Utility pages are links often placed at the top of a site, and footer pages are links often placed at the bottom of a site. For example, on Slickplan.com, utility pages could be about us, login, sign up, etc. and footer pages could be terms & conditions or media kit.
To add utility pages, expand the utility area above your home cell and click on add utility page. To add footer pages, on the bottom of your sitemap expand the footer area and click on add footer page.
