Nobody pays to be listed or for their position. Listings are not assessed by Vultax; each profile says which pages its details come from. See them all on the map, or add a product for free.
Every profile is built from the product's own pages, and Vultax keeps a dated copy of each one. How the directory is made. Companies already listed can manage their profile.
