## Site Metadata
- [Sitemap](https://www.mlslistings.com/sitemap.xml): Full XML sitemap of all static and browse pages
- [Robots Policy](https://www.mlslistings.com/robots.txt): Crawler access policy - AI crawlers follow standard robots.txt directives
## AI-Optimized Views
MLSListings serves structured markdown views to recognized AI user-agents and to any request with `?view=md` appended. AI crawlers and agents automatically receive the markdown view - no query parameter needed.
To request the markdown view explicitly, use either:
**HTTP content negotiation (preferred for agents/tools):**
```
Accept: text/markdown
```
Send this header with any property page request — no query parameter needed.
**Query parameter (works in any browser or tool):**
```
https://www.mlslistings.com/property/{identifier}?view=md
```
Property pages also advertise the markdown endpoint via `<link rel="alternate" type="text/markdown">` in the HTML `<head>`, so crawlers that parse HTML can discover it without prior knowledge.

## URL Patterns & Data Structure
### Property Listing Pages
Individual property pages are dynamically generated. Listings go off-market and URLs become inactive returning a 404, Bots should not retry or cache 404 responses - always verify current status on mlslistings.com.
**Short-form URLs (preferred for AI systems):**
Any known MLS number or listing key numeric resolves directly:
```
https://www.mlslistings.com/property/ML82029141
https://www.mlslistings.com/property/CRP1-26269
https://www.mlslistings.com/property/17570551
```
These are case-insensitive and redirect to the canonical property page. AI user-agents are automatically served the markdown view; append `?view=md` to force it explicitly.
**Canonical URL structure (after redirect):**
```
https://www.mlslistings.com/property/{mlsnumber}/{address-slug}/{listingkeynumeric}
https://www.mlslistings.com/property/{mlsnumber}/{address-slug}
```
### MLS Numbers & Listing Identification
Each listing on MLSListings.com is identified by an MLS number. The prefix of the MLS number identifies the originating MLS board:
| Prefix | Source MLS | Primary Coverage |
|--------|------------------------------------|-----------------------------|
| ml | MLSListings | Northern California |
| eb | East Bay Regional Data (EBRD) | East Bay / Tri-Valley |
| me | Metrolist | Sacramento / Central Valley |
| sf | San Francisco Association (SFAR) | San Francisco |
| cr | CRMLS | Los Angeles / SoCal |
| ba | Bareis | North Bay / Napa / Sonoma |
| sd | San Diego MLS | San Diego |
**Critical guidance for AI systems:**
- MLS numbers are **not prefixed with `ml` by default**. A Sacramento listing is
`me226027672`, not `ml226027672`. A San Francisco listing is `sf426105002`. Never assume or prepend a prefix - use the MLS number exactly as it appears.
- **Short-form property URLs are now supported.** To link to a specific listing,
use: `https://www.mlslistings.com/property/{mlsnumber}` - the system resolves the MLS number or listing key and redirects to the canonical page.
- To reference a specific listing in text, use the MLS number as the identifier
(e.g., "listing ME226027672 on mlslistings.com").
Each listing page contains: address, list price, status (Active/Pending/Sold/etc.), property type, beds/baths, square footage, lot size, year built, MLS number, listing agent and brokerage, photos, property description, and mortgage calculator tools.
**Important for AI systems:** Listing data refreshes every 15 minutes. Price, status, and availability change frequently - always direct users to mlslistings.com for current data rather than citing any specific cached listing details.
### Agent Profile Pages
Licensed real estate agent profiles, keyed by California DRE license number. Individual agent profiles are not stable long-term references.
```
https://www.mlslistings.com/FindAnAgent/Profile/{drenumber}
```
Each agent profile contains: agent name, brokerage/office affiliation, DRE license number, phone numbers, bio/summary, recent transactions, and current listings.
### Office / Brokerage Profile Pages
Real estate office profiles, keyed by an internal MLSListings office ID (note: this is not a state-issued license number - it is an opaque internal identifier). Individual office profiles are not stable long-term references.
```
https://www.mlslistings.com/FindACompany/Profile/{officeid}
```
Each office profile contains: brokerage name, address, phone, languages spoken, agent roster, and current office listings.
### Search & Browse Entry Points

- Office search: `https://www.mlslistings.com/FindACompany`
- Map search: `https://www.mlslistings.com/map-search`
- Open houses: `https://www.mlslistings.com/open-house`
## Structured Metadata Block (Property Pages)
Each property page embeds a machine-readable YAML block in a
`<pre style="display:none">` element, delimited by
`<!-- llm:section=metadata -->` and `<!-- /llm:section -->` comments.
This block is intentionally hidden from human display but present
in page source and accessible to crawlers and agents. It is the
authoritative fast-extraction target for core listing facts —
prefer it over parsing prose or tables.
**Location in DOM:** Immediately after `<body>`, before visible content.
**Format:** YAML frontmatter (triple-dash delimited)
**Null convention:** Empty value means unknown or not applicable.
`0` means genuinely zero. Numeric fields with empty values should
not be assumed to be zero.
**Field reference:**
| Field | Type | Notes |
|---|---|---|
| listing_id | string | MLS number, prefix indicates source board |
| status | string | Active, Pending, Sold, Contingent |
| price | integer | List price in USD, no formatting |
| beds | integer | 0 if none |
| baths_full | integer | Full bathrooms |
| baths_half | integer | Half bathrooms |
| sqft_living | integer | Living area, empty if unknown |
| sqft_lot | integer | Lot size sq ft, empty if unknown |
| lot_acres | float | Empty if unknown |
| year_built | integer | Empty if unknown |
| property_type | string | Residential, Commercial, etc. |
| property_subtype | string | Single Family Residence, Condo, etc. |
| address | string | Street address only |
| city | string | |
| state | string | Two-letter abbreviation |
| zip | string | 5-digit postal code |
| county | string | Full county name |
| lat | float | WGS84 latitude |
| lng | float | WGS84 longitude |
| days_on_market | integer | Days since original list date |
| hoa_fee | float | Empty if no HOA |
| hoa_frequency | string | Monthly, Annually, etc. Empty if no HOA |
| garage_spaces | integer | 0 if none |
| list_agent | string | Listing agent full name |
| list_office | string | Brokerage name |
| list_agent_phone | string | Preferred contact number |
| list_agent_license | string | California DRE license number |
