Custom Post Type (CPT)

A Custom Post Type (CPT) is a WordPress content structure beyond the built-in posts and pages — used to model distinct entities like case studies, team members, glossary entries, or events with their own admin UI, URL structure, and editorial workflow.

When to use a CPT

• The content is structurally distinct: a Case Study isn’t just a blog post with a different category.
• You want a dedicated archive URL and discoverable single pages.
• You need custom fields, taxonomies, or admin role permissions specific to this content.
• Editorial roles need to find these items in their own menu rather than buried under “Posts”.

When NOT to use one

• The content is functionally the same as a blog post but tagged differently — use a category or taxonomy.
• You only need a handful of singletons (About, Contact) — those should be Pages.
• The structure is so dynamic it would be easier modeled as a relational data store called from a custom plugin.
