Some were because of UA, other were pure hallucinations

That's the whole point of the question and how GA treats sessions. Even if the user comes from a different source during an active session, the session is also not started. This is very similar to as if a visitor came to the site directly again in the middle of session

User comes from Google > User comes from Instagram > Closes tab > opens a new browser tab and enters your website's address. This could be an example of coming directly.

Use less of "Artificial" and more of "Human" intelligence :) Then PhD becomes optional

Fun fact: Gemini got several answers right, but the explanations were completely wrong. So, I guess the final score should be even lower

Think you know Google Analytics 4? Even Gemini only got a 70% on my new skill test😬

40 questions. 30 minutes.

It's a challenge, but if you want to prove you're an expert, aim for that 40/40.

Here's the action plan I would like you to do:
1. Read the guide, maybe you'll learn something new
2. Maybe you've spotted one more reason why the event gets missing? Please let me know and I will gladly update the article. Let's expand this troubleshooting guide together

I did a bunch of experiments trying to figure out when does it get lost and this blog post is the result. Some tests succeeded and others failed.

This is NOT "a definitive guide". I think there are still many *unknowns*. But I think it's a good start.

session_start event is missing in GA4? Here are the reasons and solutions - Analytics Mania Learn the common reasons why the session_start event is missing in GA4 and discover solutions to prevent tracking issues and improve accuracy.

🚨New blog post
This time, about the missing session_start event in Google Analytics.

It's a pain in the ass, which sometimes "just happens" and we end up with "not set" traffic sources.

❌ There will be no Christmas sale.
❌ No "end of year" sale.

This is your best chance in 2025 if you've been eyeing the courses for a while.

P.S. if you are an existing student of my courses, check your inbox. I sent you another offer a couple of days ago.

The Black Friday sale on my courses is live, and I have prepared a bunch of bonuses (some brand new).

Even though it sounds cliché, this is my best offer of the year.

In the same amount of time, I managed to show more ways you can benefit from SGTM

🎉 To celebrate this, I just launched a sale buff.ly/SdXsEDk

Whether you want to master SGTM, learn JavaScript for GTM, or become really good with GA4, now is the perfect time

3/4

Why did I move the curriculum from GCP to Stape?
👉 It's easier to use
👉 It costs less (but still reliable)

The new modules focus less on server administration and more on powerful things you can do right away - like connecting SGTM to your CRM or enriching events.

2/4

My Intermediate/advanced GTM course just got a major update

For a long time, I was mainly using Google Cloud Platform. While powerful, it's also complex. For many people, it was a high entry barrier. Thus, I've re-recorded SGTM lessons in my course

No, user_engagement before page_view does not cause "not set" landing page Learn why user_engagement before page_view does not cause a “not set” landing page and how my experiments helped debunk this myth.

Now, we have a different version of Google Analytics, but the same myth: that if an event (e.g., user_engagement) fires before a pageview in GA4, it will cause the Landing page to be not set

Not true. I have run several tests to prove that point.

Time to bust a myth.

We had something similar in Universal Analytics when people believed that if you have any event tracked before page view (in the same session), this will cause “not set” landing page. Simo debunked that a while ago.

🎂 On this day, 5 years ago, I published my first YouTube video

I had dreams but never actually expected it to grow that much. Currently at 140k subs

Yes, those are rookie numbers compared to largest channels, but in our niche, the result is pretty good :)
