Pros: fixes title tags, meta descriptions, alt text, and schema markup without needing to alter backend code. Of course there are other errors that need fixing but these are among the most time consuming of seo fixes to take care of.
- ask yourself would you ever fix them yourself or trust anyone to do it manually AND consistently lol

Cons: Javascript snippet fixing works. Another Appsumo SEO app, Nytro SEO uses the same tech. Website speed will slow a bit since the js with fixes needs to rendered.
Does Google read the edits ? yes all of it on larger sites? unclear... js rendering costs for robots to execute the literature says about 9X more processing but Google probaby does it faster. Still Google could change their mind someday since they have energy issues. Who knows?

DO AI BOTS render JS for SEO. As far as I know the answer is NO. Please correct me if I am misinformed on this. Hey would I rather have something that works now since being in the top 3 is all that matters to stay in business? YES.

Is the slowdown worth it ! For Nytro it was . Looking at their app . These guys are good.I'd be surprised if their rendering server code is slow. Is inline fixing better? YES don't complain go do it yourself haha .

Overall incredible value. Easily 5 tacos. Just be aware the asterisks....
