Today’s issue is more technical than usual: best practices for tagging and tag managers (with lots of examples) or multi-channel attribution modeling (with probably even more examples).
But there are also two detailed and interesting case studies: Sephora crushing it in digital and a revamped email flow that generated $500k in revenue.
At the very end: some funny and sad stuff, too. Don’t miss it.

Multi-Channel Attribution Modeling: The Good, Bad and Ugly Models [Occam’s Razor]

By the time you are done with this article, you’ll have complete knowledge of what’s ugly and bad when it comes to attribution modeling. You’ll know how to use the good model, even if it is far from perfect, and the often hidden nuances.
What multi-channel attribution models are out there?
- Last Interaction/Last Click Attribution model.
- Last Non-Direct Click Attribution Model.
- Last AdWords Click Attribution Model.
- First Interaction/First Click Attribution Model.
- Linear Attribution Model.
- Time Decay Attribution Model.
- Position Based Attribution Model.
- Customized/Personalized Attribution Model.
Most important takeaway: last click model, which is the default in most analytics tools, tells the wrong story for most businesses. Don’t use it, unless you know what you’re doing. Read more about other models and decide which one works best for you. Or create your own.

PS. I don’t have a complicated welcome email flow, a single simple welcome email. Also, after signing up visitors land on a welcome landing page. On that page, I ask a single quesion: “What was going on in your life that brought you to try GrowRevenue today?”
Some answers are funny: “I don’t do the next step in my life. . . everything looks teadious and I have been thinking of doing fraud which can’t help me, if this organisation will help me to stand out and grow in all aspects of my life .majorly financially…. I will be glad”
But some are sad: “My start up is suffering from income deficiency”
On that note: let your startup (or life) never suffer from income deficiency!
