A favicon helps your website appear more professional and credible. Although it’s a small part of a website, the inclusion of a favicon shows attention to detail and also gives the impression of a more complete site.
A favicon also provides an opportunity to further reinforce your brand.
A favicon makes a website more user friendly. With more and more people using tabbed browsers, the fact that your favicon will show up in the tab next to the page title makes it even more important for brand reinforcement and recognition.
