How to show customized website logo in safari "often visited"

Question

When I tap onto the address bar in safari I have a section "often visited" (german:häufig besucht) where the logos of my often visited websites are shown. However some of them, also my own websites, are shown with a standard icon. I will show the users of my website a customized icon. What do I have to do?

Here is an example (red marked):

Answer 1

The way this is done is through a link tag in the head of your HTML document.

For example, on that ARD website they use:

<link href="/ARD-144.png" rel="apple-touch-icon">

Which seems to be the image that is being displayed. Just replace the image with the one you want.
