How to check if a source is reliable before you share it online

Every day we scroll past headlines, videos and screenshots that ask for our attention and our trust. It takes only a second to tap “share”, but the signal we send can shape what friends, family and colleagues believe.

Learning a simple way to check sources is one of the most useful digital skills today. It helps you avoid spreading false claims, protect people you care about and feel more confident when information is confusing or emotional.

Start with a pause, not a share

Most misleading content works by pushing you to react quickly: anger, fear, outrage or excitement. A short pause is your first defence. If something makes you think “everyone must see this now”, that is a sign to slow down, not speed up.

Ask yourself: who benefits if I share this and it turns out to be wrong? You, your community, or someone who wants clicks, attention or political advantage? That small question creates space for more careful thinking.

Look at the source, not just the content

Many posts are screenshots, cropped images or reposted clips with no clear origin. Before you believe or share, try to answer a basic question: where did this come from originally?

Follow any links back to a homepage or profile. If the source is hidden, vague or constantly changing its name, that is a warning sign. Reliable sources usually do not hide their identity or contact details.

Check the name and “about” page

If the source is a website or blog, look for an “About”, “Contact” or “Who we are” section. You should be able to see who runs it, where they are based and what their purpose is. Educational institutions, established newsrooms and professional organisations are usually clear about this.

Be careful with sites whose names imitate well known outlets but with small changes, for example an extra word or unusual domain ending. Similar logos and colours do not guarantee similar standards.

Search around the source, not only within it

Do a quick web search of the site or account name together with words like “review”, “criticism” or “about”. See how others describe it. If you only find results from the same site or its close partners, you have a limited view.

Independent descriptions from media literacy organisations, academic projects or established news outlets can provide useful context. If you find many reports about hoaxes, plagiarism or undisclosed political funding, treat the content with caution.

Scan for basic quality signals

Quality signals are not perfect, but together they form a useful picture. Ask yourself a few simple questions when you open a page or profile:

• Are dates clear?Reliable information shows when it was published or updated, especially for fast changing topics like health or policy.
• Is the language careful?Lots of capital letters, insults, vague accusations and emotional language can signal more heat than light.
• Are sources named?Phrases like “experts say” or “it is known” without names, links or documents are weak support.
• Is there a way to correct errors?Corrections pages or notes show at least some commitment to accuracy.

No single signal proves that information is solid, but the absence of all of them should make you wary.

Trace claims back to primary material

Strong information lets you see where it came from. If an article mentions a study, report or court decision, there should be enough detail to find the original: a title, organisation name, date or document number.

When accuracy matters, click through and compare the original with how it is described. Look for differences in numbers, missing context or conclusions that sound much stronger in the summary than in the source itself.

Compare how multiple sources cover the same thing

Instead of asking “do I like this source?”, ask “how does this source compare to others on the same issue?”. Search for the main claim or event and open results from different types of outlets, including ones with various editorial perspectives.

If only one obscure site or anonymous account talks about a dramatic claim, while established outlets ignore it or contradict it, that does not automatically make it false, but it should make you cautious and less eager to share.

Be extra careful with images and short clips

Pictures and brief videos feel convincing, but they are easy to take out of context. A genuine photo from one place and year can be reused to illustrate a completely different situation.

Look for clues inside the image or video: number plates, signs, weather, clothing styles or languages. If something feels off, search a few key details together or use a reverse image search tool to see where and when it previously appeared.

Notice your own emotions and biases

We are more likely to believe and share information that fits our existing views or fears. That is human and unavoidable, but you can learn to notice it. Ask: would I question this more if it supported the opposite side of a debate?

If a post makes you feel superior to others or confirms that “only people like us see the truth”, take a step back. Reliable knowledge usually allows for nuance, uncertainty and complexity, not simple heroes and villains.

Adopt a simple sharing rule

You do not need to investigate every meme or comment. Focus on items that contain strong accusations, health or safety advice, political claims or financial guidance. These can affect real decisions and deserve a higher standard.

A helpful rule is: “If I do not have time to check it, I do not have time to share it.” Silence is sometimes the most responsible digital action, especially when something cannot be verified quickly.

Make careful checking a normal habit

No method is perfect and even careful people can make mistakes. What matters is the habit of pausing, checking and being willing to correct yourself. When you learn something new that changes your view, sharing that correction is also a form of digital responsibility.

Over time, small personal habits can shape the wider information environment. Each careful share tells platforms and publishers that quality still matters more than speed.
