User intent, also called search intent, is what someone actually wants when they type a query, distinct from the literal words of the query itself. "Apple" could mean the fruit, the company, a recipe, or a product page, and a search engine's whole job is inferring which one a specific searcher actually meant from context and behavior patterns.
It's usually grouped into four broad categories: informational (wanting to learn something), navigational (trying to reach a specific site), commercial (researching before a purchase), and transactional (ready to buy or act now). Content built for the wrong intent tends to fail even when it's genuinely well-written and technically well-optimized: a product page competing for a query that's actually informational will struggle regardless of quality, since it's answering a different question than the one being asked. Matching intent correctly is arguably more foundational than any single on-page tactic, since a page that gets the intent wrong is fighting an uphill battle no amount of keyword optimization or technical polish can fully compensate for; a visitor landing on a mismatched page tends to leave immediately, and those quick exits are exactly the kind of signal that reinforces to search engines that the match was wrong in the first place.
