Mobile SEO and Desktop SEO are two different approaches to optimizing a website for search engine rankings. Mobile SEO is focused on improving visibility of a website in mobile search results, while Desktop SEO focuses on improving visibility in desktop search results. Generally speaking, the techniques used for both are similar, but there are certain key differences that should be taken into account when optimizing for either platform. For example, page speed is an important factor for Mobile SEO as it impacts user experience, whereas it has less importance in Desktop SEO. Additionally, you should consider page layout and layout options to ensure website content renders correctly on different devices.
