The only constant in life is change, and several months after
the IDFA deprecation,
another news from Apple keeps the app marketing world in suspense.
A major software update is expected to be officially announced after June 7, but
thanks to
Bloomberg sources in Apple,
we already know what to prepare for.
In this blog post, we’ll fill you in on the current state of iOS 14.5 app
marketing past IDFA deprecation.
We’ll disclose how iOS 15 and iPadOS 15 will be different in terms of
notifications and user privacy.
Finally, we’ll show you the strategies to make up for acquisition and
attribution deficiencies.
Together with Adjust, we have prepared the answers to the most common questions
our clients asked us:
What exactly is IDFA and how important is it actually?
How will it affect your marketing campaigns?
Are there any alternatives to use instead of IDFA?
How to reduce the negative effect of IDFA deprecation
What changes to expect in iOS 15
Conclusion: how to act now
What exactly is IDFA and how important is it actually?
IDFA — Identifier for Advertisers — is a unique number that Apple
assigns to each device for tracking and attribution purposes. It helps the whole
mobile marketing world analyze their campaigns’ efficiency and work with user
data.
Besides the metrics calculation, IDFA is also responsible for ad spend
attribution and visualization of each user’s behavior from the first ad click to
post-install and purchase actions.

This data helps app marketers make better-informed data-driven decisions and
improve customer personalization, segmentation, acquisition, and engagement.
If IDFA is so important, why was there almost no talk about it before 2020, you
may ask.
Well, the fact is that on earlier version of iOS, IDFA was active on all Apple
accounts by default. Since iOS 10, users could only Limit Ad Tracking (LAT) at
the device level within their app Settings.
What’s is different in iOS 14.5 in terms of IDFA?
Starting with
iOS 14.5, released recently,
IDFA is hidden in the depth of settings by default. Apps can get access to
IDFA only if users opt in via a pop-up at the app open. Yes, they will have to
do it each time with each new app.

Do you think customers will choose to opt in or not more often?
Before the iOS privacy update, 15% of users would choose to limit IDFA
tracking. Now, a more
recent testhas
15% of consumers to allow app tracking. In the most
optimistic case,
38.5% of users may opt in for IDFA.
How will it affect your marketing campaigns?
As a marketer, you should know that just one additional pop-up can easily break
the sales flow that you worked so hard on.
Besides the acquisition funnel, asking users to share their IDFA might have a
crucial impact on the following 5 major areas:
1. Attribution
It’s mainly attribution that helps marketers understand user reactions to a
particular campaign, consolidate relevant real-time data and build reports.
As you may have already guessed, the need for IDFA consent will make it
significantly harder to determine what gets credit for the final conversion.
Furthermore, this will cause difficulties in:
- showing relevant ads to the audience;
- creating seamless personalized experiences for customers with the use of
relevant deep-linking;
- justifying ad spending and maintaining the revenue level.
2. Retargeting
Hypothetically, you can still retarget users based on non-IDFA identifiers:
emails or phone numbers, for example. But to do so, you will have to receive the
user’s permission through the
AppTrackingTransparency framework.
How many users will be ready to share this information with you at the very
beginning?

3. Identity management
In the world of digital advertising, data became the new oil a long time ago.
Advertisers used to send device IDs and post-install events from attribution
platforms to DSPs. They would store all the valuable information about each
device for further monetization. Creating device graphs and audience profiles
using IDFAs would generate a fortune for DSPs. Without IDFA, it will be a
difficult time for them.
4. Fingerprinting
Fingerprinting is a technique used to identify people who have interacted with
an advertisement by using publicly available characteristics of a particular
device. This can be a user’s IP address, location, device type, local network
data, and any other accessible data.
Fingerprinting was always a lifesaver in cases when IDFA wasn’t supported by
advertising networks.
Some publishers hoped to achieve at least 70% of fingerprinting accuracy on iOS
and soften the negative impact of IDFA. But it doesn’t seem to be a good plan
after Apple
claimed
fingerprinting will also require user permission.
5. User onboarding
Now all marketers are trying to come up with creative solutions on how to opt-in
users to get the needed data from them.
Some companies are considering not allowing customers to use the app until they
sign up via their social media account or fill out their profiles.
Others are scratching their heads over how to show their apps’ extra value to
convince users to provide the necessary information.
Well, there are actually better ways to make
user onboarding
more effective in this sense. Create a welcome flow that will be:
- automated (based on user behavior);
- cross-channel
(in-apps +
push notifications + emails);
- and personalized (i.e. relevant to each particular customer).
How do you create such a powerful experience? With
Pushwoosh Customer Journey Builder
you’ll be able to onboard users effectively, reaching them at the right time
with the right content and, most importantly, via the channels that work best.
There is a dedicated Welcome Series template — take inspiration from it to build
your unique onboarding flow.

Are there any alternatives to use instead of IDFA?
Actually, there are some. Mobile attribution companies have polished their
solutions to attribute events without the use of IDFA. Adjust, for example,
offers
three different methods
to their partners:
- Opt-in deterministic attribution using the AppTrackingTransparency framework;
- Probabilistic measurement fueled by several non-deterministic signals;
- SKAdNetwork as an additional set of data.
Another strategy is to pay closer attention to the
customer engagement
experience.
Cross-channel marketing platforms like Pushwoosh don’t use IDFA to send and
track push notifications or in-apps. The tools follow the
behavioral marketing
concept and build
event-based
personalized flows that don’t require any additional actions from users.
If you are a current user of Pushwoosh, we recommend you make sure your SDK is
updated to
the latest version.

How to reduce the negative effect of IDFA deprecation
1. Review your use of IDFA
It’s important to complete a full internal review of how you are currently using
IDFA. This will give you a solid understanding of where and how you rely on it
in your marketing, and how your efforts can lose efficiency without it.
Do you work with any mobile measurement platforms or networks whose
SDKs use IDFA? How do your CRM platforms
and other software services rely on it? Make sure to also talk to each of your
SDK providers to hear about their solution for IDFA requests on iOS 14.15.
NOTE: Pushwoosh SDK doesn’t use IDFA, so your audience and campaigns are
safe with us. Just ensure you’re using
the latest version
of Pushwoosh SDK
2. Customize your opt-in request
Getting user consent for the IDFA use should be your next priority.
If users keep opting in, you’ll be able to keep your activity on the pre-iOS 14
level. Besides, high opt-in rates can become your competitive advantage.
Obviously, this means a lot of work to develop the consent mechanics and
message, and it will likely take some trial and error to get high opt-in rates.
So we recommend you start running your tests now.
As of today, we know that some parts of an opt-in message (shown below) can be
customized. However, in the future, Apple can potentially create even more
opportunities for fine-tuning your request.

NOTE: You can also experiment with when exactly to trigger the request
delivery, as showing it right from the app start might not be the best idea.
3. Work with user retention
It’s been common knowledge that acquiring a new customer can cost five times
more than retaining an existing one. Now the situation has become even more
complicated because targeting your potential customers is not that easy anymore.
Some apps have already seen their cost per install triple — only two weeks
after the iOS 14.5 release.
Now is the great time to diversify your
re-engagement
options — whether through
push notifications,
emails,
etc. It is also the right moment to elaborate on the right mechanics to collect
user permission for these options.
4. Analyze user segments within your engagement flows
Your user engagement campaigns may become a source of data no less powerful than
IDFA.
Look into your event-triggered communication workflows: at each step, you can
Set Tags
and track your users’ reaction to your messages, as well as their in-app
actions.
You can create user segments as precise and granular as you need to get a full
understanding of their journey and keep customers engaged with the most relevant
communications.

5. Re-evaluate your BI stack
The IDFA privacy measures will surely impact how your BI stack works.
Don’t forget to look into what different data sets are stitched together for
your analytics and think about how you can continue to stitch together this
internal data after the iOS 14.5 release.
Some good options include focusing on IDFV, ADID (your MMP unique
identifier), and UserID (your internal ID if it’s being used across your
entire mobile marketing stack).
Apps working without the IDFA will still be able to place contextual ads, but
they will no longer place personalized ones. It can cause revenue drops by
various percentages, as personalized ads are worth much more. It’s better to
prepare for what should happen as a reaction to these changes.
6. Discuss your planned measures with partners
Talk to your marketing partners and align the use of IDFA in their targeting
strategy. A reliable marketing partner should leave with a clear understanding
of how they are preparing for the change, specifically when it comes to
lookalike audiences, re-targeting, re-engagement, white- and blacklisting, and
seed audiences. The same can be applied to monetization networks.
What changes to expect in iOS 15
Apple is expected to present another batch of changes to the notifications
policy and privacy guidelines at its upcoming Worldwide Developers Conference
beginning June 7.
The new iOS 15 and iPadOS 15 will be officially released in the fall — until
then, developers will have to get their apps ready for the updates:
Notification preferences will change in response to user statuses
Reportedly, users will get to change their current status such as “driving”,
“sleeping”, “working”, etc. They will select it from one of the categories in a
new menu or create their custom option.
Depending on the chosen status, a phone will make a sound when it receives a
notification or stay silent.
This will certainly affect the way users interact with pushes. The question is,
how.
Will many pushes stay undelivered? Will users be more likely to click on
notifications because they will receive them at a more convenient time? Or will
users prefer to stay in the silent mode and ignore pushes altogether?
A new menu will let users know which apps are silently collecting their data.
Supposedly, this will be possible with the same data used for “privacy labels”
that Apple introduced last December.
The quality of attribution may drop even lower than it has with the iOS 14.5
changes. This is when a strong customer engagement strategy with a focus on user
retention will be needed.
Conclusion
Numerically, iOS accounts have fewer app installs than Android, but iOS users
are
more valuable and spend about 2.5 times more money.
That’s why ignoring the upcoming changes is a mistake many businesses can’t
afford.
To minimize the negative effect of IDFA deprecation, it’s crucial to start
acting now. Pushwoosh is always ready to share insights and offer ways for your
apps to adapt to the changes successfully.
