From costumes to conversions—Partyking wins sales with Pinterest Performance+

Goal

Partyking is a go-to for costumes and party supplies in Sweden—but with a niche offering, a more local audience, and growing competition, they wanted their advertising to work harder and smarter.

Always open to new tools and approaches, the team was actively looking for innovative ways to scale their reach and expand their customer base. Pinterest stood out as the perfect fit. With Pinners constantly in planning mode—turning to the platform to prepare for everything from big celebrations to everyday moments—and Pinterest Performance+ built to meet that intent with automation and efficiency, it offered a timely, budget-friendly way to capture attention.

In collaboration with their agency AdRelevance, Partyking set out to win shoppers looking for celebratory products—with an overarching goal to drive stronger performance, profitability and relevancy ahead of the peak retail season.

Strategy

To get ahead of the seasonal rush, Partyking launched their campaign in early September—eight weeks before Halloween, when planning was already in full swing. By showing up early, they placed themselves at the centre of the moment—becoming part of the celebration before plans were finalised and purchases made. With Pinners known for being intentional and early planners, the brand built its campaign around this mindset, delivering content tailored to every stage of the journey—from inspiration to action.

Pinterest Performance+ made it easy to do just that. As part of their media strategy, Partyking leaned into Pinterest’s automated solution to remove the heavy lifting of manual targeting and help unlock full-funnel reach with greater efficiency. Audience insights showed that 89% of their Pinterest users were interested in categories like Art, Home Decor, DIY and Crafts, Event Planning and Entertainment—with Event Planning ranking in the top five for affinity. It confirmed that Pinterest was the ideal place to connect with a relevant, high-intent audience at scale.

Creatively, Partyking brought the fun. With a mix of humorous, inspirational and lifestyle-led assets, they delivered scroll-stopping, feel-good content that captured the joy of every occasion. Using both Static Image ads and Carousels, they showcased a variety of celebration-ready ideas—all crafted to meet the moment.

Results

The results were definitely worth celebrating. In just three weeks, checkouts popped off, ad spend dropped, and orders flooded in. Pinterest Performance+ helped Partyking drive a 55% spike in checkouts, cut cost per click by 46%, and boost both return on ad spend and total orders by over 40%.¹ Proof that early engagement on Pinterest can unlock powerful results—especially when intent is high and the timing is right.

Encouraged by the impact, Partyking has since doubled down on Pinterest Performance+—proving that with the right creative, the right timing, and the right platform, even the most niche brands can scale with impact and effectiveness.

By leaning into automation and aligning with how people discover, plan, and shop on Pinterest, Partyking turned seasonal moments into measurable performance—and set the stage for continued growth.
