The question behind this article

“How can brands connect better with diverse audiences, like women’s football fans, through personalised advertising?”

Short answerBy personalising for context and culture before tracking. Niche audiences such as women’s football fans reward brands that show they understand their world: their heroes, their language and their gripes. You get there by listening to what they post, building variants for each group and testing which creative works before you spend. Trust is the precondition, not a side effect.

Key takeaways

  • The personalisation that works today adapts to the audience’s community and moment, not to each person’s browsing history.
  • Personalisation is an exchange of attention and data for relevance; if the audience feels the deal is unfair, trust breaks for the campaigns that follow as well.
  • In niches such as women’s football, a single age bracket can hide very different tensions that call for different messages, tones and channels.
  • SAMY’s acquisition of Get Engaged, reported by El Publicista, confirms that the market is betting on connecting through creators and culture.
  • Testing creative variants before media spend turns the results conversation with the client into a conversation about evidence.

How can a brand connect with diverse audiences, such as women’s football fans, through personalised advertising? By personalising for context and culture before tracking. Niche communities reward brands that show they understand their world, and punish the ones that only turn up when there’s a final. Technique matters, but trust comes first.

The market is saying so with its chequebook. According to El Publicista, SAMY, the Spanish-born, Bridgepoint-backed social-first agency, has bought Get Engaged, a US agency specialising in creators, talent, entertainment and culture. Get Engaged co-founder Cam Fordham sums up the thesis: the future of marketing belongs to brands that can create moments people want to be part of. (Disclosure: SAMY is a Defy client.)

Look closely at that line. It isn’t about reaching each person with their name in the ad. It’s about earning a place in something people already care about. That’s the personalisation that works in 2026.

What does personalising advertising mean today?

For years, personalisation meant stalking: following someone around the web and showing them the trainers they looked at yesterday. That model depends on third-party data that’s ever scarcer, pricier and more regulated, and it triggers a recoil everyone recognises in themselves.

The alternative isn’t to stop personalising. It’s to change the foundations. Instead of adapting the ad to what you know about one person, you adapt it to the community they belong to, the moment they’re in and what that community says in public. Less surveillance, more understanding.

Why does badly done personalisation destroy engagement?

Trust Theory, in its economic form, gives the most useful explanation: trust is what makes exchanges cheaper. When you trust someone, you don’t need to watch them, check everything or protect yourself. When you don’t, every interaction costs more.

Personalisation is an exchange. The audience hands over attention and, sometimes, data; in return it expects relevance. If people feel the brand knows too much, or is only using them to sell, the deal breaks. And it doesn’t break just for that campaign. It breaks for the ones that follow.

That’s why trust is the soil in which engagement grows. It isn’t a side effect of a good campaign; it’s the condition for there being a campaign at all. In niche communities, where everyone knows everyone and opportunism is spotted instantly, the margin for error is even smaller.

The women’s football case: a niche that doesn’t forgive opportunists

Take a hypothetical example. A sports drinks brand wants to reach women’s football fans in Spain or Latin America. The lazy approach would be to target “women, 18–35, interested in football” and launch a single ad fronted by a famous player.

Now suppose that, before buying any media, the agency listens to what that community posts and finds three groups:

  • Lifelong club supporters, who complain about shifting kick-off times and broadcasts that are hard to find.
  • Grassroots players, who want relatable role models and kit designed for them.
  • Newer fans, who arrived via the national team and follow specific players on social.

Three different tensions, three different personalisations. For the first group, the brand can be useful by helping them follow the matches. For the second, it can talk about football as they actually play it, not just the elite game. For the third, the creators and players they already follow are the natural channel. None of this requires knowing who each individual is; it requires understanding each group.

How to personalise ads for a niche audience, step by step

  1. Listen to the community in its own spaces. Social platforms, forums, match-day comment threads, fan accounts. Before you speak, learn how they speak.
  2. Cluster what you find into personas and tensions. Not by age, but by the problem or desire they share.
  3. Work out what the brand can bring. If the answer is “nothing, we just want visibility”, the community will notice. Find a useful role.
  4. Build variants for each tension, with voices from the community. Same idea, different tone, different references. Creators who genuinely belong to the niche bring a credibility that media money can’t buy.
  5. Test the variants before you spend. With several versions per group, guessing which will work gets expensive. Defy, for example, scores each creative’s likelihood of being clicked before media spend, with predictions validated against real ad performance, so the results conversation with the client starts from evidence rather than gut feel.
  6. Activate with first-party data and context. The advertiser’s own audiences, the media and environments where the community already is, and the calendar moments it cares about.
  7. Measure by group and give value back. Split results by tension and check whether the community is responding or drifting away. Trust can be measured too.

Can you personalise at scale without losing authenticity?

That’s the question behind SAMY’s deal. According to El Publicista, the acquisition follows wins of the Unilever Foods and Barilla global accounts, and CEO Juan Andrés Elhazaz Walsh says the combination “consolidates SAMY as a global leader in scalable social and influencer marketing operating models”. Alex Dermer, CEO of Get Engaged, explains that his agency was founded to help brands connect with culture in ways that drive business.

Scale and culture look as if they pull in opposite directions, but they needn’t. What doesn’t scale is improvising every piece. What does scale is a method: listen, cluster, build variants and test them before you pay. People and communities supply the authenticity; the system stops every campaign starting from scratch.

What should brands ask their agency?

If you’re an advertiser about to invest in personalisation for a niche, four questions separate a serious proposal from a punt:

  • Where do the personas and tensions you’re showing me come from? Can I see real examples?
  • What does the brand give that community, beyond visibility?
  • How will you choose between variants before spending the media budget?
  • How will you measure whether the community trusts the brand more or less after the campaign?

An agency that answers all four with evidence isn’t selling you personalisation. It’s selling you understanding, which is what makes personalisation work in the first place.

Frequently asked questions

Can you run personalised advertising without third-party cookies?

Yes. Community and context personalisation doesn’t need to follow each person around the web. It relies on the advertiser’s first-party data, the environment where the ad appears and what communities publish openly. It takes more understanding work up front, but it depends less on external sources and generates less pushback from the audience.

What’s the difference between targeting and personalising?

Targeting is deciding who sees an ad. Personalising is adapting what you say so it makes sense in their context. You can target with great precision and still show a generic message. With niche audiences, what makes the difference is adapting the message, the tone and the cultural references to each group.

How do I know if personalisation feels invasive?

A simple test: if the ad reveals something the person doesn’t remember sharing with the brand, it will feel invasive. If it reflects something the community says in public, such as its heroes or its complaints, it tends to read as understanding. When in doubt, explain why the person is seeing the ad and offer something useful in return.

Is it worth working with creators in niches like women’s football?

It usually is when the creator genuinely belongs to the community and has the freedom to adapt the message. They bring language, credibility and context that take a brand years to earn. SAMY’s acquisition of Get Engaged, which specialises in creators and culture, points in that direction. Measure their contribution by the same criteria as the rest of the plan.
