Listing syndication

When a listing entered in the MLS is copied out automatically to the big public sites: Zillow, Redfin, Realtor.com and the rest. Most listing services turn it on by default, but each portal can be switched separately, and each one picks up the listing and shows its details at a slightly different speed.

Part 1 of 4

Why a seller cares

Syndication is how one MLS entry reaches every portal. It is on by default, each site picks the listing up at its own pace, and a wrong detail in the MLS is copied everywhere before anybody notices.

Part 2 of 4

A simple example

Your listing enters the MLS at 9 a.m. It is on one portal by noon, another by evening, and a third the next morning, with a typo in the square footage on all three.

What happensWhat syndication does
The listing is enteredCopied out to the portals over hours or a day
A detail is corrected in the MLSThe correction follows, at each portal's own speed
A portal is switched offThat site drops the listing; the others keep it

The MLS is the source. The portals are copies, and copies lag.

Part 3 of 4

What people get wrong

That each portal is listed separately. One entry feeds them all, which is why the MLS record has to be right.
