Halloween Retailers: 2026 UGC Boosts ROAS 4.1x

Halloween content, especially User-Generated Content (UGC), is a goldmine for retailers looking for real engagement and sales. As the digital space gets more crowded by 2026, authentic stories from actual customers will always beat manufactured campaigns because they build instant trust. So how does a retailer actually turn all that energy into a return they can measure? We pulled apart a 2025 campaign from “Costume Craze,” a mid-sized online costume shop, to see exactly what strategic moves led to their big win.

Campaign Teardown: Costume Craze’s “Spooktacular Style” 2025

Costume Craze (a fictional shop, but their model is solid) rolled out their “Spooktacular Style” campaign in September 2025. The goal was to get sales moving early and grab market share before the big-box stores drowned them out. Their entire strategy was built around getting customers to share costume ideas and creations, leaning into the fact that Halloween is an inherently social event. The campaign ran for a tight six weeks, from September 1st through October 15th.

Strategy: Cultivating Authenticity Through Community

Costume Craze’s main play was to get out of the way and shift from standard, brand-led seasonal marketing to a model driven by their own community. They knew that while their professional photos looked clean, a real customer’s grainy phone video resonates on a completely different level. As Sarah Jenkins, their Head of Digital Marketing, put it in a post-campaign interview, “People trust people. We wanted to tap into that peer-to-peer influence.”

The plan had a dead-simple call to action: customers submitted photos or short videos of their Halloween costumes (planned or already bought) with the hashtag #CostumeCraze2025. This wasn’t a passive “hope they post” effort. They pushed the hashtag hard in their emails and across social. The incentive structure was smart and tiered: just submit a photo and get a 10% discount code for a future purchase, but if you put in the effort to make a video, you were entered into a weekly drawing for a $100 store gift card. That tiered approach was the key move here, driving a much higher volume of video content, which almost always kills it on engagement.

Creative Approach: Real People, Real Fun

The campaign’s creative wasn’t polished at all, and that was the point. Instead of slick studio ads, Costume Craze’s feed and paid promotions were filled with actual customer photos. This meant they had to be comfortable with all kinds of different lighting, messy backgrounds, and quirky presentation styles. They just curated the best of what came in and plastered it on their homepage, product pages, and social feeds, prioritizing anything that was funny, creative, or just visually interesting.

For instance, one of their biggest hits was a 15-second TikTok of a family, parents and two kids, doing a clumsy dance in their matching superhero costumes. A customer posted it, Costume Craze reposted it on their official TikTok for Business account, and then they put money behind it as a paid ad. That one video brought in over 500,000 views and a 7.2% engagement rate, proving how much power there is in content that just feels real and relatable.

Targeting: From Broad Reach to Engaged Segments

Costume Craze’s paid targeting started broad, hitting general demographics on Meta platforms and TikTok who showed an interest in Halloween or parties. But as the campaign gathered data, they got much sharper. They built custom audiences from people who viewed specific costume categories on their site, their email subscribers, and (most importantly) users who had already liked, commented on, or shared one of their UGC posts.

They also layered in lookalike audiences built from their top 5% of converting customers from the previous Halloween. This strategy ensured that while their initial ads cast a wide net to build awareness, their later ad spend was laser-focused on warmer leads who were much closer to buying. They targeted nationwide in the U.S. but put a little extra budget into cities known for big Halloween celebrations.

Metrics and Performance: A Data-Driven Breakdown

Okay, the numbers. They put $75,000 into this over six weeks, with most of it going to paid social to promote both the call for submissions and the best UGC that came in. Here’s how it shook out:

• Total Impressions: 18.5 million
• Total Clicks: 310,000
• Overall Click-Through Rate (CTR): 1.68%
• Total Conversions (Purchases): 3,800
• Overall Conversion Rate: 1.23%
• Revenue Generated: $285,000
• Return on Ad Spend (ROAS): 3.8
• Cost Per Lead (CPL – defined as a UGC submission): $12.50 (they got 6,000 submissions against the budget that promoted the contest)
• Cost Per Conversion: $19.74

The most telling stat was the performance gap between their regular ads and the ads featuring UGC. Ads using customer photos and videos had an average CTR of 2.1%, while their traditional, polished product ads only managed a 1.3% CTR. That 61% lift in click-throughs made their entire media spend way more efficient.

And it gets better. The retargeting campaigns that showed UGC to people who’d already visited the site or engaged with their socials? That segment saw a massive CTR of 4.2% and delivered a ROAS of 5.5. It’s clear proof that using authentic social proof to close the deal with warm audiences is where the real money is.

What Worked: Authenticity and Iteration

It worked because it was real. Customers seeing other, normal people having fun with the products built a level of trust that a glossy ad just can’t buy. That tiered incentive system was a huge win, doing exactly what it was designed to do by pushing people to create video. And the data backs this up, a Statista report found that 79% of people say UGC heavily influences what they buy, which is exactly what Costume Craze saw in their results.

They also ran a tight A/B testing process, constantly tweaking their calls to action, ad copy, and audience segments. This meant they could shift budget away from things that weren’t working and double down on the high-performing stuff mid-campaign.

Using an AI analytics tool, something like Sprinklr’s social listening, let them spot trends in the UGC as they happened. For instance, they saw a spike in “retro 80s” costume submissions and immediately spun up a new ad set promoting their 80s products, using the customer content they’d just received. Being that agile and responsive to what customers are actually into is a massive advantage.

What Didn’t Work (Initially) and Optimization Steps

Of course, it wasn’t all perfect from the jump. In the first week, just asking for submissions brought in a ton of blurry photos and posts that had nothing to do with costumes. So they optimized. They quickly updated their submission page with clear guidelines and even posted examples of what a “good” photo or video looked like (think good lighting, clear shot of the costume). They also created a simple “quality score” for their internal team to use, which helped make sure only the good stuff got promoted.

The volume of submissions also became a problem. The incentives worked, but their team was getting buried trying to review everything manually. They solved this by setting up some basic automated filters that could check for keywords and even detect if an image actually had a person in a costume. This simple step cut the manual review workload by 30%, freeing up their team to focus on curating great content instead of just filtering junk.

They also learned that just reposting a customer’s video without adding any context didn’t perform as well. The fix was to add specific product tags to their Instagram reposts, include direct links to product pages in their promoted TikToks, and write short, punchy captions that actually sold the costume. It’s a good reminder that even authentic content needs to be tied back to a commercial goal.

Editorial Aside: The Unseen Value of Authenticity

I see so many retailers get hung up on losing control with UGC. They’re worried about off-brand posts or stuff that looks amateurish. My take? Get over it. The slight imperfection of UGC *is* its greatest strength. It’s a signal of authenticity, which is a rare and valuable commodity when everyone is tired of perfectly curated brand messages. The “risk” of a slightly less polished photo is tiny compared to the trust and connection it builds. Any retailer who tries to over-manage their UGC program is missing the entire point. The magic happens when you let your community take the lead.

This is right in line with the big shift toward brand advocacy, where building genuine trust is more valuable than just throwing discounts at people. And the speed at which Costume Craze could deploy and analyze content is the same skill set needed for effective breaking news campaigns. Their smart use of AI for campaign decisions was also obviously a huge factor in letting them move that fast.

Conclusion

Costume Craze’s “Spooktacular Style” campaign is a great playbook for how a well-run UGC strategy can fatten a retailer’s bottom line during a peak season. They focused on real customer content, gave people a clear reason to participate, and used data to optimize everything on the fly, which led to a fantastic ROAS and a more loyal customer base. The lesson for other retailers is to make it easy for customers to submit content and then get ready to put real ad dollars behind the best stuff that comes in.
