❌ 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 ↳ Outdated year, repeated "social media" 5x, long sentence.
🌿 Freshness28/100⚠️ Outdated
🔁 Word repeats45/100❗ Too repetitive
📖 Reading ease52/100✂️ 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.
🌿 Freshness94/100✅ Up to date
🔁 Word repeats88/100✔️ Varied
📖 Reading ease91/100👍 Great flow
📚 Why this matters: According to Google's SEO Starter Guide, keeping content fresh and readable is essential for search performance. A Moz study found that updating old content can boost traffic by 20–40% on average. This tool applies those principles automatically.
💡 Result: After updating the post using the tool's tips, the blogger saw a steady increase in page views and a better ranking in search results. (Results vary by site, but fixing decay always helps.)

🔍 What each score means (simple + examples)
🌿 Freshness score:Example: "In 2019, social media algorithms..." loses points. Historical article "Ancient Rome, 200 BC" gets tiny penalty (max 15). Years in quotes/code ignored.
📖 Reading ease:Example: "The implementation of advanced optimization strategies" → long sentence. Tool suggests splitting into shorter, clearer sentences.
🔁 Word repeats:Example: Using "digital marketing" 14 times in 500 words hurts score. Tool recommends synonyms to reduce repetition and improve flow.
📌 Structure:Example: Plain wall of text without headings → structure score 40. Add "## Why It Works" and bullet list → jumps to 85.
2 years of experience in blogging, content writing, and SEO. I built this Content Decay Checker because I saw my own old posts losing traffic – and I wanted a simple, private way to fix them. No tracking, no signup, just honest help for bloggers.
Content decay is the gradual loss of traffic and search visibility for an older blog post. It happens when information becomes outdated, readability suffers, or keyword usage becomes excessive. Our tool measures this with a clear score (0–100) and offers actionable fixes.
🧾 Does the Content Decay Checker store my content?
No. Everything runs locally in your browser. Even the 'Save report' function uses your browser's localStorage – no data is sent to any server. Your content remains completely private.
💰 Is this tool really free?
Yes, it's 100% free forever. No premium tiers, no credit card, no limits. If you find it useful, just share it with a fellow blogger – that's the only 'cost'.
📝 How do I use the tool effectively?
Simply paste your article into the text area, click 'Analyze now', and review the scores. The tool gives specific tips: update outdated years, shorten long sentences, reduce repeated keywords, and add structure. Save reports to track improvements over time.
🕰️ I write historical articles. Will the freshness score penalize me unfairly?
No. The tool detects historical context using words like 'ancient', 'century', or 'historical' and caps the penalty at a maximum of 15 points. Years inside quotes or code blocks are also ignored to avoid false flags.
⏰ How often should I check my old posts?
We recommend a quarterly review. Update dates, shorten sentences, add internal links, and refresh statistics. Regular maintenance keeps your content competitive in search results.
🧑💻 Who created this tool and why?
It was built by Buli Goswami, a blogger with 2 years of experience in SEO and content writing. Frustrated by seeing his own old posts lose traffic, he created this private, free tool to help other bloggers revive their content without any tracking or signup.
