Hello,
Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for any inconvenience this issue may have caused you.
I’ve checked the category pages, and they seem to be empty.
By default, Rank Math sets to noindex your empty category and tag archives. However, to disable that feature, head over to your WordPress dashboard > Rank Math > Titles & Meta > Global Meta > Noindex Empty Category and Tag Archives.
Here’s a link for more information:

I have already disabled that, and the links you have shared are already indexed.
Hope that helps.
Thank you.
Check the planters one. That one isn’t empty along with the other ones. It was also indexed and ranking. It’s set to noindex now and lost all the traffic .
Seems that my planter category page decided to change status, but this one: https://the-laser-boutique.com/product-category/gardening/bird-houses/ hasn’t,
Hello,
Even if the categories are showing the products in the front end, if you check the Product Categories section in the backend, the product count is zero for the affected categories:

That’s why they are set to Noindex. If you have assigned the products to their child categories, even if they show those products in the front end, they are not directly assigned to them as per WooCommerce and WordPress’ behavior and our plugin will also see the same and will set them to Noindex.
In this case, you should either assign the products directly to those categories or disable the Noindex Empty Category and Tag Archives option in WP Dashboard > Rank Math > Titles & Meta > Global Meta.
Hope that helps. Let us know if you need any other assistance.
