To manage your sitemap, on your Nilead admin, open the Quick Menu and search for Sitemap.
By default, the sitemap is automatically generated for you. Simply enable the Page you would like to include in the sitemap and customize the Change frequency and Priority. Your site map will be automatically updated every 4h.
If you want complete control over your sitemap, you can upload your own sitemap file.
NOTE If you selected a custom sitemap file then the auto-generation will be skipped until you de-select the custom sitemap.
