What works best is not forcing this into the traditional "work experience" structure. Instead, create a specific section called something like "Digital Projects," "Online Presence," or straight-up "Content Creator." That way you make it clear from the start that it's not a conventional job, but you give it the weight it deserves.
Within that section detail real numbers and results: how many followers you accumulated, what type of content you created (frequency, topics), what those brand collaborations were and what impact they had. If any collaboration generated sales, reach, or measurable visibility for the brand, include it. That's what recruiters care about.
The pitfall here is staying vague. "I have followers" doesn't say anything; "5,000+ TikTok followers with [topic] content, collaborations with brands in [sector]" does communicate that you know how to produce content, that you understand algorithms, and that brands trust you. If you did something specific like manage an editorial line, negotiate with brands, or analyze metrics, mention that too. Recruiters know that a creator with a track record of collaborations has negotiation, communication, and project management skills, even if you didn't get a fixed salary.
