Content Freshness
In one sentence
Whether the content is current, and how recently it genuinely changed.
Analogy Mental model
The date on the milk. Fresher is better, and past the date it is no longer the same product.
In practice What you actually do
For time-sensitive subjects, revise on a schedule, put the current year in the title, and update the examples rather than the timestamp. For evergreen pages, leave them alone until something in the world actually changes.
Where people get burned Pitfalls
Changing only the date is the oldest trick and the easiest to detect, because the engine sees both versions. What counts is new data, corrected facts, added sections, removed dead references.
