I know that content ruins a website because of "Duplicate Content" and they won't earn much. However I was wondering. If made a xHTML and CSS layout and used it for several of my websites with "Unique Content" would there be any penalties? The layout will have unique graphics, and slight changes for each website. However the base of the code will basically be the same. Will this cause problems for SERPs, PR, Revenue, anything? Thanks, BlueEew.
