The Flesch reading ease score: why & how to use it — Website Content Writers
If you use our readability analysis in the SEO plugin, you have probably come across the Flesch reading ease score. This score tells you how easy to read your text is. But how is the Flesch reading ease score calculated? Why is this score important for SEO? And, crucially, how can you use it to improve your writing? In this post, I’ll give you the answer to those questions.
The Flesch reading ease test measures the readability of a text. It uses two variables to determine the readability score:
- the average length of your sentences (measured by the number of words)
- the average number of syllables per word
Then, it provides you with a score between 0 and 100. A score of 100 means your copy is very easy to read. And, a score of 0 means your text is very difficult to read. You can see the exact interpretation of all the scores on the scale in the table below.
So, a text with a very high Flesch reading ease score is made up of short sentences, and it contains not too many two-syllable words. Conversely, a text with a very low Flesch reading ease score consists mostly of very long sentences and a lot of complex words.
The Flesch reading ease score in Yoast SEO
Yoast SEO also includes the Flesch reading ease score in its readability analysis. It looks at two aspects of your text:
- how the amount of words relates to the number of sentences.
- how the amount of syllables relates to the number of words.
If you don’t use too many difficult words and keep your sentences rather short, the check will pass. That means that you will get a green bullet if your text’s reading ease score is higher than 60. Why this number? Because, for web copy, reading ease of 60–70 is considered acceptable. Translated into simpler terms, that means that a good web text should be easily understood by a 13- to a 15-year-old student.
Why is the Flesch reading ease score important for readability and SEO?
It’s essential to take readability into account when writing web copy. Why? Because, if your text is too complicated, your audience might have trouble understanding it. Consequently, they may decide to leave your website and look for information elsewhere. As a result, you might get a high bounce rate that can lead to lower rankings in the long run. That’s why you should aim to write as clearly as possible.
Writing easy-to-read texts is also in line with holistic SEO. With Google’s algorithm becoming more human-like, and with the rise of voice search, readable texts are indirectly contributing to higher rankings.
While it’s important to write readable texts, it can also be quite tricky. This is because readability depends on a lot of factors. To help you write a copy that’s easy to read and understand, the readability section of the Yoast SEO content analysis runs all kinds of checks, among which is the Flesch reading ease score.
How to use the Flesch reading ease score to improve your writing.
We’ve come to the essential question. How can you use the Flesch score to improve your writing? Well, you write for an audience and you know your audience the best. Before you start writing or editing, think about what kind of texts fit your readers. Do you sell clothes or organize photography workshops? Or do you write for a mom blog or make step-by-step DIYs? In all of these cases, your content should be relatively easy to read since you are targeting a broad audience.
However, remember that you do not have to chase a high Flesch reading score at all costs. For example, you may write about complex, specialist topics for a specific, more knowledgeable audience. Or, perhaps you are an academic, blogging about your research? In those cases, it makes sense if the Flesch test produces a lower score.
Still, whatever your situation is, your text always benefits from a concise use of language. So, if you want to benefit from the feedback the Flesch reading ease score gives you, focus on two things:
1. Shorten Your Sentences to Index Faster.
Too many long sentences make your text difficult to read while short sentences keep the subject clear. When the sentences in your text are short, you allow your readers to absorb the information in your text. As a result, they don’t need to use all their attention trying to decipher what you want to say. That is why we advise you to break down long sentences, and your text will be much easier to read.
And please, don’t think that by using short sentences, you will dumb your text down. Let’s compare two short texts to show you what we mean. First, we have this sentence:
My favorite place to visit during weekends is my grandparents’ house near the lake, where we love to fish and swim, and we often take the boat out on the lake.
Did you find this sentence easy to read? Wasn’t it a bit too lengthy, confusing, and difficult to process? Breaking it into two or more sentences can make it much clearer:
My favorite place to visit during weekends is my grandparents’ house. It’s near the lake, where we love to fish and swim. We also often take the boat out on the lake.
These few short sentences are much easier to read. Yet, you give the exact same information as in the long sentence, so there is no dumbing down. Using short sentences keeps the subject clear and allows your readers to absorb the information you’re presenting.
2. Limit your use of difficult words
Words with four or more syllables are considered difficult to read, so try to avoid them where possible. Or try not to use them too much. For example, try words like small instead of minuscule, about instead of approximately, and use instead of utilizing.
If you want to reach a broad audience, you should also try to avoid using jargon. If you’re a medical expert, you’re probably familiar with terms like analgesic, intravenous, and oophorectomy. However, keep in mind that most people aren’t. When you can’t find a better alternative, make sure to explain it to users who might not know the word.
