Readability

Flesch score 60-70: most readers। Web content: simple sentences, short paragraphs। Hindi content: shorter sentences even more important (Devanagari script denser visually)। Govt communications should be in simple Hindi — RTI Act promotes transparency।

Tips

15-20 words/sentence। Active voice। One idea per paragraph। Hemingway App (English), manual check for Hindi।

⚡ CalcWolf Insight

Amazon product descriptions target grade 6-7. Apple marketing copy averages grade 4-5. The most successful copywriters in history (David Ogilvy, Claude Hopkins) wrote at grade 6-8. Simple writing is not lazy — it is the hardest kind to produce and the most effective at persuading.
