IOS 14 And IDFA: What Advertisers & Publishers Need To Know. Deep Analysis that can change your Ad game

IOS 14 And IDFA: What Advertisers & Publishers Need To Know. Deep Analysis that can change your Ad game

At its yearly Worldwide Developers Conference (WWDC) this year, Apple disclosed the most recent variant of its Mobile working framework, iOS 14, among different declarations. However, in the realm of Ad tech and Mobile in-app purchasing, the greatest news from WWDC this year is related to its ID for Advertisers (IDFA). 

In particular, Apple is presently requiring each application to pick up client authorization to gather and utilize its IDFA for promoting purposes. Applications can just request opt-in permission once, and the look and language of the ask are largely set, and all iOS apps will be required to ask their users on iOS 14 and greater. 

Some state just 15% or less will opt-in, while more liberal assessments see 75% opt-in rates for some applications. Taking into account that around 30% of iOS gadget proprietors in the U.S. have Limit Ad Tracking turned on despite the fact that it’s somewhat covered up, most would agree that at any rate half of those utilizing iOS 14-controlled gadgets will quit – if not more. 

Obviously, rather than across the board approach of LAT(Limit Ad Tracking), clients should select in for pretty much every application on their cell phone once iOS 14 is introduced. This may imply that opt-in rates post iOS 14 will be lower than present-day LAT pick in rates.

As a result, how advertisers and publishers use IDFA for scalable user-level ad targeting and personalization will be impacted.  

What is LAT(Limit Ad Tracking)?

Since you will come across LAT(limit Ad Tracking) many times while reading the article so here is all you need to know about LAT(limit Ad Tracking)

Limit Ad Tracking is a setting on Apple’s mobile operating system that prevents marketers from seeing and tracking customers or users by their device-specific Identifier for Advertising, or IDFA. On Android, clicking to opt-out of interest-based advertising or ads personalization accomplishes the same task.

How An Advertiser’s Life May Change Post IOS 14 launch

Before we visualize, it assists with seeing how the IDFA is presently used. It plays a major role in identity, attribution, efficiency, audience targeting, frequency capping, and in fighting fraud, among other areas. 

The IDFA is used for three main purposes by advertisers: 

IDFA Uses for advertisers

  1. The first is personality/focusing on. Just put this is how advertisers perceive users in the ecosystem and target or retarget them in the quest for their advertising objectives. Most, if not all, campaigns focus on a particular arrangement of users, normally dependent on properties, liking, and different scores based on the head of an IDFA client diagram. While the absence of an IDFA eliminates all capacity to construct these sorts of user attributes, focusing on dependent on client traits (logical or geo) instead of only an identifier may keep on being upheld.
  2. The second is efficiency and value management. The IDFA is used to power efficiencies driving technology such as frequency capping, ad rotation, dynamic creative optimization, and pricing/prediction. Without IDFA, it is also difficult for demand-side platforms (DSPs), ad networks, and exchanges that advertisers work with to enforce a frequency cap on user impressions to optimize campaigns efficiently. We expect typical campaigns to move from using IDFA-based optimization to an in-session or non-persistent ID-based frequency capping. While not perfect, this prevents wastage of impressions on the same user. 
  3. The third is measurement and attribution. The IDFA is the most critical component of the measurement chain, powering multi-touch attribution, last-click attribution, last-view attribution, etc., and is the basis on which all mobile media is measured today. Each of these aspects is impacted significantly by iOS 14. Additionally, depending on the intent of the campaign (upper funnel/branding vs. mid-funnel/prospecting vs. bottom-funnel/user acquisition and retargeting), a different level of cardinality is present in the issues presented, as well as the solution. 

In bottom-funnel advertising campaigns, the impact of this change is profound. Without IDFA, deterministic, user-level attribution for any app install is next to impossible. While Apple’s SKAdNetwork acts as a privacy-compliant substitute, it is limited by its current capabilities. The catch is that advertisers may only receive aggregated install data that will not be useful in understanding and optimizing for lifetime vale (LTV) (unlike LTV/user-level data provided by mobile measurement platforms today). 


Moving Past IDFA As The Single Source Of Truth In Mobile Advertising

It is advantageous to take note of that IDFA is only one information signal among numerous that are as of now used in Mobile in-application advertising. Going ahead, we anticipate that more accentuation should be put on probabilistic and relevant information signals, among different wellsprings of information.

So what different wellsprings of information will advertisers keep on approaching once iOS 14 is live on most Apple gadgets? The companies having SDK will keep on get-together significant information where conceivable and where permitted. First-party information, regardless of whether from the publisher or another source, will at present be accessible (and significant) as well. Notable benchmarks and results can be exceptionally lighting up too.

For example, brand advertisers can hope to keep on depending on plenty of relevant signs that companies having SDK, with its enormous in-application SDK impression can welcome ready. This incorporates advancing offer solicitations with application metadata like substance classification or page content grouping (according to standard IAB scientific categorization), gadget signals (like equipment form, IPv6, network speed, sound settings, and so forth.), segment data based sections, and area data (both exact and coarse, as allowed by the client on iOS 14).

It’s likewise imperative to take note of that iOS 14 doesn’t affect IDV, which is the Publisher specific user ID common to all App Store applications over the publisher. Also, obviously, the normal deterioration of IDFA could imply that outsider gadget diagram identifiers like those from LiveRamp and Tapad assume a bigger function in the versatile in-application promoting biological system. These sorts of signs could be utilized at scale for promoting viability, with solid match rates.

We Know you must be wondering what is SDK???

What is a mobile SDK?

SDK software development kit

A mobile software development kit, or SDK, is a bit of code that lets mobile applications interface with outsider administrations and innovations. By integrating mobile SDK, developers can get to various apparatuses like in analytics or re-engagement, or connect to ad networks to run in-app ads.

In contrast to APIs, which act more as extensions, SDKs take into account a more extravagant arrangement of innovative abilities by being all the more profoundly inserted in an application, conveying a more far-reaching set of apparatuses. These may include libraries, code samples, and guides that can help developers build better applications.

What App Publishers Need To Know 

IDfa opt-in opt-out rate

With iOS 14, publishers and developers are needed to give a reason string that is shown to users through a pop-up and clarifies why they would need to track a particular user. MBS Info Solution completely bolsters this change being presented in iOS 14 in the soul to put the security of users first and giving individuals more authority over the manner in which their own information is overseen.

While we don’t yet have any impartial information to benchmark or gauge the opt-in rates yet, all things considered, the number of users who opt-in will be low for applications in iOS 14. In this feasible situation, actualizing important worth trade with the users as an end-result of information ought to be a need for publishers.

While IDFA was all around acknowledged for focusing because of its scale, there are other special and close deterministic signs which can be similarly powerful for such use cases. This incorporates IDV (the remarkable gadget identifier accessible to publishers over their applications on a given gadget), autonomous outsider gadget diagrams, and other substitute identifiers with solid match rates like IPV6 that could be utilized at scale for advertising viability.

Over the long haul, however, regardless of the opt-in rates in a post-IDFA world, we would prescribe publishers consider boosting users to advance first gathering information as a best practice and keep on instructing application users with the further extent of straightforwardness.

How will Apple send Postbacks from the app client to advertising networks that drive app installs?

  • Apple will use the SKAdNetwork API to receive metadata from ad clicks and to send postbacks from the app client to advertising networks that drive app installs. As of iOS 14, new parameters will be added to SKAdNetwork that provide information around the source publisher, and a conversion event;
  • The postbacks to ad networks can include ad campaign IDs, but only 100 values (labels 1-100) per ad network are available to be mapped;
  • The postbacks to ad networks can also include up to 64 conversion event IDs via a 6-bit conversion value;
  • The postbacks to ad networks will also include a “Redownloaded” flag that indicates whether the app is being downloaded by a user for the first time or not;
  • Postbacks will be sent based on a sequence of timers (the logic is somewhat complicated — more information on this below) and will include just one conversion event per attributed install. This means that advertisers won’t get absolute counts of events but rather counts of highest value events that users complete within the conversion measurement period;
  • IDFV, or ID For Vendors, will continue to be made available for publishers per device for all of their apps. What this means is that a publisher will have a unique device identifier available to it across its apps on any given single device. That is, if a user has installed three of my apps on her iPhone, I will have access to a unique IDFV for that user that is the same as accessed from all three of my apps.


What is SKAdNetwork? 

A class that validates advertiser-driven app installations.



class SKAdNetwork : NSObject


The ad network API helps advertisers measure the success of ad campaigns while maintaining user privacy. The API involves three participants:

  • Ad networks that sign ads and receive install notifications when ads result in conversions
  • Source apps that display ads provided by the ad networks
  • Advertised apps that appear in the signed ads

Ad networks must register with Apple, and developers must configure their apps to work with ad networks. For more information see Registering an Ad Network.

The following diagram describes the path of an install validation. App A is the source app that displays an ad. App B is the advertised app that the user installs.

When a user taps an ad, advertisers display an App Store product screen with signed parameters that identify the ad campaign. If a user installs and opens an app, the device sends an install validation postback to the ad network. The Apple-signed notification includes the campaign ID but doesn’t include user- or device-specific data. The postback may include a conversion value and the source app’s ID if Apple determines that providing the values meets Apple’s privacy threshold.

The responsibilities of each participant when using the ad network APIs are as follows.

The ad network’s responsibilities are to:

The source app’s responsibilities are to:

The advertised app’s responsibilities are to:

The device automatically sends the install validation postback when a timer for updating conversion values expires.


When you call API’s provided by SKAdNetwork from an app clip’s code, these APIs have no effect, return empty strings, or return values that indicate unavailability. For more information, see Choosing the Right Functionality for Your App Clip.


 Attribution in iOS14

That brings us to the last piece of the puzzle – attribution. Attribution is a double-sided problem since IDFA as a signal is required from publishers (impression and click) and advertisers (when an app is open and events within the app) for install measurements. Therefore, the opt-in rates will determine the success of user-level app attribution.  

As we understand today, Apple is trying to enforce a privacy-safe install attribution mechanism with SKAdNetwork. While it works for all users and does not require an opt-in, the granularity of attribution is limited.  

Alternatively, advertisers can also choose to deploy attribution fingerprinting models provided by mobile measurement platforms (MMPs) instead of using the SKAdNetwork, in addition to using their services for operational tasks including aggregating install receipts and reporting. However, in case advertisers choose to move away from MMPs and prefer the more deterministic, last-click attribution via Apple SKADNetwork, then MBS Info Solution will work with our DSP partners to ensure that the attribution is seamless. This includes helping DSPs distribute the ‘registered Ad Network ID’ to our publishers, enriching the RTB stream with new SkAdNetwork specific objects, all relevant documentation, and any other details to enable postbacks so that the optimization challenges are unblocked.

Apple is focusing more on privacy. Since the new commercial, they have launched is all about Privacy. Have a look :

Privacy. That’s iPhone. – Over Sharing


“Some things shouldn’t be shared. That’s why iPhone is designed to help give you control over your information and protect your privacy.” slogan said in the company official advertisement clearly shows that Apple is trying to enforce a privacy-safe environment for its users.

Apple won’t force developers to let users opt-out of tracking until next year


At its global developer conference in June, Apple said its forthcoming iOS 14 updates would allow users to opt-out of in-app ad tracking, a privacy feature that quickly drew ire from advertising giants over fears that it would make it harder to deliver targeted ads to users.

But now Apple is delaying enforcing the feature until “early next year,” the company confirmed.

Expected out later this year, iOS 14 will contain a new prompt that asks users whether they would like to opt in to this kind of targeted ad tracking. Developers will be able to integrate this prompt into their apps as soon as iOS 14 is released, but they will not be required to, as Apple indicated they would earlier.

In a statement, Apple said:

We believe technology should protect users’ fundamental right to privacy, and that means giving users tools to understand which apps and websites may be sharing their data with other companies for advertising or advertising measurement purposes, as well as the tools to revoke permission for this tracking. When enabled, a system prompt will give users the ability to allow or reject that tracking on an app-by-app basis. We want to give developers the time they need to make the necessary changes, and as a result, the requirement to use this tracking permission will go into effect early next year.

Although Apple cites the necessity of giving developers time, major advertising companies like Facebook have warned that the change could severely impact their operations. “Apple’s updates may render Audience Network so ineffective on iOS 14 that it may not make sense to offer it on iOS 14,” the company said in a statement last week.
