Doing a live audit of old videos is one of the most underrated growth hacks. Start by identifying underperforming content with decent topics but low CTR, retention, or engagement. Update the <strong data-start="240" data-end="265">titles and thumbnails first&mdash;make them clearer, more clickable, and keyword-optimized. Next, check the <strong data-start="346" data-end="389">descriptions, tags, and pinned comments&mdash;are they SEO-friendly and driving action? Rewatch the video: is the intro dragging, or is the call-to-action too late? Trim slow sections or add new <strong data-start="539" data-end="554">end screens and cards to boost watch time. Comment and re-share the video to re-engage your audience. This simple refresh can give your old content new life&mdash;and if done regularly, it becomes a powerful way to boost channel growth with content you already have.
