Not every label does the same job. Navigation labels derive much of their meaning from the hierarchy they sit within, and the labels leading to a home page or section main pages carry the most weight of all. Indexing terms, categories, tags, keywords assigned through a CMS, support both browsing and search at once, and often draw from a controlled vocabulary to stay consistent. Filtering control labels need to clearly represent the scope of what a checkbox or dropdown actually narrows, especially when several filters sit inside a collapsed group. Contextual link labels within body content can afford to be generic, "Learn More" works fine when the surrounding text and page title already provide context, but a reference link to another page should generally use that page's actual title. Page titles orient a user by confirming where they've landed, ideally echoing the language of whatever link brought them there, while subheadings structure the content within the page itself.
A confusing label rarely announces which type it is, but tracing a user's hesitation back to the specific type of label that failed them is usually the fastest way to know exactly what to fix.
1: Navigation label failure. "Programs" versus "Courses" as ambiguous top-level navigation options, with no further context to disambiguate them, is a direct navigation labeling problem.
2: Filtering control failure. A filter labeled "Level 1" with no explanation of what that level actually means fails to represent the scope it controls, exactly what a filtering label needs to do.
3: Page title failure. A missing page title means she has no confirmation of where she's landed, the core job a page title exists to do.
4: Contextual link failure. A generic "Learn More" link dropped with no surrounding context provides no information scent at all about what it leads to.
"Learn More" is not inherently a bad label, the source material is clear that generic contextual labels like this work fine when the surrounding context does the work of clarifying their destination. If this link had appeared directly beneath a subheading like "Instructor Qualifications," or immediately after a sentence introducing the instructor by name, "Learn More" would clearly and reasonably point toward more detail on that specific topic. The failure here isn't the words themselves: it's that the label was dropped with no heading, no introductory sentence, and no surrounding context at all to anchor its meaning.
