Directory Listing Best Practices
Why should directory listings be created as sub-pages instead of a single page? #
Listing a lot of people in a single directory list or multiple directory lists can cause extended loading issues due to the number of people requested, along with usability issues, as discovering people in this way can be difficult.
Why is duplicate people in different directory listings discouraged? #
Listing someone in multiple places can have a negative impact on how search engines crawl your websites and in some cases lower your rankings in places like Google and other search engines.
