YouTube Tags vs Hashtags: What's the Difference?

If you're new to YouTube, it's easy to assume that tags and hashtags are the same thing. After all, they're both words or phrases related to your video, and they're both used to help organise content.

In reality, they serve very different purposes.

Understanding the difference can help you spend your time on the things that actually make your videos easier to discover. It can also prevent a common mistake many new creators make—treating hashtags and tags as if they were interchangeable.

Let's look at how each one works and when you should use them.

What Are YouTube Tags?

Tags are pieces of metadata that creators can add when uploading a video.

They aren't normally visible to viewers watching the video. Instead, they're used behind the scenes to give YouTube extra context about your content.

For example, if you've uploaded a tutorial about repairing a bicycle tyre, your tags might include:

bicycle repair
bike maintenance
flat tyre
cycling tutorial

The purpose of these tags is to describe the topic accurately, not to attract attention.

What Are YouTube Hashtags?

Hashtags are different.

They're visible to viewers and are written with the # symbol, such as:

#Photography
#Travel
#Cooking

Hashtags can appear above a video's title or inside the description. Clicking one allows viewers to explore other public videos using the same hashtag.

Unlike tags, hashtags are designed for navigation and discovery by viewers.

The Biggest Difference

The easiest way to remember the difference is this:

Tags help describe your video behind the scenes.

Hashtags help viewers discover related content.

Although both provide context, they're used in completely different ways.

Should You Use Both?

In most cases, yes.

Adding a few relevant tags helps provide additional information about your video, while carefully chosen hashtags make it easier for viewers to explore related topics.

The important word here is relevant.

Neither tags nor hashtags should be filled with unrelated keywords simply because they're popular.

Do Hashtags Affect Rankings?

Hashtags can help organise content and improve discoverability for people browsing similar topics.

However, they're only one small part of YouTube's recommendation system.

Just like tags, hashtags won't compensate for weak content, misleading thumbnails or poor viewer engagement.

If people enjoy watching your videos, that's far more valuable than using dozens of hashtags.

Common Mistakes

Using Too Many Hashtags

Adding a long list of hashtags can make your description look cluttered and less useful.

Choose only the ones that genuinely relate to your video.

Treating Tags Like Hashtags

Some creators expect tags to appear publicly like hashtags. They don't.

Tags are separate metadata that viewers don't normally see.

Chasing Trending Keywords

Adding unrelated hashtags or tags simply because they're popular isn't a good long-term strategy.

Your metadata should always match your content.

Which One Is More Important?

Neither should be your main focus.

Instead, prioritise:

Creating useful content.
Writing a clear title.
Designing an engaging thumbnail.
Writing an informative description.
Adding relevant tags.
Including a few suitable hashtags when appropriate.

This creates a balanced approach that serves both viewers and search systems.

Research Tags the Smart Way

If you're curious about how creators describe similar videos, looking at publicly available tags can be a useful research technique.

Toolerd's YouTube Tag Extractor lets you view the tags associated with public YouTube videos. Instead of copying them, use them to understand common terminology and identify ideas that genuinely fit your own content.

Originality is always more valuable than imitation.

Frequently Asked Questions

Are YouTube tags visible?

No. Tags are part of a video's metadata and aren't normally shown to viewers.

Are hashtags visible?

Yes. Hashtags can appear above a video's title or in its description.

Should I use both tags and hashtags?

Yes, as long as they're relevant to your content.

Can hashtags replace tags?

No. They serve different purposes and shouldn't be treated as alternatives.

What's more important than both?

Creating videos that people genuinely want to watch. Helpful content, strong titles and engaging thumbnails usually have a much greater impact than metadata alone.

Final Thoughts

Although YouTube tags and hashtags are often mentioned together, they solve different problems.

Tags quietly help describe your video's topic behind the scenes, while hashtags give viewers another way to discover related content. Neither is a shortcut to success, but both can support a well-planned publishing strategy when used thoughtfully.

The best approach is to create useful videos first, then use accurate titles, descriptions, tags and hashtags to help people find them.
