01 / WHY IT MATTERS

FROM SOURCE PAGE TO USABLE RECORD

Transformation should add structure, not hide the evidence.

Our proprietary research and web-indexing system is built to surface blue-collar job pages that conventional datasets can overlook. The discovery mechanics stay private, while buyers can still tell what came from the source, what was normalized, what was inferred and when it was observed.

02 / EVALUATION CRITERIA

WHAT BUYERS SHOULD EXPECT

Evidence that makes the data easier to trust.

01

Discover and observe

Surface hard-to-find public job pages with the proprietary indexing system and record when a listing is observed.

02

Extract and preserve

Capture useful source values and retain the route needed to inspect the original public listing.

03

Classify and normalize

Use deterministic rules and AI assistance to make occupations, locations and selected fields more comparable.

04

Disclose and verify

Ship field definitions, scope, snapshot dates, lifecycle rules and known limitations with the data.

BUYER QUESTIONS

What to confirm before you use the data.

Ask about a specific market, field or delivery requirement.

[email protected]
01Does AI create or rewrite the job listings?

No. AI assists with classification, normalization and selected field enrichment. The vacancies originate from public employer sources, and source context is retained.

02How are duplicate records handled?

Source identity and repeated observations provide the basis for deduplication and lifecycle logic. Exact matching rules should be documented for the commercial dataset rather than inferred from this overview.

03What do first seen and last seen mean?

They describe successful source observations. The precise cadence and the rule for deciding that a listing is no longer active should be included in the delivery methodology.

04Can buyers inspect normalized and original values?

That is the intended trust model. Ask for a sample field dictionary to confirm which source values and normalized fields are included in the delivery you are evaluating.

THE SOURCE STRATEGY

The blue-collar jobs hidden in plain sight.

Most job datasets are strongest around major boards and standard ATS footprints. Blue Collar Job Data uses a purpose-built research and web-indexing system to surface hard-to-find public blue-collar job pages, especially from small and specialist employers.

79.9%

of 174 sampled Dutch metal employers with an own-site opening were found on neither Indeed nor Nationale Vacaturebank under the study rules.
