Piwik Pro: To Meta or not to Meta

Pros and Cons of Meta Sites

Our reporting hamster, a Piwik Pro client with multiple sites, has to answer a difficult question: Do we go with a Meta Site setup or not? Meta Sites are a powerful feature to aggregate multiple sites in one (Analytics) or centralize element management (Tag Manager). But there are trade-offs (e.g., deduplication challenges in Analytics or transparency in Tag Manager) which can be showstoppers or just minor footnotes, depending on your use case. This post summarizes the pros and cons for Analytics and Tag Manager and offers a compromise.

"Paid Search" & "Organic Search" are useless Marketing Channels

Why Search Channels need to be split up to mean anything at all

Back to basics: What is a sensible Marketing Channel (aka “Channel Group”) setup in your Web Analytics tool? A frequent mistake is treating Paid Search traffic as one single Channel. Why that might be in your agency’s best interest. And why the same applies for Organic Search.

Best Practices for Adobe Analytics Alerts

Your Data Quality Frameworks starts here

My daily routine could not be more boring: It starts with checking Alerts. Some of the most important messages are the ones coming from Adobe Analytics. But how can you ensure Alerts stay relevant? How do you create Alerts in bulk efficiently? How do you avoid Alert e-mail floods? Should you use a lot of Hourly Alerts? And what's the best significance threshold?

This year has been my ten-year anniversary with Adobe Analytics. For all those years, there was always one thing I wanted. But I was always too lazy to get it done. It was something rather primitive.

Adobe Customer Journey Analytics: My Top 10 Wishes and Highlights

A look at substitutes for Data Warehouse, Data Feeds, Alerts, User Stitching, Analytics 4 Target, and more

Have you delved into Customer Journey Analytics (CJA) yet? I finally did this year. And I discovered plenty to admire — but also some obstacles that Adobe should tackle before I’d migrate clients from Adobe Analytics (AA) to CJA. Curious about the highlights and challenges? Here’s my personal rundown.

When Bots start doing Human Work, but Adobe Analytics still treats them like Bots…

A couple of months ago, Adobe migrated the Bot Reports to the Analysis Workspace interface. Maybe they also updated some of the Bot Filtering logic since then, because the number of Bots identified seems higher than in the past, maybe it is just another real Bot rush.

Firestore Tips 3-5: Properties any Document Needs & Handling Concurrent Document Updates

How to securely update keys and increment numbers “atomically”

Imagine two people writing a message on the same piece of paper, at the same time, without seeing each other’s message until after they are done. The outcome will likely be an illegible mix. Similar things can happen in Firestore if you don’t handle concurrent document updates properly. The second episode of my series with Firestore tips helps you with that.

Firestore Tips #1 & #2: How to Play God in Firestore, and Firestore vs. SQL

Plus: Why going against the alphabet makes queries easier

Long before Firestore made it into the toolkit of Google Tag Manager’s Server-Side offering, it was a powerful document database. Working with Firestore for some years now, I want to share simple tips that may help you avoid the same mistakes I made. First though, I will compare Firestore with classical SQL-style databases.

Piwik Pro’s World of Privacy Settings

From “Anonymous Tracking Mode” to Session ID (now “Session Hash”), and: Can you actually track with a Session Cookie only?

The original aim: Track users with only one Session Cookie to comply with certain GDPR interpretations. That started an intriguing journey through the various privacy mechanisms of Piwik Pro. What is “anonymous” about the “Anonymous Tracking Mode”? What is the difference between the Session ID and the Session Cookie? And does Piwik Pro do fingerprinting?

Leveraging your TMS & Adobe Analytics to Monitor Adobe Target, ECID & other Services

When you need to wait, you better know for how long

What do you do when your AB testing tool starts delivering experiments a second later? Nothing. Because you likely won’t notice. Why you need to monitor the services your web analytics depends on. Real examples!

In part I, I look at examples why it is important to measure the performance of services your Analytics tracking depends on.
In part II, I show how to implement that. Do you have my must-have performance metric in your tracking setup?

Comparing Adobe Analytics, Google Analytics, and Piwik Pro by Emotional State During Usage

Let’s talk about Feelings

Who came up with the nonsense that we should decide based on data, not emotions?! Not me! I am fully emotional in all my decisions, and the same holds true for this tool comparison: The only criterion is my emotional state while using GA4, Adobe Analytics, and Piwik Pro — three solutions that couldn’t be more distinct when it comes to feelings…

Making Large Segments Small Again

Losing Weight — A Pruning Diet for your Overweight Adobe Analytics Segments

Every Analytics account has them: Giant, important segments (e.g. for Bot Exclusion) that have become unmaintainable. They are a drag on performance, they cause mistrust in data, and nobody wants to touch them because they are so complex.
In part I, I investigate the maintenance burden of such segments, and how they grow into such unmaintainable Goliaths in the first place. We put this knowledge into practice in part II and get our hands dirty with lots of Python and the API, rebuilding the "Segment Pruner", a function of the Adobe Analytics Component Manager for Google Sheets, on our own computer. In the end, our winning smallest possible, non-data-changing segment alternative will get some fancy Capitalist prizes. ;)

Get Adobe Analytics Reports into Looker Studio (or Google Sheets)

Adobe Analytics has a great analysis interface. But getting reports out of Adobe Analytics into a dashboarding solution like Google Looker Studio or even a Google Sheet was so far impossible without some tech-heavy process in-between (or expensive).

From Google Analytics to Piwik Pro? A real Client Cases

And why Matomo didn’t make the cut

Part 1 tells about a client that was unhappy with the limitations of Google Analytics 4 and finally looked at other options and decided to test-drive Piwik Pro. But why not Matomo?
Part 2 answers questions: How did Piwik Pro fare in the POC? How easy was the implementation via GTM, how smooth the integrations with Google Ads, Search Console, and Looker Studio? What about the data quality? Where should Piwik Pro improve? And which tool did the client choose finally?

Analytics Tea Break #5: How to Replace the Sunsetting Hierarchy Variable in Adobe Analytics

An eVar, Classification Rule Builder, RegExp Extractions — and “Combo Hierarchies”

My great late grandfather often lamented that today’s youth has no more respect for hierarchies. Adobe Analytics has caught up to that trend and retires the good old “Hierarchy” variable. This post shows how you can migrate it to an eVar or prop. And if you have not done any content-hierarchy-level-focused analysis yet, I will set you up for that as well. Bonus: the powerful “Combo Hierarchy” dimensions.

Why the Death of Sessions is a Myth

We are not really in an “Age of User-Centric Analytics” yet — rather the Opposite

Analytics Tea Break #2: How to Increase your GA4 Conversions 20-Fold without Touching GTM

Why creating or modifying Events via the GA4 Admin section should only be last resort

Recently, I got to spend some time with some really nice Digital Analysts from one of those Google-only monolith agencies. At some point, we got to the topic of vendor tunnel blindness — when you are sticking to your current vendor, not looking left or right, as if there were no other options. While this phenomenon is strong in both the Google and the Adobe tunnel, the recent Google Analytics 4 tunnel blindness is particularly striking: Even though many are hating on GA4, relatively few seem to seriously consider other tools; most even treat the migration to GA4 like something prescribed by the laws of nature.

Analytics Tea Break #3: Harder than you Think — Opening Adobe Analytics Data Feed Files with Pandas

The Long Journey around the UnicodeDecodeError

Adobe Analytics Clickstream (Raw Data) Feeds can be highly useful, but getting started with them can turn out a bit cumbersome. Especially complex is the treatment of non-ASCII characters (äöüßéàê“” etc.). If you try to open a file that has such a character in the wrong spot with Python’s popular pandas library, you will get a breaking error. Luckily, there are (undocumented) workarounds.

Analytics Tea Break #1: Stop using Adobe Analytics linkTrackVars & linkTrackEvents

“Analytics Tea Break” shows little Digital Analytics tips & tricks. Reading them should take no longer than your average tea/coffee/cigarette break.

The classic Adobe Analytics implementation has some concepts that need some practice to get used to. Some of them can be discarded altogether and make your implementation a lot easier. My favorite: linkTrackVars and linkTrackEvents. I would bet that anybody who has done an AA implementation has had bugs because of them. Even though they are completely unnecessary!

Issues of Tracking QA Solutions, and what a better one could look like

Automated Client- and Server-Side QA of Data Collection

The futile (?) dream of many Digital Analytics/Tag Management/Data Collection specialists: a tracking implementation where every measurement point in any technical constellation is automatically validated against non-trivial, up-to-date rules and serves you errors on an actionable silver plate: Perfect, automated QA of data collection (aka “tracking”). There are good solutions, but they are limited, and they focus on the less relevant (part 1).
We show a solution that does (almost) all the things I want a data collection QA solution to do, and it does so without requiring licensing fees (apart from a couple of dollars monthly on Google Cloud Platform). We use Mocha & Chai for visual client-side ad-hoc data validation (part 2) and then take the whole thing server-side in a scalable way so every user becomes a data layer tester (part 3).

What a Customer Data Platform (CDP) Should Offer

From Real-Time Multi-ID User Stitching to Triggering Flexible Actions

The number of vendors claiming to offer a Customer Data Platform (CDP) has skyrocketed. From e-mail specialists to tag management providers — as long as a product used to offer something with customer data and had some APIs for data input and output, it now is likely called a “CDP”. The CDP Institute’s “Vendor Comparison” lists 53 solutions alone! Let’s try to define a CDP and look at its most important components.

Who is Losing Interest in Adobe Analytics? — 3 Key Indicators

How to Measure User Adoption of your Adobe Analytics Setup and Prevent Co-Workers from Churning
Am I doing a good job in terms of user adoption of Adobe Analytics at my organization? Which co-workers are starting to lose interest? Which ones are emerging Power Users? Which data topics deserve more attention, i.e. enhanced reporting & tracking? Part 1 of this article reviews account logs, their issues and shows 3 key reports Admins should focus on.
The account usage logs of Adobe Analytics offer a lot of cool data to monitor if the Digital Analytics team is doing their job. However, they are not without pitfalls. A Project View may not be what you think it is. How fresh is the data? And how do you deal with the different logging languages? A checklist and some code examples in the Part 2 should help.

Bots & Analytics: Common Failing Approaches to Bot Filtering and how to solve them

From Filtering out Bots to Filtering in Humans
This is the never-ending story in 2 acts on how to deal with Bots in your Google or Adobe Analytics data.

In part 1, I review common, yet usually insufficient or even completely failing approaches. Why did I give up on AI-driven solutions like ReCaptcha, Akamai Bot Manager or Ad Fraud Detection tools? How good are the built-in Bot Filters? Should you at least maintain Bot Filters/Segments on top of GA views/AA Virtual Report Suites? Why does Server-Side Tracking exacerbate the Bot issues?

In part 2, I look at a client who saw Bot Traffic surging to over 40%, a case which made me reconsider entirely how to approach Bot Filtering. We show a 2-layered system which turns traditional approaches upside dow - instead of filtering out Bots, the focus is on filtering in humans.

Also: Check out the video of our presentation (together with David Hermann) at Superweek 2023 on the topic.

Use Google Tag Manager Server-Side for Visitor Stitching by Querying a GCP Database in Real-Time

How to use Server-Side GTM + Pubsub + Python + Firestore to get attributes from a database about a User, Products, or anything

I show (including code examples) how you can use Server-Side Google Tag Manager to enrich client-side data (e.g. from a data layer) by querying a database on the Google Cloud Platform in real-time and returning the output to the (server or browser) client.  It uses Cloud Functions, Template Data Storage for Caching and PubSub to generate asynchronous responses. You can of course query any other data in similar fashion, e.g. sensitive product data (e.g. profit margins) or anything else.

Life with Adobe Launch 3/3: Classic Tag Management skills are not enough

What you need for developing Custom Launch Extensions

In the third part of “Life with Adobe Launch”, I look at the entry bar for developing a Custom Launch Extension in terms of skills and structure. Tag Management specialists tend to have some development skills, but rarely work in the same environments nor with the tools that full-stack developers do. Developing a Launch Extension changes that: You have to learn how to work with the tools of today’s professional developers. Thus, the entry bar may be high. It was for me. But I don’t regret it and learned so many useful things along the way.

Life with Adobe Launch 2/3: Make it scale with a Custom Extension

How to ensure a centralized and scalable data collection standard across websites with a Launch Company Extension

Part I covered the rocky history of Adobe Tag Management Systems (TMS). It also showed that Launch still has many of the scaling issues of its predecessor Dynamic Tag Management (DTM). Fortunately, Launch offers a way out: Custom Extensions. So if you have multiple sites and want them to adhere to a common tracking standard, such an Extension is a must. Otherwise: innovation freeze and data quality disaster.

Life with Adobe Launch (1/3): The rocky history of Adobe Tag Managers

Shining at the fancy things while failing at scaling

As amazing as Adobe is in Analytics, as inglorious is Adobe’s history with Tag Management Systems. Launch is the 3rd TMS in 6 years. After the failed “Adobe Tag Manager”, Adobe “DTM” did the fancy, unimportant things well, but choked at what is most important, especially for large enterprises: scale. Launch still has many of these same problems, but offers solutions now.

Video: How to Create Metrics that Count once per Visit or Visitor in Adobe Analytics

One of the first things a Digital Analyst learns is how to ask “what are we counting exactly?” Visits? Hits? Visitors? Visits with Search? Visits from First-Time Visitors? The answer is often not obvious at all, and some tools only offer very limited counting methods. In Adobe Analytics at least, it is very easy to make things count the way they should. This video shows how.

When the Past Changes: The Technology Behind Profit Margins & Actual Revenue in Analytics (Part II)

Part I showed how important it is to become aware of “Actual” Revenue to counter the “Tracked” Revenue, and why a true Performance Marketer should not look only at the (Tracked) Revenue per Cost (misleadingly called Return on Ad Spend (ROAS)), but at the Profit Margin per Ad Cost. Part I also showed: For such a complete picture, you need to blend a lot of data sources. Thus, part II highlights the components required to get all that data together into Adobe Analytics.

So how many Users do these evil Ad Blockers kill? A Checklist & Guide for Comparing Apples to Apples
