Dynamic Content is content of a website that changes based on data or input from the user. Dynamic Content is often used to generate pages on e-commerce sites, where data from the user’s previous purchases and search history determine what products are shown on the page. Search engines are working to better handle Dynamic Content, but there are still some SEO issues associated with search engine crawlers not indexing dynamic content because it appears to be duplicate content or that the complicated link structure slows down the system.
