Three Case Studies: Their Playbook for Success in the Southeast Asian Market

A movie streaming site in Vietnam. A novel platform in Indonesia. A gaming content site in the Philippines. These 3 sites share no content, but all three make good, steady money as Southeast Asian publishers. They all use similar ad formats that perform really well in a region that shops online more than almost anywhere else. Let’s look at what each one is doing right, and what any SEA publisher can copy, no matter their niche.

Football? What Football?

Every big sports tournament brings a similarly sized wave of traffic to online publishers. This traffic is massive and worth celebrating while it lasts. But it disappears as soon as the tournament ends, and a publisher relying on it has to wait for the next big event.

The three publishers below never had that problem, because none of them depend on a busy season. Their traffic comes from people who want to watch a specific film, finish a specific chapter, or download a specific file. This kind of demand never stops or slows down.

Case Study #1. Vertical: VOD. GEO: Vietnam

Vietnam earnings on this site went up almost five times over four weeks in mid-2026, from $256.64 to $1,045.67. That kind of jump in one market points to a site that has earned real trust with a specific audience.

Nearly all of this site’s money comes from Vietnam. The language, the branding, and the release schedule are all built specifically for Vietnamese viewers, and that focus is what makes the numbers work.

The Explanation

▪️High-intent keywords. The site targets specific movie and show titles that Vietnamese users are already searching for by name, so visitors arrive already knowing what they want to watch.

▪️A release schedule that brings people back. New titles go up on a regular schedule. This brings the same visitors back, and it also helps the site rank higher in search results than newer competitors.

▪️A site built to look local, not translated. The name and design look like they were made by a Vietnamese team for Vietnamese users. It doesn’t look like an international site that just added a Vietnamese language option.

Case Study #2. Vertical: Manga. GEO: Indonesia

Indonesia earned $1,887.10 from 11 million impressions in a single month. Numbers like that come from serving one audience closely, chapter after chapter. This is a site that built one specific readership, and built it well.

The Explanation

▪️A format that turns reading into a habit. New chapters come out on a schedule, so readers come back for the next one instead of visiting just once.

▪️A site that keeps growing in search results on its own. Every chapter is its own page that search engines can find, and each page targets Indonesian search terms. This means the site’s search visibility keeps growing without any extra SEO work.

▪️Long reading sessions with no annoying ads. Readers stay on the site much longer than average, and the site uses display ads instead of more disruptive formats, so the extra time doesn’t push visitors away.

Case Study #3. Vertical: Gaming, GEO: Philippines

This publisher is based in the Philippines, but the Philippines isn’t even the top-earning market. The United States earns the most, at $1,190.90 from 25,149 impressions, with an RPM of $47.35. The Philippines is second, at $264.40. Many other countries earn well on this site too, including Indonesia, Brazil, the UK, Mexico, Germany, Vietnam, and France.

The Explanation

▪️Visitors arrive already looking for something specific. A gamer comes for a particular mod, item, or piece of content, not to browse randomly. That kind of focused visit holds attention longer than a random one, giving an ad more time to actually get seen.

▪️Years of trust, not months. This site has been running for a long time, and that history helps it rank above newer sites chasing the same searches.

▪️Content that doesn’t need one language. Games and content around them aren’t tied to any single language, so a site based in the Philippines still gets serious traffic from outside South-East Asia.

What Do The Case Studies Have In Common?

Three niches, three countries, and no shared content. What connects them is the ads running on each site.

All three sites use display and in-page push ads for eCommerce advertisers, and this works because people in SEA shop online more than almost anywhere else. The eComm giants all now have their own double-digit sale days, like 9.9, 10.10, 11.11, and 12.12. Earnings go up a lot across the region on those dates.

The numbers in this case study were recorded before any of the double-date sales, which shows this already works well on a normal week. An eCommerce ad running through display or in-page push just needs a visitor who’s already ready to shop, and that describes most of the region every single week.

The novel site’s long reading sessions and the VOD site’s repeat visits both mean more ad views per visitor, without adding a single extra ad. That’s what connects all three case studies: more attention from each visitor, which earns more money.

The Playbook

You may not be able to copy the exact niche. But you don’t need to. What’s worth copying is the habits and lessons behind it.

▪️Match the ad format to how long people stay. A novel or comic reader stays for hours, so anything that interrupts their reading will make them leave. A gamer is often there for one specific action, so they can handle a stronger ad format that would push a reader away. Know how long your visitor stays before you choose a format.

▪️Build content that brings people back on its own. A new movie, a new chapter, or a new file all give the same visitor a reason to return, without paying for ads to bring them back. All three publishers in this piece grew this way instead of spending on marketing. It also helps twice over: every new chapter or file is also a new page that search engines can find, which brings in new visitors too.

▪️Use display and in-page push ads for eCommerce demand. These two formats already work well across three very different niches in this region. Pop-under can also have very strong RPM. It’s worth testing pop-under for eCommerce ads too, instead of avoiding it just because of its reputation.

▪️Build trust before anyone sees an ad. For a local audience, that means a site that looks and feels like it was made for them. For a global niche, it means staying online for years and slowly outranking newer sites that target the same keywords.

Conclusion

Look past the content, and the same pattern shows up time and time again, even beyond these case studies. Pick one thing, get a great site together, and let the ad formats that fit your audience do the earning.

None of them needed a single big event to hit single, big numbers. They earn the same way in a quiet month as they do in a busy one, because their traffic was never tied to a calendar in the first place.
