A free hashtag generator can speed up brainstorming, but it cannot promise more views. On YouTube, hashtags work as links to related videos and as labels that help viewers find your content. They work best when you generate a short list from what the video actually shows and says, check each phrase against YouTube’s rules, place a small set in the title or description, and then use Analytics to see which search terms viewers really use.
What hashtags do on YouTube
A YouTube hashtag is a word or phrase beginning with # and placed in a video’s title or description. Each hashtag links to a results page of other videos that use it. Viewers reach those pages in three ways: by searching for a hashtag, by selecting one shown on a video, or by finding trending hashtags through Explore. That is the whole mechanism the official guidance describes, and it is why hashtags are about relevance and findability rather than a switch that boosts reach.

Hashtag rules to check before you generate anything
YouTube’s Help pages set several concrete rules. Check these first, because a generator will not know them.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Clear out junk files and repair common Windows errors3Scan for outdated or missing drivers - takes under a minute| Rule | What YouTube’s Help guidance says |
|---|---|
| Where hashtags go | Title and description. You can add a hashtag to either field. |
| Spaces | Not allowed. Join multiword phrases into one string, such as #YouTubeTips. |
| Suggestions | As you type after #, YouTube may suggest popular hashtags. You can choose one or create a relevant hashtag yourself. |
| Display near the title | Up to three hashtags judged most engaging from a video’s description may appear by its title. |
| Count limit | If a video has more than 60 hashtags, YouTube ignores all of them. This is a platform threshold, not a study result. |
| Relevance and policy | Hashtags must describe the actual video. Unrelated or misleading hashtags can be removed or trigger other enforcement. |
The Help pages describe these rules for videos in general. They do not set out separate hashtag behavior for Shorts, so apply the same standard to a Short as you would to any upload.

Do hashtags help videos get views?
YouTube does not say that hashtags guarantee extra views, and it does not describe a ranking or algorithmic preference for them. Its discovery guidance focuses on other elements. The title, thumbnail, and description matter more for discovery than ordinary video tags. The description guidance recommends writing a unique description and placing one or two main descriptive words in both the title and the description. Hashtags fit into that picture as an accurate labeling aid, not a reach multiplier. Any tool that claims AI-generated hashtags will add views is making a claim the platform’s own documentation does not support.
Hashtags, video tags, and keywords are different things
Creators often blur these together. Keep them separate, because each one is added in a different place and plays a different role.
| Element | Where you add it | What YouTube says about its role | Where suggestions come from |
|---|---|---|---|
| Hashtags | Video title or description, beginning with # |
Link to results pages for other videos that share the hashtag | YouTube’s suggestions as you type after #, or your own relevant phrase |
| Video tags | Tag field in YouTube Studio | Play a minimal role in discovery, except for commonly misspelled terms | Entered by the creator |
| Keyword research | Outside the upload, in research tools | YouTube recommends the Analytics Research tab and Google Ads Keyword Planner for finding keywords and synonyms | Research tools, not the video itself |
| Viewer search terms | Read-only report in YouTube Analytics | The “How viewers find your” report shows search terms viewers actually used | Your channel’s own viewing data |
A generator belongs in the first row’s workflow. It helps you produce hashtag candidates. It does not replace the title, thumbnail, description, or the search data that shows what viewers look for.
Where do I put hashtags on a YouTube video?
Put them in both the title and the description, but for different purposes. The description is the natural home for a full set, because YouTube draws its near-title display from hashtags in the description. In the title, use a hashtag only if it names the main subject of the video, and pair it with the one or two plain-language descriptive words that matter most. A title stuffed with hashtags reads poorly and gives viewers no reason to click.
How to use a generator without padding your video
Treat the generator as a brainstorming step inside a review process. The steps below follow YouTube’s guidance; they are a practical workflow, not a documented ranking formula.
- Write one sentence describing the video: the subject, the intended audience, the format (Short or longer upload), and the language you will speak and caption in.
- Generate a short list of candidate hashtags from that sentence. Ask for a list of phrases you could defend, not the largest list the tool will return.
- Watch or re-read the video and check each candidate against what is actually shown and said in it.
- Remove anything that fails the checklist below.
- Join every multiword phrase into a single string with no spaces, and check the spelling of each tag.
- In the title or description field, type
#and compare your candidates with YouTube’s suggestions. Choose a suggested tag only if it describes this video. - Keep the final set small. Add the one or two main descriptive words to the title and description as plain text.
- After publishing, check YouTube Analytics for the search terms viewers used, and adjust future uploads based on that evidence.
Review checklist for every candidate
- It describes something specific in this video, not just a popular topic it touches.
- It is not a trending term that has no meaningful connection to the content.
- It contains no spaces and no misspellings.
- It is not a duplicate of another hashtag you already chose.
- It would not mislead a viewer about what the video contains.
- It fits the language you are publishing in.
How many hashtags should you use?
The 60-hashtag limit is a ceiling, not a target. Adding more hashtags does not add more value, and every extra phrase that fails the checklist makes the set less accurate. A small set of relevant hashtags is easier for viewers to understand and easier for you to defend if YouTube questions a tag. Once you have a short list that passes review, stop.

Use Analytics to find out which search terms work
The most reliable input for your next upload is the viewers’ own search behavior. Open the “How viewers find your” report in YouTube Analytics to see the search terms viewers used to find your videos. Compare those terms with the hashtags you chose. If viewers search for a phrase that is missing from your title and description, add it in plain language where it fits naturally. If a hashtag you chose never appears in that data, it may still be accurate, but it is not doing the work you hoped.

#. You can still create a relevant hashtag yourself. Check that it has no spaces and is spelled exactly as you intend. - A hashtag does not appear near the title. Only up to three hashtags judged most engaging from the description are shown there. The rest still function as links in the description.
- None of your hashtags appear to function. Check the total count. More than 60 hashtags on a video means YouTube ignores all of them.
- A hashtag was removed. Check whether it describes the actual video. Unrelated or misleading hashtags can be removed or trigger other enforcement.
- Traffic has not changed. This is expected if the hashtags were the only change. Review the title, thumbnail, and description, then check Analytics rather than adding more hashtags.
What to look for in a free hashtag generator
Choose a generator on the criteria that affect the workflow above, not on promises about reach. Compare tools on these axes:
- Relevance to the actual video. Can you give it the subject, audience, and format, and does it return phrases tied to them?
- Language and audience fit. Does it handle the language you publish in, and does it avoid generic phrasing for a specialized audience?
- Review speed. Can you check, edit, and reject candidates quickly, without the tool filling your list with trending noise?
- Link to real search data. Does it help you connect candidates to what viewers search for, or does it stop at a list? YouTube’s own keyword recommendations come from Analytics Research and Google Ads Keyword Planner, which are separate from its built-in hashtag suggestions.
Whatever tool you use, the platform rules and the review checklist still apply. A generator can produce candidates quickly, but the decision about what belongs on your video remains yours.
