Is this good article readability? Yoast says this.

Should I be concerned?

Please help. Thanks.

Keep it green as much as possible. You can use the Hemmingway app to improve them

It's hard to tell without seeing the article. Think of sentence length and style of voice as various types of tools in your writing arsenal. Creating articles that readers enjoy requires the right mix.

I think an article containing 40% total passive voice can lead to unnecessary confusion. However, without reading it, it is hard to tell. The 31% of sentences containing more than 20 vs 24.9% seem negligible to me. If it reads well, it reads well.
