Yoast SEO 18.0

Yoast SEO 18.0 is out now! This release contains a number of bug fixes and a couple of enhancements. We've enhanced schema presentation for non-alphanumeric languages and made several improvements in both the SEO and readability analysis of the Japanese language. Read more about what's new in Yoast SEO 18.0 in our release post in English or our release post in Spanish!
