Mobile In-App FAQs
Transparency is key to successful campaigns. Leverage these Frequently Asked Questions (FAQs) to find out what you need to know about running mobile and in-app campaigns that drive results.
Mobile and in-app advertising refers to delivering ads within mobile apps or on mobile-optimized web pages.
Fraud tactics like SDK spoofing and click injection can drain ad budgets and skew performance data.
Contextual targeting ensures ads are relevant to the app’s content, leading to higher engagement and user satisfaction.
IAS uses SDK integrations to track ad impressions and ensure compliance with viewability standards.
Challenges include the prevalence of user-generated content, limited screen space, and fast-changing app landscapes.
Mobile ads are designed for smaller screens, focus on shorter engagement times, and often use formats like interstitials and rewarded videos.
Mobile in-app viewability refers to the measurement of how visible ads are within mobile apps. It tracks whether users actually see an ad and for how long, helping advertisers understand the effectiveness of their mobile advertising efforts. Mobile in-app viewability is important because it provides insights into whether ads reach their intended audience and engage users effectively. High viewability rates indicate that more people see the ad, which often correlates with better ad performance and a higher return on investment (ROI).
Mobile in-app viewability measures ad visibility within apps, while mobile web viewability applies to ads shown on mobile browsers. In-app viewability often benefits from more controlled environments and placements, while mobile web ads face challenges like ad blockers and layout changes.
