An important step in managing and promoting a YouTube
channel is to add the right channel keywords
Keywords can indeed help users to discover your YouTube channel when they perform searches on Google, YouTube, and other search engines.
Adding Channel Keywords on YouTube
The first and most important step is choosing keywords that specifically represent your channel and the type of content published.
Once you've selected your keywords, sign in to YouTube. Click your profile picture > Creator Studio
Type your keywords in the Channel Keywords
field, then click Save
You should separate your keywords with a space and use quotation marks when search terms are in the form of short phrases.
