In-app advertising is an effective monetization strategy for mobile publishers, in which app developers get paid to serve advertisements within their mobile app. Not only do apps drive mobile usage — they also drive global media consumption. This makes in-app advertising a vital marketing channel for brands and agencies. With sophisticated data tracking and user targeting, the in-app environment also allows advertisers to reach consumers with pinpoint accuracy.

Mobile Websites vs. Mobile Apps

Mobile apps offer a much more engaging and dynamic environment than that of the mobile web. Compared to mobile web, this makes the in-app environment an effective medium for advertisers to capture consumers’ attention and encourage them to view and interact with their ads.

Here are some of the key differences between mobile websites and mobile apps:

Mobile Websites Mobile Apps

Device ID
Web activity (e.g. shopping habits, favorite websites, etc.)

Consumers Spend More Time In-App

Apps are capturing an increasing amount of consumers’ attention. Over 25% of total media time and 89% of mobile time is spent in-app according to eMarketer; however, there is still a disparity between the amount of time that people are spending in-app and the number of ad dollars allocated to this medium.

Mobile devices, unlike desktop or laptop computers, are more often only used by one person. This means that the apps on a particular device are closely connected to the personal life and daily habits of its owner. This also makes the in-app environment an ideal place for advertisers to create effective and personal advertising touchpoints.

Accurate In-App Ad Targeting

Since apps are able to collect first-party data on an opt-in basis, they are also able to pass valuable targeting parameters such as gender and age. This makes it easy for advertisers to precisely reach their ideal audience through in-app advertising.

Within the in-app environment, advertisers can also harness geo-location data to ensure that they are reaching users at the right time and in the right place.

In-App Advertising Targeting Data

Tracking Users In-App

Within the in-app environment, active user identification is tied to the device ID of each unique mobile device. This enables in-app advertising to provide true people-centric targeting, given the personal nature of mobile devices. Furthermore, most apps are opt-in, and device IDs last for an average of 21 months — about 630 times longer than the average cookie.

Mobile Web Cookies Mobile Device IDs
  • Tied to browsers
  • Decay within 24 hours
  • Not opt-in
  • Tied to users
  • Last for an average of 21 months
  • Users opt-in to each app’s policies when they download the app

Private Marketplace & Programmatic Deals

Customized programmatic deals are an effective way to ensure that in-app advertising campaigns reach their target audience at the right mobile moment. Not only do they provide more transparency and control, but they are effective tools for optimizing campaigns, inventory, and pricing.

Types of Mobile Programmatic Buying
  • Preferred Deals: Direct pre-auction deal with one buyer at a fixed price.
  • Private Auctions: 2nd price invite-only auction with variable floor prices set per buyer.
  • Open Auction (RTB): 2nd price real-time auction with all buyers.

Programmatic Deals

Buying inventory through programmatic deals creates a direct relationship between advertiser and publisher, allowing advertisers to know exactly who is seeing their ad and in which context. When working directly with supply partners, there are multiple programmatic buying options available. At Smaato, we recommend both Private Marketplace and Open Deals:

Private Marketplace Open Deals
Private Marketplace (PMP) is an exclusive RTB auction where selected buyers are invited to bid on specific ad placements. PMP inventory can be built around numerous variables, including audience data, content type, impression attributes, and more.

Types
  • Preferred Deal: non-guaranteed, first look, fixed price setup using RTB infrastructure
  • Private Exchange: RTB auction only with preselected buyers
With Open Deals, buyers can purchase a package of inventory across different publishers based on their targeting goals or customize their own package with specific apps and ad spaces. These deals will still be executed at the open auction level, but create predetermined parameters around the exact inventory being bid on.

Types
  • “Curated Marketplace” or whitelist of selected publishers/inventory
  • Open market deals
  • Option for no fixed or floor prices
  • Packages based on demand partner needs

Measuring In-App Ad Viewability

In-app advertising, or any advertising for that matter, can only be effective when it is viewed by real people. In the mobile world, an ad can only be considered viewable if the ad content is within the viewable area of the app or mobile website for a minimum period of time.

To provide an industry standard for measuring viewable mobile ad impressions, the Media Rating Council (MRC) published the “Mobile Viewable Ad Impression Measurement Guidelines.” According to the guidelines, a mobile display ad impression can only be considered viewable if it fulfills the following requirements:

  • Pixel requirement: At least 50% of the advertisement’s pixels (density-independent) must be on an in-focus browser or a fully downloaded, opened and initialized application in the viewable space of the device.
  • Time requirement: The duration in which the pixel requirement is met must be at least one continuous second, post ad render. This time requirement applies equally to news feed and non-news feed environments.

There are currently several organizations and industry standards that are working to ensure that objective and fair viewability measurement is available in-app.

In-App Advertising Viewability Verification Providers

The IAB Tech Lab is also leading the development of a new technical tool for in-app mobile viewability measurement, the Open Measurement Software Development Kit (OM SDK), which will be the first industry-approved open source viewability measurement SDK. As a leader in the in-app space since 2005, Smaato is an active participant in the Open Measurement Working Group (OMWG), which is reviewing, testing and maintaining the SDK. This new viewability measurement standard will be the next step in ensuring a high-quality, transparent advertising ecosystem.

Mobile Programmatic Supply Chain

Mobile programmatic advertising is an automated process of buying and selling mobile media at scale, making it an important component of any in-app advertising strategy. The mobile programmatic industry is a complex environment that requires trust and transparency between all supply and demand partners. This is especially important for advertisers to maintain control over their creatives as they move through the programmatic supply chain and are ultimately served on a user’s mobile device.

The diversity of programmatic ad technology services has expanded rapidly over the past several years as the industry responds to evolving marketplace dynamics. These third-party tools provide an unprecedented level of control for both advertisers and publishers; however, the increasing complexity in the programmatic supply chain has made it difficult for advertisers to keep track of which parties are involved in the delivery of their creative and which fees are taken by these parties along the chain.

The first step in improving transparency is to deconstruct the individual components of these ad technology layers and their value propositions. Here are the main players in the mobile programmatic advertising industry:

Mobile Programmatic Advertising Supply Chain

  • Agency: An advertising agency is typically an independent organization that handles the advertising, promotion, and marketing for multiple clients. In order to conduct large-scale mobile programmatic transactions for their clients, agencies can work with a trading desk or directly with demand-side platforms (DSPs).
  • Trading Desk: Many advertising agencies have a dedicated team for executing online media buying, which is referred to as a trading desk. Trading desks can use either proprietary technology or a DSP to buy inventory.
  • Demand-Side Platform (DSP): A DSP allows buyers of digital advertising inventory (whether trading desks, agencies, or advertisers directly) to manage multiple ad exchanges via one interface.
  • Ad Exchange: An ad exchange is a technology platform that facilitates the buying and selling of advertising inventory between DSPs and SSPs.
  • Supply-Side Platform (SSP): SSPs connect directly with publishers, enabling them to make their inventory available to multiple ad exchanges, DSPs, and advertisers in order to maximize revenue.

In-App Ad Formats

Apps offer a dynamic environment that allows for advertisements to be seamlessly integrated within the in-app content. This turns mobile ads from an unwelcome distraction to a relevant suggestion that actually enhances the users’ in-app experience. When choosing the right ad formats for an in-app advertising campaign, advertisers should consider how consumers use their device and will experience the ad.

Video Ad Formats

Mobile video advertising is an integral part of a successful advertising strategy that engages audiences on the small screen. By leveraging the unique qualities of mobile devices, mobile video ad formats can effectively deliver engaging brand messages.

AD FORMAT

Interstitial Video Ads

Interstitial video ads are full-screen videos that appear during a natural break within the app — for example, after completing a level in a mobile game. This engaging ad format is attractive to advertisers because it fills the user’s entire screen, grabbing their attention and allowing the advertisement to tell a rich story.

AD FORMAT

Rewarded Video Ads

Gaming apps can integrate rewarded video ads as an integral part of their product, enabling users to gain virtual goods or currency that advance the game in return for watching a video ad. Rewarded video is an effective method for advertisers to gain informed clicks and high-quality conversions. Since this ad format is opt-in, it also has the highest viewability rates of any mobile ad format.

AD FORMAT

Outstream Video Ads

Outstream videos are placed within the in-app content (i.e. between images or paragraphs of text), and the ad auto-plays when it reaches the viewable area of the app. Since these ads only play when they are visible to the user, they also have high viewability rates.

AD FORMAT

Instream Pre-Roll Video Ads

Instream pre-roll videos play before, during, or after video content within the app’s native video player. This ad format is popular among publishers that offer video content within their app. Since mobile video viewership is growing rapidly, pre-roll video ads are an increasingly popular and effective way to grab the attention of consumers.

Display Ad Formats

In-app display ads provide advertisers with a flexible way to scale their campaign reach within the in-app environment. These formats provide users with a discovery experience that is tailored to the unique context of the app and the behaviors and interests of the user.

AD FORMAT

Native Ads

As the name suggests, Native ads fit the native look and feel of non-advertising content units within an app. This creates a highly-effective and non-disruptive user experience where advertisements feel like native in-app content and are perceived as a welcome suggestion or idea.

AD FORMAT

Interstitial Ads

Interstitial display ads appear full-screen during a content break within the app. Since these ads fill the screen, they are one of the most engaging in-app display ads.

AD FORMAT

Banner Ads

The original mobile ad format is the Banner ad. Although small in size, these ads have a huge reach, which makes them an effective option for creating brand awareness.

AD FORMAT

Medium Rectangle Ads

With a larger visual impact than traditional banners, Medium Rectangle ads offer high viewability at a low cost.

Best Practices for In-App Advertising Success

With ever-increasing usage and superior technical capabilities, it’s clear why advertisers should invest in in-app — now it’s time to look at how to best invest advertising budgets in-app.

Here are some best practices for in-app advertisers, which advertisers can apply to their next in-app advertising campaign to optimize their strategy and maximize campaign performance:

  1. Know Where Your Ads Go

    Familiarize yourself with the mobile programmatic supply chain and understand the role of each participant.

  2. Choose Supply Partners Wisely

    Many premium publishers only work with a small selection of supply-side platforms (SSPs), and working with SSPs that have direct relationships to high-quality inventory is the best way for advertisers to maintain control over their ads and get the best return on investment.

  3. Select Banners for Reach

    For a low-cost, large-scale in-app advertising campaign, no ad format can beat the classic mobile Banner ad. These versatile ad spaces continue to be popular among app publishers due to their ability to easily fit into in-app environment without being intrusive to the user experience.

  4. Make an Impact With Interstitial Ads

    Full-screen ads make the largest visual impact on the user, which means that these formats are effective for engaging consumers during natural content breaks within the in-app environment.

  5. Maximize Engagement With Interactive Video Ads

    Interactive video ads are a great way to encourage users to engage with a creative and complete the desired action. VPAID (Video Player-Ad Interface Definition) is a video ad delivery format that allows advertisers to program interactive features directly into ads, and it also allows an advertiser’s preferred viewability tracking solution to be implemented, regardless of whether the specific measurement provider is integrated into an app’s SDK.

  6. Gain High-Quality Conversions With Rewarded Video Ads

    Another effective method for gaining informed clicks and high-quality conversions is to use rewarded video ads. Since this ad format is opt-in, with users choosing to watch in exchange for a reward, it has the highest viewability rates of any mobile ad format.

  7. Take Advantage of Private Marketplace & Programmatic Deals

    Buying inventory through programmatic deals creates a direct relationship between an advertiser and a publisher, allowing advertisers to know exactly who is seeing their ad and in which context.

  8. Use Top App Categories to Reach Engaged Audiences

    The personal nature of the mobile device makes it ideal for reaching highly-specific audiences. Social, News, and Gaming are three of the app categories with the highest mobile user penetration, which make them effective for reaching a diverse base of engaged users.

  9. Reach Users of All Ages in Gaming Apps

    Gaming apps aren’t just for kids! Users of all ages turn to gaming apps to relax or challenge their friends, and with a 50% mobile user penetration in the US, gaming apps are an effective medium for reaching diverse audiences within the apps they love most.
