How GPADLAB protects editorial trust.
This policy explains how we handle testing claims, product reviews, sources, outside contributors, commercial relationships, outbound links, corrections, and the line between evidence and inference.
Last updated: September 4, 2026
Four principles behind the work
Accuracy before certainty
We prefer a narrower claim we can support over a stronger claim that merely sounds authoritative. Estimates, heuristics, browser-observed values, manufacturer specifications, and calibrated measurements should be identified for what they are.
Evidence before scoring
Testing claims should be tied to the method that produced them. Where a browser API cannot observe a physical quantity directly, GPADLAB should not present the result as though it came from laboratory hardware.
Editorial independence
Ratings, verdicts, technical conclusions, and corrections are editorial decisions. Affiliate relationships, supplied products, sponsorships, or manufacturer access do not buy a more favorable conclusion.
Named accountability
Articles and reviews should identify the person responsible for the work. External contributors must disclose relevant commercial relationships and provide a credible basis for their expertise or firsthand experience.
How editorial decisions are made
1. What this policy covers
This policy applies to GPADLAB editorial content, including reviews, technical explainers, troubleshooting content, testing methodology, blog articles, comparisons, buyer guidance, and approved outside contributions.
The purpose is straightforward: readers should be able to tell what GPADLAB observed, what a manufacturer claims, what an author believes, what is inferred from available evidence, and what remains uncertain.
2. Technical claims and sources
Technical specifications should be checked against primary sources where practical, such as manufacturer documentation, standards bodies, browser specifications, firmware notes, or directly observed test data. Secondary sources may be used when they add context, but they should not silently replace a stronger primary source that is available.
A source does not make a claim automatically true. GPADLAB editors may narrow, qualify, or reject claims when the evidence does not support the wording used in a draft.
3. Measurements, browser tests, and limitations
GPADLAB distinguishes between values exposed by browser APIs, calculations derived from those values, manufacturer-rated specifications, and measurements made with external hardware. Those categories should not be presented as interchangeable.
When a diagnostic uses a GPADLAB-defined threshold or heuristic, that should be described as a GPADLAB threshold or heuristic unless it is based on a recognized external standard. Where a test has meaningful environmental limitations, those limitations belong in the methodology and, when material to interpretation, near the result itself.
4. Reviews and firsthand experience
A GPADLAB hands-on review should be based on genuine access to the product being reviewed. Review copy should distinguish direct observations from manufacturer specifications and broader market context.
Where relevant, reviews should identify testing conditions such as platform, connection type, firmware, testing period, or other factors that materially affect the result. A review should not imply ownership, testing duration, or measurements that the named reviewer cannot substantiate.
5. Contributors and outside experts
GPADLAB accepts selected contributions from people with relevant firsthand experience or specialist knowledge in controller hardware, repair, testing, firmware, accessibility, electronics, input technology, and closely related fields.
A contributor pitch is not accepted because it contains a backlink opportunity. GPADLAB may edit structure, technical wording, headlines, citations, disclosures, and outbound links. Publication remains an editorial decision even after a pitch has been approved.
6. Originality and use of AI tools
Published work must provide original editorial value and must not be copied, spun, syndicated, or republished from another site without an explicit editorial reason and appropriate disclosure.
Use of writing or research tools does not transfer responsibility away from the named author or editor. Authors remain responsible for factual accuracy, sourcing, originality, quotations, disclosures, and any claims that appear under their name. Fabricated sources, invented testing, or unverified technical claims are grounds for rejection or removal.
7. Links, SEO requests, and commercial placement
External links are included because they support a claim, identify a source, provide useful context, or help a reader reach a relevant resource. GPADLAB does not guarantee a followed link, specific anchor text, or permanent commercial placement as a condition of editorial publication.
Paid or sponsored relationships must be disclosed and handled separately from independent editorial judgment. Where a link is compensated, GPADLAB may apply the appropriate sponsored or nofollow relationship and visible disclosure.
8. Conflicts of interest and supplied products
Authors and contributors must disclose material relationships that could reasonably affect how a reader interprets the work. Examples include employment by a manufacturer, agency representation, supplied review hardware, sponsorship, consulting work, or a financial interest in a product or company discussed.
Disclosure does not automatically disqualify a contribution. Hiding a relevant relationship does.
9. Corrections and material updates
GPADLAB corrects factual errors when they are identified and supported. Small spelling or formatting edits may be made silently. A material change to a technical conclusion, measurement interpretation, product verdict, attribution, or other substantive fact should be handled transparently when practical.
If a methodology changes, older results should not be silently represented as though they were generated under the new method. Where historical results remain visible, GPADLAB should preserve or explain the methodology context needed to interpret them.
10. How to report an error
If you believe a GPADLAB page contains a factual error, unsupported technical claim, attribution problem, undisclosed conflict, or material omission, send the page URL and the specific issue to contact@gpadlab.com. Evidence or a primary source is helpful and makes review faster.
