Flesch reading ease score: Use it!

Flesch reading ease score: Use it!

If you use our Content Analysis Tool in the Yoast SEO plugin, you may have come across the Flesch reading ease score. This score tells you how easy your text is to read. But how is the Flesch reading ease score measured? And why is this score important for SEO? In this post, I’ll explain the importance of readability for SEO and how the Flesch reading ease test works.

In the readability tab of the Yoast SEO meta box, we run all kinds of checks to help you write copy that’s easier to read. You’ll find the Flesch reading ease score there, among the other checks.

Why is readability so important for SEO?

It is unclear whether readability is a specific ranking factor. Therefore we don’t know if Google uses tools like the Flesch score (or a variation of it) as a ranking factor in its algorithm. However, we do know that, from an holistic SEO perspective, readability is very important.

SEO copywriting training Info
If your text is too complicated, the text will be too hard to read for your audience. This might scare them off and make them search elsewhere for information. Impenetrable text will result in a high bounce rate, leading to a lower rank in the long run. So, you should make sure your articles are well written and not too difficult to read.

What does the Flesch reading ease test measure?

Flesch reading ease measures the complexity of an English text. But since the release of Yoast SEO 3.5, we also provide reliable scores for several other languages too.

The lower the score, the more difficult the text is to read. The Flesch readability score uses the average length of your sentences (measured by the number of words) and the average number of syllables per word in an equation to calculate the reading ease. Text with a very high Flesch reading ease score (about 100) is straightforward and easy to read, with short sentences and no words of more than two syllables. Usually, a reading ease score of 60-70 is considered acceptable/normal for web copy.

    Honestly, I don’t care for the reading score. I organize the articles in subheadings and sub-section when I feel the need to do so.

      I think that the Flesch reading score is important on every text on your website. Every text should be well readable!

    Nice article, but how does this work with other languages? I always seem to get a hard to read Flesh score when writing articles or pages is Dutch.

    What’s your take on this?

      I was wondering the same. I allways have a bad score at this and after erading this article, one thing got cleared out. It is nor reliable in other languages, thus i won’t take it into account next time a write a post because my language is romanian. Even when i write in blocks with headings and stuff it seems that the etxt is hard to read tough it doesen’t really look like that. Great info because now i can exclude the flesch ease score and focus on more important aspects.

        It is too bad that you can only use it in English. We are currently working on some other checks that will be appropriate to use in other languages as well. It will take a little while though!

      The Flesch is designed for English. As you can imagine, syllables in English are different from syllables in Dutch. The Flesch in the Page Analysis just does not measure syllables correctly in Dutch. I would not say that the score is completely useless for Dutch texts, but I cannot say what kind of bias it has.
