The star rating in the Seller Profile page is part of a test that we are currently conducting. It is an accumulated rating from buyers who rated their sellers.
How does the buyer rate the seller?
We have identified a selected number of sellers who marked their ads as sold, and asked them if they want to participate in this test. All those who are willing were asked if they want to be rated by their buyer.
By participating, these selected sellers have forwarded their buyers' information which OLX.ph uses specifically to get in touch only, in order to formally request a rating on behalf of sellers.
