Relevance
The degree to which a page's subject and substance match what the person typing actually wanted.
Analogy Mental model
You order beef noodles. The chef's pizza may be excellent, but it is not the order. Relevance is about serving the dish that was asked for, not the dish you are proudest of.
In practice What you actually do
Build topical coverage instead of repeating a keyword. If the subject is coffee roasting, the page should naturally reach light roast, dark roast, roast curve, first crack and degassing, because a reader who knows the field expects them. The vocabulary is evidence that you know the territory.
Where people get burned Pitfalls
Slipping a trending keyword into an unrelated page is the oldest trick in the book and the easiest one to catch. It reads as noise to people and as manipulation to the classifier.
