popIn is a content recommendation and native advertising platform operating across Japan and Southeast Asia. It runs the largest native ad network with more than 400 traffic sources in Japan, and holds a strong position in Thailand, Malaysia, Singapore, Indonesia, South Korea, and Greater China. The platform specializes in AI-powered native ad solutions that blend seamlessly into editorial content, and delivers over 10 billion monthly page views across its publisher network.
Publisher network
popIn Discovery connects advertisers to 10,000+ premium publisher sites across APAC. Partners include top-tier news platforms and editorial media in each market. Publishers integrate locally in each country, giving advertisers access to placements that match the cultural context of each audience. Brand safety comes from the quality of these direct publisher relationships.
Ad formats
The platform’s core format is native recommended content, ads that appear as article recommendations within and below editorial content. This places branded content in the same format readers use to discover organic articles. The format works across desktop, mobile web, and in-app environments.
READ algorithm
popIn’s proprietary READ algorithm measures actual reading behaviour rather than simple viewability. It tracks elapsed reading time and the volume of content consumed. This determines whether a user genuinely read an article or scrolled past it. Advertisers get a clearer picture of real content engagement, not just impressions.
AI targeting
An AI-powered recommendation engine personalises ad placements based on each user’s browsing behaviour. The system matches content ads to users most likely to engage. It bases this on reading patterns and interest signals. Targeting options cover region, interest category, and device type.
Why use it
For advertisers targeting Japanese or Southeast Asian audiences, popIn Discovery provides reach that most Western platforms don’t cover. Local publisher integrations in each market give ads cultural context alongside scale. The platform suits brands entering Japan, Thailand, Indonesia, or other APAC markets. It gives access to premium editorial inventory from one place.
