What Is a Readability Score?
The term readability refers to the ease with which a user can understand a written text. A readability score is between 1 to 100 used to identify how easy or difficult it is to read or understand a written text.
How To Calculate Readability Score?
The calculation of the readability score is based on the Flesch-Kincaid test of readability. There are two tests available for calculating readability. One is Flesch Reading-Ease and the Flesch-Kincaid Grade Level. Although they use the same core measures i.e., word length, sentence length, and total syllables they have different weight factors.
The results of the two tests correlate approximately inversely. A text with a comparatively high score on the Reading Ease test should have a lower score on the Grade-Level test.
Flesch Reading-Ease (Target Score: >60)
In the Flesch Reading-Ease test, a higher score indicates that the content is easier to read and understand. While a lower score indicates that it is difficult to read. The formula to calculate the Flesch Reading Ease is as follows-
|100.00–90.00||5th grade||Very easy to read. Easily understood by an average 11-year-old student.|
|90.0–80.0||6th grade||Easy to read. Conversational English for consumers.|
|80.0–70.0||7th grade||Fairly easy to read.|
|70.0–60.0||8th & 9th grade||Plain English. Easily understood by 13- to 15-year-old students.|
|60.0–50.0||10th to 12th grade||Fairly difficult to read.|
|50.0–30.0||College||Difficult to read.|
|30.0–10.0||College Graduate||Very difficult to read. Best understood by university graduates.|
|10.0–0.0||Professional||Extremely difficult to read. Best understood by university graduates.|
Flesch-Kincaid Grade Level (Target Score: <8-10)
The Flesch-Kincaid Grade Level test is also using the same parameters as the Flesch Reading-Ease test to calculate the readability score but with different weight factors. The formula to calculate the Flesch-Kincaid Grade Level is as follows-
Why Readability Score Is Important In SEO (Search Engine Optimization)?
The readability number is important as it shows the content is easier and clearer to understand for the larger audience segment.
According to an article published here, “Readability is both a direct factor and an indirect factor for SEO. Good readability helps your target audience digest your content, thus influencing their behavior signals, which Google measures. Google prefers content with high readability that provides a satisfactory experience to the end-user.“

Definition Of Other Calculated Metrics
Total count of the words present in the given sentence or paragraph. The minimum number of required words for an article or post is 300 words.
A sentence is a set of words that are put together to mean something. A basic unit of language that expresses a complete thought. For a good readability score, make sure to form shorter sentences (less than 20 words).
SMOG Grade (Simple Measure of Gobbledygook) Or SMOG Index
The SMOG grade is a measure of readability that estimates the years of education needed to understand a piece of writing. SMOG is very useful for medical (health) writing and is considered the ‘gold standard’ formula in healthcare. It should be less than 8-10.
A complex word is a word made up of two or more morphemes. For example, blackbird (two root words). It is also defined as a word made up of more than three syllables. To improve the readability score, replace complex words with simpler ones.
Coleman Liau Index
The Coleman-Liau Index was created by Meri Coleman and T L Liau. The index doesn’t involve syllable counting but instead counted word length in letters. We use this index in the medical, translation sector, and legal sectors. It should be less than 8-10.
Here, L is the average number of letters per 100 words and S is the average number of sentences per 100 words.
ARI (Automated Readability Index)
The automated readability index (ARI) is a readability test for English texts, designed to gauge the understandability of a text. It relies on a factor of characters per word, instead of the usual syllables per word. It should be less than 8-10.
A syllable is a part of a word that contains a single vowel sound. It is pronounced as a unit. For example, blue, huge, right, etc.
Total count of characters including spaces.
Gunning Fog Index
The Gunning Fog Index was created by Robert Gunning, an American businessman. The index estimates the years of formal education a person needs to understand the text on the first reading. It should be less than 12.
|Fog Index||Reading Level By Grade|
|12||High school senior|
|11||High school junior|
|10||High school sophomore|
|9||High school freshman|
