Features per language

Most of the content checks in Yoast SEO work for every language. It just doesn’t matter if you’re writing Dutch, English, Romanian or Afrikaans. In virtually all languages we can recognize if your focus keyphrase has been used in the first paragraph, if you’re using enough words, and if you specified a meta description.

However, some checks are language-specific, and some of the checks behave differently for different languages. That’s simply because languages happen to be different. In the table below, you’ll find a list of language-specific features and the languages they’ve been implemented for. Below that, you’ll find more specific information on how the readability analysis differs across languages.

Language-specific variations of the readability analysis

What constitutes a good writing style is different in every language. That’s why we fine-tune our readability analyses for each language. For this, we use style guides written for that specific language, or formulas that were specifically developed for that language. Here, you can find out exactly what that leads to. If your language isn’t mentioned, it follows the default analysis.
