HASHTAGS OR HASHBROWNS: Using the Right Tags for Your Videos
Tags and hashtags are not the same thing, they do not work the same way, and using them wrong is actively hurting your discoverability. Here is the definitive guide.

Ask ten YouTube creators how to use tags and hashtags and you will get ten different answers — most of them confidently wrong. Some creators stuff every tag field with hundreds of keywords hoping to catch every possible search. Others ignore tags entirely on the assumption that the algorithm has made them irrelevant. A third group uses hashtags as glorified labels with no strategic thought about placement, quantity, or relationship to the content. None of these approaches is correct. Tags and hashtags serve distinct, specific functions in YouTube's discovery system — and using each one correctly, in the right context, with the right quantity, produces measurably better results than the alternatives.
Tags vs. Hashtags: Two Different Tools
The first and most important thing to understand is that YouTube tags and YouTube hashtags are entirely separate features with different mechanics, different visibility rules, and different impacts on discovery. Conflating them — or using the terms interchangeably — is the root cause of most bad advice on this topic.
| YouTube Tags | YouTube Hashtags | |
|---|---|---|
| Where Added | Dedicated "Tags" field in YouTube Studio upload flow | In the video description (preceded by #) or in the title |
| Viewer Visibility | Not visible to viewers | Visible above the video title. Clickable links. |
| Primary Function | Contextual signals to help YouTube understand video content and fix common spelling variants | Discovery via hashtag pages. Topical grouping. Category signalling. |
| Recommended Quantity | 5–8 highly relevant tags | 3–5 hashtags per video |
| Impact on Search Ranking | Minor supporting signal. Title and description carry far more weight. | Minimal direct ranking impact. More useful for content categorisation. |
The tag weight myth: YouTube has publicly confirmed that tags are a minor ranking signal — significantly less influential than title, description, and thumbnail performance. Spending an hour researching and optimising 50 tags will produce a smaller SEO improvement than spending 10 minutes improving your title. Tags matter; they just do not matter as much as most creators have been led to believe.
Tags: How to Use Them Correctly
The function of YouTube tags is to provide contextual support for the algorithm's understanding of your video — particularly in cases where the title and description alone might be ambiguous, or where common misspellings of your primary topic exist. Tags are not a primary SEO tool. They are a supporting signal that fills gaps the title and description leave open.
Include Your Primary Keyword
Your exact primary keyword — the same phrase used in your title — should be your first tag. This creates a consistent, reinforced signal across all three text fields YouTube reads: title, description, and tags.
Include Common Misspellings
If your topic has a commonly misspelled variant that viewers might search for, include it as a tag. This is one of the genuinely unique use cases for tags that cannot be replicated in the title or description without damaging readability.
Include Your Channel Name
Adding your channel name as a tag helps YouTube associate your videos with each other in the "More from this channel" recommendation context — particularly useful for newer channels with smaller back catalogues.
Do Not Over-Tag
YouTube has indicated that using irrelevant or excessive tags can negatively affect a video's ranking — treating it as a signal of low-quality or manipulative metadata. 5 to 8 precise, relevant tags consistently outperform 50 loosely related ones. Quality over quantity applies here absolutely.
Hashtags: Placement, Quantity, and Strategy
Hashtags added to a video description appear as blue, clickable links above the video title on the watch page. When a viewer clicks a hashtag, they are taken to a hashtag landing page showing other videos that have used the same hashtag. The primary benefit of hashtags is therefore discovery via browsing rather than search — connecting your video to a stream of topically related content that an interested viewer might be exploring.
Where to Place Hashtags
Hashtags should be placed at the end of the video description — after all other content. Placing them at the start wastes the 150-character first-impression window on non-indexed symbols rather than readable keyword-rich content. YouTube displays a maximum of three hashtags above the video title, drawn from the first hashtags listed in the description, regardless of how many you include. Always place your three most important hashtags first.
How Many Hashtags to Use
YouTube's official guidance recommends no more than 15 hashtags per video. Using more than 15 causes YouTube to ignore all hashtags on that video entirely — a hard penalty for over-tagging. In practice, 3 to 5 targeted hashtags perform better than the maximum 15, because each hashtag places your video in a specific stream of content, and appearing in 5 targeted streams is more valuable than appearing in 15 diluted ones.
Choosing the Right Hashtags
| Hashtag Type | Example | When to Use |
|---|---|---|
| Broad Category | #PersonalFinance | Always — establishes the niche context for the video. |
| Specific Topic | #BudgetingTips | Always — the specific subject covered in this video. |
| Channel Brand | #YourChannelName | Always — builds a browsable hashtag library for your own content. |
| Trending / Seasonal | #TaxSeason2026 | When relevant — places the video in active, time-bound discovery streams. |
| Format Descriptor | #HowTo #Tutorial | For tutorial and educational content where the format descriptor has search utility. |
Do not use misleading hashtags. Using hashtags for popular topics unrelated to your video — to "borrow" traffic from trending subjects — is a policy violation under YouTube's spam and deceptive practices guidelines. Beyond the policy risk, irrelevant hashtags place your video in streams where it will earn low CTR and poor retention, sending negative signals to the algorithm about your content's quality.
"Three well-chosen hashtags in the right streams outperform fifteen random ones every time. The goal is targeted placement in audiences who will actually watch — not maximum coverage of audiences who will not."
Conclusion
Tags and hashtags are supporting tools in a discovery system where title, thumbnail, and audience retention do the heavy lifting. Used correctly, they improve contextual understanding, enable hashtag browsing discovery, and help the algorithm associate your videos with the right audience. Used incorrectly — through over-tagging, irrelevant hashtags, or the confusion of one system for the other — they can actively suppress performance. The correct approach is simple: 5 to 8 precise tags that support your title keyword, and 3 to 5 carefully chosen hashtags that place your video in the discovery streams where your ideal viewer is already browsing. Apply this consistently across every upload and the cumulative benefit to channel discoverability is real, even if no single video shows a dramatic overnight change.
