Readability is measured by two main methods: Reading Ease and Grade Levels.
Comprehensibility forms with Lexical Density the third pillar of text analytics.
Measures textual difficulty, which indicates how easy a text is to read. The defacto standard here is the Flesch reading-ease. Higher scores indicate that it’s easier to read; lower numbers that it’s more difficult. If you want to reach the biggest audience possible with your writings, you should design your text to score high on this.
|90–100||Understood by a student +12 y/o|
|60–70||A High school graduate can understand this.|
|0–30||Comprehensible to someone with a university degree.|
Summary: The higher the reading ease, the more people will understand your text.
Refers to the years of education required (starting from 1st grade) to be able to comprehend a text. There are multiple accurate and sophisticated mathematical models in existence. For sake of simplicity CheckText.org recommends the Average Grade Level. That is a median of the Top 5 Grade Levels (Flesch-Kincaid Grade Level, Gunning Fog Index, Coleman-Liau Index, SMOG and Automated Readability Index).
|6||Kids and teenager|
Summary: The lower the grade level, the more people will understand your text.
In addition to readability exists comprehensibility: The likelihood that educated people will be able to understand a text about a topic prior unknown to them. This is done by Lexical Density. It measures the ratio of content words to grammatical words. Content words are most important for explaining information. If you have a high number of content words, you’ve most likely written a specialized academic text which will only be understood by people in that field. If you have a low number of content words, you have a very simple, easy-to-understand piece.
|60%||Bachelors / Master thesis|
Summary: The lower the lexical density, the more people will comprehend your text.
Search Engine (SEO)
For an article to rank good within a search engine, you have to fullfill a couple of technical minimum criteria. These are majorly defined by a mix of reading ease, keyword density and text length. For a good search engine visibility, your article should at least have 300 words, a reading ease of >80 and a keyword density of below 3%.
|Top 10||Professional and relevant article|
|Top 50||Average article|
|Top 100||Badly written and/or spinned content|
Summary: The lower your "Top", the more likely you will rank high with your text in search engines.
The unified definition of plagiarism has three criteria that all need to match:
(2) without appropriately acknowledging the source
(3) to benefit [in a setting where originality is expected].
The most common forms of plagiarism are:
|Inaccurately citing the source.||51%|
|Interweaving various sources together without citing.||43%|
|Using quotations, but not citing the source.||26%|
|Proper citations, but failing to change structure/wording of the ideas.||21%|
|Melding cited and uncited sections of the piece.||17%|
|Citing some, but not all passages that should be cited.||12%|
|Re-writing someone’s work without properly citing sources.||11%|
|Taking passages from own previous work without adding citations.||8%|
|Submitting someone’s work as own.||2%|
Summary: Most cases of plagiarism can be prevented by employing proper citation.
