In <strong>PPC<\/strong> environments\u2014where advertisers pay for clicks, impressions, or optimized events\u2014Cost Per App Open helps bridge the gap between \u201cad engagement\u201d and \u201cin-app activity,\u201d which is where real customer value is often created.<\/p>\n\n\n\n<p>Why does Cost Per App Open matter? Because many app businesses win or lose based on usage, not installs alone. Getting a user to re-engage, complete onboarding, browse products, or start a session can be more meaningful than simply adding an install to the tally. Used correctly, Cost Per App Open becomes a practical lever for optimizing campaign efficiency, diagnosing funnel friction, and aligning <strong>Paid Marketing<\/strong> spend with product growth.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Is Cost Per App Open?<\/h2>\n\n\n\n<p><strong>Cost Per App Open<\/strong> is the average advertising cost required to generate one tracked app-open event attributed to your ads. An \u201capp open\u201d typically means the app launches and records a session start (or a specific \u201capp open\u201d event) after a user clicks or views an ad, depending on your attribution settings.<\/p>\n\n\n\n<p>At its core, Cost Per App Open answers a simple business question: <strong>How efficiently can our ads drive people into the app experience?<\/strong> In app-first businesses\u2014commerce, fintech, gaming, marketplaces, media\u2014getting the user into the app is often the first step toward revenue, retention, and lifetime value.<\/p>\n\n\n\n<p>Where it fits in <strong>Paid Marketing<\/strong>:\n&#8211; It\u2019s a mid-funnel engagement metric that sits between top-funnel reach\/clicks and bottom-funnel conversions like purchases or subscriptions.\n&#8211; It can be used for both acquisition (new users opening for the first time) and re-engagement (existing users returning).<\/p>\n\n\n\n<p>Its role inside <strong>PPC<\/strong>:\n&#8211; In <strong>PPC<\/strong>, platforms can optimize delivery toward different objectives. When your goal is app opens, Cost Per App Open becomes a key efficiency KPI for those campaigns.\n&#8211; It helps compare campaigns that drive similar engagement outcomes even if they differ in bidding model (CPC vs CPM) or targeting approach.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why Cost Per App Open Matters in Paid Marketing<\/h2>\n\n\n\n<p>Cost Per App Open matters because it measures an outcome that is closer to product usage than clicks or impressions. A click may indicate curiosity; an app open indicates a stronger step toward engagement.<\/p>\n\n\n\n<p>From a strategic standpoint, Cost Per App Open helps you:\n&#8211; <strong>Quantify re-engagement efficiency<\/strong>: For many apps, reactivating existing users is cheaper than acquiring new ones. This metric lets you validate that assumption with data.\n&#8211; <strong>Spot funnel gaps<\/strong>: If clicks are strong but Cost Per App Open is high, it may indicate install friction, slow load time, broken deep links, or attribution\/measurement issues.\n&#8211; <strong>Align marketing and product<\/strong>: It creates a shared metric between growth marketers and product teams\u2014how often ads successfully bring users into an actionable app session.<\/p>\n\n\n\n<p>In competitive <strong>Paid Marketing<\/strong> environments, improving Cost Per App Open can create advantage by:\n&#8211; Reducing wasted spend on low-intent traffic\n&#8211; Helping you scale profitable audiences sooner\n&#8211; Providing a clearer optimization target than vanity engagement metrics<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Cost Per App Open Works<\/h2>\n\n\n\n<p>In practice, Cost Per App Open works as a measurement loop across ad delivery, attribution, and app analytics:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>\n<p><strong>Input \/ Trigger (ad exposure and interaction)<\/strong><br\/>\n   A user sees an ad (impression) and may click it. Depending on your setup, a view-through impression may also be eligible for attribution.<\/p>\n<\/li>\n<li>\n<p><strong>Processing (tracking and attribution)<\/strong><br\/>\n   Your app records an app-open event through an SDK or analytics instrumentation. An attribution system then decides whether that open is credited to a specific campaign based on rules such as click-through attribution windows, view-through windows, and last-touch logic.<\/p>\n<\/li>\n<li>\n<p><strong>Execution (campaign optimization decisions)<\/strong><br\/>\n   In <strong>PPC<\/strong> platforms, you (or the platform\u2019s optimization engine) adjust bids, budgets, creatives, and targeting to reduce Cost Per App Open while maintaining volume and quality. This may include optimizing for \u201capp opens\u201d as the campaign objective or optimizing toward deeper in-app events while still monitoring opens.<\/p>\n<\/li>\n<li>\n<p><strong>Output \/ Outcome (reported Cost Per App Open)<\/strong><br\/>\n   You compute <strong>Cost Per App Open = Spend \u00f7 Attributed App Opens<\/strong> for the selected time range, campaign scope, and attribution model. This becomes a comparable KPI across ad sets, audiences, creatives, and geographies.<\/p>\n<\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\">Key Components of Cost Per App Open<\/h2>\n\n\n\n<p>Accurate Cost Per App Open depends on several interlocking components:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Event definition<\/strong>: What counts as an \u201capp open\u201d? Session start, app foregrounding, or a custom event must be clearly defined and consistent.<\/li>\n<li><strong>Tracking instrumentation<\/strong>: Mobile analytics SDKs or first-party event tracking must reliably capture opens across devices and OS versions.<\/li>\n<li><strong>Attribution logic<\/strong>: Click-through vs view-through attribution, attribution windows, and last-touch vs multi-touch logic can materially change reported Cost Per App Open.<\/li>\n<li><strong>Deep linking and routing<\/strong>: If ads send users to the wrong screen\u2014or fail to open the app when installed\u2014app opens can drop and costs rise.<\/li>\n<li><strong>Audience strategy<\/strong>: Prospecting vs retargeting audiences behave differently; returning users often open faster and cheaper.<\/li>\n<li><strong>Creative and message match<\/strong>: Ads that promise one thing but deliver another may get clicks without opens (or opens without meaningful sessions).<\/li>\n<li><strong>Governance and ownership<\/strong>: Typically shared across growth marketing (campaigns), analytics (measurement), and engineering (SDKs, links). Clear ownership prevents \u201cmetric drift.\u201d<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Types of Cost Per App Open<\/h2>\n\n\n\n<p>Cost Per App Open doesn\u2019t have universally formal \u201ctypes,\u201d but in real <strong>Paid Marketing<\/strong> work there are important distinctions that change how you interpret it:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Acquisition-focused vs re-engagement-focused<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Acquisition Cost Per App Open<\/strong>: App opens from new users (often post-install). Useful when measuring how efficiently new users reach first session.<\/li>\n<li><strong>Re-engagement Cost Per App Open<\/strong>: App opens from existing or lapsed users. Often used in retention and win-back <strong>PPC<\/strong> campaigns.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Click-through vs view-through attributed<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Click-through Cost Per App Open<\/strong>: Opens attributed to an ad click. Typically higher intent and easier to validate.<\/li>\n<li><strong>View-through Cost Per App Open<\/strong>: Opens attributed after an impression without a click. Useful for understanding influence, but more sensitive to over-attribution and window settings.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Cold open vs deep-linked open (context-based)<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Cold open<\/strong>: The app opens to the default screen. This may indicate broken routing or missing deep link support.<\/li>\n<li><strong>Deep-linked open<\/strong>: The app opens to a specific screen (product page, offer, cart). Often improves downstream conversion and can justify a higher Cost Per App Open if quality rises.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Real-World Examples of Cost Per App Open<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Example 1: Retail app reactivation campaign<\/h3>\n\n\n\n<p>A retail brand runs <strong>Paid Marketing<\/strong> to re-engage users who installed the app but haven\u2019t opened it in 30 days. The <strong>PPC<\/strong> campaign uses a limited-time offer and deep links to a curated sale page. The team monitors Cost Per App Open by audience segment (7\u201314 days lapsed vs 15\u201330 vs 31+). They find that the 15\u201330 day segment delivers the lowest Cost Per App Open and the best purchase rate, so budget shifts toward that cohort.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Example 2: Fintech onboarding optimization<\/h3>\n\n\n\n<p>A fintech app observes strong ad CTR but weak growth in verified accounts. They use Cost Per App Open as a diagnostic metric: clicks are happening, but opens are lagging, indicating link routing issues on iOS. After fixing deferred deep links and reducing app launch time, attributed opens rise\u2014Cost Per App Open drops\u2014and downstream onboarding improves. Here, Cost Per App Open exposes a technical bottleneck affecting <strong>Paid Marketing<\/strong> efficiency.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Example 3: Gaming user acquisition vs engagement balance<\/h3>\n\n\n\n<p>A mobile game runs two <strong>PPC<\/strong> strategies: one optimized for installs, another optimized for in-app engagement events. The team still tracks Cost Per App Open as a comparable engagement KPI. Install-optimized campaigns deliver many installs but fewer opens (higher Cost Per App Open), while engagement-optimized campaigns deliver fewer installs but stronger open rates and better day-1 retention. The business chooses a blended approach based on profitability.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Benefits of Using Cost Per App Open<\/h2>\n\n\n\n<p>Used thoughtfully, Cost Per App Open provides tangible advantages:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>More relevant than clicks for apps<\/strong>: App opens better reflect real product usage than ad clicks alone.<\/li>\n<li><strong>Earlier signal than purchases<\/strong>: For long conversion cycles, Cost Per App Open can act as an early indicator of whether traffic is \u201cgetting into the product.\u201d<\/li>\n<li><strong>Improved budget efficiency<\/strong>: By comparing Cost Per App Open across audiences and creatives, teams can reallocate spend toward segments that actually enter the app.<\/li>\n<li><strong>Better user experience alignment<\/strong>: Monitoring opens alongside deep link success encourages cleaner landing experiences and fewer dead ends.<\/li>\n<li><strong>Cross-team clarity<\/strong>: It gives product, engineering, and marketing a shared KPI to improve the \u201cad \u2192 app\u201d pathway in <strong>Paid Marketing<\/strong> operations.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Challenges of Cost Per App Open<\/h2>\n\n\n\n<p>Cost Per App Open is useful, but it comes with real-world pitfalls:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Attribution ambiguity<\/strong>: View-through attribution and long windows can inflate attributed opens, especially for frequently used apps.<\/li>\n<li><strong>Platform privacy constraints<\/strong>: OS-level privacy changes can limit deterministic attribution and event-level reporting, affecting <strong>PPC<\/strong> optimization loops.<\/li>\n<li><strong>Event duplication or misfires<\/strong>: Poor session tracking can overcount opens (inflating performance) or undercount (making Cost Per App Open appear worse).<\/li>\n<li><strong>Not equal to value<\/strong>: An app open doesn\u2019t guarantee meaningful engagement. Some opens are accidental, brief, or driven by curiosity rather than intent.<\/li>\n<li><strong>Retargeting bias<\/strong>: Re-engagement audiences can make Cost Per App Open look \u201cgreat\u201d while incremental lift is small. Incrementality testing may be needed.<\/li>\n<li><strong>Fraud and low-quality traffic<\/strong>: Click spamming and device farms can create misleading patterns of attributed opens without real users.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Best Practices for Cost Per App Open<\/h2>\n\n\n\n<p>To make Cost Per App Open reliable and actionable in <strong>Paid Marketing<\/strong>, focus on both measurement hygiene and optimization discipline:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>\n<p><strong>Define \u201capp open\u201d precisely<\/strong><br\/>\n   Decide whether you\u2019re counting session start, foreground event, or a custom open event. Document it and keep it stable.<\/p>\n<\/li>\n<li>\n<p><strong>Segment reporting<\/strong><br\/>\n   Always break Cost Per App Open down by:\n   &#8211; New vs returning users\n   &#8211; Audience type (prospecting vs retargeting)\n   &#8211; OS (iOS vs Android)\n   &#8211; Geo and placement\n   This prevents averaging away critical differences.<\/p>\n<\/li>\n<li>\n<p><strong>Validate deep links and deferred deep links<\/strong><br\/>\n   Ensure installed users open directly in-app, and non-installed users reach the correct store flow and then the intended in-app destination after install.<\/p>\n<\/li>\n<li>\n<p><strong>Pair opens with quality metrics<\/strong><br\/>\n   Use Cost Per App Open with metrics like session duration, screens viewed, add-to-cart, or tutorial completion. This keeps <strong>PPC<\/strong> optimization aligned with business outcomes.<\/p>\n<\/li>\n<li>\n<p><strong>Use controlled attribution settings<\/strong><br\/>\n   Be deliberate with view-through attribution and windows. If you use view-through, compare it against click-through-only views to understand sensitivity.<\/p>\n<\/li>\n<li>\n<p><strong>Optimize creatives for the \u201cnext step\u201d<\/strong><br\/>\n   Creatives should set accurate expectations about what happens after the tap\u2014offer, content, and landing destination.<\/p>\n<\/li>\n<li>\n<p><strong>Run incrementality or holdout tests for retargeting<\/strong><br\/>\n   Low Cost Per App Open in retargeting can be misleading if many users would have opened anyway. Testing helps quantify true lift.<\/p>\n<\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\">Tools Used for Cost Per App Open<\/h2>\n\n\n\n<p>You don\u2019t need a single \u201cCost Per App Open tool,\u201d but you do need a reliable measurement stack that connects ad spend to app events:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Ad platforms and campaign managers<\/strong>: Where <strong>PPC<\/strong> bids, budgets, targeting, and objectives are set\u2014and where cost data originates.<\/li>\n<li><strong>Mobile attribution and measurement systems<\/strong>: Used to attribute app opens to campaigns and manage attribution windows and rules.<\/li>\n<li><strong>In-app analytics tools<\/strong>: Track sessions, app opens, funnels, retention, and user cohorts to assess quality beyond the initial open.<\/li>\n<li><strong>Tag management \/ event governance workflows<\/strong>: Help ensure event definitions are consistent across releases and teams.<\/li>\n<li><strong>Data warehouse and reporting dashboards<\/strong>: Combine spend, opens, and downstream events to compute Cost Per App Open alongside ROI metrics.<\/li>\n<li><strong>Fraud detection and traffic quality controls<\/strong>: Identify suspicious patterns that can distort Cost Per App Open in <strong>Paid Marketing<\/strong> reporting.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Metrics Related to Cost Per App Open<\/h2>\n\n\n\n<p>Cost Per App Open is most powerful when viewed in context. Common companion metrics include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>App Open Rate<\/strong>: Attributed app opens divided by clicks (or impressions). Helps isolate whether the issue is with ad engagement or app entry.<\/li>\n<li><strong>CTR (Click-Through Rate)<\/strong>: High CTR with poor opens can indicate broken links or mismatched expectations.<\/li>\n<li><strong>CPC \/ CPM<\/strong>: Underlying cost drivers in <strong>PPC<\/strong>; changes here directly influence Cost Per App Open.<\/li>\n<li><strong>Install rate and Cost Per Install (CPI)<\/strong>: Useful for acquisition campaigns; compare CPI vs Cost Per App Open to detect post-install drop-off.<\/li>\n<li><strong>Conversion rate to a key event<\/strong>: Purchases, signups, tutorial completion, add-to-cart\u2014validates whether opens translate to value.<\/li>\n<li><strong>Retention (D1\/D7\/D30)<\/strong>: Strong retention can justify a higher Cost Per App Open if users keep coming back.<\/li>\n<li><strong>ROAS and LTV<\/strong>: Ultimately, opens are a step toward revenue; long-term value determines sustainable <strong>Paid Marketing<\/strong> scale.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Future Trends of Cost Per App Open<\/h2>\n\n\n\n<p>Cost Per App Open is evolving as privacy rules, automation, and user expectations change:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>More modeled and aggregated measurement<\/strong>: With increasing privacy constraints, some reporting will rely on aggregated conversion signals and modeled attribution, impacting how precisely Cost Per App Open can be calculated.<\/li>\n<li><strong>AI-driven optimization toward post-open value<\/strong>: <strong>PPC<\/strong> systems are increasingly optimizing toward downstream events (e.g., purchase, retention) rather than just opens\u2014so opens become a diagnostic metric and a guardrail, not always the final objective.<\/li>\n<li><strong>Personalized deep links and creative variants<\/strong>: Better routing and personalization can increase open-to-value rates, changing what \u201cgood\u201d Cost Per App Open looks like.<\/li>\n<li><strong>Incrementality becoming standard<\/strong>: As remarketing grows, teams will use more lift testing to confirm that improved Cost Per App Open reflects real business impact.<\/li>\n<li><strong>Tighter collaboration between product and Paid Marketing<\/strong>: Faster app performance, cleaner onboarding, and stable event tracking will be treated as marketing efficiency work, not just engineering tasks.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Cost Per App Open vs Related Terms<\/h2>\n\n\n\n<p>Understanding nearby metrics prevents misalignment in <strong>Paid Marketing<\/strong> reporting:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Cost Per App Open vs Cost Per Install<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Cost Per Install<\/strong> measures the cost to generate an install.<\/li>\n<li><strong>Cost Per App Open<\/strong> measures the cost to generate an app session\/open.<br\/>\nInstalls can happen without meaningful usage; opens indicate the user actually entered the app experience.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Cost Per App Open vs Cost Per Acquisition<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Cost Per Acquisition<\/strong> usually refers to a deeper conversion (purchase, subscription, lead, verified signup).<\/li>\n<li>Cost Per App Open is earlier in the funnel and is best for engagement efficiency and diagnosing app-entry issues.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Cost Per App Open vs Cost Per Click<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Cost Per Click<\/strong> is the price of a click in <strong>PPC<\/strong>.<\/li>\n<li>Cost Per App Open is the price of a tracked app-open outcome.<br\/>\nIf CPC is stable but Cost Per App Open rises, the problem is often post-click (linking, store flow, app load time, attribution).<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Who Should Learn Cost Per App Open<\/h2>\n\n\n\n<p>Cost Per App Open is valuable across roles because it connects spend to real app usage:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Marketers and growth teams<\/strong>: To optimize <strong>Paid Marketing<\/strong> campaigns beyond clicks and installs and to improve traffic quality.<\/li>\n<li><strong>Analysts<\/strong>: To build accurate reporting, validate attribution, segment performance, and connect opens to retention and revenue.<\/li>\n<li><strong>Agencies<\/strong>: To provide clients with app-specific KPIs that explain performance and guide optimization in <strong>PPC<\/strong> accounts.<\/li>\n<li><strong>Business owners and founders<\/strong>: To understand whether ad spend is producing actual product engagement and to forecast unit economics.<\/li>\n<li><strong>Developers and product teams<\/strong>: To ensure tracking, deep links, and app performance support marketing outcomes and reduce wasted spend.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Summary of Cost Per App Open<\/h2>\n\n\n\n<p><strong>Cost Per App Open<\/strong> measures how much you spend to drive a tracked app open from advertising. It\u2019s an engagement-focused KPI that sits between top-funnel interactions and deeper conversions, making it especially useful in <strong>Paid Marketing<\/strong> for mobile apps. Within <strong>PPC<\/strong>, it helps teams evaluate whether campaigns are not only generating interest, but successfully bringing users into the app experience where retention and revenue happen. When paired with quality and downstream metrics, it becomes a practical tool for optimization, budgeting, and cross-team alignment.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Frequently Asked Questions (FAQ)<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">1) What is Cost Per App Open and how do you calculate it?<\/h3>\n\n\n\n<p>Cost Per App Open is calculated as <strong>total ad spend \u00f7 total attributed app opens<\/strong> for a defined scope (campaign\/ad set\/time period) and attribution setting. The key is that \u201capp open\u201d must be consistently tracked and correctly attributed.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2) Is Cost Per App Open more important than Cost Per Install?<\/h3>\n\n\n\n<p>It depends on the goal. If you\u2019re measuring acquisition volume, installs matter. If you care about real usage and re-engagement, Cost Per App Open often provides a clearer picture of whether your <strong>Paid Marketing<\/strong> is driving product engagement.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3) How can I lower Cost Per App Open in PPC campaigns?<\/h3>\n\n\n\n<p>Common levers include improving deep linking, tightening audience targeting, refreshing creatives to better match intent, excluding low-quality placements, and optimizing for downstream events while monitoring opens as a health metric in your <strong>PPC<\/strong> reporting.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4) Should I use click-through or view-through attribution for app opens?<\/h3>\n\n\n\n<p>Click-through attribution is usually more conservative and easier to validate. View-through can be useful for understanding influence, but it can inflate results depending on windows and user behavior. Compare both views and align with your measurement philosophy.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">5) What\u2019s a \u201cgood\u201d Cost Per App Open?<\/h3>\n\n\n\n<p>There isn\u2019t a universal benchmark. A \u201cgood\u201d Cost Per App Open depends on geography, platform, audience type, seasonality, and\u2014most importantly\u2014how app opens translate into retention and revenue for your business.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">6) Why do I see lots of clicks but few app opens?<\/h3>\n\n\n\n<p>Common causes include broken or missing deep links, slow app load times, app store friction, tracking\/SDK issues, or attribution mismatches. Investigate the post-click path and verify that opens are being recorded correctly.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">7) Can Cost Per App Open be misleading for retargeting?<\/h3>\n\n\n\n<p>Yes. Retargeted users may have opened the app anyway, which can make Cost Per App Open look very low without true incremental impact. Use holdouts or incrementality tests to validate that <strong>Paid Marketing<\/strong> is causing additional opens, not just capturing them.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Cost Per App Open is a performance metric used in **Paid Marketing** to understand how much you\u2019re paying to get someone to open your mobile app as a direct result of an ad interaction.
