Clicking on this brings up a whole host of different search options that allow you to restrict your search and make it more relevant. I won’t go over what all of these do - Google will happily tell you - but I was particularly interested in the second from the bottom - Wonder Wheel.
When I searched for “renewable energy” it brought up a whole host of related topics, as the example below demonstrates.
When I clicked on one of the related topics - “types of renewable energy” it brought up the associated Wonder Wheel and the search results on the right changed to reflect the refined search topic – see below.
That is a simple explanation of how it works from a user's point of view. But how does Google select related topics? I can't find out. I must have read every blog and Google file available on the Wonder Wheel and no one wants to tell me!
I assume that if the wheel is automated by Google then the related content must be related to what people have previously searched for in the same Google session but I could be completely wrong.
If this is the case then surely this has a huge commercial benefit to people trying to launch new products, sites or even benchmark competition. Can it be used to generate related keywords to focus optimisation on?
Do you know? Can anybody tell me?
