How YouTube hashtags work
Hashtags on YouTube work differently from Instagram. Adding a hashtag to your description makes it appear as a clickable link above the title on the video watch page, and adds your video to that hashtag's feed. The first three hashtags you add are displayed above the title; any beyond that are stored but not shown.
YouTube uses hashtags as a categorisation signal, not a primary ranking factor. They help with discovery in hashtag browse pages and occasionally in search, but they do not substitute for keyword optimisation in the title and description.
Broad, niche, and branded hashtags
A working hashtag strategy uses three types. Broad hashtags like #YouTubeSEO have millions of videos and low visibility but occasionally surface your content to a large audience. Niche hashtags like #YouTubeSEOTips have a smaller pool and a higher chance of appearing in the feed. Branded hashtags like #VidSEOKit tie your content together in a navigable collection.
The generator suggests a mix of all three for every topic: one or two broad category tags, two or three mid-sized niche tags, and one branded tag. Use five hashtags total: the first three are the ones viewers see, so they should be your strongest niche-specific choices.
Frequently asked questions
How many hashtags should I add to a YouTube video?
Add three to five. YouTube displays the first three above the title — those are the ones viewers see and click. Adding more than fifteen hashtags triggers a policy that removes all hashtags from the video, so stay well under that limit.
Do hashtags increase YouTube views?
Hashtags contribute marginally to discovery through hashtag feeds and browse pages. They are a secondary signal. The primary drivers of YouTube views remain title, thumbnail, and audience retention — hashtags supplement those, not replace them.
Should hashtags match my keywords?
They should overlap but not duplicate. Your target keyword belongs in the title and description. The hashtag version of that keyword — #YouTubeSEO rather than the phrase "youtube seo" — belongs in the hashtag list. They reinforce each other rather than competing.
Can hashtags get my video penalised?
Using misleading hashtags — tagging a cooking video with #gaming to poach views — violates YouTube's spam policy and can result in strikes or reduced reach. Stay accurate and relevant.
