Google Adword/CPC & SEO Question?

[fatfinger563]

I wanted to make sure I'm using this service correctly:

I first put my article title/subject in the keyword generator: https://adwords.google.com/o/Targeting/E...earch.none

Then I chose the keywords w/ the highest CPC, and inserted those keywords into the article content.

This is what I did, however, the Google ads which appear on the side bar are different from my keywords, and they have less CPC (I checked the ad titles on the key word generator as well)

Are the generated Google ads supposed to different from the keywords I chose, or am I doing something wrong?

Thank You!
