Social Media Is Winning Product Discovery — But Search Still Captures Buying Intent
The debate over whether social media has overtaken search for product discovery tends to get framed as a straight contest, one channel replacing the other. The consumer data tells a more layered story. Shoppers don’t move through a single, tidy funnel from discovery to purchase. They bounce between platforms, and different channels do different jobs at different points in that journey.
GWI’s global consumer research, published through DataReportal’s Digital 2025 report, puts some real numbers behind this. Search engines remain the single largest source of brand discovery worldwide, cited by 32.8% of internet users, narrowly ahead of TV advertising at 32.3%. Social media ads sit close behind at 29.7%, but that figure has grown faster than any other major channel over the past two years, up 11.7% in relative terms since 2022.
Ecommerce search agency Searchflex points to the age breakdown as the more revealing detail here, rather than the overall ranking. Among 16 to 34 year olds, social media ads take the top spot for brand discovery, while search engines only overtake social ads from age 35 onwards. No single channel, at any age group, is cited by more than a third of respondents.
Why No Channel Wins Outright
That last point matters more than it first appears. If social media were genuinely replacing search, you’d expect to see one channel pulling decisively ahead as the dominant source of discovery. Instead, GWI’s data shows the average internet user cites 5.8 different sources when explaining how they discover new brands and products, a figure that’s stayed remarkably stable even as individual channels have grown. People aren’t switching from search to social. They’re adding social on top of search, TV, word-of-mouth, and brand websites, and using each for a different part of the decision.
Discovery And Intent Are Different Jobs
This is where the distinction between discovery and purchase intent becomes useful. Scrolling a social feed and stumbling across a product is a fundamentally different mental state to typing a specific query into a search engine because you’ve already decided you want something and now need to find or compare it. Social platforms are built for passive exposure, surfacing things a person wasn’t actively looking for. Search engines are built for active retrieval, answering a question the person has already formed. Both matter, but they sit at different points in the same journey rather than competing for the same moment.
Where AI Fits Into The Picture
The more interesting shift is what happens between those two moments. Increasingly, consumers are using AI assistants to bridge the gap, taking something they noticed on social media and asking an AI tool to help compare it against alternatives before they commit to a search or a purchase. That pattern gives shape to a simple framework: social creates the initial demand, AI increasingly intermediates the research and comparison that follows, and search remains where people go to find and complete the transaction once a decision has firmed up. Social makes someone want something. AI helps them decide what to actually buy. Search helps them find and buy it. None of the three replaces the others, they sit in sequence.
What This Means For Brand Strategy
The practical implication is that treating social and search as competing budget lines misses how consumers actually behave. A brand that only invests in social risks losing the moment when a browsing, undecided shopper becomes a searching, ready-to-buy one. A brand that only invests in search risks never entering the consideration set in the first place, since search only works once someone already knows roughly what they’re looking for. The GWI data reinforces this by age too, younger audiences discover through social first and search second, while older audiences do the reverse, meaning the balance between channels needs to reflect the audience rather than a single blanket strategy.
The Bigger Picture
None of this means one channel has “won” over another, and treating it as a zero-sum contest misreads what the data actually shows. Consumers are using more sources to discover and evaluate products than they were even two years ago, not fewer. For brands trying to build a coherent strategy across social, AI, and search, the more useful question isn’t which channel is growing fastest, but which job each channel is doing in the path between a scroll and a checkout. Getting that sequence right matters more than winning any single channel in isolation.
