Best practice is to try think of categories as more canonical, so that each product/listing belongs to one category, whereas tags are abundant and freeform.
- Broad: They represent the main topics or sections of your website, much like chapters in a book. They are hierarchical, meaning you can have subcategories within a category.
- Organizational: They help structure content on a high level, guiding users through the site logically.
- Limited: Usually, each post or page should belong to one category to maintain clarity.
- Specific: Tags are specific keywords that describe the details of your content. They are like the terms listed in a book's index.
- Non-hierarchical: They do not have a parent-child relationship like categories.
- Flexible and Abundant: A single post can have multiple tags, allowing it to be associated with various terms.
When to Use Each:
- Use categories when you want to group content into major topics. They are essential for helping users navigate the site and understand what it offers at a glance.
- Use tags to link related content across different categories. They enhance the discoverability of content and help users find all related content on a specific topic or theme.
This helps create a user-friendly experience where visitors can easily browse through broad sections (categories) and then drill down into specific interests (tags).
