Duplicate content is a common SEO issue that can hinder your website’s ability to rank effectively on search engines. Whether it’s accidental or intentional, having the same or similar content across multiple pages can confuse search engines and hurt your rankings. In fact, studies show that websites with significant duplicate content can lose up to 30% of their organic traffic.
But don’t worry—this guide will help you identify, prevent, and fix duplicate content issues to keep your SEO strategy on track.
What is Duplicate Content?
Duplicate content refers to substantial blocks of text that appear across different pages of a single website or between different domains. It doesn’t always mean an exact match—content that is “appreciably similar” can also be considered duplicate.
