Collect visitor role information via analytics

[ralf57]

Overview

This issue depends on #158
The idea is to ask the ADG visitors in which role they are using/visiting the ADG website.
The collected data would help us with the definition of different UX personas.

Example

Question: How are you using the guide?
Answers:

• as a developer on a project
• as a bizdev
• as an accessibility enthusiast willing to learn more

@gracischuetz could help crafting the form

Notes:

• answering is totally optional and is done voluntarily by the visitor
• the data is directly submitted to Matomo (via event tracking, no other storage is required)

Hi! As spoken with @ralf57 Donato, here is a way of asking the visitors their role and what they were looking for. Wireframes Asking for Feedback
(By the way, hotjar do that out of the box https://www.hotjar.com)
The idea is to place a closable overlay at the bottom right side of the website asking for two questions:

1. Which specific topic were you looking for?
2. What is your role?

Afert sending the feedback, a thank you message appears:

Would that be possible? Can I help somehow?

Thanks @gracischuetz
I will sync with @renestalder in order to start using the available Matomo instance and implement this feature.

The solution will leverage Matomo's Event Tracking and the proposed structure is:

_paq.push(['trackEvent', 'Form - Feedback', 'Submit', 'TOPIC || ROLE']);

which allows the logging of both the topic and the role.

Closed after today's backlog grooming. Feel free to reopen at any time, ideally based on a specific data requirement.
