Adding up the world :
Global App Promotion Trends
Over 50 Million app installs were delivered on the
InMobi network in 2013 YTD.
InMobi continues to power millions of app installs for top developer studios and
independent developers across the world. In Q2 2013, US continued to be the
most favorite battleground for developers looking to drive downloads on our
global ad network, with several of them also vying to tap into the high smartphone
penetration and expansive mobile subscriber base that markets such as India, China
and Japan represent. As more users get access to mobile media, large markets
such as Indonesia are also becoming increasingly valuable for app developers, with
the country holding the fifth spot on our top list of countries for app promotions.

According to Juniper Research’s report, “Future App Store: Discovery, Monetization&
Ecosystem Analysis 2013-2018,” gaming will fuel a sharp hike in app downloads with
experts predicting that, in 2017, over 160 billion apps will be downloaded globally
onto consumer handsets and tablets. The trends observed on the InMobi network
are in tandem with this prediction, with games as a category representing 64% of
the total apps downloaded through our network.

Creative Matters: Ad formats that work
best for your app
As a developer, you know that designing the right ad experience is crucial to
grabbing the user’s attention and coaxing them to download your app. While simple
banners continue to do this job quite well, mobile advertising today offers far more
interesting options, ranging from rich media and interstitials to expandable ads and
other unique ad formats. So which one do you pick for your app?
07

10. APP INSIGHT REPORT
1a. Interstitials rule the roost
Upto 25% Click through and 10% Conversions seen on interstitial
ads on the InMobi network
When it comes to promoting your app, we notice that there’s something almost
magical about interstitial ads. Maybe it’s the way they expand to overtake your
whole screen with a rich HTML5 image. Maybe it’s the way they demand attention
in an era of quick glances and endless scrolling.
While top game developers on the inmobi network have seen upto 25% click
through and 10% conversion, this ad format is also seen to work very well for a
wide range of content. On our network, we noticed average conversions as high as
8% for comics and 5.6% for health & fitness apps.

Quick Tip: For apps with short app sessions, static
interstitials get the point across immediately
and are found to be the most effective in
driving engagement. On the other hand, for
more engaging apps with longer app sessions,
video interstitials deliver higher eCPMs. Static
interstitials typically are observed to provide
CTRs as high as 20% while video-interstitials are
found to deliver superior ad engagement.

1b. Don’t do away with banners, just yet!
Well, interstitials are the in thing - no denying that. But does that warrant doing
away with good old banner ads?
On InMobi’s network, we notice banners continue to work well for a wide range of
non-gaming content on both iOS and Android.

Quick Tip: For any app promotion campaign, we recommend using a good mix of HD banners
and interstitials to ensure you reach audiences on a wide variety of handsets. Also, rotating ad
formats can reduce ad fatigue and help drive higher ad engagement.

Bang on Target: Sites you should
target for maximum conversions
The mobile consumer today shunts his presence on different mobile sites. So where
do you find the right users for your app?
In this report, we specifically analysed conversions for games, social and
entertainment apps on iOS to understand which sites you should target to drive
maximum installs while promoting your app.
InMobi Insight: Almost all kinds of sites delivered good downloads on games suggesting that the audience for this category is diverse and widespread. Sports
and health & fitness sites delivered maximum downloads for social apps. On the
other hand, communication sites delivered the most downloads for entertainment
apps.

Ads that work well on tablets
Consumers are increasingly utilizing tablets for shopping, game play and
communication. The same optimized banner ad on a tablet app may perform
completely different from an ad on a smartphone app. Knowing your target
demographic on tablets or smartphones and what type of ads they engage with
the most is crucial to designing an effective app promotion strategy on tablets.
A quick comparison between tablet CTRs and average ad network CTRs reveal
that text ads don’t work well on tablets. However, interstitial ads deliver solid
results with almost 46% higher CTR for tablet campaigns.

Top 3 tips to make your tablet
campaigns work:
01
02
03
Leverage the real estate: Take the effort to optimize your ad size for
tablets. Tablet optimized ads tend to deliver 3x higher conversions and
ROI .InMobi recommends using the 728×90, 300×250 , and 468×60 slot
sizes for best results on your tablet campaign.
Bid at the right price: Tablet users tend to have higher LTV, and are
on average, better spenders as well. This increases demand for tablet
advertising and most advertisers are already bidding more. InMobi
recommends that you bid about 1.5 – 2x more on tablets to hit the scale
that you want.
Mix and match: High definition ad formats match perfectly with the highresolution display of tablets, creating a deeply engaging experience for
users. InMobi recommends rotating between HD banners, Interstitials
and video ads to reach your users in the most optimal way.

Cut costs without cutting corners
Agreed it’s a competitive marketplace out there. You don’t know your user’s Lifetime
Value (LTV) and can’t decide how much to spend on acquiring users. But not all apps
are created equal. Depending on what kind of app you have built and the country
you target, the cost to drive a download ( CPD) could vary significantly.
20

23. APP INSIGHT REPORT
Indexed against the costs in the US, our research indicates that driving a download
in most markets, especially in China, Japan and Korea is relatively cheaper in comparison to
the US market , with the UK representing the most expensive markets and India the least
Expensive.

Chart 11: CPD Index By Country, Q2 2013
Note: Index calculated using USA as base
21

24. APP INSIGHT REPORT
CPDs also vary drastically by the type of content you promote and depend
on the average lifetime value (LTV) of the app’s user. Higher the LTV, higher
the CPD tends to be. For example, a travel app developer is usually willing
to pay much more to acquire a user, compared to the average game
developer, since the expected revenues from a loyal user can be much
higher, at times upwards of $100 USD. This reflects in the average CPDs we
notice on our network, with travel and financial service apps topping the
charts on CPDs bid on the network.

Market Spotlight: Taming
the Chinese Dragon
“Let China sleep, for when she awakes, she will shake
the world.” Napoleon
And indeed, she did just that! According to IDC, in February 2013, China overtook
the US to become the world’s largest smart device market, with 246 million devices
(against the US 230 million) and accounted for 26.5% of all smartphone shipments
last year.Concurrent with the growth in smart devices, mobile applications are also
growing at an astronomical rate. In addition, the falling price of the iPhone and the
increasingly capable low to mid-range Android handsets now available have further
propelled this growth. As attractive as the market may be, China is no easy beast to
tame!
Cultural barriers, piracy concerns, fragmented app distribution ecosystems and
the need for localization have prevented most app developers from entering this
market. The common perception that Chinese app users were not willing to pay for
content and that app usage levels were not high enough to warrant investments in
heavy marketing, have kept most developers away from China.

Top 3 Tips to Win in the Chinese
App Market
01

03
Localize your app: While translating apps into simplified Chinese
is essential, localization should go beyond simple translation – it is
important to connect with users’ emotions and culture. Customizing
with Chinese avatars and timing app launches with Chinese festivals is
a good strategy.
Go freemium to beat piracy: Paid apps are quickly pirated in China
with up to 42% of Chinese iOS devices being jail broken and 17% of apps
copied or pirated. Overcome piracy by using a freemium monetization
model and by making frequent updates to your app.
List your app on the right stores: With over 500 stores, China has
one of the most complex and fragmented Android app store ecosystems
in the world. Carefully select the right app stores to reach the right
audience.
The largest App Stores include Anzhi, AppChina, Gfan, Hiapk, Mobile
Market, Nduoa, Snappee, Tencent, Wandoujia, Baidu App Store, Opera
Mobile App Store, and Pandaapp.
