In fact SEO plugins nowadays have become Swiss Army Knives that end up bothering the average user (and not so average) rather than helping. I am an SEO expert and consultant for clients. In these years of work I've seen many clients "optimize" their articles in meaningless ways. Just because they followed the rules of the plugins. I also notice how many content products have their creativity limited when trying to make the plugin "SEO score" all positive. SEO plugins are tools that may be useful for more experienced SEO users, within an established overall strategy, but end up disrupting users who just want to write.
