For years, brands treated influence largely as a question of reach: find someone with an audience, place the product in their hands and amplify the message. That model is becoming less useful.

Today’s media landscape is fragmented across platforms, communities, interests and increasingly personalised feeds. Culture itself has fragmented with it. As WARC and TikTok observe, culture no longer simply flows from a small number of media gatekeepers; it increasingly emerges from creators and communities before travelling into the mainstream.

For brands, that makes cultural relevance more important — and harder to achieve through conventional media thinking alone.

Reach can tell us how many people saw something. Cultural relevance tells us whether it meant anything to them.

Research is beginning to quantify the difference. A WARC/TikTok study of social and video users aged 18–45 in the US, UK and Australia found that 58% were more likely to pay attention to an advertisement when it felt culturally relevant, while 56% said cultural relevance increased their willingness to purchase. More recent UK research from Newsworks found that cultural relevance contributed approximately 15% of sales across the four categories studied.

The implication is not that brands should chase every trend. In fact, that can achieve the opposite. Brands need to understand the communities they want to engage with and participate selectively, where there is a credible reason to do so.

This is where content creators have acquired a different kind of value.

The distinction is more than terminology. An influencer can offer access to an audience. A strong content creator brings something additional: an understanding of the language, humour, formats, behaviours and cultural codes of the community around them.

Creators are often close to cultural change because they participate in it rather than observe it from outside. They see which conversations are gaining momentum, understand why particular formats resonate and receive immediate feedback from their communities.

This is also changing the relationship between brands and audiences. Kantar argues that younger consumers are moving from passive consumption towards participation, with creators and peer networks increasingly shaping influence. In this model, creators can become co-authors of the brand story rather than simply endorsers of it.

That is an important shift. Brands are no longer simply borrowing someone’s distribution. They are accessing cultural knowledge.

This changes how brands should select partners.

Follower count, reach and engagement still matter, but they are incomplete measures. The more strategic questions are: Is this creator genuinely connected to the community we want to engage? Does their tone fit the brand? Do they understand the category? Is there a credible reason for this person to talk about us? And can they contribute creatively rather than simply execute a script?

There is a difference between hiring creators for reach and partnering with creators who are genuinely embedded in the culture a brand wants to enter. As creator marketing scales, that distinction becomes increasingly important: credibility, relevance and mutual value can easily be lost when creators are treated as another mass-reach channel.

Selection should start with cultural fit, not a follower leaderboard.

There is another contradiction brands need to resolve. A company may choose a creator because of their distinctive voice, community credibility and creative instinct — and then give them a brief so restrictive that all three disappear.

Effective creator partnerships require strategic boundaries, but also room for interpretation. Creators increasingly need to be treated not as media buys, but as partners bringing audience insight, creative point of view and cultural fluency.

The brand needs to be clear about the objective, values and non-negotiables. The creator needs enough freedom to translate the idea into the language of their audience.

That balance is what makes the difference between branded content that feels inserted into culture and work that genuinely belongs there.

Finding a creator is relatively easy. Building the right creator partnership is considerably harder.

It requires more than creator discovery. The agency must understand the brand and its commercial objectives, identify the cultural opportunity, distinguish meaningful signals from short-lived internet noise, and select creators for strategic rather than superficial fit. It then has to shape a brief that protects the brand without removing the creator’s ability to create.

Importantly, cultural intelligence cannot operate independently of brand and category knowledge. As recent WARC analysis argues, social and creator intelligence can show where culture is moving, but category expertise is required to determine which signals actually represent an opportunity for the brand.

This is where experienced agency orchestration becomes valuable: turning a creator appearance into a partnership with a clear reason to exist.

Because creators do not automatically make brands culturally relevant. Nor can relevance simply be bought through association.

It comes from choosing the right cultural space, understanding the people within it and creating something that contributes rather than interrupts.

In a fragmented media landscape, the brands that succeed will not necessarily be those appearing in the most feeds, but those that know where they have a credible role to play — and who can help them earn it.
