Having not been so familiar with SEO and Readability, the YOAST SEO plugin is a godsend. It trains one to properly structure sentences and somehow guides you through each article you create. Without this plugin I’d still be relying on a lot of scattered and conflicting ideas. A definite no-brainer for beginners who are unsure of what plugins are essential. Although the free version is already more than enough, I can only imagine how good the paid one is.
