Best practices from 2014 still circulate as gospel
You do not need 500 characters of the same word with spaces shuffled. You do need the phrase a viewer would type if the title were missing.
Ignore anyone selling “tags for views copy and paste.” Views come from packaging and watch time. Tags help YouTube know the topic.

Do and don’t

- ●Do: series or niche labels (“sourdough beginner”).
- ●Don’t: other channels’ names as tags.
- ●Don’t: music tracks you do not have rights to, hoping for steals.
- ●Don’t: the same 30 tags on every upload.

Frequently asked questions
Are YouTube tags dead?
No. They are weaker than title and thumbnail, still worth filling correctly.
How many tags is best?
As many relevant ones as fit in 500 characters. Stop when you start repeating.
Can I copy tags from a competitor?
You can read them for language. Copying a dump that includes their brand and unrelated trends is how you confuse the classifier.
