Methodology

How Find Land Surveyor works.

A walkthrough of how we source listings, verify licenses, rank results, filter low-quality leads, and route estimate requests to surveyors. Last reviewed 2026-05-09.

Find Land Surveyor is a national directory of 10,041 licensed land surveying firms across 50 states. This page documents the methodology behind the directory: how firms get listed, how rankings work, what happens to your estimate request after you submit it, and how we handle corrections and complaints. It is written so you can verify, in detail, that the directory works the way we say it does.

1. How firms get into the directory

Every firm in the directory enters through one of two paths.

Public-records compilation

The directory is compiled from publicly available state licensing board records and publicly available business directories. State by state, we identify firms that hold an active Professional Land Surveyor licence in that state, match them against publicly listed business records (name, phone, address, website), and assemble a county-level listing. Firms that cannot be matched against the state's public licensing data are not listed.

Profile claims

Once a firm is listed, the firm's owner can claim the profile for free. Claiming verifies that the firm controls the listing and unlocks editing of the firm's description, website link, photos, and service-area selections. Claimed firms also receive estimate requests routed by the directory (see Section 5 below).

What we deliberately exclude

  • Equipment vendors and instrument dealers. Identified by name patterns and excluded.
  • Surveying-supply companies, software vendors, and trade associations. Not licensed surveying firms; excluded.
  • Federal agencies. The US Geological Survey, BLM offices, and similar entities perform survey work but are not commercial surveying firms; excluded.
  • Firms in states where licensing cannot be reasonably verified. If we can't verify against the state board, we don't list.

2. How we verify licences

For each firm, we check at least one of the following against the public licensing data published by the state board:

  • The firm's name appears as a registered business associated with one or more individually licensed Professional Land Surveyors.
  • An individual licensed Professional Land Surveyor at the firm appears in the state's licensee roster.
  • The firm holds a state-issued Certificate of Authorization (where the state requires firm-level registration in addition to individual licensing).

The exact verification approach varies by state because state licensing data varies by state: some publish a comprehensive public roster; others publish only individual licensees; a few publish only firm registrations. Where we cannot verify against any of the above, the firm is not listed.

3. How rankings work

Within a state, county, or city page, listings are displayed in two groups.

Featured listings

Featured listings appear at the top of the page and are clearly labelled with a "Featured" badge. Featured placement is a paid subscription purchased by the firm. See the Affiliate & Funding Disclosure for pricing and the For Surveyors page for full details. Featured placement does not affect any quality signal we display, including licence verification status, Google rating, or rating count. It affects only display position and presentation features.

Organic listings

Organic listings are unpaid and ranked by an objective scoring formula:

score = rating_value × log10(rating_count + 1)

This formula rewards both rating quality and rating volume, while preventing a single 5-star review from outranking a long-established firm with hundreds of strong reviews. Ratings are sourced from public Google business profiles. Firms with no public Google rating are ranked below firms with any rating. Within ties, claimed profiles rank above unclaimed (because claimed profiles indicate an active firm that has confirmed its listing).

4. The quality gate on estimate requests

Before any estimate request is routed to a surveyor, it passes through an automated quality gate. The gate exists because surveyors who participate in the directory consistently report two failure modes: requests that are not from real prospects, and requests that are designed to extract free advice rather than purchase a survey. Filtering these protects the surveyors' time and keeps response rates high for the requests that do get through.

A request is filtered out (saved to our database for audit but not routed) if any of the following is true:

  • No property address. A meaningful estimate cannot be prepared without one.
  • Timeline indicates "just exploring." Genuine intent is required; informational browsing belongs in our guides, not in a surveyor's inbox.
  • Submitter identifies as the neighbour, not the property owner. Boundary disputes are best resolved by the property owner engaging a surveyor directly.
  • Free-text matches price-shopping or tire-kicker patterns. Examples: "free check," "just curious," "called several other surveyors," "shopping around," "cheapest." These were identified by surveyors in our research as automatic disqualifiers.
  • Internal test submission. Recognized by signature patterns and excluded from routing.

Filtered requests are not routed to surveyors and are not counted toward any reported lead-volume figure. The submitter sees a soft acknowledgment and is directed back to the directory or to relevant guides.

5. How a qualified estimate request is routed

Once a request passes the quality gate, the routing pipeline runs as follows:

  1. The request is recorded in our database with a unique lead ID.
  2. Routing identifies up to three surveyors in the county the request specified, using this priority order:
    • Claimed surveyors in the county fill the first slots (in ranking order).
    • If fewer than three claimed surveyors are available, the remaining slots are filled by top-ranked organic surveyors in the county that have a working email address on file.
  3. Each selected surveyor receives the full request by email, including the requester's name, contact details, property address, project type, project notes, and any pricing context that was shown to the requester at submission time.
  4. The requester is told to expect contact within one business day. The actual response time is determined by the receiving surveyors, not by the directory.
  5. A copy of every routed request is retained for audit purposes for up to 24 months, after which it is deleted or anonymized (see the Privacy Policy).

Lead exclusivity

Each estimate request is sent to up to three surveyors who can compete for the work. Requests are not exclusive to a single surveyor. This model is disclosed to requesters at submission time and to surveyors when they receive the request.

No per-lead fees

We do not charge surveyors a fee per lead, do not run lead auctions, and do not sell leads to third parties. Featured Profile subscribers and unclaimed surveyors at the top of the organic ranking receive routed leads as a function of their position, not a function of payment per lead.

6. Refresh cadence

The directory is re-verified against public licensing records on a quarterly schedule. Each quarter we:

  • Re-check the public licensing roster for each state and flag any firm whose individual licence appears to have lapsed for review.
  • Add new firms that have appeared in the public licensing data since the prior refresh.
  • Remove firms whose business details (phone, website, address) are no longer reachable after a documented attempt to contact.
  • Update Google rating and rating-count signals used in organic ranking.

In addition, we act on individual correction requests within five business days of receipt, regardless of the quarterly cycle.

7. Corrections and complaints

If a profile contains incorrect information, the fastest path to a correction is to email [email protected] with the URL of the page and a description of what needs correcting. We respond within five business days. Corrections are free; we do not require the firm to claim a profile or to subscribe to anything before correcting an error.

If you are the firm's owner and you want to take ongoing control of the listing, claiming the profile is also free. The claim flow is described on each profile page.

For complaints about a surveyor's conduct, please contact the appropriate state licensing board. The board, not the directory, is the authority on professional discipline.

8. What we do not do

  • We do not sell personal information, ever.
  • We do not run lead auctions or charge surveyors per-lead fees.
  • We do not accept payment in exchange for removing a negative review or burying a complaint.
  • We do not write editorial guides designed to favour any specific firm or product.
  • We do not pre-screen surveyors for project-specific suitability or guarantee any surveyor's work. Inclusion in the directory is not an endorsement.
  • We do not list firms in states where we cannot reasonably verify licensing against public records.
