Google has announced that they are now also supporting site names for subdomains on mobile devices. This was after it was added to the domain level for desktop searches last month.
Site names in search results was initially introduced on October 2022, which were only for the domain level and for mobile search results for English, French, German, and Japanese.
What Are Site Names?
Site name is the name of the site that Google determines and shows in the search results. It looks like this:
According to the search documentation on site names, Google uses a number of different sources to automatically determine the site name. It takes into account both the content of a site and references to it that appear on the web. The goal of the site name is to best represent and describe the source of each result.
These following sources from a site’s homepage are used by Google to determine the site name:
Website structure data
<title>
elements<h1>
elementsog:site_name
Website owners can indicate their preferred site name by adding the website structure data. The site name documentation shows guidelines on how to set this up for your site.
Google has also provided some common issues encountered with site names in the search results:
Last month, Google posted a webform where site owners can provide feedback about their site names and issues encountered in the search results. This is after a number of people have reported that Google is displaying the wrong site name.
While a number of people have seen improvements and changes after Google has rolled out a change that aimed to resolve the issue, there are still some that reported the issue still existed. To deal with this and any issues encountered with site names, Google has opened up a forum where questions and issues encountered can be reported to the team. This can be accessed here.
