I'm noticing a pattern regarding Google's Knowledge Graph (KG) and I wonder if others are experiencing the same.
I want to add a custom text-based image to show up in the Knowledge Graph. Google provides the markup for logos in the knowledge graph, but when I add it to the Head section, then Fetch as Google using GWT, the logo still does not show.
The image that does show on the KG is from our Google Business Page (GBP). The image is an exterior view of our office, showing our door. If I remove this image from our GBP, refreshing the Search results yields another photo from our GBP. I tried uploading the Intended photo to our GBP, but still does not show. Interestingly, if I remove ALL of our photos except the Intended photo from GBP, refreshing the Search results displays a placeholder image, not my Intended one! Why is that?!
Question: Does Google only show specific types of images on their Knowledge Graph, ie logos or stock photos, but not text-based images? They are pretty clear about the ability to customize the schema markup, using any image URL you specify. Why won't it show my Intended photo?
