Work through a concrete question

Try a method. Keep a useful result.

These worked examples show what our tools do and where interpretation still matters.

Read the destination before opening a link

In the fictional address https://account.example@other.example/, the server is other.example. The part before @ is user information, not the destination.

Interpret a change in a rate

A rate moving from 12% to 18% increases by 6 percentage points and by 50% relative to its starting value. Write which measure you mean.

Try the percentage calculator →

Notice a value that changes the average

For the illustrative values 10, 10, 10 and 70, the mean is 25 and the median is 10. Those two measures answer different questions.

Keep evidence and uncertainty together

Record the exact claim, two sources, what each establishes and what remains unanswered. A filled notebook is a trace of your work, not a truth certificate.

04 — Direct answers

Understand first.
Then act.

Short answers designed to stand on their own, followed by an English editorial guide when you need the method, examples and limitations.

01

How do I identify an official website?

Check the domain, the named publisher and the purpose of the page. For an important action, reach the service from a recognised institutional directory or a previously verified address.

Check a website before trusting it
02

Can I trust an answer produced by AI?

Treat it as a starting point when the facts matter. Isolate each claim, open the cited material and confirm important details with a recent source that is competent for the subject.

Learn how to evaluate a source
03

What makes a directory genuinely useful?

A useful directory explains why each destination belongs, identifies its publisher and limits, and helps visitors choose by need rather than presenting an unexplained list of links.

Read the directory guide
04

How should web content be maintained?

Review the claims and outgoing links, not only the publication date. Record meaningful editorial changes and make corrections easy to request.

Maintain content over time
05 — Questions

A clear portal.
Clear limits.

Each external service remains responsible for its content, terms and data practices.

What can I find on World Web Certified?

Direct links, practical web guides and a growing directory of reference websites. Topics include search, AI assistants, browsers, accounts, devices and online services.

Which languages are available?

The homepage and editorial information are available in English and French. 183 practical guides are available in English, alongside the full French collection. Every practical guide has a French counterpart. Directory records and category handbooks are also available in both languages.

How are websites and services selected?

The editorial review considers the identity of the publisher, practical usefulness, clarity, information freshness and the precautions a visitor may need before using the resource.

How can I tell when a page was reviewed?

Detailed guides show their update date and, when external documentation is used, the date on which those sources were consulted.

Which services appear first?

Google is the first general search engine shown and Gemini the first AI assistant. This order is a starting point, not a claim that one tool is best for every task.

Are the listed services partners?

Not unless explicitly stated. A link helps you find a destination and does not imply a partnership or endorsement of all its content or terms.

How can I request a correction?

Use the Contact page and include the relevant URL, the passage concerned and, when possible, a supporting source.
