YouTube hashtag guide

Everything about YouTube hashtags

Learn how YouTube hashtags work, how many to use, and how to research the best hashtags for your niche.

Where does YouTube display hashtags?

YouTube shows up to three hashtags above the video title on the watch page, pulled from the first three #hashtags in the video description. All additional hashtags in the description are searchable but not displayed above the title. Hashtags also make your video discoverable via YouTube hashtag search pages.

How many hashtags should a YouTube video have?

YouTube allows up to 15 hashtags per video. Using more than 15 causes YouTube to ignore all hashtags for that video entirely. Best practice is to use 3–8 highly relevant hashtags — a broad category tag, a niche-specific tag, and a few trending tags in your topic area.

What is the difference between YouTube tags and hashtags?

YouTube tags (also called keywords) are metadata entered in YouTube Studio that are hidden from viewers and used to help the algorithm understand video content. Hashtags are visible labels prefixed with # that appear in the video description and make the video searchable by topic. This tool extracts both.

Can I use the same hashtags as popular videos?

Yes. Using hashtags that top-performing videos in your niche use is a valid research strategy. This tool lets you extract exactly which hashtags any video uses so you can incorporate the most relevant ones into your own content.

Do hashtags affect YouTube SEO?

Hashtags primarily help with discovery via hashtag search pages rather than direct ranking. They signal to YouTube what topic your video belongs to and surface it when viewers browse that hashtag. Well-chosen hashtags combined with strong title, description and tags produce the best results.

Why might some videos have no hashtags?

Many creators — especially older videos — do not use #hashtags in their descriptions. The extractor also checks the video's keyword tags as a secondary source. If neither source contains any hashtags or tags, the tool will display a 'no hashtags found' message.
