Today I was reviewing my Moz analytics and suddenly noticed 1,000 issues with pages without a meta description. I reviewed the list and learned it is 1,000 checkout pages. That's because my website has thousands of agency pages from which you can buy a product, and it reflects that difference on each version of the checkout.

So, I was thinking about no-indexing (but continuing to 'follow') these checkout pages, but wondering if it has any knock-on effects I may be unaware of?

Any assistance is much appreciated.
