Speed, honestly

How fast are the alerts, really?

Every Facebook Marketplace alert tool claims to be fast, so here's the honest version. JDMarket sends instant alerts the moment a listing goes live — about a second after it detects a matching listing. The one caveat is Facebook itself, which takes several minutes to approve and index a new listing before any tool can see it.

The short answer

  • JDMarket sends instant alerts the moment a listing goes live — on instant watches it checks every minute and sends the alert about a second after it detects a match.
  • No alert tool is truly instant: Facebook's own listing approval/indexing typically adds around 7 minutes before any tool — including the priciest — can even see a new listing.
  • That means a fresh alert that reads “8 minutes ago” usually reflects Facebook's delay, not the tool being slow.
  • You can test any tool yourself: post a listing from your own Facebook account and time how long until the alert arrives.

01

What “fast” actually means

Speed has two parts: how fast the tool alerts once a listing is live, and how long Facebook takes to make a listing visible. JDMarket controls the first — instant alerts the moment a listing goes live, with a ~1-second send after detection — but the second is Facebook's, and it caps how fast any tool can possibly be.

02

Instant — with one honest caveat

We send instant alerts the moment a listing goes live, and that's usually enough to be the first message. The one honest caveat is Facebook's own approval delay: before any tool — including the priciest — can see a new listing, Facebook takes a few minutes to make it visible.

03

Test us yourself

Post a cheap item from your own Facebook account, start a watch that matches it, and time the alert. It's the most honest benchmark there is — and the one we'd run if we were shopping for an alert tool.

Questions

Are JDMarket's alerts instant?+

Yes — JDMarket sends instant alerts the moment a listing goes live, about a second after it detects a match. The one caveat is Facebook itself: its ~7-minute listing approval applies to every Marketplace alert tool before a new listing is visible.

Why did my alert say a listing was posted several minutes ago?+

That gap is almost always Facebook's listing-approval delay, not JDMarket being slow — Facebook often takes around 7 minutes to make a new listing visible before any tool can detect it.

How can I verify the speed?+

Post a listing from your own Facebook account, run a matching watch, and time the alert. That end-to-end test is the fairest way to compare any alert tool.
