## Domain profiles

Profiles use the URL pattern `https://tll.com/abc.com`, replacing `abc` with a three-letter string.

Each profile can include:

- Current-use classification and supporting evidence
- Organization and brand context where confirmed
- Nameserver, portfolio, parking, sale and active-mail signals
- Domain-specific naming and letter analysis
- Domain-only market value range
- Intrinsic score, structural marketability grade and estimate status
- Comparable developed identities
- A DomainAgents owner-outreach path when appropriate

## Definitions

- **Confirmed public operating use:** Evidence supports an operating company, organization, product, service or public digital identity.
- **Active infrastructure only:** Email or DNS use is present without separate confirmation of a public operating website.
- **No confirmed public operating use:** Public operating use was not established. The domain remains registered; this does not mean it is available to register or that its owner will sell.
- **Acquisition signal:** Observed for-sale, parking, portfolio, placeholder or other evidence relevant to owner research. Signals can overlap with infrastructure or use.
- **Estimated value:** A directional range for the domain asset alone. It is not an asking price, certified appraisal, transaction prediction or valuation of an operating business.

## Dataset

Three positions and 26 letters produce 17,576 possible combinations. The current TLL release contains all 17,576 analyzed profiles, including WWW.com.

## Media and evidence

- Company and organization logos are supporting identity context. Their image descriptions name the associated organization and domain where that identity is known.
- Website captures are supporting visual context. Classification evidence is recorded separately and is not inferred from the capture alone.
- Public pages expose crawlable titles, descriptions, canonical URLs, structured data and breadcrumbs. The XML sitemap is the authoritative URL inventory.

TLL is created and operated by DomainAgents. Public classifications and estimates use public website, DNS, registration and market signals. Private DomainAgents offers, counteroffers and negotiation data are not used. DomainAgents may earn fees when owner outreach or a transaction is initiated.
