No. A demand you open is never published on the open web or indexed by search engines — it is listed only inside a closed marketplace visible to signed-in, verified suppliers whose categories match yours.
Demands live on the Marketplace screen, and that screen is members-only: type the address without signing in and you simply land on the login page. Every request that loads demand content runs under your own session, so neither a non-member visitor nor a search-engine crawler can read your demand title, line items, budget or company name. No public listing page enumerating demands is ever created on marblemap.co.
Visibility is matched on the supplier side too: the Marketplace list shows published demands in your category, so relevant verified suppliers see your demand rather than the whole internet. Offers arrive sealed — no supplier sees a rival's offer, price, or even how many offers exist, and buyers cannot see each other.
You stay in control: while the demand sits in Draft nobody receives it, and only publishing exposes it to matching suppliers. Change your mind later and Remove from marketplace takes it off the list.
