Depends what you mean. If you build a decent 10+ page site with on-target, relevant target on a related domain name and then get a few incoming links, you should be able to start to build up some "free" traffic from the search engines. But it's a bit more involved than "use good keywords" - you actually have to plan out a site that makes sense, in terms of coverage of the topic, main pages, navigation structure, page titles and so forth.
