To improve SEO and eliminate duplicate content, the HTML text needs to be rewritten. All class and CSS style attributes should be removed from the HTML. This will ensure that search engines see unique content and improve your site’s ranking. The process will involve analyzing the existing HTML and rewriting the content to convey the same information without duplicated text or relying on class and CSS styling for content structure. This rewritten HTML will focus on the semantic meaning of the text and its overall structure.
