Website maintenance is the continuing care required after launch. It can include publishing content, fixing interactions, updating dependencies, checking forms, reviewing accessibility and resolving browser issues. Improvements are intentional changes such as refining navigation, clarifying a page or making a component easier to use.
The right level depends on the website’s condition and purpose. A small correction should not become a rebuild, while a fragile platform may make repeated fixes inefficient. We distinguish maintenance, enhancement, redesign and redevelopment so each decision has an appropriate scope.
