There is the general SEO rule for readability of your article is that when writing for a general audience; you should aim for an 8th grade reading level. This will not only help your article to get out to people who are less educated, it can reach customers who are learning English as a second language. And, in general, it can help you stick to simple sentences that are clearer and more easily understood at a glance.
But how do you know if your article is easy to read and understand to 8th grades? There is a technique called Flesch Reading Ease scoring system. If you score above 60 means you are good to go in readability part.
The Flesch Reading Ease Readability Formula
The specific mathematical formula is:
- RE = 206.835 – (1.015 x ASL) – (84.6 x ASW)
- RE = Readability Ease
- ASL = Average Sentence Length (i.e., the number of words divided by the number of sentences)
- ASW = Average number of syllables per word (i.e., the number of syllables divided by the number of words)
The output, i.e., RE is a number ranging from 0 to 100. The higher the number, the easier the text is to read.
- Scores between 90.0 and 100.0 are considered easily understandable by an average 5th grader.
- Scores between 60.0 and 70.0 are considered easily understood by 8th and 9th graders.
- Scores between 0.0 and 30.0 are considered easily understood by college graduates.
The following table is also helpful to assess the ease of readability in a document:
- 90-100 : Very Easy
- 80-89 : Easy
- 70-79 : Fairly Easy
- 60-69 : Standard
- 50-59 : Fairly Difficult
- 30-49 : Difficult
- 0-29 : Very Confusing
