Useless – doesn’t analyse

I tested this plugin’s analysis and it failed completely. As an example, I used “eco-friendly website” as a keyword in a draft and even a private published post and it kept saying that none of my keywords exist in H2, even though the second H2 heading is “What is green, eco-friendly website hosting?”. No matter how many times I refreshed the analysis or saved the page. Maybe it doesn’t like blocks in post text. Too bad since WordPress is pretty much a pile of blocks.
