Not sure why, but of late quite a few tabs I've seen have been bereft of favicons (those little icons with the website's logo), replaced by a generic blank page icon. I keep thinking those tabs are showing broken pages, when that is far from the case.
It's really easy to add favicons these days, Wordpress has made it an in-built function for instance (so I added one to Sabotagereviews.com)
It might seem like a small thing but it's an easy way to add credibility to your website.
Favicons Build Brand Awareness We all know the importance of logos. It is what visually connects us to a company. What would McDonald’s be without the golden arches? Or Twitter without the little blue bird? Whether it is derived from your company’s logo or an entirely new visual representation, a favicon functions like a miniature logo. It helps internet users remember your brand.
