 1. ** What is Limit Ad Tracking (LAT) in Apple’s iOS operating system?**

Have you ever wondered what Limit Ad Tracking (LAT) is on Apple’s iOS devices and
how it affects advertisers? Before getting into that, we need to start from scratch.
Advertising networks like Apple or Facebook keep track of a considerable amount 
of information about you, including your location, your age, your gender and which
product and apps you own. This information is stored and then used to show you relevant
ads based on the things you like. The underlying reason is maximizing value for 
the ad networks. The higher your interest in the ad, the higher the likelihood you
will click on it, which in turn will generate revenue for the ad networks. Therefore,
in order to serve ads that are relevant to you, these networks collect data to build
advertising audiences. The audience to which you are assigned determines which ads
you will receive. This will mainly depend on your interests as well as your recent
activities (meaning that if you showed interest in a product, it is highly likely
that ads will be customized according to your taste). This practice is called targeted
advertising.

ads-min.png)

But then what is LAT and how is it related to targeted advertising? An expert in
the sector, the Mobile Measurement Partner Adjust, can come to our rescue in this
case:_ “Limit ad tracking (LAT) is a feature allowing users to opt-out of having
an ID for Advertisers (IDFA). With this setting enabled, the user’s IDFA appears
blank when tracked. This means they won’t see specific ads targeted at them because,
as far as networks see, the device has no identity.”_ In other words, when activating
the LAT option you are ultimately stating that you do not want to be tracked and
you do not want to belong to a certain audience.

 1. ** An overview of the LAT ON development over time**

The LAT ON setting has been gaining popularity after scandals such as the [Facebook–Cambridge Analytica data scandal](https://en.wikipedia.org/wiki/Facebook%E2%80%93Cambridge_Analytica_data_scandal),
which raised public awareness on the importance of data protection and privacy. 
The news was revealed On March 17, 2018 by [the Guardian](https://www.theguardian.com/news/2018/mar/17/cambridge-analytica-facebook-influence-us-election)
and [the New York Times](https://www.nytimes.com/2018/03/17/us/politics/cambridge-analytica-trump-campaign.html).
To show the real impact generated by LAT ON on Apple Search Ads advertising, [SearchAdsHQ](https://searchadshq.com/)
kindly provided Phiture with data regarding LAT ON traffic. Their data source is
composed of 7 million aggregated downloads from their clients.

As you can see in the graph below, after March 2018 there is a steady rise of LAT
ON users which increased from 17% up to almost 34% in January 2019 in the US. That
is a significant expansion, clearly showing the development of privacy concerns 
over time. While the LAT ON share seems to have stabilized at around 34%, external
factors, like another privacy scandal, might cause another increase in LAT ON over
time.

As is the case in the US, Australia, Canada, Germany, France, the UK and Mexico 
are also witnessing the rise of LAT ON. As you can see from the chart below, all
the selected countries have experienced a LAT ON share increase over the last 2 
years. Some of these such as the UK, Canada and Mexico seem to have been directly
impacted from the Cambridge Analytica scandal in March 2018. Other countries do 
not seem to have been directly affected by that event but they started having a 
visible increase after September 2018, once Facebook claimed that “hackers exploited
a series of bugs to access the Facebook profiles of [some 30 million accounts](https://www.wired.com/story/how-facebook-hackers-compromised-30-million-accounts/)”
as [Wired](https://www.wired.com/story/how-facebook-hackers-compromised-30-million-accounts/?verso=true)
reports. In the image below you can track the LAT ON share development over time
in Australia, Canada, Germany, France, the UK and Mexico.

So, how do users activate the LAT ON feature in your Apple device? In a section 
called “Advertising” if you go to “Settings” and “Privacy Options”, you can activate
Limit Ad Tracking by toggling on the option (see picture below).

**III. Apple Search Ads (ASA) advertising and LAT targeting pros and cons**

If you are an advertiser utilizing Apple Search Ads, LAT ON traffic might be very
interesting to target, but it can also bring a few headaches if you are not entirely
considering all of the implications.

In performance marketing, advertisers try to optimize their ad spend based on the
performance of their campaigns. They track what they spend on the campaign, attribute
the acquired user to the campaign, and measure what the user does and how they monetize
in the app. This way the advertiser can calculate a Return-on-Ad-Spend (ROAS) on
a campaign and decide whether to invest more into that campaign or not.

When acquiring a LAT ON user from a campaign, advertisers won’t be able to see with
the Apple Attribution API or their Mobile Measurement Partner (MMP) where that user
came from (due to the privacy protection enabled by Apple). Therefore, this user
will be added into the bucket of organic unclassified users and the revenue he/she
generates won’t be attributed to the success of the campaign. You will still be 
able to see the download in Apple Search Ads, but for modern mobile performance 
marketers, downloads or cost-per-install (CPI) are not the core KPIs they want to
optimize for. This can be an issue if you are specifically trying to: 1) measure
the percentage of ROAS these users generate and/or 2) to observe if these users 
convert into a signup or subscription.

So how do you exclude LAT ON users from showing up in your campaigns?

There is no hint in Apple Search Ads’ interface on how to do it, but basically by
enforcing any kind of Demographic targeting you will not reach LAT On traffic. One
interesting finding we have experienced at Phiture is that when having location 
targeting on Berlin, but also demographic targeting set to “all” (meaning LAT ON
would be switched on), LAT ON would prevail on the location setting.

In sum, in order to include this traffic, you have to set in each of your ad groups’
settings “all” when setting _age range_ (see picture below). This would allow you
to target LAT ON as well as LAT OFF inventory.

![audience](https://phiture.com/wp-content/uploads/2019/08/audience-min.png)

According to the reasoning above you may have inadvertently avoided this LAT ON 
traffic. Not targeting LAT can be a restricting decision which will lower your ASA
potential. Apple claims that on average the LAT traffic is around 20% of the total.
We’ve found with the data provided by SearchAdsHQ that the number of LAT ON downloads
hovers around 25% of the total, globally. As a consequence, that percentage represents
a high number of users who, if not targeted, might fall into competitors’ hands.
The second reason to include this portion of traffic, is that it can often be somewhat
cheaper as other advertisers are not entering the LAT ON auctions because they want
to be able to calculate an exact ROAS.

Clearly, the percentage of LAT users varies per industry. In the lowest represented
industry (Entertainment) we are talking about 11% of LAT ON traffic. The most represented
industry (Social Networking) reaches a 30% share of LAT ON, per SearchAdsHQ data.

 1. ** How to extrapolate LAT ON metrics from LAT OFF data**

If you still want to target LAT ON traffic and want to estimate what value those
users add, you can extrapolate the likelihood of these users to complete a given
event down your app’s funnel. [Thomas Petit coined this concept](https://www.appsflyer.com/resources/mama-boards/apple-search-ads-best-practices/)
first in a whiteboard session with Appsflyer, and it’s now been adopted widely in
the industry. Let’s move to an example: let’s say we want to make an educated guess
as to how many LAT users completed the event “subscription”, which will be our “
goal” event.

As we do know how many subscriptions (i.e. Goals) the attributed bucket (=LAT Off)
created, and what the share of LAT ON Downloads is (as Apple gives us the split 
of this traffic), we can guess the number of subscriptions that were created by 
extrapolating the LAT Off Goals from the LAT ON available data. In other words, 
we take the LAT off goals and estimate the LAT ON goals by taking the percentage
of goal completion in LAT off as a benchmark to calculate the LAT ON goals. The 
formula we utilize to estimate the total goals from our accounts is the following
one: Total Goals (extrapolated)=_LAT Off Goals/LAT Off Downloads Share._

From the above formula you could also be able to calculate an estimated Cost Per
Goal (CPG) and similarly also an estimated Cost Per Install (CPI) and ROAS which
can give you more precise metrics when making analyses. See below how we do these
extrapolations at Phiture.

![Goals vs. Total Goals ](https://phiture.com/wp-content/uploads/2019/08/Goals-vs.-
Total-Goals-min.png)

While you are able to do this on the campaign, ad group and keyword level, we have
found the granular data on keyword level to be less statistical significant. Of 
course this is just an estimation and does not reflect 100% the true data coming
in from LAT ON: can you assume that this traffic would convert just as well as their
LAT Off counterpart? Most likely, there will not be a massive difference between
how privacy sensitive users looking for “music app” convert into a subscription 
versus their less privacy sensitive counterparts. However, for some verticals like
VPN software the opposite might be true, and it’s always good to fact-check your
assumptions over the whole account by doing a before-after comparison when switching
on LAT ON. You can look at your organic bucket and see if your goals in that bucket
grew at the same pace as your LAT ON downloads came in. If your organic user base
is too large, try singling out one country in which you don’t get a lot of organic
downloads.

To summarize, LAT ON traffic is an asset which can be extremely valuable for your
Apple Search Ads advertising. This, coupled with a [systematic campaign structure](https://asostack.com/how-to-set-up-a-systematic-apple-search-ads-campaign-structure-with-5-campaign-types-64a0fa0b21d4),
can certainly allow you to succeed with Apple Search Ads and get the most out of
your Apple Search Ads account. Given the fact that LAT ON potential corresponds 
to around 25% of the total global ASA traffic, you would be able to target a significant
number of users and expand your advertising efforts. Moreover, knowing what LAT 
is as well as being able to estimate its outcomes can improve your decision making
and reporting. As you would be adding goals by estimating the missing data, you 
would also improve your performance, which would have been underestimated before
the calculations!
