Methodology & independence
The B2B Buyer Lab editorial team researches services, pricing, platform experience and buyer fit. This page explains what our labels mean and what a source can establish.
What a check establishes
Reading a service page establishes what the provider says it offers. A partner-directory check can establish a listed credential at that time. Neither establishes customer outcomes. Demos, interviews and first-hand tests require their own dated observations; we do not infer them from a public listing.
Evidence labels
Source recorded
A statement recorded from linked material. This label alone does not establish an independent check or current accuracy.
Provider reported
A provider-published outcome, client claim or testimonial. Treat it as a claim unless corroboration is documented.
Research note
Context or an editorial assessment. Follow the source and distinguish the observation from the interpretation.
Not verified
The record explicitly identifies missing, unavailable or unverified information.
Proposed scoring rubric — 100 points
Current directory lists are alphabetical and unscored. Blog articles may publish editorial rankings for a specific buying need, with the reviewed sample, criteria, priority order and treatment of missing information explained in the article. These are editorial judgments, not scores calculated using the proposed framework below. Any future points-based ranking will publish its weights and evidence requirements.
| Dimension | Weight | What it measures |
|---|---|---|
| Service capability | 20 | Depth and completeness of relevant delivery |
| Demonstrated outcomes | 20 | Quality, specificity, and relevance of case evidence |
| Method and measurement | 15 | Repeatable process, metrics, reporting, accountability |
| Practitioner credibility | 10 | Named people, relevant experience, visible expertise |
| Commercial transparency | 10 | Scope, minimums, timelines, contract clarity |
| Technical and integration depth | 10 | Ability to work across systems, data, implementation |
| Independent corroboration | 10 | Credible third-party references and customer evidence |
| Buyer-fit clarity | 5 | Clear ideal customer, exclusions, trade-offs |
Dates, scope and corrections
Dates beside sources describe those source checks. An article publication date or a page-layout update is not a new verification of all underlying records. A buyer-fit assessment has its own review date and scope.
Unknown information is stated rather than guessed. A provider description, client logo or published testimonial is not automatically independent corroboration. The label “Lab verified” is reserved for evidence supported by a documented first-hand check; it is not assigned automatically to profile notes.
Substantive corrections are recorded in the public corrections log. Basic inclusion and corrections are free. Paid placements are labeled, payment does not determine editorial rankings, and relevant relationships are disclosed on affected coverage. See the editorial policy.
Methodology updated 13 September 2026. Previous automatic verification labels and blanket source dates were corrected; the scoring rubric remains proposed.
