The website footer refers to all elements at the bottom of a website. Here the user often finds information such as links, contact details, legal notices, social media integrations and other additional content. The footer area is mostly located below the fold - that is, at the very bottom. But generally, the information in the footer navigation varies depending on the design and requirements of the website.
For SEO, the footer navigation is important because it provides additional internal links to the web crawlers. By including important links in the footer, crawlers can better recognize and index all relevant pages of the website. If it is still present in the website, then the HTML sitemap can be placed here.
In the source code, the footer is often marked with HTML tags like #footer #!footer , and the links are usually created with #a ... #!a tags.
