Effective use of Google Analytics and Adwords

I added Adwords Analytics to the source code of each page in the site to help track better performance of each page so I can see what the bounce rate is and which pages are being visited the most.
   I use Adwords for my main page and for Affiliate pages to help generate extra revenue. What is interesting is I can see stats for pages that my campaigns are not set for, which in return gives me more detail on what is happening on my site and how I can better optimize those pages that are attracting more visitors.
  Now for the Affiliates I use Googles Keyword suggestion tool and I filter out keywords that are forbidden to use for the companies I affiliate for. For example  this page: Affiliate Marketing Program Software. I did not use the company's name or software title for the page name or in title.
  After a day or two of running the adds Google gives me some more keyword suggestions that I filter through and pick for better conversions.
