We wanted to make it a bit easier, so we put together this handy set of tips about seo, google-search, favicon, to guide you along the way. Read the discuss below, we share some tips to fix the issue about Google search does not display my favicons.Problem :

I have some favicon problems with Google search. I noticed that two of my webpages are displayed in Google search, but there are no favicons next to the link in the Google search listing, like this:

I have checked that when I view a webpage's favicon with this URL, it shows the right favicon but not in Google search: https://www.google.com/s2/favicons?domain=example.com

I have used same favicon tags than other webpages, and next to the other webpages Google search shows their favicons.

These are the favicon tags I'm using:

<link rel="apple-touch-icon" sizes="180x180" href="apple-touch-icon.png">
<link rel="icon" type="image/png" sizes="32x32" href="favicon-32x32.png">
<link rel="icon" type="image/png" sizes="16x16" href="favicon-16x16.png">
<link rel="manifest" href="site.webmanifest">
<link rel="mask-icon" href="safari-pinned-tab.svg" color="#5bbad5">
<link rel="shortcut icon" href="favicon.ico">
<meta name="msapplication-TileColor" content="#2d89ef">
<meta name="msapplication-TileImage" content="mstile-150x150.png">
<meta name="theme-color" content="#382d57">
<meta name="msapplication-config" content="browserconfig.xml" />

I used an online site to generate the above.

Solution :

The icons sizes you specified contradict Google:

Your favicon must be a multiple of 48px square, for example: 48x48px,
96x96px, 144x144px and so on. SVG files don't have a specific size.
Any valid favicon format is supported. Google will rescale your image
to 16x16px for use in search results, so make sure that it looks good
at that resolution. Caution: Don't provide a 16x16px favicon.

Use dimensions in multiples of 48x48.

If the issue about seo, google-search, favicon, is resolved, there’s a good chance that your content will get indexed and you’ll start to show up in Google search results. This means a greater chance to drive organic search traffic to your site.
