Good tags are not decoration. They are routing signals for people and crawlers.
Define a small vocabulary
Keep a short set of recurring tags instead of inventing new ones for every article.
If you are new to this template, start with Hello World and then apply the process in Internal Linking Playbook for Fast-Growing Blogs.
Review overlaps before publishing
Before opening a PR, confirm the post shares at least one meaningful tag with existing content.
That overlap gives the related-post surface enough signal to recommend useful follow-up reading.
Keep maintenance simple
Every month, scan the tag archive and merge near-duplicate tags. Fewer, clearer tags produce stronger clusters.
