I don't think people would call this "best optimization". Because Optimization is a step in complete SEO process.
You'll start with Onpage Optimization which contain 2 steps : Optimize keyword, optimize content.
Then If you feel something not right on Off-Page, you'll also need to Optimize Off-page: In this step, you have to check every of your backlank again (anchor type, keyword type, backlink type, spam backlink,....)
