Importance of professional website to search committees
I look for and use the websites of job candidates all the time, and I know many of my colleagues do as well. The reason is that we can find things there that are not on your CV, for example:


Links to the PDF versions of your papers, if you put them there.
Links to pages that provide teaching materials for your students.
Numerous other things that belong on a website but can't be obtained through the CV itself.


So yes, do create a website. As @aeismail writes, take a look at the websites of your colleagues in the field, pick the ones you like best, then imitate that style.

What system you use -- handwritten HTML or a content management system -- is secondary to the content you put online.
