What is a Good Readability Score and How Do You Improve it?
Writing good SEO content isn't about connecting sentences and words – it's about making people understand what you're trying to say. Readability is a great marker that all skilled writers use to optimize their content and achieve their SEO ranking goals.
Readability shows how easy or difficult it is for your reader to read and understand your written content. How a writer presents a text sets the standard for what readers can expect in the future, allowing them to determine whether that content source suits them.
Knowing what is a good readability score and how to write at a higher grade level will help you land on the first page of Google and reach your target audience easily. We will help you understand how to increase your readability score by teaching you about the factors that influence it and all the tools you can use to improve it.
What is a Good Readability Score?
Generally, when you learn what content writing is and how to excel at it, you learn about making your text readable. A good readability score of 60 or higher indicates that your writing is relatively easy to read and understand. Most top Google pages have the average Flesch Reading Ease score between 45 and 60, indicating that the content has been checked for readability.
When your content writing has a good readability score, it can be consumed by the general public. The goal is to produce content that is easy to understand for those with limited knowledge of the topic as well as informative enough for those who are experts on the topic covered.
Understanding Readability Scores
Using a readability score checker won't solve your problems. You need to understand what a readability score is to make the most out of your writing.
Readability measures the reading difficulty of a piece of text, and its complexity depends on factors such as grammar, syntax, text formatting, etc. Your content's readability determines whether the text is suitable for both beginners and those experienced on a certain topic.
Ways To Calculate Readability Score
Many AI software, plugins, and applications can calculate readability scores in seconds. However, all of them are based on formulas such as the ones from Flesch Reading Ease and the Flesch-Kincaid Grade Level.
Rudolf Flesch developed two tests that set a standard for readability testing: The Flesch Reading Ease Test, and the Flesch Kincaid Grade Level Test. These tests use a trusted and reliable method to calculate readability scores manually with specific formulas.
By counting the average number of syllables, and words and finding the average sentence length, you can check the score, and know each grade's (U.S school level) reading difficulty when reading your written content.
Another way to calculate readability is by using AI tools. You can use an SEO readability tool, plugin, or application easily and get an accurate number score. The checkers use AI to analyze the text thoroughly and inspect every word and sentence before suggesting improvements such as grammatical errors, wrong words, and rewriting entire sentences.
The problem with using AI for writing text or checking its readability score is the lack of personal touch. AI can generate endless suggestions, but most won't sound human enough for your readers to comprehend or relate to. That can affect your readability score or rather cause it to be lower than needed.
Readability Score Formulas
The Flesch Reading Ease formula is based on determining the average sentence length and the average number of syllables per word in a text. The given formula is then used to calculate a number, which is later interpreted with a score from 0 to 100. The formula in question is:
206.835 – 1.015 x (total words / total sentences) – 84.6 x (total syllables / total words)
Use this formula to do the Flesch Kincaid reading ease test and calculate the score manually, then check the interpreting table below for the readability score results. As for the Flesch Kincaid Grade Level formula, it looks like this:
0.39 x (total words / total sentences) + 11.8 x (total syllables / total words) – 15.59
The generated or formulated score marks your content's reading difficulty, ranging from 0 to 100. The higher the score, the easier the text is to read and understand. A score below 50 signifies the need for improvement, but you must ensure that the changes you make keep the text understandable for all target readers.
After calculating the score, the matching correspondence should determine the reading difficulty from "very easy" to "very difficult." Match the correspondence to your target audience and aim for a score that matches their profile and reading abilities. Here's a bit more on the level of readability you should aim for depending on your target audience:
| FRE Score | Grade Level | Reading Difficulty |
|---|---|---|
| 90-100 | 5th grade | Very easy to read |
| 80-90 | 6th grade | Easy to read |
| 70-80 | 7th grade | Fairly Easy to read |
| 60-70 | 8th and 9th grade | Standard |
| 50-60 | 10th to 12th grade | Fairly difficult to read |
| 30-50 | College | Difficult to read |
| 0-30 | College Graduate | Very difficult to read |
Factors That Influence Readability Scores
Knowing what is a good Flesch reading score and doing the test on your text can give you some insight into the quality of your writing, but you'd have to do further work if the content doesn't meet your SEO or target audience goals.
Understanding the components that affect readability will help you learn how to improve your readability score and raise it to the highest level possible or even how to lower your readability score, or do whatever it takes to make the score fit your needs and your audience. These are the influential factors that are game-changers when it comes to improving content writing and reaching target SEO scores:
- Writing Style and Tone: The writing style and tone highly affect the readability score and can change a reader's outlook on your content. A formal tone will lower the score and make a text more difficult to read, so avoid it if you want to achieve an average readability score. Likewise, the active voice is easier to read and understand, so many AI tools suggest using the passive voice over the passive voice. Adjust your tone depending on the type of content you're writing, and the score will reflect your target reader's comprehension level.
- Vocabulary and Word Choice: Proper word choice will improve SEO and reduce the bounce rate by engaging the target readers and making them interested in your content. Your content must contain vocabulary that fits the topic and is familiar to your target audience. If the vocabulary is too formal or informal, the text becomes useless to the reader and significantly affects the readability score.
- Sentence Structure and Complexity: Well-written text with a natural flow, clear structure, and appropriate sentence length will help you get the desired readability score. If the score is higher or lower than expected, adjust the complexity and the number of words, shorten your sentences, and fix your writing tone to get the desired outcome. Organizing the text and balancing the structure with separate paragraphs, headings, subheadings, and bullet points will also help you increase readability and generate a higher score.
Evaluating Readability Scores
Every type of writing done in the English language goes through some analysis that determines its readability score. It could be an editor reviewing the text or the writer running it through an analysis tool. Both are valid options, with countless tools and resources suitable for the occasion.
Using Readability Tools and Resources
An adequate online readability score checker can help you determine what is the best readability score for your type of content while providing enough information for further improvement on the piece of text. There are a lot of AI applications and plugins that suggest changes during your writing session, helping you ease readability and get the desired score. Here is an overview of some of them:
- Grammarly: This AI-based writing tool reviews grammar, spelling, and sentence structure, detects plagiarism, and suggests error replacements. You can install a Grammarly plug-in into any platform you work on, and it will act as your assistant. Grammarly can also quickly determine the readability score for your text, while you can refer to its small readability guide for improved writing.
- Hemingway Editor: The Hemingway Editor application highlights complex sentences that you can improve to make the text easier to read. This advanced spell checker works with AI to suggest writing improvements, focusing on how your readers perceive and consume your text. The app highlights readability issues and helps you achieve the desired score to attract your target audience.
- Microsoft Word: As the biggest and most popular writing platform, Microsoft Word helps writers produce quality content with their built-in readability statistics tool. This tool is based on the Flesch Reading Ease and Flesch Kincaid Grade Level Tests and uses their scoring system to calculate the readability score and assist writers. You can use Microsoft Word to pick the right words and adjust sentence length to get the desired score.
Using Manual Assessment Techniques
Before AI and the progressive digital age, readability scores were calculated manually using various text assessment and analysis formulas. These formulas use word and sentence length and syllable count to calculate the readability score, determining the reading difficulty of a given text compared to educational levels or an age group.
Simple Measure of Gobbledygook (SMOG)
SMOG was created by psychologist Harry McLaughlin, who wanted to create the most reliable readability formula. This formula measures the years of education a person must have to understand a certain text, known as the SMOG grade.
The grade is calculated with a text of 30 or more sentences, considering the number and complexity of the polysyllabic words. The complexity of the polysyllabic words determines the SMOG grade, reading difficulty, and grade level.
Gunning Fog Index Formula
Robert Gunning invented the FOG Index, blaming the difficulty of student materials on too much "fog" or unnecessary complexity. Gunning believed in simplicity – short sentences lower the "fog" and transmit the writer's message more clearly.
The calculation process involves counting the average number of words and sentences, complex words, and sentence length in a text. The Fog Score ranges from 6 to 20, which equals grade levels from the 6th grade to postgraduate students.
Coleman-Liau Index Formula
Meri Coleman and T. L. Liau invented this assessment formula to improve the readability of English textbooks in public schools. Compared to other formulas, the Coleman-Liau Index uses computerized grading and considers characters (letters) instead of the average number of words and syllables.
This formula determines readability by calculating the average number of letters and sentences per 100 words, generating the average score. The scores range from 5 (5th grade) to 17 (professional), revealing the corresponding reading difficulty.
Practical Applications of Readability Scores
Achieving a good readability score will make your content easy to read and understand. Knowing how to communicate with your target audience easily will contribute to higher SEO scores, lowered bounce rates, and higher interest in your writing, no matter what type of content you're putting out.
