Google wants to provide users with the best results as quickly as possible. Search engine optimization is a way to show Google that your content is suited for the topic at hand and relevant to the user. Typically, sites that aren’t optimized fall lower in search results, and sites that have been optimized appear higher in search engine results pages (SERPs).
Optimization can take on many forms, but generally, tactics are designed to cater to Google’s algorithm. Front-end SEO includes everything within your site that is visible to both website users and search engines. These are the on-page elements that can be optimized for Google, like content, titles, and photo descriptions.
On the other hand, technical SEO is less about website users and more about Google. It focuses on the systems that allow your website to communicate with search engines, like a website’s coding. Technically optimizing your site ensures Google can understand your content, index it, and show it in search results.
