English:Evaluating Websites and Online Sources
Evaluating Websites and Online Sources
Introduction
The internet can help you learn almost anything, but not every webpage, video, post, or image is equally trustworthy. Some online sources are carefully researched. Others may be outdated, one-sided, made mainly to sell something, or simply wrong. In this aiMOOC, you will learn how to slow down, ask useful questions, compare sources, and decide what information deserves your trust.
By the end of the course, you should be able to explain why a source was created, identify clues about its author and evidence, check whether information is current, compare claims across several sources, and use lateral reading before accepting or sharing an online claim.
A key idea: A professional-looking website can still contain weak information. Good evaluation is not about guessing from colors, logos, or design. It is about checking the source, the evidence, the purpose, and what other reliable sources say.
Why Website Evaluation Matters
You use online information for school projects, hobbies, games, news, health questions, science facts, and everyday decisions. When you choose a source, you are choosing what information enters your work and your thinking.
A weak source can lead to a weak conclusion. A strong source gives you a better chance of using accurate, useful, and well-supported information. Evaluating sources is part of information literacy, media literacy, and digital citizenship.
Trust is not all-or-nothing. A website might be useful for one purpose but not for another. A museum website may be strong for information about its own collection. A company website may be useful for learning what that company sells, but you may need independent sources to judge whether its product is the best.
Start with Your Question
Before judging a source, ask: What am I trying to find out? The best source depends on your task.
For a school report about volcanoes, a science museum, university, geological survey, or well-edited encyclopedia may be useful. For a personal opinion about a new game, a review or forum might be useful. For an official rule, look for the organization that actually makes or publishes that rule.
The goal is not to find a website that agrees with you. The goal is to find information that helps you answer your question fairly and accurately.
The CHECK Method
Use the word CHECK as a simple reminder when you inspect an online source.
C — Creator
Ask who created the information. Look for an author, organization, editor, or publisher.
Useful questions include: Who is responsible for this page? Does the author explain their role or experience? Is there an "About" page? Can you find information about the organization somewhere else?
An author's name alone does not prove that the information is reliable. The important question is whether the creator is a suitable source for the topic and whether other evidence supports the claim.
H — How Do They Know?
Strong sources usually show how they know what they claim. Look for evidence such as measurements, photographs with clear context, quotations, links to original documents, references, or explanations of where facts came from.
If a page makes a big claim but gives no evidence, treat the claim carefully. Ask, "What supports this?" and "Can I find the original source?"
A citation is a clue that you can follow. It does not automatically make a claim true, because citations can be weak or misunderstood. Your job is to check whether the cited source really supports the claim.
E — Evidence from Elsewhere
Do not let one unfamiliar page be your whole investigation. Open a new tab and see what reliable sources say about the same claim, person, or organization. This is called lateral reading.
Lateral reading means looking around a source instead of staying only inside it. You can search for the organization, check what independent sources say about it, and compare the claim with other strong sources.
When several independent, trustworthy sources agree on the same well-supported fact, your confidence can increase. If sources disagree, do not simply choose your favorite. Find out why they disagree, what evidence each one uses, and whether newer or more direct evidence is available.
C — Current and Context
Check when the information was published or updated. Some facts change quickly, while others stay useful for years.
For example, an old webpage about the planets may still contain useful basic information, but an old page about an election result, a software version, or a school timetable may no longer be current.
Also check the context. A photograph, quotation, or graph can be real but still be used in a misleading way if it is removed from its original time, place, or explanation.
K — Key Purpose
Ask why the source exists. Common purposes include informing, teaching, entertaining, persuading, selling, collecting attention, or encouraging people to take action.
Purpose does not automatically make a source good or bad. A shop can accurately describe the size of its own product. But if the same shop claims its product is "the best," you should look for independent evidence before accepting that judgment.
Ads and sponsored content can sometimes look similar to ordinary information. Look for labels such as "Ad," "Sponsored," or "Promotion," and notice whether the page benefits when you click or buy.
Read the Web Address Carefully
A web address, or URL, can give you clues about where you are.
Domain Names Are Clues, Not Proof
Endings such as .com, .org, .edu, and .gov may tell you something about a domain, but an ending alone does not prove that every page on the site is accurate or suitable for your task. You still need to check the creator, evidence, purpose, date, and outside coverage.
Look carefully for misspellings or extra words in a domain name. A fake site may try to look similar to a real organization. When a page asks for passwords, money, or personal information and something seems suspicious, stop and ask a trusted adult, teacher, librarian, or caregiver for help.
Important: A secure connection symbol or "https" helps protect information traveling between your device and a website. It does not prove that every statement on the website is true.

This short Commons video demonstrates entering a web address in a browser. Watch where the address appears and notice that the address bar identifies the site you are visiting.
Fact, Opinion, and Claim
A fact is a statement that can be checked against evidence. An opinion expresses a judgment, preference, or belief. A claim is something a person or source says is true and may need evidence.
These categories can overlap in real life. A page may mix facts with opinions. Your task is to notice which statements need checking and what evidence supports them.
Example: "The museum opened in 1998" is a checkable claim. "This is the most exciting museum in the city" is a judgment and depends on what "most exciting" means.
Primary and Secondary Sources
A primary source comes directly from the event, person, organization, experiment, or time you are studying. Examples can include a diary, interview, original photograph, dataset, speech, official record, or first report of an experiment.
A secondary source explains, analyzes, compares, or summarizes information from primary sources and other evidence. Examples can include a textbook chapter, encyclopedia article, documentary, or history article.
Neither type is automatically better. A primary source can be biased, incomplete, or difficult to understand. A good secondary source can add context and compare several pieces of evidence. Choose the source type that fits your question.
Clickbait, Emotion, and Fast Sharing
Some online titles are written mainly to make you click. They may use words such as "shocking," "unbelievable," or "you won't believe." A dramatic headline is a reason to read carefully, not a reason to believe or reject the story automatically.
Strong emotions can make people react quickly. If a post makes you very angry, scared, or excited, give yourself time to check before sharing it.
Ask: What is the exact claim? Who is the source? What evidence is shown? Can I find the original context? What do other reliable sources report?
Images, Videos, and AI-Generated Content
Pictures and videos can be edited, cropped, labeled incorrectly, taken from another event, or generated with digital tools. A realistic-looking image is not proof by itself.
Check who first posted the media, when it appeared, what caption goes with it, and whether reliable sources show the same event. If a dramatic image appears without a clear source, search for more information before you trust or share it.
The same rule applies to text made with automated tools: judge the information by its evidence and sources, not by how confident or polished the wording sounds.
A Four-Move SIFT Strategy
Another useful method is called SIFT. The four moves are easy to remember:
- Stop: Pause before you believe, use, or share a claim.
- Investigate the source: Find out who is behind the information and what others say about that source.
- Find better coverage: Look for stronger or more direct reporting about the same claim.
- Trace the claim: Follow quotations, images, statistics, and statements back to their original context when possible.
SIFT is closely connected to lateral reading because both methods ask you to leave the page and investigate the wider information environment.
A Source Evaluation Example
Imagine you find a page that says, "A new study proves that homework always makes students smarter."
First, identify the exact claim. Words such as "proves" and "always" are very strong. Next, check who published the page and whether an author is named. Look for a link to the study. Check the date. Then open a new tab and search for the study title, the researchers, or independent reports about it. Finally, compare what the original study actually says with the webpage's headline.
You may discover that the study examined only one age group, measured one kind of learning, or found a smaller effect than the headline suggests. The lesson is not to distrust everything. It is to match the strength of your conclusion to the strength of the evidence.
Building a Trustworthy Research Trail
For a school project, keep a simple record of the sources you use. Write down the page title, author or organization, date if available, web address, and the fact or idea you used.
Try to use more than one good source for important claims. When possible, include a source that is close to the original evidence and another reliable source that explains or checks it.

- Trace a Claim: Follow one quotation, statistic, or image from a webpage back toward its original source and explain what changed or stayed the same along the way.
- Resolve a Disagreement: Compare two sources that disagree about a claim and explain which evidence is stronger, what information is missing, and what you would check next.
- Purpose and Perspective: Analyze how the purpose of a museum, company, campaign group, and encyclopedia could influence what each source includes or leaves out.
- Transfer to a New Topic: Apply the same evaluation method to an unfamiliar topic and write a short checklist showing which clues helped you most and why.
Evidence of Learning
Strong evidence of learning includes the knowledge that websites have creators, purposes, dates, evidence, and contexts; the skill of comparing sources instead of trusting a page by appearance; and the ability to explain why a source is suitable for a particular question.
You should be able to produce a source evaluation, a short fact-check, a research trail, a comparison table, a poster or video explaining evaluation steps, and a reasoned conclusion that connects evidence to your judgment.
Transfer is especially important. You demonstrate strong learning when you can use the same habits with a new website, video, image, social-media post, or AI-generated answer, and when you can explain what you would check next if the evidence is incomplete.

The following English Wikipedia article gives broader background on information literacy and the skills used to find, evaluate, and use information.
Media for Further Learning
The media in this course support different parts of the evaluation process. The IFLA infographic gives a visual checklist, the Commons lateral-reading image shows the idea of opening new tabs, the browser demo helps you notice the address bar, and the phishing-warning image connects website evaluation with online safety.
For a guided video review, revisit the Crash Course episodes on digital information and trust. You can also watch a short source-evaluation lesson created for middle school learners.
As you watch any educational video, evaluate it too. Ask who produced it, what evidence it uses, when it was published, why it was made, and what other reliable sources say.
Linked Learning Areas
Evaluating websites connects English reading skills with research, media studies, computer use, online safety, and responsible participation in digital spaces. It also supports science, social studies, history, and other subjects whenever you must decide which information is trustworthy enough to use.
