Audience strategy is where most Meta campaigns are won or lost before a single ad is served. Fashion brands that understand this consistently outperform those treating audience selection as a secondary concern.
The Broad vs Narrow Debate
For years, the instinct in fashion advertising was to narrow the audience tightly. Women, 25-45, interested in luxury fashion, in major cities. The logic seemed sound: targeted audience, relevant creative, lower waste.
Meta's algorithm changed the calculus. In 2026, overly narrow audiences often perform worse than broader ones because they constrain Meta's ability to find the buyers it would otherwise discover on its own. The platform has more behavioural data than any interest or demographic targeting a human can construct.
But broad targeting is not the same as no strategy. It's a different strategy — one that puts more weight on the creative to do the qualifying, rather than the audience parameters.
What Strong Audience Strategy Actually Means
For fashion brands, strong audience strategy means understanding the relationship between cold audiences, custom audiences, and lookalikes — and knowing how to weight spend across them at different funnel stages.
It means knowing whose data you're building on and whether that data is clean. It means understanding when to let Meta find your buyers and when to constrain it. It means reading the signals the account is producing and adjusting accordingly.
None of this is set-and-forget. It's an ongoing discipline.
