How do you handle Wikipedia categories and how do they affect visibility?

Wikipedia’s category system is the navigational backbone of the encyclopedia. Every article is tagged into one or more categories – by industry, geography, type of organization, era of founding, notable affiliations, and so on – and those categories propagate into navigation, related-article suggestions, and structured queries that AI engines can pull from. Correct categorization matters for two practical reasons: it makes the article findable by readers browsing topics rather than searching by name, and it strengthens the entity signals that flow to Wikidata, the Google Knowledge Graph, and the AI engines that read from both. Incorrect categorization – a private company tagged as a public one, a fund tagged in the wrong investment category, a founder’s biography in the wrong nationality bucket – propagates the error widely. Category corrections go through the standard Talk-page workflow.
