Your website is full of ghosts. They arrive without warning, drift through category pages and linger over products. Some even add items to their carts before disappearing without a trace.
No names. No follow-up. Just a suspicious amount of activity from anonymous website visitors your marketing stack apparently can't see. And with Halloween approaching, that's a particularly scary prospect.
Over the last decade, Halloween consumer spending has generally risen annually, in the U.S. topping a staggering $13.1BN in 2025 - a 12.9% surge on the previous year. Despite the frighteningly persistent economic headwinds haunting already stretched household budgets, forecasters expect consumers to spend more than ever this Halloween, with spending on candy, gifting, costumes, and decorations set to rise above 2025's record-breaking levels.
But Halloween isn't simply about selling costumes and candy during the final week of October. Consumers research, browse, compare prices, and return to products multiple times before purchasing. With Black Friday following less than a month later, every visitor represents potential value well beyond October 31.
The problem? Most retailers don't know who many of those visitors are.
Retailers invest heavily in attracting visitors through paid search, social, affiliates, and SEO, yet once those shoppers arrive, many effectively become invisible.
Traditional marketing platforms, including ESPs and CDPs, typically recognize only a fraction of website traffic. Consumers move between devices, browsers, and sessions without logging in, creating an identity gap between the audience retailers attract and the customers they can actually engage. And that's an expensive gap.
Someone viewing the same Halloween costume three times isn't displaying the same intent as somebody who immediately leaves. A shopper comparing decorations across several sessions is demonstrating interest. So is someone abandoning a cart after checking delivery options. Anonymous doesn't mean uninterested.
The behavior is there and the purchase intent is there. What's missing is the identity layer connecting those signals to a recognizable customer. That's where identity resolution changes the equation.
Recognizing visitors is only the beginning. The bigger opportunity comes from understanding what they're actually doing.
Imagine someone browsing Halloween decorations in September. Initially, they're gathering inspiration, two weeks later, they're comparing specific products and by mid-October, they've returned repeatedly and added items to their cart. Each interaction reveals something about purchase intent, but treating every visit identically ignores valuable context.
By connecting identity with real-time behavioral signals, retailers can deliver more relevant experiences throughout the purchasing journey.
That might mean:
The objective isn't sending more messages. It's delivering the right message, on the right channel, at the right time.
1. Look Beyond Conversion Rates
Conversion rates reveal what happened, but behavioral signals show what almost happened. Monitor repeat visits, product views, cart activity, and category engagement to identify shoppers demonstrating genuine interest, even when they don't immediately purchase.
2. Recognize Visitors Across Sessions
Customers rarely complete their purchasing journey in one visit. Identity resolution helps connect activity across sessions and devices, giving retailers a clearer understanding of customer intent and expanding their addressable audiences.
3. Make Email Behavior-Driven
Generic promotional blasts won't distinguish between somebody casually browsing and a shopper ready to purchase. Trigger personalized emails based on actual product interest, cart abandonment, and returning visits to engage consumers when they're most receptive.
4. Use SMS When Timing Matters
Don't simply duplicate email campaigns. SMS is particularly effective for time-sensitive reminders, shipping cutoffs, flash promotions, and inventory updates. Make every message useful, relevant, and timely.
5. Think Beyond Halloween
Someone discovering your brand while buying Halloween decorations doesn't disappear on November 1. Encourage email sign-ups, build first-party relationships, and use seasonal behavioral insights to inform more relevant campaigns throughout Black Friday, Cyber Monday, and the holidays.
For retailers, the biggest missed revenue opportunity isn't necessarily a lack of website traffic. It's the inability to recognize and engage enough of the shoppers already visiting.
Wunderkind's Autonomous Marketing Platform helps close that gap by combining identity resolution, real-time behavioral intelligence, and AI decisioning.
By recognizing 3–6x more digital traffic, Wunderkind helps brands expand their addressable audiences and determine the next best action for each shopper. And because AMP integrates directly with existing ESPs, SMS platforms, and other marketing tools, retailers can activate that intelligence without replacing their current technology.
The result is more relevant customer journeys and incremental revenue from traffic brands already have.
Halloween brings increased shopping activity, but the opportunity extends far beyond October 31.
The retailers that win won't necessarily be those sending the most promotions. They'll be the brands that recognize more visitors, understand their intent, and respond with relevant experiences while purchase interest is high.
Because your website isn't really haunted, your customers are already there, you just need to be able to see them.
