Search engines like Google help people find information among the billions of pages on the web. They work by using automated programs called crawlers to scan and index websites, then ranking pages based on relevance, quality, and how trustworthy a site appears to be.
Not everything found online is accurate, so evaluating sources is an important skill. Reliable information usually comes from sources that clearly state who wrote it, cite where their facts come from, and are regularly updated, while unreliable sources often lack authorship, use extreme language, or can't be verified elsewhere.
A good habit when researching online is to check multiple sources before trusting a claim, look for the original source of a fact or statistic, and be especially cautious with information that seems designed to provoke a strong emotional reaction rather than simply inform.
