Sales data is one of the clearest signals retailers can use to refine their product assortment strategies, yet it’s still underutilized. Retailers may look at their sales from six months ago and rely on their gut instinct to make product assortment decisions.
However, they are missing out on the real-time sales data that shows what is trending and what consumers are buying at the moment. On TikTok Shop, where trends shift overnight, the numbers tell a story of real-time sales that no gut instinct can match.
Retailers who pay attention to this data don’t need to be selling on TikTok Shop themselves to benefit. If blush sales spike on TikTok, that’s a cue beauty retailers should stock more blush across their own shelves and channels. The same applies across categories; when TikTok shoppers signal momentum, it’s a strong indicator of what will move in-store and online elsewhere.
Hashtags as Real-Time Demand Signals
Hashtags are direct demand signals, showing what shoppers are actively searching for and buying. For example, on TikTok Shop, beauty categories fueled by tags like #koreanskincare and #hairtok show just how quickly niches can scale into major sales drivers. A hashtag that gains traction today often translates into higher demand tomorrow, both online and in-store.
With Charm data, you can see beyond which hashtags are trending to understand which hashtags are driving sales for certain brands and products. Take #koreanskincare, which from August 2024 to August 2025 generated 445M views and $8M in revenue. Its top product, the Dr.Melaxin Official Peel Shot Glow Rice Ampoule Duo, alone captured 116M views and $1.9M in sales associated with the hashtag. Those numbers reveal how quickly a single category signal can move from niche interest to mainstream momentum.
As for #hairtok, with 337M views and $4M in revenue over the same period. The standout item, the Wavytalk Blowout Boost Ionic Thermal Brush, pulled in 30M views and $367K in revenue associated with the hashtag. These spikes illustrate how consumer engagement directly translates into product opportunities.
When #koreanskincare generates a surge in engagement, it’s a strong prompt to prioritize serums, toners, and Korean skincare essences. As #hairtok dominates, expect styling tools, treatments, and accessories to follow the same upward curve. Aligning assortments with what shoppers are already talking about helps ensure shelves reflect real-time consumer desires, not yesterday’s trends.
Stop Guessing and Let the Data Show You What to Stock
TikTok Shop is not built for passive sellers. It rewards speed, accuracy, and timing. A single viral moment can clear out your inventory in a day, while slow movers vanish from visibility. That’s why sales data is your most valuable resource. It tells you exactly what’s gaining traction, what’s starting to lose momentum, and what’s not landing with shoppers at all.
With this data in hand, you can:
- Align your product assortment with emerging trends before they peak
- Quickly cut products that aren’t converting
- Rethink positioning, pricing, or bundling before it starts costing you revenue
Relying only on your own store’s sales metrics limits your view. You might know what’s working inside your shop, but without platform-wide visibility, you’re missing broader buying patterns. Leading retailers aren’t just tracking their own numbers. They’re watching category trends, creator-driven lifts, and cross-shop momentum to sharpen their entire merchandising strategy.
Think of data not as a rearview mirror, but as a real-time radar. It tells you where shoppers are headed, not just where they’ve been.
Find White Space Gaps and Opportunities in Your Assortment
Analyzing sales data also helps identify what’s missing. Maybe your catalog is too concentrated in one category. Maybe you're missing a high-demand color, size, or price point. Data on the category, shop, and product level lets you spot these gaps and act before they cost you sales.
This doesn’t just help with inventory planning, it impacts how you source, how you price, and how you tell product stories through content and creators. Every SKU in your store should be there for a reason, backed by data that proves it has demand.
Use Performance Trends to Guide Product Development
Sales data isn’t just a rearview mirror. It’s a preview of what your next product should be. Retailers analyzing sales data across TikTok Shop can spot emerging patterns, like ingredients that keep showing up in top sellers or styles that are trending across brands.
Retailers can also leverage Charm.io to broaden their view beyond individual products and gain insights across entire brand landscapes. This helps them make smarter merchandising decisions and identify future bestsellers and potential supplier leads before their competitors do.
With TikTok Shop data, retailers can track:
- Hashtag trends to identify emerging cultural moments and product opportunities before they peak.
- Creator-level performance to understand which influencers are truly driving conversions and what content is driving conversions.
- Top-selling categories, shops, and products to see what’s moving the needle right now.
Charm data can guide you, helping you launch SKUs that are aligned with demand from the start. No more guessing if something will work. You’ll already know it can, because the data told you.
Data-Backed Merchandising Beats Instinct Every Time
Merchandising by gut might have worked in the past. But on a platform as reactive as TikTok Shop, that approach is outdated. Analyzing sales data ensures that every item in your assortment serves a purpose. It tells you what to lead with, what to discount, and what to double down on.
You’re no longer throwing products at the algorithm and hoping something sticks. You’re creating a strategy that mirrors what shoppers are already looking for.
Make Sales Data Your Merchandising Edge
Analyzing sales data doesn’t just tell you what happened, it gives you the insight to shape what happens next. If you’re not using TikTok Shop data to inform your assortment, you’re missing one of the clearest signals in ecommerce today.
Retailers that succeed on TikTok are the ones who stay close to the numbers and even closer to their audience behavior.
