Most people trying to create a Wikipedia page make the same mistake. They think that having a company website, a lot of social media posts, or a few mentions online is enough to get a page. That thinking usually leads to disappointment.
In reality, when you send in a draft through AfC (Articles for Creation), editors don't care much about your website or your LinkedIn page. They look for Wikipedia's main rule: Verifiability. Without sources that other editors can find and read, your draft won't go anywhere, so knowing what counts as reliable sources for wikipedia decides if your page gets accepted or turned down.
Tip: Before checking your sources, it's helpful to see if your topic even qualifies for a page. Our Wikipedia Notability Guide explains who meets eligibility criteria and what editors look for.
Why Reliable Sources Matter on Wikipedia
Wikipedia verifiability means every fact in an article must come from a published source that readers can find and read themselves. When you put in a fact without proof, editors have no way to know if it is true or false. The reasons why reliable sources are a non-negotiable:
They Satisfy Wikipedia Notability Requirements
Having a reliable source means satisfying the GNG (General Notability Guideline) and SNGs (Subject-Specific Notability Guidelines) of wikipedia.
Ensure Trust Through Strong Policies
The wikipedia reliable sources policy sets clear rules that help keep a neutral point of view across millions of articles. Without these rules, Wikipedia would quickly become a collection of unchecked opinions rather than a trusted encyclopedia.
Good Sources Also Protect Your Work
They keep articles safe from fights over facts. When a page is built on strong proof, it is much less likely to be quickly deleted or get caught up in discussions where experienced editors argue about whether it should stay.

What Are Reliable Sources for Wikipedia
A reliable source in terms of wikipedia notability requirements means a source that satisfies the three filters of reliability: reputed editorial board, accuracy and independence. The wikipedia reliable sources guidelines give detailed help on rating sources, including lists of sources that Wikipedia editors have decided are not trustworthy and should be avoided completely during research.
The Three Characteristics of a Reliable Source Explained
When Wikipedia editors look at a source, they check for three specific characteristics. Knowing these will help you see why some sources are accepted while others are turned down.
1. Editorial Oversight
The first thing editors check is whether a publication has editorial oversight. This just means that content is checked by someone other than the writer before it gets published.
Think of it like this. When a newspaper runs a story, it goes through fact-checkers, copy editors, and section editors. This multi-step review process finds errors and makes sure someone is responsible. If a publication puts out corrections or takes back stories when errors are found, it shows they care about getting facts right.
Publications with strong editorial oversight typically have:
- A list of their top editors
- Clear rules for sending in work
- Clear policies on fixing mistakes
Tip: Understanding editorial standards also helps if you’re following our How to Create a Wikipedia Page guide, since it explains how to structure drafts that meet Wikipedia’s expectations.
2. Reputation for Accuracy
Beyond basic oversight, Wikipedia looks at a source's history of getting things right. A source with a strong history of accuracy has built trust over time through steady, reliable reporting.
For news publications, this means following standard practices in journalism and having a strong record for checking facts. For academic work, it means going through peer review and appearing in journals with good standing in their field. You will notice that well-known schools and groups often have good reputations that make their publications more believable.
The key point here is that reputation is not built overnight. Sources earn trust through:
- Years of accurate reporting
- Clear fixes when they make mistakes
- Proven knowledge in their field
When an article has a writer's name from a known expert or appears in a publication with a long history of getting things right, wikipedia editors take it as a positive sign.
3. Independence
The third thing might be the most important, and it is also the most misunderstood: Independence.
This means the source has no connection to the person or topic being written about.
Wikipedia requires independent sources precisely because they offer distance from the subject. For example, when a company writes about itself, it has every reason to look good. But when an independent journalist writes about that same company, they can report more fairly. This reporting from a distance is exactly what editors look for.
Independent sources wikipedia also means:
- No money ties
- No goal to promote something
- No personal stake in the topic
Types of Reliable Sources Wikipedia Typically Accepts
Now that you know what makes a source reliable, let's look at the specific types of publications that give your article the strongest possible base. Each wikipedia citation should ideally come from these groups.
News Publications
Well-known newspapers and magazines form the backbone of most Wikipedia articles. When editors see a writer's name from a known journalist and a publication with a clear list of its top editors, they immediately feel more sure about the content.
What makes news publications trustworthy:
- A formal group of top editors that watches over what they cover
- Standard newsroom practices for checking facts
- Public statements explaining what went wrong when mistakes happen
You might also notice that many news organizations use news services like the Associated Press or Reuters. These services provide reporting to hundreds of outlets, and their stories go through careful checking before being sent out. When you see "AP" at the beginning of an article, that signals an extra layer of trust.
Academic Journals and Scholarly Research
For topics related to science, medicine, history, or any academic field, research from experts carries the most weight. These sources go through peer review, which means other experts in the field check every part before it is published.
You can find credible academic journals by checking whether they appear in well-known databases that list academic work like:
These databases only include journals that meet specific quality standards. Also, good research articles will include clear sections explaining how the study was done, letting other researchers check their work.
In addition to the database, pay attention to citation count: how many times a study is mentioned by others. When many researchers refer to a study, it suggests the findings have made a difference in their field. For Wikipedia purposes, articles that sum up many studies often prove more useful than single experiments.
Books from Established Publishers
Books offer something that shorter publications cannot: deep, thorough coverage of a topic. When a book has an ISBN and comes from a known publisher, it signals that someone put money into the project and believed in its quality.
Pay attention to the publisher name:
- Books from university publishers (Oxford, Cambridge) go through careful academic checking
- Publishers that focus on academic work follow similar standards
- Mainstream book publishers can work well when written by qualified authors
Flip to the copyright page and check how many times it has been printed. Many printings suggest the book has found readers and stayed useful over time.
Industry and Trade Publications
Some topics, particularly in business, technology, and entertainment, get their best coverage in publications focused on that field. These trade magazine sources sit somewhere between news and academic writing.
The key with trade publications lies in checking their independence. A trusted publication in a specific industry:
- Keeps a clear line between advertising and news content
- Many of these publications come from professional groups
- Serves their members by giving fair information about the field
Medical and Science topics require extra care here. For medical and science content, Wikipedia editors strongly prefer the strongest research that combines the results of many studies published in trusted journals over trade publications. This is because the risks with this information are simply too high for anything less than the best proof.
Sources That Usually Do NOT Qualify
Most new contributors simply do not grasp the concept of reliable sources for wikipedia, which explains why drafts fail so consistently. This is the reason why non-compliant sources appear constantly in rejected submissions, and so Wikipedia editors maintain strict standards about what cannot be used.
The following are routinely disqualified:
- Personal blogs with anonymous authorship and no review process
- Corporate communications from official websites and about us pages
- Press releases distributed through distribution services with standard text that gets sent everywhere
- User-generated content across social media platforms
- Vanity press titles and print-on-demand books where the author pays to have their work published
- Advertorials and native advertising labeled as sponsored content
- Sales decks and promotional materials
Quick Reference: Why Each Source Type Fails
| Source Type | Primary Failure | Secondary Failure | Editor's Mental Note | |
|---|---|---|---|---|
| Personal blogs | No one knows who wrote it and no one checked the work | Writer lacks deep knowledge of the topic | "Just some person's opinion" | |
| Corporate communications | Not independent from the topic | Tries to sell something throughout | "They're selling something" | |
| Press releases | Written by the topic itself | Sent out, not investigated by reporters | "This is just an ad" | |
| User-generated content | Claims not checked for truth | Could be taken down at any time | "Could disappear tomorrow" | |
| Vanity press titles | No one checked if it was true before publishing | Writer paid to get it published | "No one fact-checked this" | |
| Advertorials | Paid ad that looks like real news | Label says it's sponsored | "Someone paid for this" | |
| Sales decks | Main goal is to convince you | Leaves out bad information on purpose | "This is just marketing" | |
The bottom line: If the subject controls, pays for, or creates the content themselves, it cannot serve as a reliable source for Wikipedia. This shows again that Wikipedia requires every source to pass the independence test.
Common Sourcing Mistakes That Lead to Rejection
Even experienced creators make mistakes with source selection, and these common errors almost always lead to rejection.
- Relying only on company websites. Company sites work as primary sources, which means they give firsthand information without the independent neutral proof Wikipedia requires.
- Using press releases as primary sources. Distribution services make it look like real coverage, but this practice of just reprinting press releases with no original reporting just repeats ads and has no fact-checking.
- Citing small blogs without standards. Personal sites lack editor oversight and fact-checking, making them unreliable for any kind of truth-checking.
- Including sponsored content. Native advertising looks like journalism, yet it lacks true independence. Wikipedia requires content free from any goal to sell something.
- Sources with only passing mentions. Just naming the topic within longer articles does not count as deep coverage, so editors need sources that explore topics in depth rather than just listing them.
These errors show a basic misunderstanding of wikipedia reliable sources requirements, and each mistake shows that the creator skipped basic checking of sources during preparation.
Conclusion: Reliable Sources Form the Foundation
Think of your sources as the foundation that holds up every claim you make. Weak foundations bring a risk of deletion and wasted work, so before writing, check your sources carefully.
Look at each citation against the three tests of editorial oversight, reputation for accuracy, and independence, then ask whether your topic has attracted enough external writing to meet community rules.
If the sources do not exist yet, neither should the article. These three tests form the foundation of wikipedia sources guidelines. When you understand them, you start to see why Wikipedia asks for what it does.
FAQ Section
What makes a source reliable on Wikipedia?
Reliable sources show a strong history of editorial supervision, publish trustworthy information, and meet the standards required for Wikipedia publishing, including independence and neutrality.
Are company websites considered reliable sources?
For basic facts like when a company started, using the company as a source may be allowed in some cases. But company sites cannot satisfy wikipedia notability or back up claims that need independent verification from external sources.
Can social media be cited on Wikipedia?
Almost never. Accounts that are verified may work as primary sources for statements about what the account owner did themselves, but social media never counts as independent coverage for broader claims.
Can I use Wikipedia as an academic source?
No. Wikipedia articles risk creating a loop where students cite Wikipedia, which then cites sources later summed up in Wikipedia. They should always trace information back to original publications for proper credit.
What are reliable sources for Wikipedia?
This depends on the topic you choose. Examples include news publications, academic journals, established books, and trusted trade sources. For pages about living people, the rules are even stricter because living people need stronger sources than historical figures.
