Some job seekers only look at Indeed.com or some other job search website to find jobs. That could be a big mistake to limit job searching to only those site. The thinking is that Indeed already scours the internet for jobs, so why do it your self.
While Indeed is good, it does not cover every site.
You may be missing some big leads. Try going to CareerBuilder or Montster directly for job searches and you will find that Indeed, does indeed miss many searches.
