Similar to ALLI and now Hike SEO, ClickRank provides great AI SEO updates. I'm using this for my personal website so I can have it auto-optimize since I rarely make time to work my SEO magic on myself (LOL). It does a great job with schemas, even picking up on podcast episodes, and I can see it's implementing the changing. Yes, it's done through javascript and if you remove the script the changes will go away, this is no different than other plugins. I'm using it on a Ghost website and it's a challenge to get it to exclude pages since the folder structure is different than WordPress, but otherwise I'm super happy with what it can do.
