I read that it makes changes in content in DOM, with a plugin you can apply it directly to WP. But what about a non-WP website in my case Umbraco CMS. Is there a good overview of suggested changes that I then easility apply myself. Or even better suggested changes are visible doing an API call and I can make a process myself to apply it to my website.

And without this making changes features are there other helpfull functionality that I might consider buying this tool for ?

I know the owner does not answer any question so if any othe Sumo user who has this tool has any insides please share.
