Will adding chapters guarantee more views?\u003C/h3>\u003Cp>No guarantee, but chapters improve user experience and can increase CTR for segments and overall watch time. They’re a low-effort, high-utility change that usually yields positive results when paired with good thumbnails and titles.\u003C/p>\u003Ch3>4. Should I add transcripts to the video description or upload captions?\u003C/h3>\u003Cp>Do both if possible. Uploading captions (.srt) ensures accurate on-screen captions and accessibility. Adding a transcript in the description provides extra crawlable text for search engines. Edited auto-captions are better than uncorrected auto-generated captions.\u003C/p>\u003Ch3>5. How often should I re-optimize older videos?\u003C/h3>\u003Cp>Quarterly audits are a good cadence. Prioritize videos with high impressions but low CTR, or high CTR but low retention.
