Tag Management in the web

Tag Management in the web
It’s STILL just JavaScript.

14. The web is inherently stateless.

18. Landing Page, Session, and Touchpoint are terminology of a
stateful machine.

19. Landing Page, Session, and Touchpoint are terminology of a
stateful machine.
The web page feeds data to the server, which builds the data
pipeline. Thus state and sessionization are handled in the backend.

20. Could we introduce state?

21. {"sessionCount": "2", "firstTouch": "cpm"}
Could we introduce state?
Why doesn’t Google Analytics tell us details about
the session in the server response?

23. Forget it.
Let the TMS do what the TMS does
best.

TMS in the organization

25. @SimoAhava from @ReaktorNow
TMS in the organization
Tag Management does not make IT redundant.

26. TMS is a marketer’s tool.

27. TMS is a developer’s tool.

28. TMS is an organization’s tool.

29. Why it’s about marketing.

30. Why it’s about marketing.
1. Tags collect data for digital marketing purposes, first and
foremost.
2. TMS abstracts the underlying code — low barrier of entry
for people with little coding experience.
3. Semantic data collection is easy to deprioritize by
developers who are more invested in the presentational and
experiential layers.

31. Why it’s about development.
1. It’s a freaking code injector!
2. You can add all sorts of malicious / website-breaking /
malware-infested code with the click of a button.
3. If something goes awry, developers will be held
accountable as they own the processes.
4. A TMS can actually make development work easier, too.

32. Why it’s about organizations.
1. Data flows through the entire organization - it doesn’t care
about job titles.
2. Data quality can be compromised at every junction of the
data process - not just collection.
3. Any company/platform/tool/service collects absurd
amounts of data each passing second - only a mature
organization can tackle this overload.

Things you can do with a TMS

34. @SimoAhava from @ReaktorNow
Things you can do with a TMS
And things you perhaps should NOT do…

35. You can customize the page with
hideous exit intent popups.

36. You can write fragile fixes to the
document object model.

37. If you use a TMS to fix issues that
should be fixed in the page
template or site JavaScript, you’re
using it wrong.

39. Things you can do with a TMS, if
the browser doesn’t execute
JavaScript:

40. Things you can do with a TMS, if
the browser doesn’t execute
JavaScript:

41. At its best, a TMS can be used to…
Deploy the latest versions of marketing, advertising, and
analytics trackers with ease.

42. At its best, a TMS can be used to…
Create, manage, and distribute semantic information on the
page.

43. At its best, a TMS can be used to…
Facilitate the agile analytics process - so crucial to any service
development.

44. And more!
1. Proof-of-concept experiential & presentational changes to
get buy-in from developers / HiPPOs.
2. Inject semantic markup (JSON-LD, META)
3. Resolve scripting conflicts on the site.
4. Load 3rd party libraries (e.g. jQuery) asynchronously.
5. Consolidate the codebase, write ad hoc JavaScript, inject
HTML elements, etc.

Data is difficult

Data is difficult
Data quality is earned, not acquired.
