🔍 What each score means
- 🌿 Freshness score: "In 2019, social media algorithms..." loses points. Historical articles get tiny penalty (max 15). Years in quotes/code ignored.
- 📖 Reading ease: "The implementation of advanced optimization strategies" → long sentence. Tool suggests splitting into shorter sentences.
- 🔁 Word repeats: Using "digital marketing" 14 times in 500 words hurts score. Tool recommends synonyms.
- 📌 Structure: Plain wall of text without headings → score 40. Add "## Why It Works" and bullet list → jumps to 85.
