Hi Jim,

well the video indeed covers almost every best practice that is essential.
Take care: the XML is always for search engines and must be managed using the robots.txt file, indeed the component does this automatically. The HTML sitemap is for users that visit the website. So publishing a link to the XML sitemap in the frontend of the website is never done and makes no sense.
The module that comes bundled is to show an HTML sitemap on the website positioned as a Joomla module that in some cases may be useful, such as having a navigation footer.
Best regards
John
