First of all, reviews are generally given for individual entities (a product, book, car, business).
1. Do these entities each have their own page? If yes, then you should assign reviews directly to those entities by adding the shortcodes to the entity page:
[site_reviews_summary assigned_to=post_id]
[site_reviews assigned_to=post_id schema=true]
[site_reviews_form assign_to=post_id]
This will automatically assign new reviews to the current entity page, and only show the rating summary and reviews assigned to the current entity page. Enabling the schema option will generate the JSON-LD schema that will be used by google search (when showing search results that link directly to your entity page).
2. If your entities do not have their own page or URL, then you can instead assign reviews to a Site Reviews category (however, in this case you should not enable the schema since your entities do not have a dedicated URL).
[site_reviews_summary category=iphone]
[site_reviews category=iphone]
[site_reviews_form category=iphone]
3. If you have thousands of products, then for performance reasons you should only be assigning to a page OR to a category, but not both. Using only one or the other will allow Site Reviews to cache the rating summary; if you use both, then Site Reviews will need to calculate the rating summary on each page load.
4. If you need to bulk assign existing reviews to existing entities, you can use the bulk edit tool:
