Do I need IDX on my website? A check for real estate agents

Do I need IDX on my website: the short answer

You need IDX (Internet Data Exchange) only if you want visitors to search listings from your MLS (multiple listing service) on your own site. A website can run without it.

The Try AgentFire button below opens the page where you book a 30-minute AgentFire demo.

What IDX does, and what it does for search

IDX lets an agent show listings from the local MLS on a personal site. AgentFire's own pages differ on search. The tour says Listings Hub pages bring a search benefit; the help desk says IDX property pages often struggle to rank and be indexed.

AgentFire's help desk says Google generally sees IDX pages as "thin content" and advises supplementing them with SEO-friendly material of your own, such as area pages with your own text.

What your MLS requires on an IDX site

Your MLS's own rules govern an IDX site. One example is the California Regional MLS (CRMLS) standards, updated February 4, 2026. They require credit that clearly names the listing broker, office or agent on every listing display for all statuses, and a call to action that names the agent who will respond. Confirm the form your own MLS sets.

NAR's Handbook on Multiple Listing Policy, thirty-fifth edition, 2023, says a participant notifies the MLS before displaying IDX, refreshes feeds at least every 12 hours and shows the brokerage name. Whether an affiliated agent may use IDX on their own site is a local MLS option, subject to the broker's consent and control.

Fair housing applies too. NAR's policy bases listing selection on objective criteria, and HUD's rule (24 CFR 100.75) covers advertisements that indicate a preference, limitation or discrimination. AgentFire's IDX FAQ adds that compensation can no longer be displayed on a listing from an MLS feed. This is not legal advice.

What IDX costs on a built site or as an add-on

AgentFire includes built-in IDX on every site at no extra charge on the $165 Pro plan, with any MLS pass-through fee billed on top; best IDX website for agents compares more sites. Its board pages print $7.00 for California Regional MLS, $10.00 for Canopy MLS and $33.19 for Northwest MLS, a month.

• Placester: $25 a month per approved IDX; the MLS access fee is separate.
• Real Geeks: $10 per board a month.
• Showcase IDX, a WordPress plugin: Essentials $94.95 a month, or $849.50 a year.

Placester says MLS approval typically takes up to 10 business days; Showcase IDX says usually 1 to 5. AgentFire documents no approval steps or times; look your board up by name on its coverage page, because a board is covered only if listed. See AgentFire IDX for its limits.

When an agent website works without IDX

Placester's getting-started checklist says IDX is needed to launch a site; another help article says a site can launch without IDX. Wix's help center says Wix does not support IDX for real estate agents and points to a third-party app or Velo.

Listings Hub, AgentFire's tool for pages for your own listings, turns any listing into a lead capture page. If your brokerage provides your site, ask whether it has a listing search.
