How fast are the alerts, really?
Every Facebook Marketplace alert tool claims to be fast, so here's the honest version. JDMarket checks your searches every minute and sends the alert about a second after it detects a matching listing. But no tool is truly “instant”, because Facebook itself takes several minutes to approve and index a new listing before any tool can see it.
The short answer
- JDMarket checks your searches every minute (on every-minute watches) 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.

What “fast” actually means
Speed has two parts: how often the tool checks, and how long Facebook takes to make a listing visible. JDMarket controls the first — every-minute checks and a ~1-second send after detection — but the second is Facebook's, and it caps how fast any tool can possibly be.
Why “instant” is a red flag
If a tool promises “instant” alerts, it's glossing over Facebook's approval delay. We'd rather tell you the truth: we're near-real-time once a listing is live, and that's usually enough to be the first message.
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?+
No tool's are. JDMarket checks every minute and sends the alert about a second after it detects a match, but Facebook's own ~7-minute listing approval applies to every Marketplace alert tool. We say “near real time”, not “instant”, on purpose.
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.
