A multi-topic publication becomes confusing when every organizing label is treated as a category. Marketing, book summaries, tutorials and ChatGPT do not describe the same kind of thing—and the CMS should not pretend that they do.
Four dimensions do four different jobs
Topic answers what the piece is about. Format answers what kind of piece it is. Series creates a deliberate reading sequence. Tags capture the specific concepts, tools and technologies inside it.
- Topic: Finance
- Format: Book Summary
- Series: Books That Changed How I Work
- Tags: Behavior, investing, decision-making
Classification can change while the URL stays stable
An article may move from one topic to another as the publication matures. Keeping the topic out of the article URL prevents editorial improvements from breaking links.
A controlled vocabulary is a design decision
The CMS should make the right structure easier than the wrong one. One primary topic, one format, a maximum of two related topics and a small number of tags are enough for most pieces.
Key takeaways
- Subjects and content types are different dimensions.
- Stable article URLs allow classification to evolve.
- Editorial constraints preserve discoverability as the archive grows.
