Here is a part of like my .htaccess file that makes no www and no ending /.
# Redirect www to non-www
RewriteCond %{HTTP_HOST} ^www\.gugquettex\.com [NC]
RewriteRule ^(.*)$ https://gugquettex.com/$1 [L,R=301]
# Redirect URLs with trailing slashes to non-trailing slashes
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)/$ /$1 [L,R=301]
#X E.
What that means is there is only one URL for each file except main gugquettex.com and that search engines will therefore rank me better. Be sure and replace "gugquettex" and "com" with your domain name and adjust any more that is needed. I got this from zzzcode.ai.
