7 digital campaign ideas to celebrate the Diada with authenticity

11 September is a date loaded with symbolism. It is also an opportunity for brands. But making the most of the Diada doesn't mean posting a senyera on Instagram and adding a “Bona Diada”. Running a meaningful campaign goes much further than that.

The key is finding an idea that connects with the brand's values. And that also has something to say.

Participation, culture, territory and creativity can become great allies. In fact, this year's 2026 institutional campaign, “Tot allò que ens uneix” (Everything that unites us), puts the focus on identity, plurality and coexistence. That's why, at acrōnim, we propose 7 digital campaign ideas to celebrate the Diada with authenticity.

What does Catalonia mean to you?

This can be the campaign's central question.

The brand invites its community to answer with a photo, a video or a sentence. The best answers can become social media content. The result is a campaign built on real stories. Not corporate messages.

Eleven people. Eleven stories. One date.

The campaign can give a voice to people of different ages, professions and backgrounds. Each one explains what the Diada means to them. It can become a series of Reels, short interviews or blog pieces. As well as generating content, this idea shows a diverse, present-day Catalonia.

A digital campaign can also put the territory centre stage. The idea is to create an interactive map with recommendations from the community. A village. A restaurant. A local festival. A landscape. A special place.

Users can share their favourite corner of Catalonia using a hashtag created for the campaign. It's a good option for brands linked to tourism, food or local retail.

Tradition can be reinterpreted too. A brand can invite artists, designers or users to create their own graphic version of the four bars.

The different proposals can then form a digital gallery. This idea turns the campaign into a participatory experience. And it lets you build a visual universe of your own.

Gamification is another possibility. A quiz on Catalan culture, food, music or trivia can drive participation and engagement.

It can run on Instagram Stories, a landing page or a web app. A prize or incentive can be added too. But it shouldn't be the only reason to take part. The experience has to be worthwhile in itself.

The Diada can also be used to give visibility to local businesses. A brand can create a digital guide to local shops. It can also partner with other Catalan companies and create cross-promotional content.

This kind of campaign connects territory, community and brand. It's an especially interesting formula when the company's value proposition is tied to proximity or local consumption.

What if we did something different this year? Instead of repeating the same symbols and messages, a campaign can ask what Catalonia is like today.

Different people. New habits. New ways of creating. New projects. New ways of understanding the territory. The idea is to build a contemporary campaign. With its own visual identity and a concept that can adapt to different channels.

Because a good campaign is not just a post. It's an idea that works across social media, web, advertising and other touchpoints.

The seven ideas have one thing in common: the idea must come before the channel.

First we need to define what we want to communicate. Then, to whom. And finally, how we'll do it.

acrōnim works from exactly this perspective. Strategy, branding and digital marketing are all part of the same way of understanding communication.

Communication works better when it has a purpose.

So this Diada, your brand doesn't need to say more. It needs to say something that makes sense.

And that people want to hear.
