As of July 2022 Youtube has updated the way in which Hashtags are processed and displayed. These changes are explained below.
Please note now this selection is automated on Youtubes side we are unable to request for them to display or elevate specific hashtags.
Q: Creator added in one/two/three hashtag(s), but it isn’t showing up on the video page. Why?
A: Hashtags may not appear below a video title for a number of reasons. For example, hashtags that violate Youtube policies or contain borderline content won’t show below your video’s title and may be removed. Your hashtags will still appear in your video description, and your videos can still appear in search results or hashtag pages for those hashtags.
Q. Why is YouTube deciding to elevate only certain hashtags on a creator’s video page?
A: YouTube’s recommendations systems provide a real-time feedback loop to identify the most engaging hashtags based off of the creator’s inputs. The elevated hashtags should help viewers find videos they are likely to be interested in and offer greater visibility for a creator’s video.
Q: If a creator’s hashtags aren’t elevated on the watch page, will this impact the Search & Discoverability of their video(s)?
A: No, hashtag visibility on the watch page has no impact on search and discovery.
