Whether you’re new to Apple’s advertising platforms or looking to refine your existing knowledge, this dictionary will serve as your go-to resource for navigating the complex world of Apple ads.
Why Apple Ads Matter in 2025
Apple’s advertising platforms have become increasingly important for marketers following the implementation of App Tracking Transparency (ATT) and privacy-focused changes in iOS. With over 1.8 billion active Apple devices worldwide, mastering Apple’s ad ecosystem is now essential for reaching valuable audiences while respecting user privacy.
Key Apple Ads Technical Definitions
App Store Connect
The platform where developers and marketers manage their apps and related advertising campaigns. App Store Connect serves as the central hub for configuring Apple Search Ads campaigns, analyzing performance metrics, and making adjustments to enhance campaign effectiveness.
Attribution API
Apple’s privacy-centric system for measuring ad effectiveness without tracking individual users across apps and websites. The Attribution API provides aggregated and delayed campaign data while protecting user privacy through techniques like data thresholding and random noise addition.
Attribution Window
The time period during which a conversion (like an app install or in-app purchase) can be attributed to a specific ad impression or click. Apple typically offers attribution windows ranging from 24 hours to 30 days.
Basic Campaign
An entry-level campaign type in Apple Search Ads that offers simplified setup and automated keyword selection. Basic campaigns are ideal for advertisers with limited experience or those looking for a more hands-off approach to campaign management.
Bid Amount
The maximum amount an advertiser is willing to pay for a user interaction (typically a tap) with their ad. Bid amounts in Apple Search Ads are specified as cost-per-tap (CPT) values and can be adjusted at the keyword or ad group level.
Campaign Hierarchy
The organizational structure of an Apple Search Ads campaign, consisting of campaigns, ad groups, and keywords. This hierarchical arrangement allows advertisers to organize targeting strategies logically and allocate budgets efficiently.
Creative Sets
Collections of screenshots and app previews that can be matched to specific keywords or audiences. Creative sets allow advertisers to customize the visual elements of their ads based on the search terms that triggered them, potentially increasing relevance and conversion rates.
Conversion Rate (CR)
The percentage of users who perform a desired action (like installing an app) after tapping on an ad. Conversion rate is a critical metric for evaluating ad effectiveness and optimizing campaign performance.
Discovery Campaigns
A campaign type that helps advertisers reach users who are browsing the App Store without searching for specific terms. Discovery campaigns utilize Apple’s machine learning algorithms to identify potential users based on their app usage patterns and preferences.
Daily Cap
The maximum daily spend limit for an Apple Search Ads campaign. Once this limit is reached, ads will stop showing until the next day, helping advertisers control their spending and maintain budget discipline.
Impression
An instance of an ad being displayed to a user in the App Store. Impressions are counted each time an ad is shown, regardless of whether users interact with it.
Install Volume
The number of app installations generated from an advertising campaign. This metric helps marketers understand the scale of user acquisition resulting from their ad spend.
Keyword Match Types
Configurations that determine how closely a user’s search query must match a targeted keyword for an ad to appear. Apple Search Ads offers three match types:
- Exact match: Triggers ads only when users search for the exact keyword phrase
- Broad match: Shows ads for searches related to the keyword, including misspellings and related terms
- Search match: Apple’s automated system that displays ads for relevant searches based on app metadata
Limit Ad Tracking (LAT)
A user privacy setting that restricts the use of the Identifier for Advertisers (IDFA) for tracking and ad targeting purposes. Users with LAT enabled can still be shown ads, but advertisers receive limited data about their interactions.
Lifetime Value (LTV)
The projected revenue a user will generate throughout their entire relationship with an app. Understanding LTV helps marketers determine appropriate customer acquisition costs and ROI thresholds.
Metadata
The textual information about an app, including its title, subtitle, description, and keywords. Metadata plays a crucial role in both organic App Store discovery and ad relevance in Apple Search Ads.
Managed Campaigns
Advanced Apple Search Ads campaigns (formerly known as Advanced campaigns) that offer granular control over keywords, bids, and audience targeting. These campaigns are suited for experienced advertisers who want maximum customization options.
Opt-in Rate
The percentage of users who allow tracking when prompted by the App Tracking Transparency (ATT) dialog. This metric has become crucial since iOS 14.5, as it directly impacts advertisers’ ability to track user activities across apps and websites.
Private Relay
Apple’s service that hides users’ IP addresses and browsing activity in Safari, affecting certain types of attribution and measurement. Advertisers need to adapt their strategies to account for this privacy-enhancing technology.
Product Page Optimization (PPO)
A feature that allows testing alternative versions of App Store product pages to identify the most effective elements for conversion. PPO results can inform both organic App Store presence and ad creative decisions.
Return On Ad Spend (ROAS)
The revenue generated for each dollar spent on advertising. ROAS is calculated by dividing the revenue attributed to ads by the cost of those ads, with higher values indicating more efficient campaigns.
Results Type
The specific conversion action being tracked for an Apple Search Ads campaign. Common results types include new downloads (installations), redownloads, and in-app events like purchases or subscriptions.
SkAdNetwork
Apple’s privacy-preserving attribution framework that allows advertisers to measure the effectiveness of their campaigns without tracking individual users. SkAdNetwork provides conversion data at the campaign level rather than the user level.
Search Terms
The actual queries that users enter in the App Store search bar. Analyzing search terms that trigger your ads can reveal valuable insights about user intent and help identify new keywords to target.
Tap-Through Rate (TTR)
The percentage of impressions that result in users tapping on an ad. TTR is calculated by dividing the number of taps by the number of impressions, with higher values indicating more engaging or relevant ads.
Target Cost-Per-Acquisition (tCPA)
A bidding strategy where advertisers set a target cost for acquiring a user who completes a specified action. Apple’s algorithms then automatically adjust bids to achieve this target cost on average.
User Acquisition Cost
The average expense required to acquire a new user through advertising. This metric helps marketers evaluate campaign efficiency and compare performance across different channels and strategies.

Best Practices for Apple Ads Success
Privacy-First Approach
Embrace Apple’s privacy framework rather than trying to work around it. Design campaigns that can succeed with aggregated data and delayed reporting by focusing on creative excellence and audience understanding.
Creative Optimization
Leverage Creative Sets to match visual assets with specific search terms or audiences. Test different screenshots and app previews to identify the combinations that drive the highest engagement and conversion rates.
Keyword Strategy
Develop a comprehensive keyword strategy that includes:
- Category terms related to your app’s functionality
- Competitor brand terms (where allowed by policies)
- Trending and seasonal search terms
- Long-tail phrases with high intent but lower competition
Budget Management
Allocate budget based on performance data, prioritizing keywords and audience segments with the strongest conversion rates and lowest acquisition costs. Implement dayparting to focus spending during hours with the highest engagement.
