Since the launch of App Tracking Transparency (ATT) in iOS 14.5, SKAN has become the primary attribution framework for most advertisers on iOS.<\/p>\n\n\n\n<p>Now, with <strong>SKAN 4.0<\/strong>, Apple has significantly expanded the model\u2014bringing new opportunities for marketers who can adapt their strategies to this evolving, privacy-first world.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>What\u2019s New in SKAN 4.0<\/strong><\/h3>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Multiple Postbacks for Better Insight<\/strong><strong><br><\/strong> Previously, SKAN only sent one postback per install, containing limited information about early user behavior. SKAN 4.0 now offers <strong>up to three postbacks<\/strong> over time:<br>\n<ul class=\"wp-block-list\">\n<li><strong>Postback 1:<\/strong> 0\u20132 days after install<br><\/li>\n\n\n\n<li><strong>Postback 2:<\/strong> 3\u20137 days after install<br><\/li>\n\n\n\n<li><strong>Postback 3:<\/strong> 8\u201335 days after install<br><\/li>\n<\/ul>\n<\/li>\n\n\n\n<li>This allows advertisers to capture more data about user engagement and monetization across the first month\u2014crucial for apps with longer onboarding or monetization cycles.<br><\/li>\n\n\n\n<li><strong>Coarse Conversion Values<\/strong><strong><br><\/strong> In addition to detailed \u201cfine\u201d conversion values, SKAN 4.0 introduces \u201ccoarse\u201d values (low, medium, high). This lets advertisers still get directional performance insights even when user privacy thresholds prevent sharing detailed data.<br><\/li>\n\n\n\n<li><strong>Crowd Anonymity Tiers<\/strong><strong><br><\/strong> Apple\u2019s \u201ccrowd anonymity\u201d model determines how much data you receive based on the volume of installs per campaign. Higher install volumes unlock more detailed reporting. SKAN 4.0 now uses tiers that allow for partial data even in lower-volume scenarios.<br><\/li>\n\n\n\n<li><strong>Web-to-App Attribution<\/strong><strong><br><\/strong> SKAN 4.0 now supports tracking conversions from Safari-based web ads to App Store installs\u2014opening new retargeting and cross-channel possibilities.<br><\/li>\n\n\n\n<li><strong>Hierarchical Source Identifiers<\/strong><strong><br><\/strong> Marketers can now use <strong>hierarchical campaign IDs<\/strong> (up to 4 digits) to encode more granular information about placements, audiences, or creative while still respecting privacy thresholds.<br><\/li>\n<\/ol>\n\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>How to Adapt Your Media Buying Strategies<\/strong><\/h3>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Optimize for Early Engagement Signals<\/strong><strong><br><\/strong> With multiple postbacks, you need to identify which in-app actions within days 0\u20132 correlate with long-term value. Optimizing campaigns for those early indicators will help you make faster, more informed bidding decisions.<br><\/li>\n\n\n\n<li><strong>Scale to Unlock More Data<\/strong><strong><br><\/strong> Because crowd anonymity still limits granularity at low volumes, consolidating spend into fewer campaigns or creative groups can help push installs over the privacy threshold\u2014unlocking fine conversion values and more actionable insights.<br><\/li>\n\n\n\n<li><strong>Use Coarse Values for Testing<\/strong><strong><br><\/strong> Coarse values are less precise, but they still allow you to compare creative performance and audience segments when you can\u2019t reach fine-value thresholds. Treat them as a \u201cdirectional compass\u201d rather than a precision instrument.<br><\/li>\n\n\n\n<li><strong>Leverage Web-to-App Flows<\/strong><strong><br><\/strong> If your brand has strong mobile web traffic, integrating SKAN\u2019s web-to-app capabilities can help recapture lost attribution from Safari and expand retargeting options.<br><\/li>\n\n\n\n<li><strong>Invest in Predictive Modeling<\/strong><strong><br><\/strong> With longer feedback loops, machine learning models that predict LTV from early signals become more important. Partner with MMPs or UA platforms that specialize in SKAN-compliant modeling.<br><\/li>\n<\/ol>\n\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Final Thoughts<\/strong><\/h3>\n\n\n\n<p>SKAN 4.0 is a step forward for iOS app marketing\u2014it delivers more data while maintaining Apple\u2019s privacy standards.
