The brief01

Laundry detergent is the definition of a low-interest category on social media.

Persil needed to generate engaging TikTok and Instagram content for a product that people use daily but never talk about. The challenge: making laundry exciting without being cringeworthy.

The idea02

We deployed a dark posting campaign with carefully selected UGC creators.

The key: creators who could make everyday moments entertaining. Script writing ensured brand messaging landed naturally. Dark posting allowed testing 10+ creative variations without cluttering Persil's main feed. Performance analysis optimized each wave of content. The insight: let the algorithm find your audience through multiple creative lenses rather than one "perfect" ad.

What we did
  1. 01
    Dark Posting Strategy

    10+ creative variations tested via dark posts — invisible on the main feed but visible to targeted audiences.

  2. 02
    Script-Driven UGC

    Carefully written scripts ensured brand messaging landed naturally — the creator's voice, the brand's message.

  3. 03
    Everyday Moment Creators

    Creators who make daily routines entertaining — laundry becomes content when the right person tells the story.

  4. 04
    Algorithm-Driven Targeting

    Multiple creative lenses let the algorithm find the best audience per variant — quantity enables quality in paid social.

What mattered

Dark posting lets you test 10+ creative variations without cluttering the brand feed.

The algorithm finds your audience better than you can target them.
