Now, this is fun! And with a multiplicity of uses for all of us, whether seeking keywords, or wanting to brainstorm, research new ideas, products and so on.
The Google Wonder Wheel is a new option that Google are playing around with and you can too. Go to Google.com, and type in your keywords to the search box. Once the results come up, look to the top left and click on Show Options.
This will give you a host of new features, and in the left hand column near the bottom is Wonder Wheel.
The keywords you have entered will appear in a circle with related terms around that. You can click forever, exploring further depths, alternatives, and constantly generating new mindmaps from the Google search results.
It is a fab toy, and is well worth a play.
