Site name is not displayed by Google + Schema.org: ‘alternateName’ is missing

Duplicate of https://github.com/sybrew/the-seo-framework/issues/663. Let’s continue there.

You did have a support question in this:

Also, any other ideas or bugs that can prevent to Google accept Site name?

I checked all my sites for this behavior, and the major difference between those that did have the name and those that displayed the URL was this: The ones with a name had the title in the logo as text.

I do not think it has anything to do with structured data.

So, you need to put the site name in the title of the site. Currently, it’s only an image. I recommend wrapping the image in a <h1> element (you may have multiple <h1> elements).

So, wrap the figure in an <h1> element, and add a span with ID site-title next to the image:

<h1>
   <figure>
      <a href="/"><img><span id="site-title" aria-hidden="true">Site Name Here</a></a>
   </figure>
</h1>

Then, hide the text using this CSS:

#site-title { 
    border: 0;
    clip: rect(0 0 0 0);
    height: 1px;
    margin: -1px;
    overflow: hidden;
    padding: 0;
    position: absolute;
    width: 1px;
}

You can also do a simple display: none;, but with the CSS above, the text is still selectable.

I also recommend instead using the fully qualified URL to the homepage instead of using "/".

I did exactly what you advised me to do. I’ll let you know as soon as I see any changes. Thanks a lot!
