Duplicate Content
Duplicate Content involves substantial blocks of identical or very similar content appearing on multiple webpages within or across different domains. This issue can arise from technical problems, such as multiple URLs pointing to the same page, or from intentional copying (compare black hat SEO). Duplicate content may negatively impact a website's ranking on search engines, as Google and other search engines may struggle to determine which version is the original or most relevant. Avoiding duplicate content involves using canonical tags, setting up proper redirects, and ensuring unique and valuable content across all pages.
