I’m finally able to work on optimizing my Shopify store - currently focused on my reviews, and I think I have an issue

I sell one of a kind handmade sun catchers, meaning each catcher has its own listing, and when it sells, that’s it, it’s now sold out. Still listed, but it says “inquire about reorder”

Here’s the predicament: when I receive product reviews, you know, the kind approved for Google - they’re only on sold out products.

Another issue is that half of my reviews overall are coming from commissions that were not processed through my store, so they are considered “site reviews” ie not approved for Google.

I don’t know anything about Google listings, and I’m only now trying to optimize my store.

I just switched to yotpo from judgeme as it has a $15/mo subscription for reviews that fits my small business and they’re an approved Google partner. but now I’m wondering, since the only reviews I can show are for sold out items, is that impacting my store rating, reputation, SEO, etc negatively?
