Hello,
Sorry for the experience you had while using the plugin. We will try our level best to help you get to the bottom of this.
There are a few things you have to keep in mind when using any SEO plugin, not just Rank Math.
1. An SEO plugin alone cannot bring down or bring up the traffic in a day (or even a few days) unless incorrect Meta Tags are used by setting up the plugin improperly. That’s why we have a detailed tutorial on that:
https://rankmath.com/kb/how-to-setup/
2. All the SEO plugins add Meta tags for the search engines, which can be checked by viewing the source of a page. For instance, here:
view-source:https://rankmath.com/
Other popular plugins generate similar tags:

And with the Rank Math plugin, additional tags are added to a page so search engines can understand the content on a website better.
3. Google brings a new algorithmic update several times a month, and the chances are great that your website got hit by that.
We have a full guide on that: https://rankmath.com/blog/google-algorithm-update-recovery/
In the PRO version of the plugin, you can even see if the drop in traffic correlates to an algorithm update. Here’s how:

Let us know how it goes. Looking forward to helping you.
Thank you.
