Ad Network Guide
Playable Ads for InMobi
InMobi is a global independent mobile advertising platform founded in India in 2007, now operating one of the largest independent mobile ad networks in the world. Unlike most platforms covered in this guide, InMobi is not primarily a gaming network. It serves a broad range of app categories including e-commerce, fintech, travel, entertainment, and lifestyle apps alongside gaming advertisers. This diversity of publisher and advertiser clients means InMobi's audience targeting capabilities span demographics and interest categories that purely gaming-focused DSPs cannot match. That range of publishers matters most for apps that appeal to people beyond gamers.
InMobi operates with particularly strong publisher relationships in South Asia, Southeast Asia, and the Middle East & Africa: markets where Western-focused gaming DSPs have thinner coverage and consequently higher CPIs for advertisers willing to invest. For gaming advertisers targeting India, Indonesia, the Philippines, Nigeria, or similar high-growth markets, InMobi often delivers significantly more efficient installs than Western-centric networks. InMobi's specification calls for MRAID 3.0, with mraid.js in the head and the ad waiting until it is on screen before it starts; playables follow the same rules as InMobi's Interactive End Cards, so one export serves as either.
The upload process runs through InMobi's DSP dashboard, where you create a campaign, add a creative unit, and upload your HTML file under the Rich Media or Playable format. InMobi's creative team reviews playables for content policy compliance and technical correctness before approval. The platform supports both programmatic and managed-service campaign models depending on your spend level and relationship with InMobi's team. For self-serve advertisers, the InMobi DSP dashboard provides direct creative upload, audience targeting configuration, and campaign performance reporting.

If you already have a build, drop the HTML file into the free Playable Ad Spec Checker and it will grade it against these InMobi requirements (size, packaging, MRAID and the store-exit call) in your browser, with nothing uploaded.

- Build your playable in the Playable Ads Maker. If targeting non-gaming audiences on InMobi's diverse publisher base, ensure the interaction is broadly intuitive. Avoid gaming-specific conventions like health bars or score counters that non-gamers may not immediately understand.
- Select the InMobi preset in the Export modal and download the HTML file with MRAID wired to your CTA.
- Check the file makes no network requests: InMobi's specification rules out XHR and dynamic asset loading, and any redirect without a user action. InMobi publishes 5 MB; Playable Ads Maker builds InMobi exports to 5 MB.
- Log in to the InMobi DSP dashboard with your advertiser credentials. If you are on a managed-service plan, coordinate the creative upload with your InMobi account manager.
- Navigate to Creatives > Rich Media / Playable and click Upload Creative. Select your HTML file.
- Fill in the required creative metadata: app name, bundle ID, iOS store URL, and Google Play URL. InMobi uses these to route the CTA redirect correctly by platform.
- Once the creative is approved, set up your campaign with geo targeting (select specific countries or regions), audience segments, and your CPA/ROAS goal, then activate the campaign.
File size tip
InMobi publishes a limit of 5 MB; Playable Ads Maker builds InMobi exports to 5 MB. If your export is too large, reduce image resolution, switch to WebP at 75–80% quality, or trim animation frame counts in the Playable Ads Maker Export modal. The live size estimate updates as you adjust each setting.
Tips for InMobi playable ads
InMobi's non-gaming inventory suits lifestyle and utility apps
Most playable ad guides focus on gaming UA, but InMobi's publisher base includes significant inventory in news apps, content aggregators, utility tools, and social apps. For advertisers with apps in productivity, fitness, finance, or education categories, running a playable on InMobi's non-gaming inventory can introduce the interactive format to audiences who have never seen it before: novelty alone drives higher engagement. Design your interaction around your app's actual utility (a budget-tracker demo, a language-learning quiz mechanic) rather than an artificial game layer.
Target South and Southeast Asia with InMobi for lower-CPM reach at scale
InMobi's deepest publisher penetration is in India, Indonesia, Vietnam, the Philippines, and Thailand: markets where app install rates are high, competition from other programmatic buyers is lower than in North America and Western Europe, and InMobi's direct publisher relationships provide inventory that other DSPs cannot access. Advertisers running global UA campaigns who add InMobi as an incremental partner for South and Southeast Asian geos routinely see blended CPIs 20–40% below what they pay on primary Western-focused networks.
InMobi's audience targeting supports interest and demographic segments beyond gaming
Unlike gaming DSPs that primarily target by publisher genre, InMobi provides interest-based and demographic audience segments built from its SDK's first-party data across millions of apps. For gaming advertisers, this means you can target users who have demonstrated interest in specific genres even when they are not currently playing a game, for example, reaching puzzle game fans while they are using a news reading app. This adds reach outside the gaming session.
Playable Ads Maker does the InMobi packaging (Single HTML file), wires the mraid.open() store exit and inlines every asset when you export.
