TikTok trends fade within five days: how brands can make the moment last

A new study from Publicis Groupe APAC and TikTok has found that TikTok trends move at extraordinary speed, with the median trend lifespan now just five days. Only 27% of TikTok trends sustain relevance beyond two weeks, which means that by the time many brands spot, approve and produce content around a trend, the moment may already have passed.

However, the research also shows that not all trends disappear quickly. The ones that last tend to share three characteristics: they tap into a shared human emotion, they are easy to remix, and they are created with creators rather than dictated by brands.

This is an important distinction for advertisers. TikTok is not a traditional broadcast channel where brands can simply push out a message and expect it to land. The trends that travel furthest are often built around simple formats: visual templates, adaptable sounds, easy actions or repeatable mechanics. In other words, formats travel better than messages.

For brands, this means success is less about chasing every trending moment and more about creating ideas that people can participate in. A brand does not always need to “own” the conversation. Often, the stronger role is to create the conditions for audiences and creators to make the idea their own.

Creative freedom is also critical. Creators are powerful because audiences trust their voice, so brands need to set clear guardrails rather than hand over rigid scripts. On TikTok especially, over-polished or over-controlled content can feel out of place. Creator-led ideas are more likely to feel native to the platform, and more likely to be remixed by others.

Implications for Ireland

For Ireland, this reinforces the need to think about TikTok trends through both a global and local lens. A trend may travel quickly across markets, but it still needs to make sense within Irish culture to feel credible.

Irish humour, language, local occasions, communities and everyday behaviours can all shape whether a trend feels natural or forced. The opportunity is not simply to copy what is trending elsewhere, but to adapt the format in a way that feels relevant to Irish audiences.

This is particularly important because trends move faster than many campaign approval processes. If a brand wants to engage with TikTok culture in Ireland, it needs the ability to respond quickly, while still staying true to its tone of voice and brand guidelines.

‍ ‍What this means for Irish advertisers

For Irish advertisers, the key learning is that TikTok rewards participation over perfection. Brands should focus less on chasing every trend once it is already peaking, and more on building simple, creator-led formats that are emotionally relatable, easy to remix and locally relevant. For many brands, the opportunity may not be to produce more content, but to produce content that is more adaptable.

This also reinforces a key point from Core’s Digital Trends report: fit beats fame. The most effective creator is not always the biggest one, but the one who genuinely aligns with the audience, the brand and the cultural moment. On TikTok, that alignment matters because creator content needs to feel native, credible and easy for others to build on.

TikTok trends may have a five-day shelf life, but strong formats can last longer when they are built for remixing, creator collaboration and local relevance. For Irish advertisers, the priority should be to build ideas people can participate in, not just messages they are expected to watch.
