Welcome to WebmasterWorld Guest from 220.127.116.11
You are not locked into doing anything they suggest, they are JUST suggestions. You can probably bounce ideas off them while you're talking.
Be sure and ask if there are any beta programs running that might benefit your site, and if there are, see if you can or want to try the beta.
My experience has been that they are genuinely concerned about helping you increase income (theirs increases too, of course) in a way that also enhances a site visitors experience.
After my second talk with the team last month, I was asked to particapte in a conference call with members of another department. I agreed. The sole purpose was for them to get my feedback and experience with AdSense. They asked a lot of questions. I was impressed that they took so much time to speak with me and get my opinions, suggestions, etc.
They require that items discussed remain confidential.
Interestingly, I was told that they could provide me with additional suggestions if I wanted them, but that they thought my site had really good content and unless asked to do so didn't want to suggest something which might overshadow the content.
