Evaluating web resources is a challenging part of research. In times when anyone can put information on the internet, you can’t tell whether a website is scientific or not from just the first glance.

So, how is it possible to distinguish credible sources from hoax websites without spending days doing it?

We’ll show you the fastest way to estimate your sources—several tips that can be applied to any kind of website. You will also get a list of credible news sources and science blogs. At the end of the article, we’ll demonstrate how to apply a website evaluation checklist and use it for a website reliability check.

1.  🌐  What Are Unreliable Websites?

Today there is simply too much information online. Every website tries to become more popular and increase its number of readers. And not every site uses honest ways to achieve this respect.

What’s more:

A lot of books, articles, and films are full of obscurantism—the intentional hiding of information. So knowing what is credible and what is not is essential even if you aren’t taking part in scientific research.

And things get even more challenging when you need to do a source evaluation for academic writing. You can’t just use a list of credible sources—there are too few of them to develop a great work of research. What you need instead is a solution to the problem: how to know if the website is legit.

We’re ready to give it to you.

2.  🔒  Internet Information You Can Trust

Reputable online sources aren’t necessarily only boring websites developed in 2010 that use unattractive fonts and dizzying colors—even though good web design is one of the features of trusted sources.

Reliable sources can also be selling something. It’s wrong to think that scientific websites should always be run by volunteers.

But if we can’t rely on web design or a site’s motivation, what else can we use to evaluate websites?

There are many strategies to find good internet sources. Some students use trusted search engines, while others search for certain authors—for example, professors from their university.

There’s also a trick you can try when using the Google search engine that provides access to academic information for research:

  1. Type in whatever you’re searching for, like “divorce statistics” or “horse behavior investigation.”
  2. Add “inurl:.edu” or “inurl:.gov” to your search term.
  3. Enjoy the scientifically proven facts!

Of course, you can’t always put such limitations in place when working on research or report writing. That’s why we’ll teach you how to check websites’ reliability using the smallest of details.

But, first, we’ve prepared some credible websites in different categories for those who are in a hurry. You can always use our list of credible resources to find the newest information in politics, science, or economics.

3.  🔎  A List of Trusted Search Engines

There are several ways to solve the issue of how to evaluate internet sources. One of them is to find academic sources with search engines developed specifically for students and professors.

Here are some examples of good search engines for research papers. Use them for your studies whenever you’re working on an essay or dissertation.

3.1.  Credible Sources for Students

This is a short catalog of the authoritative and trusted university, government, and non-commercial websites for research on any topic in hundreds of spheres.

With these engines, you won’t have to worry about knowing how to tell if a source is credible. Just type in the information you need to find, and get a list of credible websites.

3.2.  Credible Science Sources

Everyone involved in scientific research is aware of the existence of non-credible resources. For scientific research, it’s especially critical to be accurate and use proven facts and statistics.

These search engines will give you access to credible science sources.

4.  📰  A List of Credible News Sources

Of course, journalism isn’t exactly comparable to scientific writing. No matter how hard you try to describe world news, politics, or economics, thousands of people will find your article subjective.

But still, there are some less credible and more credible news sources. We’ve gathered here a number of news websites in which the main purpose is to give information about what’s happening in the world—not to share a certain point of view.

6.  ✅  Website Reliability Check

The links we listed above are great for fast access to trusted information. But one necessary skill of every student is knowing how to perform an independent critical evaluation of web resources.

It’s true for books, surveys, journals, publications, and, of course, websites—which are often the most difficult type of source to estimate.

So if you’re wondering how to evaluate internet resources, check for these main signs of source credibility:

  1. It has an author.
    Expedition 51 European Space Agency
    Crew Researches Bone Loss, New Exercises and Emergency Training, NASA

    Scholarly sources always note their authors. You can type the writer’s name in Google and find out more about them.

    Ask yourself the following questions:

    Are these authors famous in the scientific world? In what fields do they work? What topics do they investigate?

    When evaluating information resources, it’s important to make sure the writer is qualified enough to give such information.

    The next step is to look for contact information. Anyone should be able to connect with the writer. Search for a personal or professional email address or social media links.

    If the page you’re evaluating is a scientific one, make sure the author has a relevant degree or is attaching his studies to a university.

    Keep in mind that sometimes the writer of a blog article won’t be directly involved with any scientific inventions—but if the website is revised by a specialist, it’s still a trusted resource.

  1. It provides current information.

    You don’t want to use outdated sources, do you?

    That’s why it’s important to check whether the credible evidence is new or was posted years ago.

    When evaluating a resource, it is important to consider that the date of the article doesn’t mean it was originally posted on that day. Look for the original article on the internet—you can, for example, copy part of the text and put it in your favorite search engine.

    Original site search in google

    In the example, the text is found only on the website that published the original article.

    Try to find where the author posted it in the first place. Many writers have Twitter accounts or personal blogs to announce their publications and investigations.

    Make sure also that the information is revised from time to time. You can check for this by looking out for a note that says “updated.” It often appears at the top of the article.

    Also, pay attention to the comments—does the author reply to them? Is it obvious from the comments whether the materials are revised or not?

  1. It pays attention to its links.

    When a reputable source shares facts, statistics, or the results of surveys/investigations, it supports them with relevant web links.

    Make sure that the articles you use aren’t giving statistics without links. They can be included in the text or follow the article at the bottom of the page.

    Example: The Guardian links to a video to prove the information it describes.
    House Republicans plan Thursday vote on bill to repeal and replace Obamacare, The Guardian

    In this example, The Guardian links to a video to prove the information it describes.

    If there are links, note what are academic sources that prove the facts. They must be scholarly databases or news from universities. If the source is a study, read the abstract carefully. You can find the most significant information there.

    Then, note whether there are any broken links. Authoritative websites tend to fix them as quickly as possible. If the page is full of 404 links, there’s a big chance that it’s a non-credible resource.

  2. Its purpose is to inform.

    There are many possible motivations for having a blog. A reliable website could be written by a professor whose goal is to sell more books, while a hoax website may confuse its readers trying to gain popularity.

    When evaluating online resources, try to uncover the primary aim of the writer. Is it persuasion, information, or personal profit?

    Discovery is a great example of an informative source:

    Discovery is an example of an informative source:

    Notice the manner of writing. If the writer is trying to convince you or put a specific idea into your head—be careful with the information the article offers.

    There are also many websites that are selling something—for example, a course. They may claim that 100% of their graduates get a prospective job, escape divorce, play ukulele like a pro, or something like that. You can safely bet that such articles aren’t examples of credible sources, and adding their data to an academic paper isn’t a great idea.

  3. It’s grammatically correct.

    Check the article for spelling mistakes. The most common misspellings are:

    • a single consonant instead of double (for example, in the words finally and apparently)
    • -ei instead of –ie (for example, in the words foreign and lie)
    • -ant instead of –ent (for example, in the words coefficient and accent)
    • -w instead of –wh (for example, in the words when and whine)
    • -per instead of –par (for example, in the words parasite and separate)
    • -ence instead of –ance (for example, in the words radiance and relevance)
    If there are too many misspellings, how could we even consider the presence of reliable statistics and facts?

    Also, look for the most common grammar mistakes. For example:

    • Its instead of it’s
    • Subject-verb agreement
    • Apostrophes instead of the plural form
    • Fewer instead of less
    • To instead of too
    • Then instead of that
    According to Grammarly, a recent Popular Science article has a score of 100. That means there are no misspellings, grammar, or punctuation mistakes.

    And don’t forget about the structure of the text as well as individual sentences, including punctuation. On Custom-Writing.org, you can find a global guide on punctuation. Use it to check a couple of sentences when you’re evaluating web resources.

  1. It isn’t isolated from the world.

    If the information from a page is useful to the scientific world, it should leave some traces around the internet.

    Search for other publications that have used the article as a source of statistical data or surveys, or look for citations in journals and university blogs.

    These are some citations of The Economist on the internet:

    As you can see, its information is used in many professional books and on academic websites.

    Do quality research into scientific websites to find information about the writer of the article.

    It isn’t any less important for a credible article to have a meaningful bibliography. Get familiar with the sources it offers.

    Pay attention to images as well. If they are included in an article, they should be original or offer information about the source.

These tips for evaluating resources are useful to apply whether you’re doing research for academic writing or reading a blog for self-development. To make this task easier, we’ve created a helpful questionnaire. You can download it or use it online for a fast website credibility check.

✏️  Credible Sources FAQ

What definitely makes a website credible is .edu or .gov in the URL code. You may add “inurl:.edu” or “inurl:.gov” to your Google search. If a website is not updated, the content is not structured, the texts contain grammatical and formatting mistakes – that source is probably not reliable.
Any website that contains .edu or .gov in the URL code would serve as an example of a credible online source. Other relatively reliable sources include famous online dictionaries and encyclopedias. However, beware of unreliable copies of such websites with a similar title or design.
It is usually possible to tell if the source is credible relying on common sense. For example, if there are formatting and grammatical mistakes, the content is not structured, the pages do not load properly, and the website is not updated, it is probably unreliable.
To determine that an online source might not be credible, pay attention to details. Does the site look neat and structured? Are there mistakes in grammar or formatting? Do the pages load properly? Does it have huge ad banners that hinder the website usage?
