We tried out a Google recommended system which is supposed to increase our advertising revenue, but it was at the expense of User Experience - so we have now reverted to our original site.
I get a bit frustrated with the Google organisation from time to time - especially as it is now my main source of income!,
Many sound-bites about how important the end user is and basically they have grown their business in the past by providing the user with good experience in the Search engine side of their business.
Practice what we preach may be a good mantra for the company as a whole!
