It uses tracking models and technology to determine which touchpoint led a user to download and open an app for the first time.<\/span><\/p>\n<h2 data-path-to-node=\"7\">How Does App Install Attribution Work?<\/h2>\n<p data-path-to-node=\"8\">Unlike web attribution\u2014which relies heavily on cookies and UTM parameters\u2014mobile app attribution uses specialized technology to bridge the gap between ad networks, app stores, and the application itself.<\/p>\n<p data-path-to-node=\"9\">The standard flow within <a href=\"https:\/\/affisemmp.com\/\"><b data-path-to-node=\"9\" data-index-in-node=\"25\">Affise MMP<\/b><\/a> looks like this:<\/p>\n<ol start=\"1\" data-path-to-node=\"10\">\n<li>\n<p data-path-to-node=\"10,0,0\"><b data-path-to-node=\"10,0,0\" data-index-in-node=\"0\">The Touchpoint:<\/b> A user views an ad (impression) or interacts with it (click). The ad network sends this engagement data to the MMP.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"10,1,0\"><b data-path-to-node=\"10,1,0\" data-index-in-node=\"0\">The App Store:<\/b> The user is redirected to the Apple App Store or Google Play Store to download the application.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"10,2,0\"><b data-path-to-node=\"10,2,0\" data-index-in-node=\"0\">The First Launch:<\/b> The user opens the app for the first time. The <b data-path-to-node=\"10,2,0\" data-index-in-node=\"65\">Affise MMP SDK<\/b> instantly fires a signal, officially recording the install. <i data-path-to-node=\"10,2,0\" data-index-in-node=\"140\">(Note: Affise records the install at the exact moment of the first launch, not just when the app is downloaded).<\/i><\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"10,3,0\"><b data-path-to-node=\"10,3,0\" data-index-in-node=\"0\">The Match:<\/b> The MMP matches the first launch data with the preceding ad interaction using specific timeframes known as <b data-path-to-node=\"10,3,0\" data-index-in-node=\"118\">lookback windows<\/b> (e.g., a 7-day window for clicks).<\/p>\n<\/li>\n<\/ol>\n<h2 data-path-to-node=\"11\">Key Attribution Methods Used by Affise MMP<\/h2>\n<p data-path-to-node=\"12\">To provide precise attribution in a privacy-first ecosystem, Affise MMP uses a combination of deterministic and probabilistic methods tailored to iOS and Android environments:<\/p>\n<ul data-path-to-node=\"13\">\n<li>\n<p data-path-to-node=\"13,0,0\"><b data-path-to-node=\"13,0,0\" data-index-in-node=\"0\">Install Referrer (Android):<\/b> The primary and most accurate method for Android. When a user clicks a link and is directed to Google Play or the Huawei App Store, a unique referral string is passed to the app upon installation.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"13,1,0\"><b data-path-to-node=\"13,1,0\" data-index-in-node=\"0\">Device ID Matching:<\/b> A highly accurate, deterministic method that uses unique device identifiers (provided the user has granted consent to be tracked).<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"13,2,0\"><b data-path-to-node=\"13,2,0\" data-index-in-node=\"0\">SKAdNetwork (SKAN):<\/b> Apple\u2019s privacy-centric framework for iOS. Affise MMP integrates seamlessly with SKAN to track deterministic, aggregated campaign data without relying on user-level identifiers.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"13,3,0\"><b data-path-to-node=\"13,3,0\" data-index-in-node=\"0\">Probabilistic Modeling:<\/b> When direct identifiers are unavailable, this method uses temporary, non-unique device characteristics (such as OS version, device type, and network data) to match users to ad clicks in real time.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"13,4,0\"><b data-path-to-node=\"13,4,0\" data-index-in-node=\"0\">Pre-install Attribution:<\/b> Attributes users who open an app that was pre-loaded onto their device by the manufacturer (OEM). If the user hasn&#8217;t interacted with other ads prior to launch, the pre-install takes top attribution priority.<\/p>\n<\/li>\n<\/ul>\n<h2 data-path-to-node=\"14\">The Affise MMP Attribution Model: The Waterfall Approach<\/h2>\n<p data-path-to-node=\"15\">To prevent ad networks from unfairly claiming credit for the same user, Affise MMP utilizes a strict priority system\u2014or \u00abwaterfall format\u00bb\u2014to ensure a single source of truth:<\/p>\n<ul data-path-to-node=\"16\">\n<li>\n<p data-path-to-node=\"16,0,0\"><b data-path-to-node=\"16,0,0\" data-index-in-node=\"0\">Clicks over Impressions:<\/b> If a user views an ad (impression) but later clicks a different ad before installing, the click always has a higher priority for attribution.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"16,1,0\"><b data-path-to-node=\"16,1,0\" data-index-in-node=\"0\">Last-Touch Priority:<\/b> When all other factors are equal, the last click or impression before the install gets the primary credit.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"16,2,0\"><b data-path-to-node=\"16,2,0\" data-index-in-node=\"0\">Assisted Installs (Multi-Interaction):<\/b> If multiple networks drove touchpoints before the final install, the last touch gets the main credit. However, Affise MMP tracks the prior interactions as <i data-path-to-node=\"16,2,0\" data-index-in-node=\"194\">Assisted Installs<\/i>, giving marketers visibility into the full customer journey.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"16,3,0\"><b data-path-to-node=\"16,3,0\" data-index-in-node=\"0\">Reinstalls &amp; Re-attribution:<\/b> If a user deletes an app and installs it again later, it is regulated by a specific re-attribution window. This prevents networks from getting paid for a \u00abnew\u00bb install when it is actually a returning user.<\/p>\n<\/li>\n<\/ul>\n<h2 data-path-to-node=\"17\">Why Do Marketers Need an MMP for App Install Attribution?<\/h2>\n<p data-path-to-node=\"18\">Relying on self-reporting ad networks (like Meta, Google, or TikTok) to measure their own success leads to fragmented data and wasted budget. Implementing App Install Attribution through Affise MMP offers three distinct advantages:<\/p>\n<ol start=\"1\" data-path-to-node=\"19\">\n<li>\n<p data-path-to-node=\"19,0,0\"><b data-path-to-node=\"19,0,0\" data-index-in-node=\"0\">Accurate ROAS Calculation:<\/b> By directly connecting ad spend to actual installs and downstream revenue, marketers can calculate their true Return on Ad Spend (ROAS).<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"19,1,0\"><b data-path-to-node=\"19,1,0\" data-index-in-node=\"0\">Eliminating Double Counting:<\/b> Without an MMP, multiple ad networks might claim credit for a single install. Affise MMP deduplicates this data, ensuring you only pay for an install once.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"19,2,0\"><b data-path-to-node=\"19,2,0\" data-index-in-node=\"0\">Fraud Prevention:<\/b> Advanced attribution logic helps identify and filter out fake installs, click spamming, and SDK spoofing, ensuring budgets are spent on real, high-quality users.<\/p>\n<\/li>\n<\/ol>\n<p>For a head-to-head look at how Affise MMP compares to Airbridge and Tenjin, including pricing and feature breakdowns, see our <a href=\"https:\/\/affisemmp.com\/blog\/affise-mmp-vs-airbridge-vs-tenjin-pricing-and-feature-comparison\/\">full comparison<\/a>.<\/p>\n","protected":false},"template":"","meta":{"_acf_changed":false,"content-type":"","inline_featured_image":false},"class_list":["post-58454","glossary-term","type-glossary-term","status-publish","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.2 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>App Install Attribution Definition: Mobile Marketing Glossary<\/title>\n<meta name=\"description\" content=\"What is App Install Attribution?
