Frequently asked questions
What readability score should I aim for?
For general audiences, target a Flesch Reading Ease score above 60, which corresponds to roughly an 8th-grade reading level. Technical and academic writing can target lower scores for specialist audiences.
What makes text hard to read?
Long sentences, complex words with many syllables, passive voice, and dense paragraphs without breaks all increase reading difficulty.
Does readability affect SEO?
Yes. Search engines favor content that matches the reading level of the target audience. Content that is too complex or too simple for its topic can underperform in rankings.
What is the Gunning Fog index?
Gunning Fog estimates the years of education needed to understand a text. A score of 12 means a high school graduate should understand it. Aim below 12 for broad audiences.
