Who publishes it?
Look for an author, responsible organisation, contact page and competence related to the subject. An unsigned institutional page is not automatically invalid, but unclear responsibility limits accountability.
Distinguish the primary source—official body, study, legal text or direct witness—from commentary summarising it. Each reformulation can remove context.
When?
Publication and update dates help determine whether the content still fits. Useful life depends on the subject: history changes slowly, while prices, schedules, rules and software can change quickly.
An old page can remain valuable when it describes its period. It becomes misleading when it presents a past state as current.
What is the evidence?
Find documents, data, methods, examples or links that let you trace the claim. A long bibliography is insufficient when references do not actually support the conclusion.
For a figure, check the unit, period, population and calculation. For a quotation, find the full passage.
What is the interest?
Every author has a viewpoint. Ask whether financial, political, institutional or personal interests may shape the selection and presentation of facts.
Commercial content may give accurate specifications; it is simply less suitable for impartially evaluating the product it sells.
Is it corroborated?
Seek genuinely independent confirmation, ideally from another primary source. Ten pages repeating the same press release are not ten confirmations.
When serious sources disagree, explain the disagreement instead of manufacturing certainty. For high-impact decisions, consult a competent professional.
Separate accuracy from relevance
Information can be accurate yet irrelevant to your situation. A national figure may not describe a town; a rule for professionals may not apply to consumers; an old study may concern technology that is no longer used.
Before accepting a conclusion, state the question precisely: which fact, for which territory, at what date and for which category of people or products?
This step prevents time being spent confirming information that remains beside the point.
Recognise warning signs
An absolute headline, manufactured urgency, an untraceable source, an out-of-context quotation or figures disconnected from their method justify further checking. The same applies when a page hides its author or commercial interest.
No single sign proves that content is false. A combination indicates that the claim should not be repeated before reaching stronger evidence.
Polished design and fluent writing do not compensate for missing proof.
Put corroboration into practice
Suppose a page claims that a new rule is already mandatory. Identify the country and stated date, then find the text or timetable from the responsible authority. Next check whether an independent publication interprets the same provision consistently.
If sources confirm the text but disagree about its application, preserve that nuance. An honest result may be conditional rather than a definitive yes or no.
Record the links consulted and verification date when the decision may need to be explained or reviewed later.
