Thomas McMahon brings up an interesting SERP for the term "hardware tool" at Google. After the first five organic results, Google suggests that he may want to see the top three results for the term "Commutator," and insert three such results before continuing with its "hardware tool" results. (Please contact me for a screenshot if you cannot duplicate the above results).
Since one of the definitions of a "commutator" essentially describes a piece of hardware used as a tool, could Google somehow have assigned semantic connectivity between the terms? I sure hope Orion sees this. I look forward to other ideas or perhaps even a correction if my thinking is flawed.
