This increases your company brand recognition among your frequent users. It also improves your website usability and user experience. When searching on the internet, most users have many tabs opened in their browsers. As the number of tabs increase, your website name hides. Exactly in this moment, favicon helps users to identify your website and quickly switch to the tab they need.
