Duplicate content can be a problem for a website because it can confuse search engines and make it difficult for them to determine which version of the content is more relevant to a particular search query. As a result, a website with a lot of duplicate content may not rank as well in search results.
That being said, it’s important to note that some amount of duplicate content is normal and not necessarily a problem. For example, it’s common for websites to have similar product descriptions or to use the same content in different sections of the website.
It’s only when duplicate content becomes excessive and/or is used to manipulate search engine rankings that it becomes a problem. If you’re concerned about duplicate content on your website, you can use tools like Copyscape to identify and address any issues.
