Content decay is the gradual decline in organic traffic and rankings for older posts that used to perform well. It happens because information becomes outdated, competitors publish fresher content, or search intent shifts.
refreshing decaying content often has a higher ROI than writing net-new articles. It's easier to push a page from pos 6 to pos 1 than to start from scratch.
