How to Fact-Check Information You Find Online (A Practical 2026 Guide) - Geeky Nigeria
Every day, millions of people receive information online without stopping to ask a simple question: Is this actually true?
A WhatsApp message claims that a new government policy has been introduced. A social media post says a celebrity has died or a famous fintech is abruptly shutting down operations across the country. A viral video appears to show a recent event, or an article makes a surprising health claim. Someone shares a screenshot and insists that it is proof.
For very many, often than not, the temptation is often to believe, react to, or share the information immediately, but the fact is that information being online does not inherently make it accurate. With misinformation fast spreading across social media, blogs, messaging platforms, and even AI-generated content, knowing how to fact-check information online has become an important digital skill. The wonderful not-so-complicated thing is that you do not even need to be a journalist or professional fact-checker to do the needful.
Today, we are bringing practical and timeless steps you can take in order to verify information before believing or sharing it.
1. Check Where the Information Came From
The top on this list of fact-checking online information is to examine the source. Who published the information? Is it a recognised news organisation, government agency, university, professional organisation or an unknown website?
Do not judge a website solely by how professional it appears! A polished design, impressive logo, or authoritative-sounding headline does not automatically make a source trustworthy. Instead, do due diligence to search for information about the organisation or author outside the original website; this is known as lateral reading.
Research from Stanford found that professional fact-checkers were effective at evaluating online information because they did not simply remain on the website they were investigating but opened other tabs to find out who was behind the source and what independent sources said about it. In simple terms, do not just ask, “What does this website say?” Rather, you should be asking “What do other reliable sources say about this website and its claim?”

2. Look for the Original Source
Social media posts often present information without enough context, and this is something virtually everyone should know by now (in this 21st century). A post may quote a politician, researcher, celebrity, or organisation without providing the original interview, statement, report, or publication. Before accepting the claim, it is important you try to find the original source.
For example, if a post says that a government agency announced a new policy, visit the official website of the agency or verified communication channels, and if it claims that a scientific study discovered something, look for the actual study or information from the institution that conducted the research. This matters because information can change as it moves from one person to another; a statement may be shortened, exaggerated, or removed from its original context.
3. Check the Date
An old story can become misleading when it is presented as new information, and again, this is very common on social media. Frequently, we see this happening with news reports, photographs, videos, and statistics. A genuine image from an earlier event may be reposted during a completely different event, making people believe it is something of a recent stance. Before sharing a story, check when it was originally published, and also ask whether the information is still relevant. A report about a policy, election, technology, price, sporting event, or public announcement may have been accurate when it was published but is outdated today.
Always check the date, especially when a post claims that something happened “today” or "recently."
4. Compare the Claim With Other Reliable Sources
One source may get something wrong, so comparing information can give you a clearer picture. Search for the key claim using specific words rather than simply searching for the entire headline. Look at reports from several credible and independent sources. For important information, do well to give greater weight to primary sources and organisations with relevant expertise. Peradventure, if you encounter a claim about a public health policy, look for information from the relevant health authority, and if the claim concerns examination results, check the examination body's official communication. If it concerns a court ruling, look for the actual judgment or credible reporting based on it. The aim here is not to find several websites repeating exactly the same sentence; the aim is to find independent evidence supporting the claim.
5. Separate Facts From Opinions
Not everything published online is intended to be a factual report [this is another all-too vital caveat everyone must understand]. An opinion article, personal blog post, commentary video, or social media post may contain legitimate arguments without being an objective presentation of facts, so pay attention to the language being used. Statements like “I believe," “in my opinion," or “this suggests” signal interpretation. Statements containing specific figures, dates, events, or quotations can be checked against evidence. Now, a useful question would be: What exactly is being claimed, and what evidence gives strong credence or authenticity to it? This prevents you from treating the interpretation of someone as an established fact.
6. Be Careful With Headlines
In today’s world and our society, where attention is a strong, subtle currency, headlines are mostly designed to attract/capture attention!
A headline can be technically connected to an article while still giving readers a misleading impression of what the article actually says, and this is a common feature with sensational or click-driven content. Do not fact-check a headline alone; read the article and identify the specific claim that is being made. Also be cautious when a headline uses words such as "shocking," "secret," “everyone is saying," “you won't believe," or “experts warn." Language of this sort does not automatically make information false, but it is a good reason to slow down and investigate further.
7. Verify Images and Videos
Images can be intentionally deceptive because people often assume that seeing something means they have evidence, which, of course, is a fallacy. An authentic photograph can be used with a false caption, while an old video can be presented as footage from a recent event.
We recommend reverse image searching as one way to investigate an image's previous appearances and determine whether it has been used in a different context.
When checking an image or video, ask:
- Where did it first appear?
- When was it created?
- Does the location match the claim?
- Has it appeared in older reports?
- Does the original caption say the same thing?
These questions can expose misleading posts surprisingly quickly.

8. Use Fact-Checking Websites and Tools
You do not always have to investigate a claim from scratch, as Google's Fact Check Explorer, for example, allows users to search for fact-checking articles from independent organisations. You can search using keywords or even a specific quotation. Finding a fact-check does not mean you should stop thinking critically. Read who conducted the fact-check, examine the evidence provided, and then check whether it actually addresses the claim you encountered.
9. Be Especially Careful With AI-Generated Information
Artificial intelligence has made it easier to produce convincing text, images, audio, and videos, and this creates another important reason to verify information rather than assuming that something is accurate simply because it is presented confidently.
AI tools can produce incorrect information, and Stanford's digital literacy guidance specifically recommends using lateral reading to fact-check information obtained from AI systems. If an AI tool gives you a statistic, quotation, study or historical claim, verify it independently before using it as evidence.
10. Do Not Share Information You Have Not Verified
Perhaps the most important step is also the simplest: pause before you share!
UNESCO identifies media and information literacy as an important skill for navigating the online environment and dealing with misinformation and disinformation. Its recent figures also indicate that many digital content creators do not systematically fact-check information before sharing it. You do not have to investigate every harmless social media post for hours, but claims involving health, money, politics, public safety, crime, education, or major breaking news certainly deserve extra attention (or scrutiny, if you’d see it that way).
If you cannot establish whether something is true, it is better to say “I cannot verify this” than to present an unverified claim as fact.
The Bottom Line
Fact-checking information online does not mean you become suspicious of everything you read; it just translates to becoming more deliberate about what you accept as true. Check the source. Find the original information. Check the date. Compare independent sources. Examine images and videos. Use reputable fact-checking tools. Be cautious with AI-generated information and, most importantly, pause before sharing.
The internet gives almost everyone the ability to publish information and that makes knowing how to verify information online just as important as knowing how to find it. Before you click “share”, take a moment to ask three pertinent questions: Who is behind this information? What evidence supports it? What do other reliable sources say? Without mincing words, sometimes, those few seconds can make the whole difference between spreading useful information and spreading misinformation.
