Editorial policy
The standards every Listopedia list follows: sourcing, accuracy, independence, corrections and the use of research tools.
This policy sets the standards that apply to every list and company profile on Listopedia. It is applied before publication and at every review.
1. Accuracy and verification
- Every number, date, price, ownership statement and award is recorded with the source it came from.
- Facts that cannot be verified are left out. Listopedia does not estimate figures that a source does not state, and does not round a range into a single number.
- Third-party estimates are used only when attributed by name (for example, a figure labelled as a Forbes estimate).
- Company-stated claims, such as customer counts or analyst placements, are labelled as the company’s own claims.
2. Hierarchy of sources
When sources disagree, the higher source in this order wins.
Listopedia does not use other review aggregators, crowd-sourced encyclopedias or modelled company “estimates” as a source of fact.
3. Rankings
- Each list states its selection criteria and ordering rule in its Methodology section, before the entries.
- Size rankings are ordered strictly by one stated metric and year; when companies report in different currencies, figures are converted at a stated rate before ordering.
- “Top 50” titles are used only when 50 entries are verified; otherwise the title shows the real number.
- Software and service rankings use published criteria or a disclosed scoring model. A vendor whose pages could not be checked is left out rather than placed on assumptions, and the list says so.
4. Independence and conflicts of interest
- No payment changes an entry’s position or the editorial text about a company.
- Paid placements appear in a separate Featured section and are labelled Ad, Sponsored or Premium partner. Premium partners appear first in the Featured section, never inside the ranking.
5. Neutral language
Entries describe what a product or company does and where it is limited. Every entry lists real limitations as well as strengths. Promotional wording, superlatives without evidence and rhetorical questions are removed during review.
6. Research tools
Research combines AI-assisted collection from primary sources with automated quality checks that confirm each fact has a recorded source, ranks are complete and promotional language is absent. Claims resting on secondary or indirect evidence, such as an ownership change inferred from a website redirect, are confirmed against a primary source, reworded to what the source supports, or removed.
7. Corrections and updates
- Each list shows the date it was last reviewed.
- Corrections are made when a primary source supports them. Send them through the error report form with a link to the source.
- Significant corrections, such as a change of rank or ownership, are made in the list and the review date is updated.
8. Company profiles
Profiles collect the facts recorded across the lists a company appears in. Companies can update the description, logo and image of their profile through the submission form; editors check the text for factual accuracy before publication.
