The relevance of Impressions in SEO

I believe that I am in a unique situation with my efforts of SEO. My observations on what an Impression means is not "clouded" with queries about what most Internet users are searching for.

A case in point

My page on Judith Cockayne was getting Impressions for no other apparent reasons than it had an uncensored occurance of the name Raymond and Belchamp Walter. This was in contrast to my page on William Stern which I had censored the name Raymond.
