Our company ran a site audit on a very basic one-page website and is receiving this waing.
"Normally, a webpage can be accessed with or without adding www.to its domain name. If you haven't specified which version should be prioritized, search engines will crawl both versions, and the link juice will be split between them. Therefore, none of your page versions will get high positions in search results."
I know very little on this topic but want to know what I can do to the HTML so the "Link Juice" is not spread between www. and the domain name and so the message will not appear anymore. Do I need to add a robots.txt file to the root directory?
Site Structure
index.html
/images folder
Possibly relevant head info?
