Search rankings are boosted by the number of orders completed, % positive reviews & ratings, as well as endorsements. Whenever an order is marked complete on Science Exchange, the requester has the opportunity to leave a review. Another factor that influences search rankings is Endorsements, which can be left by anyone who has a Science Exchange account. NPS scores are also collected from requesters, which show up on your Storefront under Ratings.   To learn more, please see our blog post: How does Science Exchange rank service providers?
