In late February 2016 Google elected to remove ads from the right hand side of the page to open up space for it’s knowledge graph (a way to provide more relevant information to users within the search results pages). It seems that showing ads in this space is now also being tested.
Above is a screenshot from Google after searching the term “Dylon Works”.
As you can see above, Google has included within the right hand side of the search results page a sponsored listing for a product with a similar name to the property listing. This seems to be different to the shopping ads that can sometimes appear on the results pages as only a single listing is present. It seems like the testing is relatively uncommon as I have not been able to replicate this again for the same or similar searches.
Is there potential for a widespread sponsored knowledge graph rollout? My guess would be probably.
