Yoast SEO 3.3 has many new features. The most important improvement is the new content analysis: Yoast SEO checks both the readability and the SEO-friendliness of your articles.
If you hit the content tab, you will find 6 brand new content checks. These checks will help you write more readable texts. The plugin checks sentence length, paragraph length and your use of subheadings amongst many other essential SEO features.
Congrats to Team Yoast – ‘Yoast SEO’ is arguably the best SEO plugin there is!
