Here’s how brands can activate Cannes strategically:

Cast Creators With Event Credibility

Use an influencer discovery platform to find creators who have proven engagement around high-profile events like Cannes, Fashion Week, or brand activations. Prioritize influencers with a track record of red carpet attendance, styling partnerships, or festival coverage to ensure relevancy and resonance.

Track in Real Time

Leverage influencer tracking tools to monitor content performance as campaigns unfold. With Cannes unfolding over several days, being able to optimize creator output based on live metrics like EMV, views, and engagement rate is critical for maximizing ROI.

Build Long-Term Collaborations

Cannes isn’t just about one night, it’s about establishing long-term visibility. Use Cannes as a kickoff for year-long ambassador programs or multi-event campaigns that extend beyond the red carpet. Influencers who carry your brand throughout the year drive greater trust and consistency.
