My main SEO concern now is ranking for the cities I teach in. According to Yoast SEO plugin, I need to have 400 words in a page to rank well for a certain cities. Is this really necessary? For example, for Woodbury violin lessons, Woodbury Violin Lessons | Violin Lessons | Pro Violin, and other city pages, do I need to have at least 400 words?
Like I said before, I will address website speed later with newsite.proviolin.com.
