1. The Science of Readability (Flesch-Kincaid)
Readability determines who can understand your writing. The Flesch Reading Ease score ranks text from 0 to 100. A score of 60 or higher is considered "plain English," suitable for 80% of readers. Highly technical documents often score below 30.
2. Sentence Length and Cognitive Load
The longer the sentence, the harder the brain has to work to process it. To maintain high engagement on the web:
- Maximum Length: Aim for under 25 words per sentence.
- Variety: Mix short, punchy sentences with slightly longer ones to create a rhythmic flow.
- Paragraph Density: Keep paragraphs under 3-4 sentences for mobile readability.
3. Modern SEO Word Count Standards
For a blog post to rank on the first page of Google, it must demonstrate Topical Authority. While short news bites can be 500 words, high-authority "Pillar Pages" usually range from 2,500 to 4,500 words. Google's AI models prefer content that answers every possible question about a topic.
