A topic goes stale when its core answer stops matching reality, when the viewers who used to search for it move on to a new phrasing, or when the video slowly loses traffic with nothing replacing it.
Stale is not the same as old. Plenty of five-year-old videos are still climbing. Age is a clue, but the numbers decide.
Total views only tell you what a video did in the past. What matters is views per day over a rolling month, because that is what the video contributes right now. A video with a huge lifetime total can be earning almost nothing today.
Pull that number for your older uploads each quarter and compare it to itself thirty days earlier. A steady decline over several months is the clearest stale signal you can get, and it shows up long before the total looks scary.
First, the facts in the video are now wrong. Prices changed, a tool shut down, a rule was rewritten. Wrong answers age a video fast, and viewers notice.
Second, the search phrasing moved. If everyone used to type one phrase and now types another, your title is chasing a query that no longer has traffic.
Third, the need itself faded. Some questions genuinely stop being asked as habits change, and no update will bring the audience back because there is no audience left to bring.
Retiring a stale video is not failure. Keeping dead weight on the shelf just makes the whole library look tired.
When the underlying need is still alive, refresh the video: correct the facts, update the phrasing in the title, and patch the description. You keep the ranking history and the video earns again.
When the need is gone, retire it. Unlist the video so it stops surfacing, or leave it up as an archive if some viewers still arrive. Either way, stop counting it as part of the active library and free the topic slot for something that still has demand.
Sort your uploads older than a year by views per day and look at the bottom twenty. Five minutes per video tells you whether each one needs a patch, a retitle, or retirement.
The sweep usually saves two or three videos that were quietly dying and frees you from maintaining the rest. Both outcomes make your library stronger than it was before you started.
Evergreen content keeps earning views for years, and a video earns that label when its topic, answer, and title still work long after publish day.
Evergreen content starts at topic selection, so the topics that age well are the ones tied to recurring needs rather than a moment, a price, or a release.
A healthy channel mixes evergreen content with timely uploads, because search builds the floor while trends buy short bursts of new attention.
