CPA Stats

I've heard people talk about mixing white hat methods with blackhat methods in order to make your stats appear less blackhat.

I'm using a CL method and so most people who go to the landing page, also go to the CPA page too.

Does anyone have any general guidelines for stats I should be trying to hit or else my account could appear suspicious?

I'm talking about Impressions, Leads, Clicks, Sales, etc.

Thanks a bunch

*knock knock knock* this thing on?
pweasee some advice?
