This article shows you the key differences of a Website and a blog.
Website
A Website is a collection of Webpages. These Webpages are hosted on a Webserver. You can access the Website (and its Webpages) with your browser by using an address like www.ebay.com.
Static Website
The content of a static Website does not change unless it is manually updated by the webmaster.
Blog
A blog (comes from web log) is a specialized Website! A blog is normally updated on a regular basis with new content, the so called posts.
The differences between a blog and a static Website
The major difference between a blog and a static Website is the content management.
The content of a static Website is not updated on a regular basis. Normally the webmaster only can change it.
The content of a blog is modified on a regular basis by one or more authors. The author can write posts with a simple user interface. A blog provides a comment system, an exchange between the author of a post and the readers can take place.
A blog has normally a better ranking than a static Website in the search engines. The reason for that is the changing and growing content.
Improvement of a static Website
You can integrate a blog in a static Website in order to add the functionality/benefits of a blog to your static Website.
Dynamic Websites
