Illy Coffee: How We Grew Amazon UK Sales by 31% With TACoS Under 2%
The Challenge
Illy is one of the most recognised premium coffee brands in the world, and Amazon UK was a big opportunity to win more share in a crowded category. The catch was that you can’t win everywhere at once. Success depended on putting investment exactly where Illy had the strongest chance to win, capturing shoppers who were already looking for good coffee, and turning the UK from a side channel into a real growth engine inside the global business.
The Approach
We rebalanced the whole account. Where Illy already had strong organic visibility, we protected it instead of paying for what it was getting free. The spend we freed up went to products with greater growth potential. We improved copy and imagery so more visitors turned into buyers, backed the high potential ranges with strategic advertising, and kept one eye on the long game: winning new customers and growing subscribers, not just chasing a quick bump in sales.
The Impact
-
31%
sales growth in Q1 compared with last year.
-
4.96x
return on ad spend, efficient growth.
-
1.35%
TACoS, keeping ad spend well under 2% of total sales.
The Outcome
In Q1 2026 illy sold 31% more on Amazon UK than a year earlier, and March was the biggest month of the quarter. The growth was efficient too: every £1 spent on ads brought back £4.96 in ad sales, while total ad spend stayed at just 1.35% of overall sales. That balance is what moved Amazon UK from a promising channel to illy’s fastest-growing account worldwide. This builds on our earlier work with Illy Coffee.
