Common questions about Duplicate Content Checker
What is duplicate content?▼
Same/very similar content appearing in multiple URLs. Hurts SEO. Google penalizes (or ignores) duplicates.
Free checker?▼
Yes, 100% free. Compare two pieces of content. Get similarity percentage and matched phrases.
Acceptable similarity?▼
Below 20% safe. 20-40% review carefully. 40%+ duplicate concern. 100% identical = serious issue.
Internal duplicates?▼
Often unintentional. Tag pages, category pages, www vs non-www, http vs https. Use canonical tags to fix.
Manufacturer descriptions?▼
E-commerce common issue. Same product description as competitors. Rewrite uniquely. Add reviews, FAQs.
Plagiarism vs duplicate?▼
Plagiarism: copying others. Duplicate: same content multiple URLs (could be your own). Both bad SEO.
How Google detects?▼
Sophisticated algorithms compare phrase patterns. Even paraphrased content can be detected. Original always wins.
Fix duplicates?▼
Canonical tags, 301 redirects, noindex tag, content rewrites. Each situation different.
