Real estate marketing glossary

The terms that come up when you're buying real estate marketing tools, in plain English — stripped of the vendor spin so you can read a feature list and know what's actually being promised.

IDX (Internet Data Exchange)

The feed that lets you display live MLS listings on your own website, so visitors search homes on your domain rather than a portal's. An IDX website captures the leads those searches generate and feeds them into your CRM — the difference between renting traffic and owning it.

MLS (Multiple Listing Service)

The regional database where agents list properties for sale and share them with each other. It's the source of truth for listings, and IDX is how that data gets onto your site. Access is tied to your membership of the local MLS.

CRM (Customer Relationship Management)

The system that holds every lead and contact in one place and follows up automatically. For agents it captures leads from any source, routes them, reminds you to call and drips email and text over time — turning a scattered pile of names into a managed pipeline.

Lead nurture

The slow work of staying in touch with a lead who isn't ready to transact yet — most of them — until they are. Done through automated email and text, market updates and timely calls, it's where most deals are actually made, on the fifth or tenth touch rather than the first.

Drip campaign

A pre-built sequence of emails or texts that goes out automatically over days, weeks or months after a lead comes in. It keeps you in front of a contact without manual effort between calls, which is why it's the backbone of lead nurture.

Sphere of influence (SOI)

Everyone who already knows you — past clients, friends, family and the people they refer. The cheapest leads you'll ever get and the highest-converting, because the trust exists already. Growing and staying in touch with your sphere is the long game of the business.

ISA (Inside Sales Agent)

A team member whose job is to respond to and qualify new leads fast, then hand the warm ones to a listing or buyer's agent. ISAs exist because internet leads go cold in minutes and most agents can't drop everything to answer instantly — speed wins the conversation.

CMA (Comparative Market Analysis)

An estimate of what a home is worth, based on recent sales of similar nearby properties. Agents use a CMA to price listings and to win sellers — a sharp, well-presented CMA is often the marketing tool that turns a valuation lead into a listing.

Retargeting

Showing ads to people who already visited your website or engaged with your content, rather than cold audiences. It keeps you in front of buyers and sellers who showed interest but didn't convert, usually on Facebook, Instagram and Google, at a much lower cost per lead.

Portal leads

Buyer and seller leads bought from Zillow, Realtor.com and similar sites that sell access to their traffic. High volume but early-stage and expensive per closing — they only pay off if you have a CRM and follow-up system to nurture them over time.

Lead-to-close (conversion rate)

The share of leads that turn into closed transactions. It's the number that actually matters, because the gap between a 1% and a 5% rate is almost never the quality of the leads — it's whether anything followed up with them.

Lead capture

Getting a visitor's contact details in exchange for something — a saved search, a home valuation, a buyer guide, an open-house sign-in. Without capture, traffic and footfall are just numbers; capture is the moment a stranger becomes a lead you can work.

Email service / campaigns

The tool that sends your marketing email — newsletters, listing alerts, market updates and automated drips. What matters for agents is whether it ties into your CRM and contacts so the right message reaches the right person at the right moment.

Branding kit

The consistent look and voice — logo, colors, templates, bio, photography — that makes your marketing recognizably yours across every platform. Tools like done-for-you template libraries exist largely so agents can stay on-brand without designing each post from scratch.

Listing presentation

The pitch an agent makes to win a seller's business — covering pricing, marketing plan and why you. Strong branding, a sharp CMA and a clear marketing stack all feed into it, which is why the listing presentation is where your marketing investment shows up.

SEO (Search Engine Optimization)

The work of earning search traffic to your website over time — for neighborhood pages, listings and buyer/seller guides — so leads find you without you paying for every click. It's slow to pay off but compounds, which is why a good IDX website is a long-term asset.
