All pages have a “breadcrumb trail” at the top, for example: “You are here: Home > Catalyst > Ethylene oxide ”. The breadcrumb shows where the page currently displayed sits on shell.com. Each term in the breadcrumb is a link that allows you to access the parent pages of the current one and the shell.com homepage.
The sitemap can be accessed by clicking on “sitemap” in the footer that appears at the bottom every page. The sitemap gives you a hierarchical outline of the entire website and links to content pages and sections. It gives an overview of the first two levels. Clicking on the second level reveals the links to every page in that section.
