IDX lead capture: settings that convert without annoying buyers

An IDX website exists to turn listing searches into conversations. The settings that control that conversion are mostly in your IDX Broker control panel, and small changes there decide whether a buyer signs up, leaves, or never sees a reason to share an email address.

This guide covers the levers that matter: registration rules, saved searches and alerts, listing contact forms, routing, follow-up and the compliance basics behind all of it. It assumes your site is already connected. If not, start with IDX on WordPress.

Forced versus optional registration

IDX Broker gives you two kinds of sign-up prompts:

• Request registration. A pop-up asks the visitor to sign up, but they can close it and keep browsing.
• Force registration. The visitor cannot continue without signing up. If they decline, they are sent back to the home page or the previous screen.

Both can be set for five page types: search pages, map search pages, results pages, details pages and photo galleries. Requests can be recurring (shown again every N pages until the visitor registers) or non-recurring (shown once, then dropped if skipped). Force rules use a “pages viewable before registration” number.

The tradeoff

There is no setting that is right for every market, so think about it in terms of what each choice costs.

• Force early and you collect contact details from more of the visitors who stay, but you risk losing people who were only browsing and are not ready to hand over an email on the first listing.
• Never ask and visitors browse freely, but you have analytics instead of leads.
• Request early, force late gives casual browsers room while asking engaged buyers, the ones viewing many detail pages, to commit. A visitor who has opened many detail pages is showing more interest than one on their first.

Where to set the threshold

IDX Broker’s Lead Registration screen (Leads, then Lead Registration) offers three presets:

• Conservative: no request or force rules.
• Balanced: a one-time request before the featured properties and featured open houses pages, and forced registration after five details pages.
• Aggressive: a recurring request every three results pages, and forced registration after three details pages.

For a custom setup, IDX Broker’s documentation suggests a starting point some clients have reported good results with: request on photo gallery pages, request after the first or second details page, and force after the seventh or eighth. IDX Broker is careful to say this is not a scientific analysis, and you should treat it the same way.

You can also stagger the two. For example, a request every third search page with a force on the tenth means the visitor sees requests on pages three, six and nine, then must register on page ten.

Our practical approach:

1. Start with requests only for the first week or two, and watch sign-ups and bounce rate.
2. Add a forced rule on details pages at a high threshold.
3. Lower the threshold gradually if lead volume is too low, and stop when quality drops.
4. Use per-page rules for exceptions. In IDX Broker you can override the global rules for a single page under Design, Website, Page Templates. A saved link you share on social media can be gentler than your general search.

Write a custom form message that explains the benefit, such as saved favorites and instant alerts, rather than a generic “Please register.”

Saved searches and listing alerts

Saved searches are the strongest reason for a buyer to register willingly. IDX Broker lets leads save searches and properties, and sends email updates automatically:

• Saved search updates include newly listed properties that match the search.
• Saved property updates go out when a core field changes, such as price, status, description, square footage, address, beds or baths.

You can also build saved searches for a lead yourself under Leads, then Manage. IDX Broker frames this as a way to show the value of working with an agent who knows the market. After a first call, set up the search you discussed and leave “Receive Updates?” checked.

A few settings worth checking:

• Reply-to address. If you leave it blank, leads cannot reply to alert emails. Add one.
• Copies. Choose a copy of each update or a weekly summary so you know what leads are receiving.
• Footer details. Alert footers pull contact information from your Account Details, so keep that current.
• Appearance. Alerts do not use your global wrapper. Create a separate page wrapper for property updates if you want them branded.

Contact forms on listing details

The listing details page is where intent is highest. A buyer looking at one specific home with a question is a better lead than someone who registered to see more photos.

• Keep the form short. Name, email, an optional phone and a message is enough.
• Prefill the message with the listing address so the agent knows what the inquiry is about.
• Offer a “schedule a showing” option alongside general questions.
• On WordPress, the IMPress lead signup shortcode has options such as whether to show a phone field and which agent to assign, so standalone signup forms can match the rest of the site.

One setting to watch on office accounts: IDX Broker lets you switch agent contact links to plain mailto links, but its documentation warns those contacts are then not recorded in IDX lead management. Keep inquiries inside the system so nothing is lost.

Lead routing basics

On a single-agent account, lead notifications go to the primary email on the account, so make sure it is an inbox someone checks.

On office accounts, IDX Broker assigns leads in this priority order:

1. System-assigned agent: once you assign a lead in the control panel, it stays with that agent.
2. Manually selected agent: if enabled, the visitor picks an agent on the form.
3. Agent bio cookie: a visitor who arrives through a link carrying an agent’s ID stays tied to that agent.
4. Listing owner: an inquiry on a listing owned by an agent in the account goes to that agent.
5. Contact routing rules: round robin, rules by “core fields” such as city or price, or both.
6. Account email: everything else goes to the primary contact.

If you use round robin, IDX Broker recommends advancing to the next agent when a form is submitted rather than when it loads, so no agent gets skipped. Brokerages with larger teams can find more on our brokerage page.

Follow-up speed

Settings only produce a lead. What happens next decides whether it becomes a client.

A frequently cited 2011 Harvard Business Review study of online sales leads found that “most companies are not responding nearly fast enough.” The practical lesson for IDX leads is simple: a buyer who just registered may still be on your site, looking at homes, so the sooner you reach out the more relevant your message is.

• Make sure lead notifications reach whoever is on duty, not an inbox nobody watches.
• Decide in advance who covers evenings and weekends.
• Make the first touch useful: reference the listing or search they looked at, not a generic script.
• Use the lead’s page history in IDX Broker (also visible in the IMPress plugin) to see what they viewed before you call.
• Set up a saved search for them on the first contact so they keep receiving relevant alerts.

Compliance basics

This section is general information, not legal advice. Talk to your broker or an attorney about your specific practices.

Email: CAN-SPAM

The FTC’s CAN-SPAM compliance guide covers commercial email. Its main requirements include:

• Accurate “From,” “To” and routing information.
• Subject lines that reflect the content.
• Clear disclosure when a message is an advertisement.
• A valid physical postal address.
• A clear way to opt out, honored within 10 business days.
• Responsibility even when another company sends email on your behalf.

Keep your Account Details accurate, since alert footers use them, and make sure any separate newsletter or drip tool meets the same standards.

Calls and texts: TCPA

The FCC’s consumer guide explains that autodialed or prerecorded calls and texts to a wireless number require the person’s consent, and that commercial texts require written consent, which can be collected through a website form. Consumers can also revoke consent at any time in any reasonable way.

If you plan to text or auto-dial IDX leads, add clear consent language to your registration and contact forms, store the record, and honor opt-outs quickly. Read the official FTC and FCC pages for the full rules.

Quick settings checklist

• Registration: requests on, force on details pages at a moderate threshold.
• Custom registration message that explains the benefit.
• Per-page exceptions for social and campaign saved links.
• Email updates: reply-to address set, copies on, footer details current.
• Listing contact forms short and recorded in IDX lead management.
• Routing tested with a real form submission on each path.
• Instant notifications and an after-hours plan.
• Consent language reviewed for email and texting.
