问题
I do have a Favicon on my website, and it shows up on the address bar.
But I was curious how to get these big icons when you bookmark a page. Is a different thing or did I do the favicon wrong?
As you can see, Behance, LinkedIn, and others have a big icon when bookmarked and my website on the left has none.
<link rel="icon" href="icons/favicon.ico">

You need different icons:
- Safari on Mac OS Yosemite (apparently, what you are using): it takes the Apple Touch icon. At least, make sure to create a 180x180 icon.
- Chrome: since a few versions, Chrome takes the Open Graph image (the same icon you use to indicate to Facebook which image to use when a visitor shares your page). Note that Chrome might take something else if it can't find the OG image. Rules are not clear.
- Some other browsers: apparently, some browsers, such as Firefox, have default icons for famous web sites but generate miniatures for the other bookmarks. I can't be 100% sure of this, but I couldn't find any documentation about that. This is just guess work.
