So, here we are. If you’ve been running a Shopify store for more than a minute, you know the drill: the constant scramble for better ad performance in an era where privacy laws make targeting feel like throwing darts in a pitch-black room. The Shopify Audiences update October 2025 just dropped, and honestly? It’s a lot to take in. Some folks are calling it a game-changer for customer acquisition costs. Others are just trying to figure out if it’s worth the Shopify Plus price tag.
Let’s get real.
Shopify Audiences has always been that "secret sauce" for Plus merchants—a way to use the platform's massive pool of aggregate data to find people who actually want to buy stuff. But the October 2025 tweaks have pushed things into a new territory, specifically focusing on how the platform handles "Retargeting Boost" lists and the sheer scale of the machine learning behind the scenes.

The Big Shift: Audiences v2.4 is Here
Basically, the headliner of the Shopify Audiences update October 2025 is the transition to version 2.4 of their proprietary algorithms. If you're tired of hearing about "AI-powered everything," I get it. But here, the numbers are actually doing the talking.
According to internal Shopify data, merchants using the latest version of Retargeting Boost lists are seeing up to 2 times more orders for every dollar spent on retargeting compared to other tactics. That’s a massive claim. Usually, when a platform says "2x," we take it with a grain of salt, but the logic here is sound: Shopify is looking at real purchase intent across millions of stores, not just clicks or "likes."
Why this matters right now
Privacy is a headache. With Meta and Google constantly adjusting their tracking because of iOS 14+ and the slow death of cookies, first-party data is king.
Shopify is essentially saying, "We have the best first-party data in the world, and we're going to let you use a hashed version of it to find your next customer." In this October update, they've refined the Existing Customers Plus exclusion list. On average, it’s now excluding 40% more existing customers than previous versions. Why do you care? Because you stop wasting money showing ads to people who already bought your product yesterday.
The "Unlisted" Strategy: A Stealthy New Addition
While not strictly an "Audience" tool in the traditional marketing sense, the new Unlisted product status introduced in October 2025 is a weirdly perfect companion for high-intent targeting.
Imagine this: You use Shopify Audiences to identify a high-value segment of "VIP-likely" buyers. You want to send them to a page for a product that doesn't officially exist on your site. You don't want it in search results. You don't want it in collections. You just want those specific people to see it.
The "Unlisted" status makes this possible. The product is active and purchasable, but only via direct URL. It’s perfect for:
- Private "thank you" offers for a specific audience segment.
- Warranty replacements that shouldn't clutter your catalog.
- Hidden "add-on" items for specific ad campaigns.
Cutting Costs: The 50% CAC Goal
Let's talk money. Nobody runs ads for fun.
The Shopify Audiences update October 2025 claims it can help cut customer acquisition costs (CAC) by up to 50%. How? By getting way more surgical with lookalike models. Instead of a broad "people who like yoga," Shopify’s v2.4 algorithm identifies "people who have actually purchased a $100 yoga mat in the last 30 days."
It’s the difference between targeting a window shopper and targeting someone with their wallet already open.
Breaking Down the Ad Platforms
Shopify isn't keeping this in a silo. The October update strengthens integrations across:
- Meta (Facebook & Instagram): Better syncing for Advantage+ campaigns.
- Google: Improved Performance Max (PMax) signal sharing.
- TikTok: Faster audience refreshing for those viral moments.
- Snapchat, Pinterest, and Criteo: Expanded support for niche merchants.
Benchmarking: How Do You Actually Stack Up?
One of the coolest (and most underutilized) parts of the Shopify Audiences update October 2025 is the enhanced benchmark data. Honestly, most merchants are flying blind. They see a 2% conversion rate and think, "Is that good?"
Now, you can see how your ad performance stacks up against stores with similar order values and products. If the industry average for beauty and wellness is hitting 6.8% CVR (which is a real 2025 benchmark) and you're sitting at 2%, you know it’s not the audience—it’s your landing page.

The Logistics Problem: It’s Not Just About the Ad
You can have the best audience in the world, but if your checkout sucks, you’re burning cash.
The October updates also touched on B2B order reviews. If you’re a Plus merchant using Audiences to drive wholesale leads, you can now trigger manual reviews for orders based on custom rules—like fresh accounts or unusual order volumes. It’s a safety net. You find the lead with Audiences, you close the deal with B2B tools, and you protect your margin with the review system.
Minute-Level Analytics
If you’re running a flash sale to a Shopify Audience list, the new minute-level resolution in Shopify Analytics is your best friend. You can see the exact second the traffic spikes and, more importantly, when it starts to tail off. No more waiting until the next day to see if your "early bird" email actually worked.
Actionable Steps: What to Do Monday Morning
Don't just read this and go back to your coffee. If you're on Shopify Plus, here is the immediate plan to leverage the Shopify Audiences update October 2025:
Step 1: Refresh Your Lists.
Go into the Audiences app and make sure you’re using the v2.4 Retargeting Boost lists. If you haven't refreshed your export to Meta or Google in a few weeks, do it now. The new algorithm needs to sync to be effective.
Step 2: Tighten Your Exclusions.
Enable the Existing Customers Plus exclusion list. Stop paying for clicks from people who are already on your email list or have an open order. That 40% improvement in exclusion accuracy is low-hanging fruit for your ROAS.
Step 3: Test the "Unlisted" Funnel.
Create an "Unlisted" product with a special offer. Build a custom audience in Shopify Audiences of people who haven't bought in 60 days. Run a small, targeted ad campaign directly to that hidden URL. It’s a clean way to test "VIP" offers without devaluing your brand for everyone else.
Step 4: Check the Benchmarks.
Look at the new comparison data in your dashboard. If your "Cost per Purchase" is significantly higher than similar stores in your industry, it’s time to look at your creative. Shopify is giving you the right people; it’s your job to give them the right message.
The reality of 2026 e-commerce is that the "spray and pray" method of advertising is dead. You either use the data or you get out-spent by someone who does. The October 2025 update isn't a magic wand, but it’s a much sharper scalpel for merchants who know how to use it.
