This article will help you understand how to get better at copywriting through Flesch-Kincaid Readability Test is and how it can help your SEO campaigns and website.

What Is the Flesch-Kincaid Readability Test?

Flesh-Kincaid readability test is a readability score designed to identify how difficult to understand a text in English is. It was first developed in 190s by Rudolf Flesh, a consultant with the Associated Press. He developed methods for improving the readability of newspapers. Now, this is used by writers, marketers, researchers, policy writers, and advertisers to help them assess which content will be easily understood and engaged with.

There are two kinds of tests, the Flesh Reading-Ease, and the Flesch-Kincaid Grade Level. Below is the difference between the two Flesch readability scores:

1.   Flesh Reading Ease Scores

Flesch’s reading ease test is rated by considering word counts and sentences. It is straightforward and calculated based on two factors: the sentence length as arbitrated by the average number of words in a sentence, and the term length as judged by the average number of syllables in a word

Below is the mathematical Flesch reading ease formula:

Unlike in classical English literature in the 18th and 19th centuries, where the average sentence is longer, most modern-day text should contain shorter sentences to easily be understood.

Flesch reading ease is rated between 1 and 100, with 100 being the highest score. Thus, if your text receives a low score, it indicates that your content is complicated. For most business writing, a good Flesch reading ease score between 60 and 80 generally means that it can be understood by 12 to 15 years old.

Otherwise, you need to simplify your text. It could be longer paragraphs, a string of clauses connected with semicolons, or a lengthy sentence. Likewise, words that contain a lot of syllables can be harder to read.

2.   Flesch–Kincaid Grade Level

On the other hand, Flesch–Kincaid Grade Level tells you the American school grade can comprehend the material on your content. It is usually used in the field of education. This scoring system is primarily used by the U.S. by teachers, librarians, parents, and others to judge the readability level of books and other various reading material. It can also mean the needed years of education for a person to understand the material.

Flesch–Kincaid Grade Level can be calculated using the following formula:

Both Flesch-Kincaid reading ease and grade level use word length and sentence length. But unlike the Flesch Reading Ease score, the lower the grade level, the better and more understandable.

Does Flesch Reading Ease score affect Google rankings?

Having a good Flesch Reading Ease score is excellent for SEO and content. Google looks at the readability of content when ranking. It uses the Flesch Reading Ease Score to determine content readability. When crawling content, Google mimics how a human reads the content. It wants to read something straightforward and clear. Likewise, content writers should avoid bad practices like keyword stuffing or using hifalutin words.

In addition, searchers are likely to use common words and phrases when searching. For this reason, your content should contain not overly complicated keywords to try to meet a good readability score. Stick to the most common keywords related to your content.

Readability is not just crucial for ranking in SERPs. It also means a lot in voice search technology. Users using voice search are likely to get confused when listening to long articles and complex words and sentences. Difficult words won’t translate well in voice search. As such, your content will likely receive a lower rank.

Likewise, readability also affects your website’s retention rate. If your content is too complicated and hard to understand, people will likely leave your page and return to SERP to look at other sites. Likewise, suppose your text score is a very low grade. In that case, people will likely assume that your article is not valuable and useless. Both of these factors can affect your website’s bounce rate.

As such, it’s essential to optimize your content on your website and reflect excellent readability on your target audiences to maximize the benefits of content marketing.

How do I improve my Flesh Reading Ease Score?

  • Breaking long pieces of text
  • Inserting headings and subheadings
  • Keeping sentences more concise and simple

  • Altering long talks in the content
  • Using active voice instead of passive

However, content creators, digital marketers, and writers must remember to not only rely on Flesh Reading Ease Score when creating SEO-Friendly Web content.

They can easily understand content with a score of 60 or lower.
