Whether it’s chasing weekly specials, comparing grocery prices or trying to make the shopping budget stretch a little further, Australians have plenty of reasons to keep an eye on their supermarket spending.
But when it comes to searching online is there a clear preference for one national supermarket over the other?
Google Trends data comparing searches for Coles, Woolworths and Aldi across the nation over the past year reveals that without a doubt Coles and Woolies recorded the highest average search interest both scoring 55, while Aldi sat considerably lower at 19.
Woolworths experienced the most noticeable fluctuations, demonstrating two significant peaks around the beginning of the year and again in March and April. Coles also experiences increases during these periods, although its search interest remained comparatively consistent throughout the year. Aldi maintained a much lower but relatively steady level of interest.
These figures come amid an ongoing scrutiny of Australia’s supermarket industry as households continue to navigate the cost-of-living crisis, pressures and rising grocery expenses.
The standout peaks in search interest throughout the year primarily reflects seasonal shopping habits, promotional campaigns and increased attention around major shopping periods. Ultimately, the figures highlight the ongoing competition between Australia’s supermarket giants, with Coles and Woolies attracting much more search interest than Aldi.
The paradox of this investigation is that if most people tend to research supermarkets to see the cheapest options for them, why isn’t Aldi skyrocketing? A CHOICE grocery comparison published in September 2025 found that Aldi offered the cheapest basket of 15 everyday items compared to Coles and Woolworths.
This could be looked over because Aldi has already established itself as a cheaper alternative so Australians don’t need to search for that answer. It might also correlate to a convenience factor. There are 1,142 Woolworths, 878 Coles and 613 Aldi’s across Australia. Shoppers tend to shop near their location’s proximity, and if Woolies has almost twice as many stores as Aldi they would clearly have more brand visibility.
