Frequently Asked Questions (F.A.Q) for Duplicate Content Checker Tool

What is duplicate content and why does it matter?

Duplicate content is any text that appears in more than one place on the web or within your own site. Search engines may struggle to decide which version to rank, which can dilute your SEO power or even result in ranking drops.

How do I use this tool?

Just choose your comparison mode (URL vs URL, URL vs Text, or Text vs Text), enter or paste your content, and click “Check for Duplicate Content.” You’ll get a similarity score, a list of repeated sentences, and plain-English SEO tips.

Is my data safe?

Yes! All checks run in your browser. We don’t store, share, or index your content—your privacy is 100% protected.

Can I check unpublished or draft content?

Absolutely. Use the Text vs Text or URL vs Text mode to paste any draft content and compare it to live pages, categories, or other drafts.

What’s a good similarity percentage?

Ideally, your content should be under 20% similarity with any existing page, especially for important SEO pages. Our tool gives you guidance on what needs rewriting.

Does this tool check the entire internet?

No—it compares only what you input (pages or text you provide). For a web-wide scan, consider a professional tool like Semrush or [Copyscape].

Can I use this to find plagiarism?

Yes! It’s useful for checking for plagiarism, spun content, or content syndication. However, it’s designed for on-site SEO and content audits.

How often should I check for duplicate content?

Any time you add new pages, merge categories, or repurpose old articles. Regular checks help keep your site unique and ranking strong.
