Metaphor? Simile?

Person is to penis as website is to SEO.  On the otherhand there’s two gentlemen arguing super loud at the bus stop. 
But back to what I started out with…  If I looked into getting some over priced SEO service would that me average but self-conscious due to an unrealistic view of website traffic?  Then again would I really want to encourage spam on my personal blog by supporting an industry that spams?  How can “spams” not be prepopulaytd in the dictionary.  Preposterous is.
