Yoast SEO ‑ Store optimization

I've had the app installed for just over two weeks. Since installing the app, my traffic from Search has dropped 50%. The jury is still out, but this does not bode well. I also think the app leaves a tremendous number of things off the table. If I run a free site audit from another service, all kinds of fixable stuff appears that I would have no idea about if I was relying solely on the Yoast app. It seems that all this app really does is act like a kind of Grammarly for SEO, but it asserts itself (from a technical standpoint and a marketing standpoint) as the be-all-end-all SEO solution—and this is problematic because I'm guessing it doesn't exactly play nice with the other SEO apps you might need to actually have a complete SEO game. After committing to this app and spending a lot of hours on it, I'm finding it very dispiriting. And that's really the worst part.
