Here’s the category page link: https://www.perfectmakeupmirrors.com/light-bulbs-and-parts.html I want it to appear in the site menu and be available to users. I just don’t want it crawled.Where in Magento can I do that?
You have to set the meta robots NOINDEX tag to your header. You have to use a module for this, because this is not a magento feature. I use this module.
You can use the design configuration to update the rule, See here for command https://en.wikipedia.org/wiki/Robots_exclusion_standard
You can install this free extension: https://github.com/TidycodeIT/magento2-meta-robots
