I'm glad I decided to build out my own advertising program a couple of years ago. I've left Adsense in some less important positions I couldn't sell, and watched those steadily decline over the last two years. now I may just remove them completely and sell them as cheap up sells to existing advertisers. I'm doing well without Adsense.
There was a time when I knew small business owners and individuals that made enough to pay their rent or better with Adsense. Just as those same people have been squeezed out of the SERPs, they also have been squeezed out of Adsense.
