1. What kind of resource would have the information I want (and "a Website" is not specific enough).
2. What tool is the best to help you find that kind of source (search engines, like Google, are one kind of tool, but not the only kind)
3. How will I tell that tool what I am looking for?
There are any number of systems and checklists recommended for evaluating the quality of websites.
Be wary though, being able to "check the boxes" in a checklist is NOT evidence of the quality and reliability of a website
In the past, you may have used a rule of thumb that ".edu" was better becasue it was "educational", or ".org" was better than ".com", or other things like that. Throw those rules away.
All the Domain ( the "dot whatever") tells you is what kind of institution owns the space. It says nothing about the quality, accuracy, or bias of the information. Anyone in a school, including students who are younger than you, can have a ".edu" website. White Supremacist groups are usually non-profit groups (".org"), and the New York Times is a for-profit (".com"), but very reputable source.
Two letter domains (ex. ".uk" (United Kingdom), ".io" (British Indian Ocean Territory), ".co" (Colombia)) only tell you where a website is registered.
Evaluating URLs / Web Addresses
Carefully reading website URLs is important when evaluating websites. Many Fake News and spoof sites purposefully use URLs that are very close to existing ones to make them seem credible at a glance. An official sounding website name is NOT proof of quality. The classic example is that a White Supremacist group that happens to own the ".org" URL with the name of a very famous civil rights activist, and they use it to add fake credibility to the intentionally biased and misleading information on the site.
Lateral Reading: You learn more about the quality and authority of a source by reading outside the source, than by looking inside it. You should not trust the website itself to tell you if it is a good site or not.
How a website looks does not tell you whether or not a site is reputable: ugly websites can have great information (but may be a sign of age), and some low quality, or fake, websites are intentionally designed to be visually pleasing (or even copy the look and feel of existing websites) in order to put you at ease and make you trust them.
However, looking at how a page is designed can give you clues as to the quality of a website.
