In simplest terms, static Web pages are those with content that cannot change without a developer editing its source code, while dynamic Web pages can display different content from the same source code. When it comes to using static or dynamic pages for parts of your company's website, having the most advanced code on each of your pages is not important. What is important is the purpose each page serves for your website.
Static Web pages display the exact same information whenever anyone visits it. Static Web pages do not have to be simple plain text. They can feature detailed multimedia design and even videos. However, every visitor to that page will be greeted by the exact same text, multimedia design or video every time he visits the page until you alter that page's source code. Static websites are popular because they are super efficient, extremely fast and usually free to host. Blogs, resumes, marketing websites, landing pages, and documentation are all good candidates for static websites.
