Please check your implementation of the Flesch-Kincaid readability score. The plugin is reporting a score of 8 for my text while other online resources report over 40. The number reported by the plugin doesn’t even match an expected FK grade level.
I’m hoping that we will be able to set our own acceptable FK minimum. A site I’m working on now, as an example, is a technical site. I fully expect the audience to be over the age of 19. I don’t want my SEO to flag a problem if the site can’t be read by a 12 year old.
