Viral posts can mix genuine information with old images, missing context or entirely false claims. This reusable checklist shows how to verify a social media post, headline, image, video or forwarded message before you share it or act on it.
Overview
Fact-checking does not always require specialist software or hours of research. The most useful first step is to slow down and separate the claim from the reaction it is designed to create. Ask exactly what the post is saying, when the alleged event happened, where it happened and what evidence is offered.
A post may be misleading even when part of it is true. A real photograph can be paired with the wrong date; an accurate statistic can be used without its definition; and a genuine announcement can be presented as a new development months after it was issued. Treat the post as a claim to investigate, not as a source that has already proved itself.
Use this basic order:
- Pause: do not share, pay, travel, contact someone or make a personal decision solely because a post feels urgent.
- Capture: save the link, account name, wording, date and any images before the post changes or disappears.
- Break it down: identify the specific factual claims that can be checked.
- Find independent evidence: look for primary sources and reputable reporting that are separate from the original post.
- Decide what is justified: label the claim as supported, false, misleading, unproven or still developing.
For UK local news, primary sources may include a council, police force, court, transport operator, health service, school or government department. For international stories, look for statements from relevant institutions and reporting from established outlets with transparent corrections policies. A search result or a large number of reposts is not, by itself, confirmation.
Checklist by scenario
For a breaking news headline
- Read beyond the headline and check the publication date and update time.
- Search the key terms in a new tab rather than relying only on a screenshot or repost.
- Check whether multiple independent outlets are reporting the same event, and whether they are citing the same original source.
- Look for an official confirmation where appropriate. During an unfolding incident, absence of confirmation does not prove a claim false, but it should make you cautious.
- Check the location carefully. Similar place names, recycled local stories and reports from another country can create confusion.

For a photograph or graphic
- Run the image through a reverse-image search using an available search engine or visual-search tool.
- Compare earlier results to identify the original location, event and date.
- Inspect signs, weather, road markings, uniforms and architecture for clues, but do not treat visual impressions as proof.
- Check whether the image has been cropped, mirrored, edited or combined with a different caption.
A reverse-image search may not find every manipulated or newly published image. Use it as a lead-finding tool, then confirm the result with reliable sources.
For a video or audio clip
- Find the earliest available upload and note who posted it.
- Check whether the clip is complete or edited. Missing before-and-after context can change its meaning.
- Search distinctive phrases, signs or landmarks from the footage.
- Be careful with subtitles, translations and dubbed audio. They may not accurately represent the original.
- Do not assume clear audio or realistic facial movement proves authenticity. Synthetic and altered media can be difficult to identify by sight alone.
For a claim about money, benefits, health or public services
- Identify who is affected, where and from what date.
- Check the relevant official department, council, regulator, health body or service provider.
- Read the eligibility rules, definitions and exclusions rather than relying on a summary post.
- Distinguish a proposal, consultation, announcement and law or implemented change.
- Do not enter bank details or pay a fee through a link in a viral post until the organisation and web address have been verified.
Newslive explainers on benefits and cost-of-living changes, NHS services and council decisions provide useful context for checking claims in these areas.
What to double-check
The source: Is the account identifiable? Does it link to an original document? Has it corrected mistakes before? A blue tick, high follower count or familiar logo is not a substitute for evidence.
The date: Search the wording in quotation marks and look for older versions. A genuine story from a previous emergency, election or weather event may be recirculated as if it happened today.
The numbers: Check what is being counted, the time period, the population covered and whether the figure is a total, percentage, estimate or forecast. For economic and policy claims, our guide to reading inflation and interest-rate updates explains why definitions matter.
The wording: Watch for absolutes such as “everyone”, “banned”, “confirmed” or “no one”. Ask whether the evidence supports that strength of language.
The original document: If a screenshot shows a letter, chart or announcement, search for the document on the issuing organisation’s own website. Check the full page, not only a cropped extract.
The verdict: A fact-check should explain its reasoning and link to evidence. Full Fact, BBC Reality Check and Reuters Fact Check are examples of organisations readers may consult, alongside the relevant primary source. Their findings should still be read in context, particularly when an event is developing.
Common mistakes
- Checking only information that agrees with you: apply the same standard to claims you support and claims you dislike.
- Confusing repetition with corroboration: ten accounts may simply be copying one unverified post.
- Using a search snippet as evidence: snippets can be incomplete, outdated or detached from the article’s conclusion.
- Overstating the result: “not proven” is not always the same as “false”. Use a precise label.
- Sharing to ask whether it is true: reposting can increase the claim’s reach. Share the correction or a neutral question without amplifying harmful material where possible.
- Ignoring personal safety: do not confront suspected individuals, publish private information or visit a location to investigate a viral claim.
If a post appears fraudulent, threatening or designed to collect personal details, use the platform’s reporting function and, where relevant, contact the appropriate organisation through a verified channel. Keep a record of the URL and screenshots, but avoid forwarding the material unnecessarily.
When to revisit
Recheck a claim whenever new evidence appears, an official body issues a statement, a platform changes its labels or reporting process, or the post begins circulating in a new form. This is especially important during elections, severe weather, public-health events, major court cases, market shocks and emergencies, when early information can change quickly.
Before seasonal planning periods, review bookmarks for official council, transport, weather, school and health-service pages. Tools for reverse-image searching, web archives and platform reporting can change, so confirm that your saved links still work. Fact-checking organisations may also update their methods and published guidance.
Keep this short version handy:
- What exactly is being claimed?
- Who first published it, and when?
- What is the original evidence?
- Can an independent primary source confirm it?
- Is the image, video, number or quotation being used in the right context?
- What remains unknown?
- Would sharing it create avoidable harm?
If you cannot answer these questions, do not share the claim as fact. Save it, check it again later and use a cautious description such as “unverified” when that is the most accurate conclusion.
