YouTube Shorts SEO: titles, descriptions, tags and hashtags

A Short can find an audience two ways. The Shorts feed behaves much like TikTok: watch behaviour dominates and text metadata is a minor input. YouTube search and suggested video behave like the rest of YouTube, where the title and description carry real weight. Most advice about Shorts only describes the first route, which is why so many creators treat metadata as an afterthought and then wonder why their Shorts stop earning views the week they are published.

The title

Write the title as the phrase a person would type if they wanted this exact video. Not a hook, not a caption. Those belong on the video itself. A title that reads as a search phrase can keep pulling views from search for months after the feed has moved on.

• Front-load the subject. Truncation on mobile is aggressive.
• Do not spend title space on hashtags. They display above the title anyway when placed in the description.
• Avoid all-caps and bracketed filler. Neither helps ranking, and both read as low-effort.

The description

The first line or two is the part that matters to both people and YouTube's classifier. Say what the video shows, in ordinary language, before links, credits, or boilerplate. If you have a related long-form video, this is the sensible place to link to it, because Shorts viewers who go looking for more are the highest-intent audience you have.

Hashtags: three, in the description

YouTube shows up to three hashtags from the description beside the video title. If a video carries more than 60 hashtags, YouTube ignores every one of them, but the more useful fact is the first one: only three are ever shown, so three relevant ones is the whole strategy.

The #shorts tag is no longer what makes a video a Short. YouTube determines that from aspect ratio and length. Including it is harmless, but it uses one of your three visible slots for a label the platform already knows.

Tags

Tags are the hidden keyword field, capped at 500 characters. YouTube has been clear that they play a minimal role in discovery, with one genuine exception: they help when your topic involves a name, acronym, or spelling that is commonly got wrong. Use them for disambiguation, not for coverage, and do not expect them to move a video on their own.

What actually decides a Short's reach

1. 1Whether people watch it rather than swipe. Nothing in the metadata rescues a video that loses viewers in the first second.
2. 2Whether they watch it more than once. Loops count, and Shorts are short enough that a good one gets rewatched.
3. 3Whether the topic is one YouTube can confidently classify. This is where the title and description earn their place.

The metadata does not make a bad Short succeed. It decides how long a good one keeps working.
