Mobile dictates page length
Moving forward, site design is seeing a change from the past when pages were limited in length only to have a lot of added navigation buttons or menu options. The market share for mobile has pushed design to include longer scrolling pages. These may even include many of the pages broken into sections on a single page that in the past would have been broken up and only accessible by menu options. Since scrolling is easier on mobile devices and the amount of information that can be relevant to SEO can be increased on a home or landing page it can have a great positive impact. Just make sure the hosting on an extended page or “one-page” design is up to the task. Loading a page quickly positively affects SEO and the user experience, and it is important to have good hardware and software on the back end serving your page.
