My main website is about southwestern gardening. I added adsense ads about 3 years ago. At first the revenue was very small.
Right now I am
very pleased with adsense revenue.
What did I do to turn things around? I added good original content to my web pages. I wrote numerous gardening articles to article directories. Answered lots of questions at yahoo answers. Sign ups to my gardening newsletter went up by almost 75%.
I am not familiar with smartpricing maybe you can give us more information on the subject?
