Hi there @rrr_ruby!
I did some checking into this query for you and was able to find some helpful info in this previous post in the Community.
Check it out to see how you can add a no-follow tag to any link you're using!
There's further info here on this external, third-party resource on no-follow tags that you can check out too.
Check it out and see if you can put this in place for the links you're using for your own store.
Could you tell me a bit more about your business and what else you need to work on?
Thanks for your email.
We specifically want to add a no-follow link to the footer item, (and mega menu item), sorry maybe I wasn't as clear as I could have been... here are screenshots of the back-end which doesn't seem to allow it, hence my question.
I have added screenshots.
I notice that it is possible here on the shopify community website - see attached.
(It's a similar story on the mega menu but if the footer can be resolved, then the same may be applicable to the mega menu).
Many thanks Shopify community!
