A dynamic website is a set of web pages whose content changes dynamically. Dynamic websites access information in a database.

Dynamic websites use client-side scripting, server-side scripting, or both to create dynamic content. These websites also contain standard HTML code. For example, the Computer Hope homepage is a web page that changes daily to provide new content to visitors.

Client-side HTML scripting, the page may use JavaScript or other script to dynamically manipulate page data. Page rendering is determined by the parameters specified in the server-side script. In contrast, static websites require users to create pages in an HTML editor. Server-side dynamic sites require at least one request for data or other information, which increases loading time.

 ·  Security Vulnerabilities:

They contain serverside scripts and data interactions that hackers can target if security measures are not followed. Common vulnerabilities include SQL injection, cross-site scripting (XSS), and server insecurity. 

·  Cost of Hosting:

Dynamic websites often need a lot of client resources (CPU, memory, storage) to handle database queries and script execution. This can lead to higher hosting costs, especially for busy websites.

 

·  Complex SEO Implementation

Dynamically generated URLs may not be clean or SEO friendly compared to static URLs. Additionally, excessive use of JavaScript to create content prevents search engine crawlers from indexing your site properly.
