Question about product reviews and Q&As on PLPs.

We're soon going to update our product listing pages. Currently we have all reviews and Q&As on the PLP, but to help with speed issues, and also because we're going to let customers add photos, we're moving them to their own pages, with 5-10 still on PLP, then "read more" link.

What is best practice? Just a relevant meta title, eg Reviews of [product name], Questions about [product name], or a canonical to PLP, or noindex, or something else?

Additional: Developer has just suggested: We could look to noindex/nofollow these pages, but put the rich snippet data on the PDP so it can appear in the SERPs.

Is this OK?

Sorry, meant PDP, product detail page!

I keep mixing those up, which is very annoying and confusing!
