Mobile Attribution Accuracy | AppsFlyer

360° Mobile Attribution

Attribute Every Install To It's Source

What is Mobile Attribution?

Mobile attribution determines which campaigns, partners and channels delivered each app install. Marketers rely on these insights to measure and optimize their marketing performance for both user acquisition and retargeting campaigns.

Mobile app attribution utilizes a number of advanced technologies including real-time integrations with leading ad networks, universal deep linking, probabilistic modeling and secure postbacks for data sync across thousands of integrated providers. Each of these capabilities must be expertly developed and properly deployed in order to measure accurately. While this may sound complicated, a strong attribution platform will do the hard work for you, so you can focus on your marketing.

Mobile Attribution Vs Web Attribution

Mobile attribution is unlike traditional web attribution. On the internet, marketers use pixels and cookies to determine which marketing efforts drove each sign up, engagement or purchase. However, there are no cookies for mobile apps or devices. Reliable mobile app attribution requires the use of a variety of techniques and partnerships to accurately identify each user and attribute each install to the appropriate campaign, partner or channel.

Last-Touch Attribution, Multi-Touch Attribution and Fractional Attribution

Users will often interact with more than one promotion before installing an app. Therefore, mobile marketers need insights into their entire customer journey. Advertisers want to understand which promotions assisted each install, as well as which promotions successfully drove the install. AppsFlyer’s attribution technology provides marketers with the insights they need to understand every step in the customer journey leveraging last-touch, multi-touch, or fractional attribution models.

The primary AppsFlyer dashboard leverages last-touch attribution, attributing each install to the last promotion the user engaged with before installing the app. Oursoccer2-for-website-01 Assisted Installs Report and Raw Data Reports provide further insight into which networks contributed to or “assisted” each app install, delivering multi-touch attribution insights.

Some advanced marketers also leverage fractional attribution models. Fractional attribution models use a statistical breakdown to award an increasing percentage of the install to each promotion across the user-acquisition funnel. For example, using a fractional attribution model, a customer who saw three ads before an app install could be 20% attributed to the first network, 30% attributed to the second network and 50% attributed to the third network. Our robust Raw Data Reports contain the full customer journey, starting with first impression attribution (on supported networks) and on down the funnel, providing marketers with the data they need to optimize based on their preferred fractional attribution models.

How It Works

How AppsFlyer' Attribution Works

AppsFlyer’s mobile app user attribution is built on five key components:


Integrated Partners

Once initially configured, AppsFlyer will automatically recognize and attribute any install from any of our 7,000 integrated partners. With AppsFlyer, setting this up couldn’t be any easier. Just select your desired partner and follow the simple guide. We have done all of the hard work, and pre-configured available data to sync seamlessly between AppsFlyer and all integrated partners. Set it up once, and you’re good to go.


Certified Network Integrations

Some networks, such as Facebook, Google, Twitter, Snapchat and Pinterest, only offer mobile attribution to certified measurement partners. Any platform that is not a certified partner cannot accurately attribute installs on these platforms. On the backend, AppsFlyer’s custom server-to-server integrations with these platforms allow marketers to manage all of their conversion data, attributing each install at the user level, without needing to leave the AppsFlyer dashboard.


View-Through Attribution

AppsFlyer supports both impression-data collection and view-through attribution (when supported by the partner ad network). View-through attribution will attribute an install to a media source based an ad being viewed, even if it wasn’t clicked. 


Probabilistic Modeling

We first introduced our probabilistic modeling solution back in 2018, with the rollout of AppsFlyer’s adaptive lookback attribution. Probabilistic modeling leverages our scale and machine learning to measure campaign performance without compromising on privacy.  

Probabilistic modeling is completely anonymized to ensure the highest possible level of privacy. This form of attribution is based on probabilities, not ID matching, therefore lookback windows cannot be defined. The actual attribution window may be anywhere from zero to 24 hours.

Probabilistic modeling  has proven to work on all iOS versions in the past, and has already been tested and validated for iOS 14 by applying our probabilistic models on matches that have been previously made using a deterministic method proven in production to be >90% accurate.


OneLink™ Universal Deep Linking

AppsFlyer also supports user acquisition attribution from your owned and earned media. OneLink™ universal deep links are the ideal platform for attributing installs from your email marketing, SMS campaigns, social media, out of home media and more.

Best-In-Class Solutions

Data Accuracy

Mobile marketers rely on their analytics to inform their media spend and optimize their campaigns. At AppsFlyer, we take great pride in our data accuracy, offering marketers the best mobile attribution in the world. With over twelve billion dollars in annual ad spend measured, data accuracy is our number one priority.

In contrast, other providers have misappropriated pre-existing solutions in an attempt to deliver attribution insights. As a result, their data accuracy has proven disappointing to advertisers. For example, two attribution providers continue to use deep linking to attribute Facebook paid media installs. However, in order to determine which network delivered the final click and drove installs from Facebook media, the attribution provider must be part of Facebook’s Mobile Measurement Partner (MMP) program. Those not in the MMP program simply do not have access to “last click” data. As both of these attribution providers are not Facebook MMPs, they are unable to collect click data or accurately report on Facebook campaign performance. Many advertisers that have upgraded from these providers to AppsFlyer have been shocked at the accuracy of their previous data.

AppsFlyer’s multi-faceted technology stack including our deep integrations with leading platforms such as Facebook, Instagram, Google, YouTube, Pinterest and Snapchat ensure that every install is accurately attributed to the right source. There is no substitute for clean, accurate data.

Rock-Solid Attribution - Resolving Double Attribution and Misattribution

Many ad networks offer their own proprietary attribution solutions. Often, popular ad networks use their own proprietary attribution lookback window, resulting in double attribution and unfortunately, the misattribution of installs. This confusion limits mobile marketer’s abilities to effectively measure and optimize marketing campaigns.

In mobile advertising, a lookback window is the amount of time a network or attribution provider will look back when attributing an install. AppsFlyer allows you to configure your lookback windows per attribution link, so you can optimally measure every campaign. For example, using the default lookback window, a network with a 14 day lookback window will take credit for any user who clicked on one of their ads in the last 14 days. However, users often interact with multiple promotions before installing an app. A user may have engaged with this network’s ad, and then went on to view a video ad on a different network, and then installed the app after clicking on a social ad. In this case, all three networks could end up taking credit for the same install.

AppsFlyer’s configurable solutions will automatically resolve these discrepancies based on the advertiser’s preferred lookback windows. This provides better data clarity, and allows advertisers to tweak their attribution lookback windows with unparalleled flexibility and granularity.

Flexible Reattribution Windows

With AppsFlyer, advertisers can define their preferred re-attribution lookback window. A reattribution lookback window is a period of time after the original install during which a reinstall will not be reattributed to the new network. As a marketer, if I define a 90-day reattribution window, all installs that occur 89 days after the original install will not be re-attributed to the new source, but installs 91 days after the install will be attributed to the new media source.

Unlimited Data Retention

Regardless of the marketer-selected reattribution window, AppsFlyer retains all of your data forever. Whether you want this data in raw data reports or for aggregated calculations (e.g. lifetime value), AppsFlyer’s data retention gives your unlimited flexibility.
