Writer’s guidelines

For clarification, the company Petri Pixel MB:98047078 represents Curiosmos.com

This document is a “how to start” writing guide that aims to showcase what articles we publish at curiosmos.com and what type of content will get published as well as the rights associated to the article once accepted for publication and purchased by Petri Pixel.

This document is compiled to get you started and understand what the audience reading curiosmos.com enjoys.

The guide aims to help future authors better understand the types of articles we publish and how we convey a message to our readers.

Although this guide is just that—a guide—and must not be followed strictly, the more you adhere to what is written in it, the more likely your content will be accepted for publication.

Prerequisites for a successful submission on Curiosmos

For your article to appear on Curiosmos, the submission must meet a few requirements. If the article does not meet these, it will likely be rejected and not published.

  1. The content must be written in PERFECT ENGLISH. Your written English must be close to that—or that—of a native speaker. The number one reason why content may be rejected for publication is due to poor English. Over 80% of our readers are native English readers.
  2. Proof and verifiable. When writing content, these are two things you need to adhere to and keep in mind. If you are unable to source and provide proof from REPUTABLE sources, the content will not be published.
  3. Original. The subject you are writing about must not have been previously published on Curiosmos or anywhere else on the internet. Curiosmos will not accept submissions that are rewritten articles, blog pots, or content scraped from elsewhere. We will not accept content that has been scrapped from videos such as VIMEOor YouTube. Before publishing, make sure to check com if we have covered it in the past.
  4. Equally important: you cannot publish content that has been translated from another language. The content must be 100 % written by you and original.
  5. Curiosmos is a place for the curious mind. This means that to publish on the site, you need to adhere to our writing style. We do not accept content related to sports, politics, advice, or similar subjects. We do not accept adult-related content, and we do not accept articles that promote or assist others in committing a crime.
  6. We take plagiarism very seriously. If the content you are submitting for publication is plagiarised or is an attempt to promote someone else’s work as yours, you will not be accepted for publication. You will not have the ability to publish your work on our websites in the future. We use a series of tools to check each article for plagiarism.
  7. We do not accept content that is written by organizations or “content middlemen.” Content from third parties that supply content is not accepted.


The type of content

As mentioned in the “prerequisites for a successful submission,” certain types of content will not be accepted for publication, and that includes Adult content or content that promotes violence or crime.

Curiosmos is an independent website, and as such, we are entirely apolitical and want to remain as such. This means that content about politics, related to politics, or promoting politics will not be accepted for publication.

The content you are submitting for publication must be between 1,500 and 2,000 words without taking into consideration the length of the sources. Form time to time we might accept content that is 1,000 words long. Having that said, longer content will generally perform better and is preferred.

The best content is that which is written with a special plot—a twist if you will. Take into consideration that content that is easily digestible will most be appreciated by the reader. Make sure to convey your message in a simple but interesting manner.

To get a better idea of what we are looking for please read below.

Unique content is content that matters

Below we will give a series of examples that are meant to serve as guidelines to the type of content that does well on the website and the type of content that our readers usually enjoy. The most important thing when submitting an article for publication is that it is unique from head to toe.

To maintain an active readership—Curiosmos receives around 2 Million page views per month—we need content that provides new, verifiable, and unique information. That’s why our content must always be unique. Content that is not unique will not be published on Curiosmos. Remember, unique content attracts readers and has them coming back for more. That’s your goal.

Content that keeps our readers returning and engaged

Great and unique content is content that is widely appreciated by our readers. For content to be appreciated by the millions of people reading us on a monthly basis, it must be unique, interesting, and keep the reader engaged. The content we appreciate is that which teaches and offers new insight into a variety of subjects. This type of content will keep our readers engaged and will see them return for more.

Clearness of Text

The simpler an article is, the easier to understand it will be. We understand that some of the subjects on the site are challenging to understand which is why we strive for content that offers “clearness of text” or that is in other words simple to understand. To get a better idea of what we mean by this, an article you write should be understandable by an 11-year-old child. Not because the text is dumped down, but because some of the best articles on the site are those written with clear, simple text. To achieve this, we use a tool called Flesch-Kincaid index. You can check how readable content is by visiting this link: https://www.webfx.com/tools/read-able/flesch-kincaid.html

The content our readers enjoy

Since Curiosmos covers a particular niche of subjects, our readers have a particular taste when it comes down to what they enjoy reading about on Curiosmos. In order for your content to be accepted for publication, you should try and adhere to the content people love on the website.

Here is a list of some of the most popular categories on Curiosmos:

1) History

Our readers love history and everything related to it. Many of our most-read articles are directly related to history, archeology, and anthropology. Subjects that are in general history-related tend to well on the site. An example of great articles would be 12 Astounding Images From the Inside of the Great Pyramid You Should SeeOlder Than History: 3 Ancient Cities That Predate Pyramids by Around 5,000 Years.

2) Mystery

This is one of our most popular categories. Here, you will have the opportunity to write about unsolved mysteries in history, the Cosmos, our origins. This category includes UFOs, Alien Life, and the supernatural in general. The category needs content that is not widely covered by the rest of the world wide web. This means that content about the Bermuda Triangle, the Loch Ness monster, or similar popular “myths” are some examples of what we avoid writing about on a larger scale. Some examples of what we like; https://curiosmos.com/unwritten-mystery-what-was-hidden-in-the-submerged-osiris-shaft-in-egypt/; https://curiosmos.com/unwritten-mystery-the-alleged-ufo-incident-near-aztec-new-mexico-known-as-the-other-roswell/; https://curiosmos.com/the-worlds-first-ufo-recorded-780000-years-ago/

3) Space

Exploring the universe is what we love to do. The Cosmos is there for the taking, and content related to space, exploration, and the universe, in general, is very appreciated by our readers. The content that falls into this category should not be of the “news” type but written with a “curious mind.” A few examples: https://curiosmos.com/nasa-publishes-never-before-seen-images-of-the-apollo-11-mission/; https://curiosmos.com/heres-are-4-stunning-close-up-image-of-an-asteroid-300-million-kilometers-away/; https://curiosmos.com/hopes-of-alien-life-on-mars-increase-after-new-satellite-images-reveal-network-of-hidden-lakes/; https://curiosmos.com/cosmic-perspective-50-images-that-will-make-your-reconsider-your-existence/


In addition to these categories—specific subjects— you can write about the following content that in this case is generalized but related to the following:

1) Secrets

Secrets of the universe. Secrets of history. Secrets of humanity. This allows you to cover a plethora of subjects that the average person will probably not know about. Here are some examples: https://curiosmos.com/5-untold-secrets-you-probably-didnt-know-about-the-vaticans-necropolishere-are-5-untold-secrets-about-the-vaticans-necropolis/; https://curiosmos.com/8-secrets-you-didnt-know-about-ancient-city-of-petra/; https://curiosmos.com/here-are-10-secrets-and-curiosities-about-the-great-sphinx-of-egypt/

2) Lists

Lists are always popular on the site. Whether you are writing about ten cool places to visit besides the pyramids in Egypt or 10 Facts you didn’t know about the Great Pyramid, lists on Curiosmos are always welcomed by our readers. Here are some examples; https://curiosmos.com/10-things-you-should-know-about-cholakova-mound-bulgarias-forgotten-stonehenge/; https://curiosmos.com/10-things-you-probably-didnt-know-about-the-vaticans-spectacular-bramante-staircase/; https://curiosmos.com/here-are-5-things-you-should-know-about-the-worlds-oldest-sword/

3) Facts

Although still presented in the form of lists, the Facts section on Curiosmos is unique because it describes the content that we probably have heard about before, but not in an in-depth manner. 10 Facts about Egypt’s Pyramids is one example, but this can also be presented as in 10 misconceptions about the Great Pyramid of Giza. Here are a few examples: https://curiosmos.com/10-curious-facts-about-the-pyramids-of-tenerife/https://curiosmos.com/10-facts-about-the-quinametzin-the-giants-of-aztec-mythology/https://curiosmos.com/10-facts-about-ingenuity-the-first-helicopter-on-mars/https://curiosmos.com/10-most-fascinating-cursed-artefacts-of-all-time/.


In addition to the above, please bear in mind the following:
