The numbers match the steps below.
  1. In Posts, select Boost on a published post (or Ads → Boost a post). Choose Which publication to boost.
  2. Choose who pays: Through JustCaster (one invoice: ad budget + fee + VAT, JustCaster runs the ad) or My own … ad account (the network charges your card, no JustCaster fee). Only the ways open to your account are shown.
  3. Choose the goal (Reach more people — the default — or More engagement), the total budget, the duration and the ages.
  4. Choose who sees it: whole countries (up to 10), or people around a region or city: pick Region, City or Postal code (only the kinds the network offers), search it and choose it in the list. Around a city you can add 5 to 80 km on Facebook / Instagram / Threads and YouTube; Meta then shows the place and its forecast.
  5. Select Pay … and boost: the payment page opens; once paid, the boost goes to the network, which reviews it (often within an hour). With your own ad account, select Boost: it is sent at once.

Follow your boosts

  • Ads → Boosts lists each boost with its status (Waiting for payment, In review at Meta, Running, Ended…), budget, spend, reach, engagement and clicks, read every hour.
  • Waiting for payment: Pay, I have paid (checks the payment), Cancel (cancels its invoice). Running: Stop.
  • Paid through JustCaster: what the network did not spend comes back as ad credit, used first on your next boost. An unpaid boost is cancelled after 7 days.
  • A team member’s boost waits for the owner to pay its invoice (Billing → Invoices).
