It attributes installs and certain re-engagements with signed postbacks, instead of giving advertisers a person-level trail. That changes what a user acquisition team can expect from an iOS report and how it should compare campaigns.<\/p>\n<p>Apple describes App AdAttributionKit as a framework that builds on SKAdNetwork. It can measure the campaign behind an install without tracking people or devices across other companies&#8217; apps. The result is useful, but conditional fields and delayed reporting mean it should be read as an aggregate measurement system, not a click log.<\/p>\n<nav aria-label=\"Table of contents\">\n<ul>\n<li><a href=\"#definition\">What AdAttributionKit measures<\/a><\/li>\n<li><a href=\"#postbacks\">What an attribution postback can contain<\/a><\/li>\n<li><a href=\"#sample\">How to read a sample cohort<\/a><\/li>\n<li><a href=\"#setup\">What to check before using the data<\/a><\/li>\n<li><a href=\"#reporting\">How to use it in reporting<\/a><\/li>\n<\/ul>\n<\/nav>\n<h2 id=\"definition\">AdAttributionKit for apps measures app ad outcomes without user-level tracking<\/h2>\n<p>App AdAttributionKit connects an ad interaction to an app outcome when the privacy rules permit it. Apple says it supports install attribution and, on supported system versions, re-engagement measurement. A click-through install can be attributed when someone taps an ad, reaches the app product page, installs, and later opens the app. Apple states that the click-through lookback window is 30 days. View-through attribution is available for an ad view followed by an install within 24 hours.<\/p>\n<p>The framework applies an attribution rule across participating networks. If a person taps ads from several registered networks before installing, the most recent attributable click receives credit. If a relevant network is not registered, the result can reflect the last known interaction from a participating network. That is why a report should name the networks covered before anyone treats its totals as a full media-mix answer.<\/p>\n<p>It is not a replacement for every measurement input. Cost, creative labels, campaign naming, purchases, and refund data still need their own reliable sources. For Android campaigns, the <a href=\"https:\/\/roasit.com\/blog\/google-play-install-referrer-setup\/\">Google Play Install Referrer setup<\/a> has a different data path. On iOS, the framework is designed to preserve privacy by limiting postback detail and delaying delivery.<\/p>\n<figure><img loading=\"lazy\" decoding=\"async\" width=\"2048\" height=\"1536\" class=\"wp-image-47\" src=\"https:\/\/roasit.com\/blog\/wp-content\/uploads\/2026\/10\/adattributionkit-flow.jpeg\" alt=\"AdAttributionKit mobile attribution flow\" srcset=\"https:\/\/roasit.com\/blog\/wp-content\/uploads\/2026\/10\/adattributionkit-flow.jpeg 2048w, https:\/\/roasit.com\/blog\/wp-content\/uploads\/2026\/10\/adattributionkit-flow-300x225.jpeg 300w, https:\/\/roasit.com\/blog\/wp-content\/uploads\/2026\/10\/adattributionkit-flow-1024x768.jpeg 1024w, https:\/\/roasit.com\/blog\/wp-content\/uploads\/2026\/10\/adattributionkit-flow-768x576.jpeg 768w, https:\/\/roasit.com\/blog\/wp-content\/uploads\/2026\/10\/adattributionkit-flow-1536x1152.jpeg 1536w\" sizes=\"auto, (max-width: 2048px) 100vw, 2048px\" \/><figcaption>A sample flow from an ad interaction to an aggregated postback.<\/figcaption><\/figure>\n<h2 id=\"postbacks\">AdAttributionKit postbacks contain campaign signals, but some fields can be absent<\/h2>\n<p>Apple&#8217;s <a href=\"https:\/\/developer.apple.com\/app-store\/ad-attribution\/\" target=\"_blank\" rel=\"noopener\">App AdAttributionKit overview<\/a> lists the types of information that can appear in an install or re-engagement postback. These include an advertised item identifier, conversion type, source identifier, and conversion values. A publisher item identifier can also be available. The last two are conditional, so a blank field does not automatically mean the campaign failed.<\/p>\n<p>Crowd anonymity controls how much detail the framework can send. When conversion volume is low, a postback may omit data that would make a small group easier to identify. As volume grows, the report can contain more information while still applying Apple&#8217;s privacy safeguards. A dashboard should therefore separate three states: a reported value, an intentionally unavailable value, and a genuinely missing ingestion record.<\/p>\n<p>Conversion values are where the product team decides what early user quality means. Apple says an advertiser can configure up to 64 signals of user value for an install notification. A subscription app might reserve values for trial start, paid conversion, and an early renewal signal. A game might assign them to tutorial completion, first purchase, or a retention milestone. The schema needs to be stable long enough for cohort comparisons to make sense.<\/p>\n<p>The existing guide to <a href=\"https:\/\/roasit.com\/blog\/skadnetwork-conversion-values\/\">SKAdNetwork conversion values<\/a> covers the discipline of mapping early behavior to useful reporting buckets. The same rule applies here: choose events that help decide whether a campaign deserves another dollar, rather than events that merely happen often.<\/p>\n<figure><img loading=\"lazy\" decoding=\"async\" width=\"2048\" height=\"1536\" class=\"wp-image-49\" src=\"https:\/\/roasit.com\/blog\/wp-content\/uploads\/2026\/10\/adattributionkit-privacy.jpeg\" alt=\"AdAttributionKit privacy threshold illustration\" srcset=\"https:\/\/roasit.com\/blog\/wp-content\/uploads\/2026\/10\/adattributionkit-privacy.jpeg 2048w, https:\/\/roasit.com\/blog\/wp-content\/uploads\/2026\/10\/adattributionkit-privacy-300x225.jpeg 300w, https:\/\/roasit.com\/blog\/wp-content\/uploads\/2026\/10\/adattributionkit-privacy-1024x768.jpeg 1024w, https:\/\/roasit.com\/blog\/wp-content\/uploads\/2026\/10\/adattributionkit-privacy-768x576.jpeg 768w, https:\/\/roasit.com\/blog\/wp-content\/uploads\/2026\/10\/adattributionkit-privacy-1536x1152.jpeg 1536w\" sizes=\"auto, (max-width: 2048px) 100vw, 2048px\" \/><figcaption>Privacy thresholds can change which fields arrive in an attribution postback.<\/figcaption><\/figure>\n<h2 id=\"sample\">Read a sample cohort as an aggregate decision tool<\/h2>\n<p>This table is a sample made for this article. It shows how a UA team might compare two campaigns after postbacks and revenue events are aggregated. It does not represent a benchmark or a promised outcome.<\/p>\n<div class=\"rb-table-scroll\"><table>\n<thead>\n<tr>\n<th>Campaign<\/th>\n<th class=\"num\">Attributed installs<\/th>\n<th class=\"num\">Known conversion values<\/th>\n<th class=\"num\">Day-7 net revenue<\/th>\n<th class=\"num\">Spend<\/th>\n<th class=\"num\">Day-7 cohort ROAS<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Video prospecting<\/td>\n<td class=\"num\">1,200<\/td>\n<td class=\"num\">780<\/td>\n<td class=\"num\">$2,160<\/td>\n<td class=\"num\">$3,000<\/td>\n<td class=\"num\">72%<\/td>\n<\/tr>\n<tr>\n<td>Search intent<\/td>\n<td class=\"num\">620<\/td>\n<td class=\"num\">510<\/td>\n<td class=\"num\">$1,550<\/td>\n<td class=\"num\">$1,600<\/td>\n<td class=\"num\">96.9%<\/td>\n<\/tr>\n<\/tbody>\n<\/table><\/div>\n<p>The calculation is simple: Day-7 cohort ROAS equals Day-7 net revenue divided by spend. For the search campaign, $1,550 divided by $1,600 equals 0.96875, or 96.9%. The decision is not to declare the campaign a winner after one ratio. Check its spend, cohort age, geography, and the share of postbacks with useful conversion information. A campaign with lower volume can look cleaner because there are fewer records to inspect.<\/p>\n<p>Keep attributed installs separate from total installs. Also keep unknown conversion values separate from zero-value users. Mixing those groups turns a privacy threshold into a false performance result. A cohort report needs clear definitions for revenue, refund treatment, and the event window before it can guide a budget shift.<\/p>\n<h2 id=\"setup\">Set up the measurement plan before the first campaign scales<\/h2>\n<ol>\n<li>Confirm which ad networks are registered and participating. Apple notes that attribution can only occur among integrated networks, so this list belongs in the reporting documentation.<\/li>\n<li>Choose conversion values that reflect actions worth paying for. Keep the mapping short enough that analysts can explain each bucket.<\/li>\n<li>Store every postback and its arrival time. Delivery delay makes same-day reporting unreliable for this measurement stream.<\/li>\n<li>Join postback data to spend with consistent campaign identifiers. Do not assume a campaign name in one platform automatically maps to another.<\/li>\n<li>Build a report that labels conditional fields. An empty publisher identifier and a failed pipeline check are different problems.<\/li>\n<\/ol>\n<p>Apple&#8217;s <a href=\"https:\/\/ads.apple.com\/app-store\/help\/attribution\/0093-adattributionkit-to-measure-performance\" target=\"_blank\" rel=\"noopener\">measurement guide<\/a> explains that crowd anonymity and time delays are part of the design. That is a reporting constraint, not a reason to abandon the data. It means daily pacing should use the freshest suitable signals, while cohort evaluation waits for the window that answers the budget question.<\/p>\n<p>For teams also running re-engagement campaigns, keep an install cohort and a returning-user cohort apart. A redownload or re-open represents a different economic question than a first install. The same distinction matters when comparing this framework with <a href=\"https:\/\/roasit.com\/blog\/deferred-deep-links-mobile\/\">deferred deep link measurement<\/a>, where the reporting goal often starts with the experience after install.<\/p>\n<h2 id=\"reporting\">Use AdAttributionKit data alongside cost and revenue, not as a standalone score<\/h2>\n<p>AdAttributionKit for apps gives a privacy-preserving view of which registered networks contributed to installs and later outcomes. It does not contain every answer a UA manager needs. A useful weekly review joins postbacks to cost, then compares cohorts at the same age. Revenue should reflect the business definition used for decisions, including refunds or store deductions where relevant.<\/p>\n<p>Start with one narrow question for each report: Which campaign reached an acceptable Day-7 return? Which source generated enough qualified early actions to keep testing? Which campaigns have too little privacy-permitted detail for a confident call? That framing keeps aggregate attribution honest and makes the limits visible.<\/p>\n<p>For related iOS measurement reading, visit the <a href=\"https:\/\/roasit.com\/blog\/category\/skadnetwork-and-privacy\/\">SKAdNetwork and Privacy category<\/a>. Keep the raw postbacks, the conversion-value map, and the cohort calculation together. That gives the team an audit trail when a budget decision needs to be revisited.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Learn how AdAttributionKit for apps reports privacy-preserving install and re-engagement outcomes for iOS campaign decisions.<\/p>\n","protected":false},"author":2,"featured_media":48,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[4],"tags":[16,14,15],"class_list":["post-50","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-skadnetwork-and-privacy","tag-ios","tag-mobile-attribution","tag-skadnetwork"],"_links":{"self":[{"href":"https:\/\/roasit.com\/blog\/wp-json\/wp\/v2\/posts\/50","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/roasit.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/roasit.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/roasit.com\/blog\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/roasit.com\/blog\/wp-json\/wp\/v2\/comments?post=50"}],"version-history":[{"count":1,"href":"https:\/\/roasit.com\/blog\/wp-json\/wp\/v2\/posts\/50\/revisions"}],"predecessor-version":[{"id":51,"href":"https:\/\/roasit.com\/blog\/wp-json\/wp\/v2\/posts\/50\/revisions\/51"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/roasit.com\/blog\/wp-json\/wp\/v2\/media\/48"}],"wp:attachment":[{"href":"https:\/\/roasit.com\/blog\/wp-json\/wp\/v2\/media?parent=50"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/roasit.com\/blog\/wp-json\/wp\/v2\/categories?post=50"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/roasit.com\/blog\/wp-json\/wp\/v2\/tags?post=50"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
