Why Readability Matters for SEO

Readability directly impacts user engagement, time on page, and bounce rate - all factors that can influence your search rankings. Content that's too difficult causes readers to leave, while content that's appropriately pitched keeps them engaged.

  • User engagement signals: Easy-to-read content keeps visitors on your page longer and reduces bounce rates - both signals Google considers for rankings.
  • Wider audience reach: The average American reads at an 8th-grade level. Writing at this level ensures your content is accessible to most adults.
  • Better conversions: Clear, simple writing is more persuasive. Complex content creates friction that reduces conversions.
  • Featured snippet optimization: Google often selects clear, concise content for featured snippets. Simple language increases your chances.

Target readability: For most web content, aim for a Flesch Reading Ease score of 60-70 (8th-9th grade level). Technical content can be higher, but rarely should exceed college level unless writing for specialists.
