This document discusses using R to help document a website's Google Tag Manager setup for a DPO. It describes cleaning up unused tags, documenting tags, triggers, and variables using R, and automating the documentation process by having R pull information from GTM and add prewritten descriptions to a Markdown report. This provides documentation for the DPO while cleaning up the tag setup. Code and a working example are provided to demonstrate how to reproduce the documentation process using R and Markdown.

8. SO, HOW
DID THIS ALL START UP?

9. T h e r e a r e m u l t i p l e n e t w o r k c a l l s o n e a c h

10. • DPO’s have no idea of what the
marketeers are doing
• The marketeers have no idea of
what the tools they are using are
sharing with third party
applications
• The developers have no idea of
what the marketeers added into
Google Tag Manager
THE CLIENTS ARE
LITTERALY ASKING FOR IT

11. So i looked into different solutions

12. In terms of documentation - Simos
visualization didn’t quite cut it

13. Spring cleaning
And documenting the setup
WHAT EFFORTS DID WE DO?
Setting up Conditions
Fromboth the datalayerand
cookies
Automating it
To createa quck setup fornew
clients

14. SPRING CLEANING
AND DOCUMENTATION

15. First the spring cleaning

16. First the spring cleaning

20. How it is done

21. THIS GIVES US MORE CONTROL &
UNDERSTANDING FOR THE SETUP

22. THEN WE USED R TO DOCUMENT
THE STRUCTURE

GTM GDPR Framework
By having most of the work
written already, we can
simply say that ”If there is
any tags called facebook, then
add the facebook part to the
documentation”.

44. MAKING THE MOST OF IT
WITH AUTOMATION
1. Pull down GTM info with R
2. If any tags matches known
marketing tags add a
prebuid tag description to
the markdown document
3. Produce, send and make the
DPO happy

45. It is a ”Two birds, one stone” way of
doing it
