The odds of actually achieving a job via a nameless entry in the Skills for Sale section of a jobs website or print classifieds are slim, but not unknown. However such listings do provide a great resource, noting areas of opportunity, companies that are hiring, and of business language to use in your own search materials. Scan the type of ads in each listing with a Goldilocks eye: nothing near your field is too cold; a million similar ads makes the competition too hot. On the fringe is just right.
