The website URL is
http://example.com but some pages have been redirected to
http://example.com/, the version of the URL with the trailing slash. Should I change all redirects to the non-trailing-slash URL?
Homepage: Google has stated that the homepage doesnt really matter if there is or isnt a trailing slash.
Directory: directories must have a trailing slash in the end.
File/Page: an html page or an file shouldn't have a trailing slash.
