Does the address of your Youtube account look like this or something similar?
Nobody can remember this address. You can not explain on the phone how to reach the site.
It doesn't have to be.
Striving for a high ranking in search engines for such a site is a lost effort. The rule will be that search engines will not list such pages at all.
It is advisable to register your own domain for the subpage on Youtube and then forward it to the subpage. This domain could be called johnssyoutube.yt, for example.
This increases the chances of your own YouTube account appearing in search engines.
There is much to be said for using a yt-Domain for your own Youtube account, because the memory of a yt-Domain is high due to the fact that yt is an abbreviation for Youtube.
Secura GmbH registers a yt-Domain for you and forwards you to your YouTube account.
