needed sales that grew every year, with advertising that became more efficient as it scaled, not less.

  • Heritage did not automatically translate into marketplace visibility
  • Competing for the same high-intent keywords in a crowded category
  • Growth had to come with falling, not rising, advertising cost of sale

02 - The approach

Take over the marketplace programme, and fix the owned platforms behind it.

We took over the brand's Amazon marketing end to end, treating listings, content and advertising as one system rather than separate tasks, and tuning spend against the metric that matters: how much each sale costs to win.

In parallel, we rebuilt the brand's corporate website and e-commerce store on current technology, with strong graphics and animation, so the brand's own properties carried the same quality as its marketplace presence.

  • End-to-end ownership of marketplace marketing
  • Advertising spend optimised against ACOS, not just volume
  • Corporate website and e-commerce rebuilt alongside
