Why wouldn't that be for everyone? Some words will get a lot of traffic, some will get a lot of sales. It takes a LONG time to optimize a site for the search engines, but setting up PPC takes minutes. So its better to figure out what keywords are getting sales, not just traffic, as quickly as you can. Then focus your SEO efforts on those words.
