In which case you would create a taxonomy term, and in which case just a section?

Both look very similar, so I was wondering in which case would be appropriate to use a taxonomy over a section.

Let’s say my website has a section called “posts”, under posts there are other sections “experiences”, “events” holding posts.

“events” and “experiences” could be a good way to categorize content, therefore my first thought is to create a category term for events and one for experiences.. However this way I’d have two duplicate pages, eg. for events:

  • categories/events
  • posts/events

Is there an actual difference, or these are virtually the same? What would be the advantage of using a taxonomy rather than a section? Maybe when I can have more terms for one post?

I would say this one

have a look at Content Management Taxonomies

benefits:

  • multiple values per page
  • own pages for the taxonomy and the terms to add additional content

so if your pages are either events or experiences a section is fine.

This is a classic content modeling question.

Think of a top level content directory as a content type.

A post is one content type, with metadata (front matter) that might include a title only. The template to render posts is probably unique (e.g., layouts/posts/page.html).

An event is another content type. Its metadata might include things like start/stop times, locations, speakers, links to registration pages, etc. The metadata is fundamentally different than that of a post, as is its template (e.g., layouts/events/page.html).

You might assign taxonomy terms to either one. A given term might apply to one or more content types. For example, the terms in a “topics” taxonomy might be used by both content types (e.g, topics = ['legislation', 'litigation'].

Gemini provided this explanation:

Content types define the structure and fields for a piece of content, while taxonomy provides a system for classifying and organizing that content. Think of it like this: content types are the “boxes” you create to hold information, and taxonomy helps you label those boxes with categories and tags so you can find them later.

I would add that taxonomies are great for listing related content in a sidebar.
