How to Grow Your eCommerce
Brand on Shopee, Lazada
and Beyond in 2026

Back to blog

I helped launch Amazon Spain. I've spent years studying how the world's best commerce platforms work from the inside. And when I look at Southeast Asia today, I see the same pattern I saw in European ecommerce five or six years ago: brands that understand marketplace mechanics early are building enormous advantages that latecomers struggle to close.

Shopee and Lazada combined reach hundreds of millions of active buyers across Southeast Asia. For any ecommerce brand — whether you're selling on Shopify, running a D2C store, or both — these platforms represent one of the most significant untapped growth opportunities available right now. And most brands are only scratching the surface of what's possible.

Why Most eCommerce Brands Underperform on Marketplaces

The most common mistake I see is treating Shopee and Lazada like a passive listing directory. Brands upload their products, set a price, maybe run a flash sale once a month, and wonder why growth has plateaued.

The reality is that these platforms are sophisticated search and discovery engines with their own algorithms, advertising systems and content requirements. Winning on them requires the same level of strategic thinking you'd bring to your Shopify store — arguably more.

Here's what separates the brands that grow from the ones that plateau:

1. Listing Optimisation Is Your Organic Growth Engine

Shopee and Lazada both run search algorithms that determine which products appear when buyers search for "vitamin C supplement" or "collagen drink" or "natural moisturiser." Most brands don't optimise for these algorithms at all — and then wonder why their products don't appear.

Effective marketplace SEO involves:

• Keyword research specific to how SEA consumers search in your category — often very different from Western search behaviour
• Titles structured to lead with the most searched terms, not your brand name
• A+ content (enhanced product descriptions) that addresses trust barriers specific to health purchases
• Review velocity strategy — the platforms heavily weight recent reviews in ranking
• Image sets that follow platform best practices and convert mobile browsers into buyers

Get this right, and your organic traffic compounds over time without ongoing ad spend. It's one of the highest-ROI investments any ecommerce brand can make on these platforms.

2. Flash Sales Are a Growth Strategy, Not Just a Promotional Tactic

The biggest commercial events on Shopee and Lazada — 9.9, 10.10, 11.11, 12.12 — generate enormous volumes of traffic and conversions. But treating them as one-off promotions misses their strategic value.

"The brands that win flash sales aren't the ones that discount the deepest. They're the ones that have built the organic ranking, the review count and the campaign mechanics to capitalise on the traffic surge."

A well-planned flash sale strategy involves preparing months in advance: building your review base, optimising your listings, structuring your bundles for the event, and using the platform's in-built advertising tools to amplify your organic position during peak traffic windows.

Flash sales are also one of the most powerful customer acquisition tools on these platforms. Someone who discovers your brand during a promotional event — and has a great experience — can become a loyal repeat buyer at full price. That's where the LTV calculation gets very interesting for any ecommerce brand.

3. Marketplace Ads Work Differently Than Meta or Google

Sponsored Products on Shopee and Lazada operate on a different logic than social or search ads. You're not interrupting someone's feed — you're appearing alongside organic results for people who are already in buying mode.

This means the conversion intent is higher, but the competition is also more direct. You're bidding against other brands in your exact category for the same high-intent keywords.

The brands that get this right structure their marketplace ad spend to:

• Target keywords where they already have organic ranking — amplifying existing momentum rather than buying traffic from scratch
• Use defensive bidding on their own brand terms to prevent competitors stealing their traffic
• Concentrate spend around flash sale windows when platform traffic is highest and conversion rates peak
• Feed performance data back into listing optimisation — the ads tell you exactly which keywords convert

4. The D2C and Marketplace Connection Most Brands Miss

Here's something I see constantly: brands treating their Shopify store and their marketplace presence as completely separate businesses. Different teams, different strategies, different creative, different pricing.

The brands growing fastest treat them as one connected system. Your marketplace presence drives brand discovery. Your Shopify store captures buyers who want to go direct. Your email marketing — built from both channels — drives the repeat revenue that makes the unit economics work.

When you connect these dots properly, the whole system compounds. Marketplace review volume builds brand credibility that improves Shopify conversion rates. Email subscribers from your D2C store can be nudged toward marketplace purchases during flash sale windows. The creative that works on TikTok gives you the raw material for marketplace image sets.

The AI Layer That Changes Everything

In 2026, the brands moving fastest on Shopee and Lazada are using AI to do things that simply weren't possible two or three years ago: automated listing optimisation across hundreds of SKUs, AI-generated product image variations tested at scale, predictive inventory positioning ahead of flash sale events, and AI-driven review analysis to identify and fix conversion blockers before they compound.

This is something we build into every Growth Partnership at Altiora — AI-powered marketplace management that gives our clients an unfair advantage over brands still doing this manually.

Marketplace growth in SEA is one of the most exciting opportunities in ecommerce right now. The brands that invest in getting this right — the listing optimisation, the flash sale strategy, the Shopify-to-marketplace connection — are building moats that are genuinely hard to compete against.

If you're an ecommerce brand looking to take your marketplace presence seriously — whether you're just starting on Shopee and Lazada or want to scale what you've already built — I'd love to talk.
