Unless you are deeply engaged in digital marketing or analytics it is unlikely that you would have heard about ITP 2.1 The acronym ITP stands for Intelligent Tracking Prevention and it is built into the latest versions Apple’s Safari browser and the latest update has big consequences to your tracking and marketing.
This technology actively prevents tools such as Google Analytics from tracking users for periods longer than 7 days. In essence, your users will be forgotten about if they don’t return to your website within 7 days from their last visit.
So, what does this actually mean?
Well, if your company is trying to send remarketing campaigns or to track how users engage with your brand over time, then you have an upper limit of 7 days for all your Mac and iOS users who use the Safari browser.
How big an impact is this likely to be?
We sampled 40 of our clients, we found that on average, 35% of their users use the Safari browser, with the impact being even higher on mobile and tablet devices.
On mobile devices, there was an average of 56% of users who use the Safari browser.
On tablet devices, these numbers grow larger, with an average of 70% of users using Safari.
The bit impact of ITP is on returning users who have not returned to the site for more than 7 days. Our study reflects that the impact ranges between 1% up to 12% depending on the client.
If you are running remarketing campaigns, then this is likely to be a big impact on the effectiveness of this marketing in reaching these users.
What will be the effect?
You will see a rise in new users coming from Safari users and a decrease in the days since the last session and sessions per user.
Is it just Google Analytics that is impacted?
No, most web analytics and tracking technologies that are used are impacted by this change.
Is there anything that I can do?
Yes there are techniques that can fix this however each of them requires significant technical work.
Simo Ahava has written a very detailed blog post on the topic that covers the options that are available. https://www.simoahava.com/analytics/itp-2-1-and-web-analytics/
Why has Apple done this?
Apple has repeatedly demonstrated its staunch position on privacy with a key example being its refusal to comply with FBI directives to circumvent the encryption in its iPhone during 2015 and 20161. Later Tim Cook the CEO of Apple in his speech in 2018 to the European Union Privacy commission stated Apple’s position strongly and clearly with “Our own information, from the every day to the deeply personal, is being weaponized against us with military efficiency.” and later “At Apple, respect for privacy—and a healthy suspicion of authority—have always been in our bloodstream.”2
In its recent blog post on ITP 2.1 Apple has made the following statement “Apple believes that privacy is a fundamental human right and that users should not be tracked across the web without their knowledge or their consent.”3
Whilst a more cynical view could equally hold that Apple is directly seeking to compete for public perception to be the good guy in the battle for privacy against its competitors such as Google. It must not be forgotten that Google has products that directly compete with Apple’s.
One way or another Apple’s position indicates that it is likely that this will be an increasing problem going forward.
Firefox appears to be following Apple’s lead and now appears set to implement something similar in the near future.4

A common question that businesses ask themselves is “Which of my customers are the most valuable?”.
While this is a simple question, there are ways of answering this which can prove to be quite complicated. For example, how does the business define “valuable”? This could be customers who spend the most in total, or customers who have a large number of transactions. Alongside this there are other considerations, such as how recent the last purchase was, or the average basket size.
Luckily, we can use the Recency, Frequency and Monetary framework (or, RFM) to help us identify high value customers.
What is RFM?
As the name suggests, RFM takes into account 3 factors for determining the value of different customers:
When did the customer last buy an item? Can we identify if a customer is “active” or has “lapsed”?
How many times has a customer made a purchase? Can we identify customers who make many purchases, or few purchases?
How much in total has each customer spent?
Using these three dimensions can help identify different segments of the user base which would respond to different marketing messages and promotions.
Analysis using PowerBI
PowerBI is a business analytics service that delivers insights by transforming data into stunning visuals. We have loaded example customer data into PowerBI to create an interactive visualisation for you to explore the RFM framework.
After loading sample customer data into the PowerBI platform, we can look at the demographic profile of those customers who score highly in the Frequency and Monetary dimensions.
The demographic data can help marketers keep their messaging relevant, should they choose to reach out to the different segments.
A particularly interesting group of customers are those who have a high Monetary score but a low Recency score. In other words, they are customers who have spent a lot of money but have not done so in a while. The business may want to consider strategies to re-engage those customers as doing so would likely prove to be very profitable.
In another tab of the dashboard we can see the (fabricated) names and email addresses of the customers in a table. This can be filtered and exported to create custom lists for marketing purposes.
The screenshot below shows those customers who:
- Are married
- Belong to a 2 adults, no kids household
- Have previously spent a lot with the business
- Transacted recently (active customer)
With the flexibility in filtering that PowerBI offers, it is a great platform for ad hoc customer segmentation for frontline marketers and stakeholders. There is also the ability to export the data once filtered, so users are really empowered to do what they wish with the data.

Nothing causes senior management or a business owner to distrust the numbers faster than errors in the data. Once that trust is gone it’s very difficult to win back.
Whilst it is important that any user of Google Analytics Enhanced E-commerce understands that the transactions that are recorded will not match your accounting system exactly, they should be very close. Typically we aim for an error rate of less that 5% but have seen differences up to 10% on a healthy website with no tracking issues.
Some of the key errors that might be influencing your data are listed below:
Whilst a small amount of missing transactions is virtually unavoidable sometimes errors can creep in.
Common issues that cause this are:
- Incomplete data being sent to Google Analytics. The user exiting the browser if the confirmation page takes too long to load is a common cause.
- The customer is not always sent to the confirmation page that sends the data to Google Analytics. Paypal and other external payment gateways can sometimes cause this if the customer doesn’t fully complete the process and return to the thank you page.
Too Many Transactions
If you see that the total count of transactions is higher than expected it is likely that some customers can reload the confirmation page that sends the data to Google Analytics and cause that transaction to be double counted.
This can happen if you send a confirmation email to the customer that encourages to return to their order details and your system reloads the Google Analytics code when the user visits that page. It can also happen if the customer reloads their confirmation page.
The solution to this is to only send the data to Google Analytics the first time. This may require modifications to your shopping cart as many will allow for the full transaction details to be reloaded when the confirmation page is refreshed.
To check if your data includes any duplicate transactions, click on the link below to view a custom Google Analytics report and select your normal Google Analytics view when prompted. The number of transactions per transaction ID should only be “1”.
Duplicate Transaction Report
Not Tracking Refunds
Whilst it is a little harder to implement if your store receives a large number of refunds this can significantly bias the data. Google Analytics can reverse transactions by sending a refund event. Removing these sales is important to ensure that you accurately measure the results of your marketing campaigns.
Incorrect Sales Attribution
This is the number one issue that we are brought in to solve time and time again.
There are two main causes of this:
The first occurs when your payment gateway is on a different domain and the final confirmation page is on that domain. The symptom that you will see is that all sales are attributed to that domain. The reason for this is that the customer’s is tracked as a different user on the payment gateway site.
The solution to this is to implement cross domain tracking so that the user can be tracked consistently across both domains.
Tip: Use Google Tag Manager. It makes solving this problem much, much easier than doing this using straight Google Analytics code.
The second occurs when the customer is taken to a different payment gateway and then is redirected back to your own store to see the confirmation page. In this case you might see your own site, Paypal or some other payment gateway as the source of the sales from your site.
The solution to this is to add all of your sites and the payment gateway domains to the list of ignored referrers in your Google Analytics settings.
There are many other ways in which you can receive unexpected data. If you need help in solving these please contact us for support.

I really like the word phantasmagorical but I rarely have a chance to use it.
It’s by no means a common word – so a simple definition might be useful:
Now with that in context, it’s fair to say that Donald Trump’s election has surprised more than a few, and that the use of the word phantasmagorical is highly justified. From many a perspective, it was inconceivable that someone with his rhetoric or political inexperience would be elected leader of the USA.
From the start, Nate Silver’s FiveThirtyEight website has provided great insight. It’s had a solid history of good predictions and is seen as a reliable source of information, condensing large numbers of variables into a predictive state. During the election I also chose to revisit Nassim Taleb’s book Antifragile as a companion to FiveThirtyEight. Ever since reading his first two books, Fooled By Randomness and The Black Swan several years ago I have been fascinated with statistics, volatility and randomness in general.
A key message I took from Taleb’s books was that prediction of rare events is not possible. The world is a chaotic and complex system with many variables where interactions lead to unexpected and unpredictable outcomes. Whilst we can measure many things using solid historical data, it is the unseen variables and their even greater unknown interaction (both seen and unseen) that can quickly send predictions through the floor…..as we saw.
As a long term practitioner of analysis using statistical tools and approaches I have long come to respect that models are just models – they are not the world itself. In the oft quoted words of George P. Box and Norman R. Draper (1987) “Essentially, all models are wrong, but some are useful”. Equally I have come to understand that to correctly use statistical tools you absolutely must deeply understand how they work and what their limitations are. (Like whether the media is involved?)… side thought.
There are many cases where forecasts and predictions based on data and analytics has worked, but we must always be mindful when using these tools that we are making predictions based on past observations. There have been 58 presidential elections in the entire history of the USA. As such, any model trained on predicting an event which only occurs every 4 years with 58 outcomes across 227 years is likely to get it wildly wrong from time to time. To give an analogy, all swans are white until you see a black one.
What I think we have seen with the US election results, and Brexit too, are black swan events. They’re emerging from many factors which are leading towards some large changes in the future. It seems very likely to me that the forecasts which were being made during the election campaign were inaccurate simply because nothing like this had been observed before.
Statistics and predictive analytics are great tools, but I also strongly encourage you to examine and understand the work of Nassim Taleb
, Daniel Kahneman
, Amos Tversky
, Philip Tetlock
and many others who work in the areas of of understanding human behaviour, the limitations of our minds and complexity science.They may not help you to predict your outcomes, but adding their approaches to your toolkit of techniques will help you to better understand the world, appreciate the limitations of data and analytics, and make you a much better marketer and analyst.
