Mastering SKAN 4: A Comprehensive Guide for Accelerating App Growth in the Era of Privacy First

SKAdNetwork or SKAN is a cornerstone in mobile advertising, especially in an era where user privacy is paramount. This framework by Apple allows advertisers to measure the success of their campaigns without compromising user data. SKAN operates without IDFA or other advertising ID and SKAN functions without the need for ATT consent.  This article aims to navigate the complexities of SKAN, providing insights into its history, attribution models, best practices, and a glimpse into the future.

A Brief History of SKAN

SKAN introduced by Apple, redefines ad attribution by prioritizing user privacy. Unlike traditional models that rely on user-level data, SKAN utilizes aggregated data, ensuring compliance with privacy norms. This approach not only aligns with the growing emphasis on user data protection but also challenges advertisers to adapt their strategies to this privacy-first paradigm.

In 2018, the foundations for SKAN were laid in iOS11, which introduced limitations on ad tracking to enhance user privacy. Apple began emphasizing user consent for tracking, requiring developers to request permission before accessing the Identifier for Advertisers (IDFA), a unique identifier associated with each iOS device.

In 2020 Apple announced more privacy updates for iOS 14, including App Tracking Transparency (ATT) Framework which required apps to request user permission explicitly before tracking their activities across apps and websites.

In 2021 was when Apple introduced SKAdNetwork (SKAN) to provide advertisers with a way to measure the success of their ad campaigns without compromising user privacy. Since then, multiple versions and updates to SKAN have been released, which will be discussed in greater detail further on in the article.

Understanding SKAN Attribution Models

Hierarchical Source Identifiers

Hierarchical source identifiers in SKAN help you pinpoint which campaign led to an app installation. This feature is particularly useful for marketers who run multiple campaigns across various platforms. It allows for a more granular understanding of campaign performance, aiding in more effective budget allocation.

However, it’s essential to note that while these identifiers provide more detailed data, they still adhere to Apple’s privacy guidelines. This means that the data is aggregated and does not compromise user privacy.

Coarse Conversion Values

Coarse conversion values are another feature that SKAN offers. These values give you a broader view of how your app is performing post-install. For example, you could track how often a user opens the app or makes an in-app purchase.

You can segment your audience based on these metrics to make the most of coarse conversion values. This segmentation can help you retarget campaigns or understand what features are most engaging for your users.

Multiple Conversions

SKAN allows tracking multiple conversions, offering a more dynamic view of user behavior. This is a step beyond traditional models that often focus on single conversion events like app installs or initial in-app purchases.

You can gain insights into user behavior over a more extended period by tracking multiple conversions. This data can be invaluable for long-term planning and understanding your users’ lifetime value (LTV).

Postbacks

A SKAN postback is a mechanism through which advertisers receive information about conversions attributed to their ad campaigns. This post-install data is crucial for analyzing campaign performance and optimizing future strategies.

SKAN 4.0

This iteration of SKAN brings a host of updates from its predecessors, delivering numerous advantages to advertisers. However, mastering the effective utilization of these enhancements poses a challenge for them.

Improved Measurement with Postbacks

In SKAN 4.0, advertisers can receive up to three postbacks, each based on a different activity window: 0-2 days, 3-7 days, and 8-35 days, respectively. This functionality enables advertisers to gain insights into user engagement with their app for a duration of up to 35 days after installation — a significant advancement compared to earlier SKAN versions.

The conversion values are now categorized as 'coarse-grained,' with distinctions of low, medium, or high to signify user engagement. This approach provides partial attribution data in cases where the privacy threshold is not met, allowing for the mapping of post-install behavior and obtaining a more comprehensive understanding compared to previous versions. With the introduction of multiple postbacks, advertisers can now acquire additional data, enhancing their ability to analyze early install signals. This evolution alleviates the need to excessively focus on the early funnel, offering a more nuanced and detailed perspective on user interactions with the app.

Crowd Anonymity Privacy Thresholds

Moving from a binary system to a tiered one, SKAN 4.0 introduces the term 'crowd anonymity' to replace 'privacy thresholds,' incorporating a four-tiered structure: 0, 1, 2, and 3. Apple assigns each install to a specific crowd anonymity tier, and based on this tier, can drop one or more of the following fields: fine-grained conversion value, coarse-grained conversion value, source identifier, or source app ID.

Source Identifier

In previous versions of SKAN, campaign IDs were restricted to two digits, allowing ad networks to assign numbers only within the 0-99 range. With SKAN 4.0, the campaign ID has undergone a rebranding to the 'source identifier' and can now accommodate up to four digits, resulting in a potential pool of up to 10,000 values. This enhancement provides ad networks with a substantial advantage, enabling better granularity in campaign dimension reporting. The Source ID serves as the new campaign name utilized by the network and in communication between the network and Apple.

The extended four-digit format of the Source ID allows for the encoding of more data compared to the previous two-digit limit, although this capability is not guaranteed due to crowd anonymity constraints. The demand for leveraging this feature primarily stems from the desire for improved creative modeling. Advertisers may not perceive a significant difference in their experience.

Best Practices for Optimizing SKAN Performance

Performance Metrics

Key Performance Indicators (KPIs) like Return On Ad Spend (ROAS), Lifetime Value (LTV), and Conversion Rate (CVR) are crucial for assessing your campaigns’ success. Monitoring these metrics can give you a clear picture of your campaigns’ effectiveness and areas for improvement.

Optimization Techniques

Optimization is an ongoing process. Techniques like A/B testing can be invaluable for fine-tuning your campaigns. For instance, you could run two ad creatives and compare their performance to see which is more effective.

The Future of SKAN

Upcoming Features and Updates

While Apple has not officially announced any upcoming features for SKAN, the community is rife with speculation. Features that enhance attribution while maintaining user privacy are highly anticipated.

SKAN 5.0

Although Apple has provided only a brief announcement of SKAN 5.0, a comprehensive presentation of this new SKAdNetwork version is still pending. Clues about the upcoming update have been scattered across various Apple presentations, leaving room for speculation until the full details are unveiled.

Notably, a significant shift in SKAN for app marketers appears to be the introduction of re-engagement measurement capabilities. While SKAN 5.0 may not fully support running re-engagement campaigns, similar to its predecessors, this development represents a notable advancement for the industry. Historically, advertisers faced a challenge as they had no means of accessing postbacks from user acquisition (UA) campaigns if the app was already installed on the user's device. The potential inclusion of re-engagement metrics in SKAN 5.0 hints at an evolving landscape where marketers may gain insights into user interactions beyond the initial installation, fostering a more comprehensive understanding of user engagement patterns.

Challenges and Opportunities

External factors like regulatory changes and market trends can pose challenges. However, they also offer opportunities for marketers willing to adapt. For instance, the rise of CTV advertising for apps presents a new avenue for user acquisition.

Preparing for the Future

Staying ahead in the rapidly evolving mobile advertising landscape requires constant learning and adaptation. Keep an eye on updates from Apple and be ready to pivot your strategies as needed.

Conclusion

SKAN has become an indispensable tool for mobile marketers, especially those focused on iOS. Its privacy-centric approach makes it a sustainable choice for the future. As SKAN evolves, keeping abreast of the latest developments will be key to maximizing your campaigns’ success.
