Performance Marketing in Southeast Asia

Southeast Asia (Indonesia, Vietnam, the Philippines, Thailand, and neighboring markets) has one of the most mobile-first audiences in the world — a large share of users go online exclusively through a phone, skipping desktop entirely.

Why SEA is mobile-first in the truest sense

Unlike markets with an established desktop culture, a smartphone is the primary — often the only — way most of the region's population goes online. That makes mobile optimization non-negotiable rather than optional: desktop traffic here is a minimal share of overall audience.

Top verticals by demand

• Nutra — especially subscription-model mobile apps
• Sweepstakes — high volume of cheap traffic for giveaways and quizzes
• E-commerce — a fast-growing segment, particularly mobile commerce
• iGaming — growing demand with uneven regulation across the region

MediaGo and local native networks

Unlike Latin America, where Facebook and TikTok dominate, Southeast Asia gets a meaningful share of reach from local native networks and MediaGo, which has historically had a strong presence in this specific region through direct local publisher partnerships.

Moloco for mobile apps

For subscription or in-app-purchase mobile offers, Moloco is especially effective on Asian geos — the platform has more accumulated data on these markets specifically, which sharpens ML bidding on post-install events from the start.

Language and cultural diversity across the region

Southeast Asia isn't one market — it's a set of countries with different languages (Indonesian, Vietnamese, Thai, Tagalog) and different levels of digital maturity. A funnel that works in Vietnam rarely ports directly to Indonesia or the Philippines without adaptation.

Payment specifics

E-wallets (GoPay, OVO, GrabPay, and local equivalents) are often more popular than bank cards for online payment in the region — supporting these on your landing page has a direct effect on final conversion, especially for e-commerce and subscription offers.

Test funnels one country at a time rather than launching a broad "Southeast Asia" geo target — the markets inside the region differ enough that sequential country-by-country scaling outperforms a single broad launch.

The takeaway

Southeast Asia is a mobile-first region with strong potential in nutra, sweepstakes, and mobile apps, where local native networks like MediaGo and platforms like Moloco unlock audience that Western traffic sources simply can't reach.
