InMobi vs. AdMob: Which Earns More in 2026?
Last Updated July 2026
InMobi vs AdMob comes down to geography: AdMob leads in the US, UK, and Europe, while InMobi wins across India and Southeast Asia via its independent RTB exchange. AdMob vs InMobi eCPM: InMobi holds $1.20–2.50 in India vs AdMob’s $0.80–1.50. Match InMobi vs AdMob, or AdMob vs InMobi, to your audience mix.
AdMob vs. InMobi: Two Networks, Different Strengths
Both networks work, yet they serve different kinds of traffic. Your choice comes down to where your users are and how you plan to make money. AdMob rules in the US, Europe, and Australia, thanks to Google Ads demand and steady high eCPMs. InMobi is independent and shines in India and Southeast Asia, often beating AdMob for each impression in those places.
If most of your daily users are in Asia-Pacific, the story changes. InMobi is not tied to Google, so it taps into demand that AdMob cannot reach. That is a big deal if you want to branch out or if your users are mostly in South and Southeast Asia.
Here, I break down both networks by how they run auctions, which formats they do best, what InMobi pays in different regions, fees, and how tricky setup can get. At the end, you will get a clear answer for each situation.

One-on-One Comparison
Explore each matchup in detail. Each page includes a complete data table, clear pros and cons, and a verdict for each use case.
AdMob
AdMob is a Google-owned ad network and one of the largest demand sources in mobile advertising. It operates within the Google Ads ecosystem, providing extensive reach in Tier-1 markets and simple integration with Firebase Analytics.
InMobi
InMobi is based in Bangalore and stands on its own. It is strongest in India and Southeast Asia. With connections to more than 150 DSPs and its own RTB exchange, InMobi is a solid pick if your app is big in APAC.
How to Choose a Mobile Ad Network
No one network is perfect for every app. Before you begin, keep these four things in mind.
App type and dominant format
If you have a gaming app in the US or Europe, AdMob’s rewarded video and interstitials usually pay the most. But if you rely on native ads, or your app is a utility or content app, InMobi’s native ads are worth a try. Matching your format to the right network matters more than picking the biggest name.
Audience geography
Check where your daily users come from before you decide. If more than 40 percent are in India, Southeast Asia, or Japan, InMobi can match or even beat AdMob’s eCPMs overall, even if the top market rates are lower. The quickest way to know for sure is to run a geo-split in your mediation stack and see what happens with your own traffic.
Mediation or single network
Using either network as your only demand source limits revenue potential. A mediation layer that auctions impressions across both AdMob and InMobi typically delivers higher ARPU than relying on a single network. If you are comparing AdMob and InMobi, consider running both through independent mediation on a net-21 schedule, while InMobi pays on a net-30 to net-60 basis depending on account tier. If cash flow timing is important for your team, consider this alongside eCPM estimates. A 10% higher eCPM with a six-week payout delay may not be the better option.
Where CAS.AI Fits
CAS.AI is not an ad network. It is a growth operator, sitting between your app and all the networks above. With one SDK, you plug into more than 20 ad networks, including AdMob and InMobi, and over 150 DSPs. CAS.AI does not own any ad space and does not care who wins the impression. Every auction goes to whoever bids the most, whether that is AdMob, InMobi, AppLovin, or some DSP you have never heard of.
When apps switch to CAS.AI from a single network or a biased mediation setup, they usually see ARPU jump by 1.5 to 2 times in the first month. That is because every impression gets auctioned in real time to all the demand sources, not just handed down a fixed waterfall.
During the test, you get a no-loss guarantee. If your revenue drops while you are trying CAS.AI, they pay you the difference. You are not guessing or hoping for the best. You measure against your real numbers.
Key Takeaways
- Where your users live makes all the difference here. AdMob is the clear winner in the US, UK, and Western Europe. InMobi, which is not tied to Google, comes out ahead in India, Indonesia, Vietnam, and some parts of Japan.
- If you are looking at top markets, AdMob pays more for rewarded video ads, sometimes double what InMobi offers. But in India, InMobi actually pulls ahead, paying more than AdMob for the same format.
- Because InMobi is independent, it can tap into advertisers that AdMob simply cannot reach. That is a big plus if you want to move away from relying only on Google.
- AdMob pays out faster, usually in three weeks, while InMobi can take anywhere from a month to two months, depending on your account status.
- If your users are spread across these regions, do not just rely on published benchmarks. Run both AdMob and InMobi side by side through a growth operator, like CAS.AI, which can handle the auction for you and even offers a no-loss guarantee while you test.
Ad Network Comparison FAQ
It depends on your audience’s geography. AdMob earns more in the US, UK, and most of Western Europe. InMobi outperforms in India, Indonesia, Vietnam, and parts of Japan. If your DAU splits across both, running both networks in a real-money auction via mediation will tell you more than any benchmark.
In Tier-1 markets, AdMob typically commands $8-15 eCPM for rewarded video vs. InMobi’s $3–6. In India, InMobi reverses that gap: $1.20-2.50 vs. AdMob’s $0.80–1.50. Southeast Asia follows a similar pattern. See the regional table above for format-level estimates.
Yes, and you should. Running them head-to-head through an independent mediation layer lets each impression go to the highest bidder. Apps running on both networks via CAS.AI typically see higher blended eCPMs than either network alone.
Yes. InMobi is not part of Google, Meta, or any major ad holding group. It operates its own RTB exchange and connects to 150+ third-party DSPs. That independence matters if you’re trying to lessen reliance on Google’s ecosystem.
AdMob does not publicly disclose its revenue share terms. Third-party estimates (Metacto, Teqblaze) suggest a 30-40% platform take. InMobi operates similarly. Whichever network you use, the net eCPM after fees is the number that matters, and that’s what your mediation dashboard should report.
AdMob pays monthly on a net-21 cycle. InMobi’s payout window ranges from net-30 to net-60 depending on account tier and region. If cash flow timing is a factor for your team, include it in your comparison alongside eCPM figures.
