👋 Hey there, I'm Buli Goswami, a blogger and SEO enthusiast with hands‑on experience in content strategy and technical SEO. I've helped bloggers improve their organic traffic through content audits and strategic updates. I built this Content Decay Checker because I saw my own old articles losing traffic — and I wanted a simple, private way to fix them. Paste any post – it'll measure freshness, reading ease, word stuffing, and structure. Nothing is sent anywhere. Let's fix decay together.

📖 Contextual tools you might like: If you're optimizing content, you may also find our keyword density checker useful for analyzing term frequency, or our heading structure analyzer to improve your post's hierarchy. For a complete site audit, try our website SEO audit tool.

Here's a real blog post section we analyzed with the Content Decay Checker. See how fixing decay improved scores.

❌ Before (decayed)

📝 "In 2018, social media was different. Last year we saw changes. The best strategy for social media marketing in social media is to post daily. Really, social media requires constant attention. Social media platforms evolve fast."
↳ Outdated year, repeated "social media" 5x, long sentence.
🌿 Freshness 28/100 ⚠️ Outdated
🔁 Word repeats 45/100 ❗ Too repetitive
📖 Reading ease 52/100 ✂️ Long sentences

✅ After (updated)

📝 "Social media evolves quickly. In 2025, platforms reward helpful content. Posting daily still works, but quality matters more. Adapt your strategy based on analytics."
↳ Current year, synonyms, short sentences.
🌿 Freshness 94/100 ✅ Up to date
🔁 Word repeats 88/100 ✔️ Varied
📖 Reading ease 91/100 👍 Great flow
📚 Why this matters — backed by industry leaders:
💡 Result: After updating the post using the tool's tips, the blogger saw a steady increase in page views and better rankings. (Results vary, but fixing decay always helps.)

🔍 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.
