Can you have duplicate content on the same website?

Internal duplicate content is when one domain creates duplicate content through multiple internal URLs (on the same website). External duplicate content, also known as cross-domain duplicates, occurs when two or more different domains have the same page copy indexed by the search engines.

Does duplicate content hurt SEO?

In general, Google doesn't want to rank pages with duplicate content. In fact, Google states that: “Google tries hard to index and show pages with distinct information”. So if you have pages on your site WITHOUT distinct information, it can hurt your search engine rankings.

What is considered duplicate content?

What is duplicate content? Duplicate content is content that appears on the Internet in more than one place. That “one place” is defined as a location with a unique website address (URL) - so, if the same content appears at more than one web address, you've got duplicate content.
