Wordpress, a well known blog platform, is an easy to use expandable Content Management System or CMS for do it yourself website design or professional developers.
We try to use Wordpress as much as possible when designing new website because of its ease of use. It is very easy to learn how to edit and update your own web pages.
Some people believe Wordpress sites are better for SEO, but there is no solid evidence of that. However, since the platform is very well made by developers who understand SEO and the importance of search, it is a much better starting point than most custom built websites where the developer may not have aa clue about what your business goals for the site are.
