Duplicate Content Checker

Find duplicate content across pages

About Duplicate Content Checker

Crawl your website to find duplicate and near-duplicate content across pages. Identify canonical issues, thin content, and content overlap that hurts SEO.

Frequently Asked Questions

How does duplicate content affect SEO?

Duplicate content confuses Google about which version to index and rank, dilutes link equity across multiple URLs, and wastes crawl budget. Google may also choose to rank a competitor's version instead of yours.

What is the difference between internal and external duplication?

Internal duplication is the same content on different URLs of your own site (www vs. non-www, HTTP vs. HTTPS, URL parameters). External duplication is when your content appears on other domains - either scraped or syndicated.

How do I fix duplicate content?

Use canonical tags to point to the preferred URL, implement 301 redirects for duplicate URLs, use the URL Parameters tool in Search Console, consolidate similar pages, and add unique value to syndicated content.
