Social commerce generates demand. Performance marketing scales it efficiently — and tells you exactly what it costs to acquire each customer. This is where art meets arithmetic.
Most brands think about ads backwards. They start with “how do I spend more on ads to get more sales?” The better question — the one the brands we work with learn to ask — is “what is each customer actually costing me to acquire, and is that customer worth more than that over their lifetime?”
That reframe changes everything. It turns advertising from a slot machine into a system. And in a region where platform economics are tightening every year (more on that in Chapter 6), running ads as a disciplined system rather than a hopeful gamble is the difference between scaling profitably and scaling yourself into a hole.
This chapter covers the ad ecosystems across Shopee, Lazada, TikTok Shop, and Meta; how to think about the full funnel rather than just bottom-of-funnel conversion; the specific tactics that have driven real results for our clients; and the strategic question every operator now faces — how much of your advertising to hand over to the platforms’ AI.
Performance marketing in SEA eCommerce splits into two distinct layers, and understanding the difference is foundational.
In-marketplace ads run inside Shopee, Lazada, and TikTok Shop. They target buyers who are already on the platform, already in shopping mode. These are your search ads, product ads, and live ads — capturing intent that already exists. The buyer is close to the bottom of the funnel; your job is to win the click and the conversion.
Off-platform ads run on Meta (Facebook/Instagram), Google, and TikTok’s broader ad ecosystem. They reach buyers who aren’t currently shopping — building awareness, creating demand, and driving traffic into your marketplace listings or DTC store. The buyer is higher in the funnel; your job is to create or capture interest and route it to a place where it converts.
The brands that win run both layers in a coordinated way. In-marketplace ads alone means you’re only ever competing for existing demand — you’ll plateau when you’ve captured your share of it. Off-platform alone means you’re generating interest but may be leaking it if your marketplace listings aren’t optimized to convert (which is why Chapter 3 came first). Together, they compound.
| ad system | layer | What It does |
|---|---|---|
| Shopee Ads | In-marketplace | Search ads (keyword-targeted), product/discovery ads, and Shopee Live ads. The core engine for capturing search-driven intent on Shopee. |
| Lazada Sponsored Solutions | In-marketplace | Sponsored Search, Sponsored Discovery, and Sponsored Affiliate. Lazada's suite for visibility within the platform. |
| TikTok Shop Ads / GMV Max | In-marketplace + discovery | Video Shopping Ads, LIVE Shopping Ads, Product Shopping Ads, and the AI-driven GMV Max that automates targeting and bidding toward a GMV goal. |
| Meta CPASs | Off-platform → marketplace | Collaborative Ads — Facebook/Instagram ads that link directly to your Shopee or Lazada listings, blending Meta's targeting with marketplace conversion. |
| Meta (standard)) | Off-platform → DTC | Standard Facebook/Instagram ads driving traffic to your own DTC store, where you own the customer data and the full margin. |
| Google / YouTube | Off-platform | Search intent capture (Google) and awareness (YouTube). Often underused in SEA eCommerce but valuable for high-consideration categories. |
CPAS – THE SEA WORKHORSE
Meta Collaborative Ads (CPAS) deserve special mention because they’re one of the most effective tools in the SEA marketplace operator’s kit. They let you run Facebook and Instagram ads that click straight through to your Shopee or Lazada listing — combining Meta’s powerful targeting with the conversion strength of a marketplace listing that already has reviews, ranking, and trust signals.
For brands selling primarily on marketplaces, CPAS is often the single most important off-platform channel. We’ll show you a real example of geo-targeted CPAS shortly.
The most common performance marketing mistake we see is brands pouring their entire budget into bottom-of-funnel conversion ads — retargeting, branded search, high-intent keywords — and wondering why growth stalls.
Bottom-of-funnel ads are efficient because they harvest demand that already exists. But there’s a finite amount of existing demand. Once you’ve captured your share of the people already looking for products like yours, more bottom-funnel spend just bids up the cost of the same limited pool. Your ROAS looks great right up until you hit the ceiling.
To keep growing, you have to feed the top of the funnel — creating new awareness and demand that eventually flows down to conversion. Here’s the full-funnel structure we build for clients.
The budget split between these tiers depends on your stage and goals, but a rough starting heuristic for a growth-focused brand is something like 30% top, 30% mid, 40% bottom — then adjust based on where your funnel is actually leaking. If your bottom-funnel ROAS is strong but volume is flat, you’re starved at the top. If your top-funnel reach is huge but conversions are weak, the leak is mid-funnel or in your listings.
Frameworks are useful, but tactics win campaigns. Here are specific performance marketing plays that have driven real results for our clients — the kind of operational detail that separates a campaign that works from one that quietly burns budget.
Not every region converts equally. For a physical-product brand — especially one with logistics constraints — a huge amount of ad spend is wasted showing ads to people in areas that rarely convert or are expensive to serve.
One of our long-term clients, a Malaysian frozen food brand, used CRM and order data to identify their highest-converting cities — Johor Bahru, Penang, Klang Valley, Ipoh — and ran geo-targeted Facebook CPAS campaigns focused only on those high-conversion areas. By cutting out the geographies that drained budget without returning sales, they dramatically reduced ad waste and lifted overall ROAS. Same product, same creative, same budget — just pointed at the right map.
Acquisition and retention need different ad strategies, but most brands blur them together — wasting acquisition budget re-targeting people who already bought last week, and treating loyal customers like cold prospects.
The same client built a repeatable acquisition system by excluding anyone who'd purchased in the past 180 days from their prospecting campaigns. This forced the acquisition budget to do its actual job — bringing genuinely new buyers into the funnel — rather than claiming credit for repeat purchases that would have happened anyway. They fed this machine with content showcasing the product story: grocery delivery convenience, how the chicken essence is produced, real buyer reviews, and KOL cooking collaborations.
The result over a year: more than 22,000 new buyers acquired across Shopee and Lazada, while the repeat-buyer base grew in parallel — because acquisition and retention were finally being measured and optimized separately.
THE PRINCIPAL UNDERNEATH BOTH TACTICS
Precision beats volume. The instinct when growth slows is to spend more, broaden targeting, reach more people. The better move is almost always the opposite — get more precise about who you’re targeting, where, and at what stage of their relationship with you. Cutting wasted spend often grows profit faster than adding new spend.
Ad costs and conversion rates swing dramatically across the SEA campaign calendar. During mega campaigns (9.9, 11.11, 12.12), platforms inject traffic and vouchers, conversion rates spike, and your acquisition cost drops — but competition for ad placement also intensifies. In quiet months (Q2, July), traffic is lower but ad costs are cheaper.
Smart budget pacing means front-loading acquisition spend into the windows where platform subsidies make new buyers cheapest, and pulling back when there's no tailwind. This connects directly to the three-calendar planning approach we'll cover in Chapter 8 — your ad budget should follow the calendar, not fight it.
This is where Chapter 4 and Chapter 5 connect directly. Your organic social commerce content is a testing ground — the videos that perform organically are your proven ad creative. Don't guess what creative will work in paid; let the organic algorithm tell you, then put spend behind the winners (Spark Ads on TikTok, boosting top organic posts on Meta). The best-performing ad accounts we run are fed by a constant stream of organic content winners, not creative dreamed up in isolation.
For the frozen food brand referenced throughout this guide, here's what a year of disciplined, full-funnel performance marketing looked like across channels:
Shopee Ads: a 168% increase in ads-driven GMV year-on-year, with prospecting expanded across multiple product categories. Lazada CPAS (Facebook): roughly RM35K in spend producing RM174K in ads-driven GMV — a 4.92x return, with individual months hitting 8-10x. Shopee Live Ads: the standout — RM2K in spend producing RM73K in GMV at a 36x blended return, including one campaign month where a tiny spend behind a strong live session returned several hundred times over.
None of these numbers came from a clever bidding trick. They came from the system: optimized listings (Ch 3) that converted the traffic, social content (Ch 4) that fed the creative, geo and audience precision that cut waste, and budget pacing aligned to the campaign calendar.
This is the strategic question every SEA operator now faces. In response to TikTok Shop’s rise, all three marketplaces have rolled out AI-powered ad tools — Shopee, Lazada, and TikTok Shop all now offer “smart” campaign products that promise to handle targeting, bidding, and optimization for you. TikTok’s GMV Max is the most prominent, but every platform has its version.
The pitch is seductive: just set a goal, hand over the controls, and let the algorithm do the work. And for some brands, in some situations, it works well — particularly when you have strong creative, clean conversion data, and enough volume for the algorithm to learn from.
But there’s a trade-off the platforms don’t advertise.
Our view, which has held up across many client accounts: AI ad tools are a powerful accelerant, not an autopilot. They work best when you already understand your funnel, your creative is strong, and you’re using automation to scale something that’s already working — not to paper over something that isn’t. Handing full control to the algorithm before you understand your own economics is how brands end up with great-looking dashboards and shrinking margins.
The platforms benefit when you spend more. Their AI is optimized for their definition of success (GMV, spend), which overlaps with yours but isn’t identical to it (profit). Keep enough manual oversight to make sure the algorithm is serving your goals, not just the platform’s. Trade control for convenience deliberately — knowing exactly what you’re trading.
Performance marketing generates an overwhelming amount of data. Here’s the small set that actually drives decisions:
THE ROAS TRAP
A 5x ROAS sounds great until you realize your contribution margin after platform fees, vouchers, and COGS is only 18%. A high ROAS on a thin-margin product can still lose money once every cost is counted. This is why performance marketing can’t be separated from the profitability math in the next chapter. ROAS without margin context is a vanity metric.
Everything in this chapter assumes you know your real numbers — your true cost to acquire, your actual contribution margin, your genuine take rate. But most brands don’t. They know their GMV and their ROAS, and they assume the profit is in there somewhere.
It often isn’t. The next chapter is about the costs that quietly eat your margin — and how to manage them before they manage you.
