As I understand it, the highest paying ads are closets to the top. Therefore, if my side bar is higher than my content block does that mean that my content block is paying less? My reason to ask is this, today I was paid more per click from my side bar clicks compared to my content block clicks. Does this mean that I should lower my side bar ads so that they are lower than my content block?
I dont think that is true. I received $1.++ per click for the ads at my comment section (which is located at the bottom). It all depends on the keyword of the ads. Certain keywords pay more per click.
