I think you must concentrate on every factor of SEO ....Do the best of all things such as on page optimization, get quality backlinks , unique content and much more ..... i think you must not wait for doing only one thing and must go for all .....because all that is a part of seo and cant get results on one. Whats the problem in doing total Seo ? Dont just don't concentrate on ranking in Yahoo only.
