Enable Search-Friendly URLs
For your sitemap to include search-friendly URLs, you must enable them before creating your sitemap. Salesforce recommends that you enable search friendly URLs for your Production instance but not your Staging instance, because it makes it difficult to add content asset links based on URLs you want to link to.
Note: Before enabling search-friendly URLs, you must
assign an alias to your site, otherwise, URLs don't appear correctly in
your storefront.
Note: The SEO Support module functionality is
deprecated.
