Create Saved Search Links for Areas That Are Not a City

In short
  • Build a search link for a neighborhood, district or local name.
  • Draw the area once and the link returns the listings inside it.
  • Skip drawing: describe the area to AI and paste the line in.
  • One saved link works behind a tile, a menu item or a text link.

Almost every agent website has a "Search by area" section: a row of tiles, each one opening a ready search. Behind every tile is a saved search link. A town or a ZIP code is easy, because the MLS carries those values and you pick them from a list. A neighborhood, a downtown district, a corridor along one road or a name only locals use is not in that list, and those are the names people type into a search box. Polygon search covers them: you draw the area on a map, and the saved link returns everything inside the shape.

Decide how the area should be defined

First check whether the area already exists as a value in your account. A filter on a real MLS field updates itself and needs no maintenance, so it beats a drawn shape whenever it is available.

What the area is How to build it
An incorporated city or town City filter
A postal area ZIP code filter
A subdivision the MLS lists by name Subdivision filter
A neighborhood, district, corridor or local name Map polygon
An area smaller than one ZIP code Map polygon
A polygon boundary is an opinion
Unofficial areas have no official boundary, so whatever you draw becomes the definition of that area on the site.

Draw the area in IDX Broker

  1. 1 Open Saved Links and create a new one

    In your IDX Broker account, open Saved Links and click Create Link. This is the same screen that holds every ready search you have already built.

  2. 2 Pick a search page from the Polygon group

    The first step of the wizard asks which search page to use. Open the dropdown and look past the plain Search entries: there is a Polygon group, and picking a page from it is what turns on the map drawing tools. Standard Results is the usual choice. Then click Next Step.

    Pick a search page dropdown with Standard Results selected under the Polygon group
  3. 3 Draw the shape on the map

    The next step shows a map with drawing tools in the top left corner. Choose the polygon tool, then click once for each corner of your area. Follow real edges where you can, such as a highway, a river or a city limit.

  4. 4 Close the shape

    Keep clicking corners until you are back where you started, then click the first point again to close the shape. The map will tell you to do this. An unclosed shape is not a polygon and will not filter anything. When the area is filled in, click Next Step.

  5. 5 Name it and save

    Give the link a Page Title. Use the area name exactly as it will appear on the website. Save, and the link is ready to use anywhere on your site.

Paste a polygon you already have

If you already have the coordinates, from a previous setup, a mapping tool or an AI assistant, you can paste them in instead of drawing. Open the saved link and click the magnifier icon on its row, which opens Edit Search Criteria.

Inside, switch to the Edit Link By Hand tab. This is a plain text field holding the whole query behind the saved link. A working polygon query has this shape.

pgon=25.7400+-80.2100,25.7530+-80.2145,25.7660+-80.2155,25.7790+-80.2085,25.7900+-80.2040,25.8000+-80.2000,25.8100+-80.1930,25.8115+-80.1700,25.8125+-80.1450,25.8120+-80.1240,25.8060+-80.1210,25.7950+-80.1235,25.7840+-80.1270,25.7730+-80.1295,25.7660+-80.1320,25.7700+-80.1520,25.7640+-80.1720,25.7530+-80.1830,25.7440+-80.1900,25.7400+-80.2000,25.7400+-80.2100&radius=&layerType=polygon&clat=25.7760&clng=-80.1680&zoom=12&pt=1&srt=newest

That exact line sits in a saved link on our demo account, so you can open the test link and see how it came out. It covers downtown Miami, Brickell, Edgewater and South Beach, and its outline has twenty points, plus the first one repeated at the end, because the edges follow I-95, the causeway and the ocean. Your own line keeps the same format, with your own points.

Get the coordinates from AI

Instead of drawing every area by hand, describe each one to an AI assistant and ask for the coordinates in the format above. How close the shape lands depends on how specific your description is, so name the roads, the landmarks and the edges you do not want crossed.

plain
I need a polygon for an IDX Broker saved search link.

Area: [area name, the town and state it belongs to, the roads or
landmarks that define its edges, and anything it must not cross]

Return one single line in exactly this format and nothing else:

pgon=LAT+LNG,LAT+LNG,...,LAT+LNG&radius=&layerType=polygon&clat=LAT&clng=LNG&zoom=12&pt=1&srt=newest

Rules:
- follow the real edges of the area, in clockwise order
- repeat the first point as the last point so the ring is closed
- latitude first, then a plus sign, then longitude (longitude is negative)
- commas between points, no spaces anywhere in the line
- set clat and clng to the center of the shape

Paste the line the assistant gives you into Edit Link By Hand and save. For the next area you change only the description block at the top and keep the rest of the prompt as it is.

Treat the output as a first draft
AI is good at approximate shapes around known roads and landmarks, and unreliable on exact municipal boundaries. Some of these areas have no official boundary to be right about in the first place.

Check the result before you use it

Open the finished link and check two things. First, the shape sits where you expected. Second, it returns listings, because a tile that opens an empty result page is worse than no tile at all. If the result comes back thin, widen the shape or drop that area from the list.

The finished area link on a site: the shape, and the listings inside it

Once a link is saved it is simply a URL, so it works behind an area tile, an image card, a menu item or a text link, on any platform. Nothing else on the site needs to change.

No. The shape is fixed until you edit it. That is the trade-off against a City filter, which follows the MLS automatically. If the local understanding of an area changes, you edit the link by hand.
Yes, and a listing inside both shapes will appear under both area names. That is usually fine for neighboring areas. If you want them to be exclusive, move the shared edge of one polygon.
