Do YouTube tags matter? What YouTube itself says

Tags barely matter, and YouTube says so itself. Here is what tags are still good for, what deserves your time instead, and a two-minute tag routine.

What does YouTube itself say about tags?

YouTube is unusually direct about this. Its Help page on tags says tags are descriptive keywords that help viewers find your content, and then adds that your title, thumbnail and description are more important pieces of metadata for discovery.

The same page says tags can be useful if the content of your video is commonly misspelled, and otherwise play a minimal role in your video's discovery. YouTube's page on editing video settings repeats this word for word, and describes the Tags field as a place to "help correct search mistakes".

The performance FAQ is even shorter. To the question "How important are tags?", YouTube answers: not important. Tags are primarily used to help correct common spelling mistakes, and its own example is YouTube versus U Tube versus You-tube.

So when a course or a tool promises that the right 30 tags will make your video rank, it is promising something YouTube says is not how its system works.

Then why do people still say tags matter?

Partly habit, and partly because tags are not zero. YouTube's page on how search works lists the title, tags, description and video content among the many factors it uses to judge how relevant a video is to a search. So tags are one small input, next to much bigger ones like whether people who search actually watch your video.

Old advice also tends to outlive the system it was written for, and long tag lists look like effort, which makes them feel useful. The honest summary is: tags can help YouTube with an unusual spelling, and that is about it.

What matters more than tags?

The three things YouTube names: your title, your thumbnail and your description. These are what viewers actually see, and YouTube says they help viewers decide which videos to watch.

A clear title that names the topic in your viewer's words does more for search than any tag list. A description whose first lines repeat your 1 to 2 main words, as YouTube's description tips suggest, does the rest. If you have twenty minutes for packaging, give fifteen to the title and thumbnail, four to the description and one or two to tags. The guides on writing YouTube titles and description templates show where that time goes.

Beyond packaging, the video itself decides how far it travels. YouTube's recommendations learn from what viewers watch, how much of it they watch and whether they were satisfied. No tag can fix a video people leave after ten seconds.

How many tags should you use, and which ones?

A handful of accurate ones. YouTube does not recommend a number, so this is our practical advice: five to ten tags is plenty for most videos, and fewer is fine. Every tag should be true for this exact video.

The tags most likely to help are the ones that match YouTube's own reason for having them, which is spelling:

• Spelling variants of your topic: "puran poli" and "puranpoli", "chole bhature" and "chhole bhature", "Kolhapur" and "Kolhapuri".
• The other script your viewers type in. If your title is in English letters, add the Devanagari form, like "पुरणपोळी", and the other way round. This is our tip, not YouTube's. It is not a misspelling, just another way your viewers write the word.
• Your main topic in plain words, the same 1 to 2 words you used in the title and description.
• Your channel name, especially if people misspell it.

The weak list is mostly words that describe a million other videos, plus a few that are not true for this one, like a city it was not filmed in. The better list is short, specific and covers the spellings a real viewer might type. The channel name in the example is invented.

What is the difference between hashtags and tags?

They sound alike but do different jobs. Hashtags are for viewers. Tags are for YouTube's spelling help.

One more difference: a hashtag that is unrelated or misleading can get a video removed. A loose tag is more likely to be simply useless. Neither is worth the risk.
