Re: Adsense Section Targeting
Just to add... you only need to use the section targeting that Google provide if your site is not showing relevant Adsense. Looking at your site this morning, and presuming you haven't added the code yet, there doesn't appear to be any reason or benefit for you to do this on any of the pages I have looked at. I took a random selection of about 7 pages. Your adsense relevancy is very good to be honest. The section targeting is rarely used and those that use it often have poor content or mixed content that confuses Google into showing irrelevant ads.
Don't aim for success if you want it; just do what you love and believe in, and it will come naturally.
