I visited both Google and Gmail just now, and noticed that the favicons for these sites have changed, to a blue letter g. See for yourself, and be sure to refresh the page.

It would be interesting to know the story behind this. And how this seemingly small change will affect Google’s bottom line. What is the marketing department at Google expecting from this? :D

Can tweaking your site’s favicon increase traffic, or make your site more successful?
