Yoast recommendations would be good for onpage optimization. But you will still need to perform other tasks like researching your keyword, etc, that would be the core of the entire SEO thing.
Once a proper keyword is established, then you will know what type of links to build. HQ links are what it takes to rank these days. Yoast will not be able to advice you further on these type of links - you'll need to at least use metric tools as the first vetting to find good quality ones.

As you can see ''best watches'' is not related to the main ''shoes'' niche
