📌 What is Plagiarism Checker?

The Plagiarism Checker is a powerful content originality verification tool that scans your text against billions of web pages, academic papers, and published articles to detect any duplicate or copied content. Whether you are a student submitting an assignment, a blogger publishing an article, a journalist writing a story, or an SEO professional creating web content, plagiarism can have serious consequences — from academic penalties to Google ranking drops due to duplicate content issues.

🎯 Why It Matters for SEO

Duplicate content is penalised by Google. Pages with over 25-30% duplicate content from other indexed pages may be filtered from search results. Every published piece should pass a plagiarism check before going live.

📋 How to Use This Tool
