You have a handful of articles or pages and want to group them by interest so visitors can find what matters to them. The common mistake at this stage is setting up a full category tree before the content exists to fill it. The result is a navigation menu with several links that lead to empty pages or placeholder text, which signals to readers that the site is unfinished. A workable approach is to derive your groupings from what you already have. List every piece of content you currently own, then look for natural clusters of two or three items that share a theme. Create a section only for each cluster you can actually populate today.
Duplicate entry points are a related problem. They appear when the same page is reachable through two or more category links, or when a tag and a category point to the same small set of items. For a reader this creates confusion about whether they have already seen something or whether two sections are meant to be different. To catch this, trace every path from your top-level navigation down to individual pages and note which pages appear more than once. If a page shows up under two headings, decide which heading is the more natural home and remove the other link, or merge the two headings if they overlap heavily.
As your content grows, revisit the structure rather than locking it in early. A section that started with two items might eventually hold ten, and that is the point at which splitting it into sub-sections makes sense. Until then, a flat list of a few broad interest areas serves readers better than a deep hierarchy with gaps. The guiding principle is simple: every visible section should contain enough material to justify a click, and every piece of content should have one obvious home.
