While the possibilities may seem endless, not every employer is Online and therefore is not checking sites where digital resumes can be submitted. A good way of overcoming this obstacle in order to have your digital resume seen by those employers is to network, as suggested by Susan Ireland. Here's a little video posted by AARP that basically explains the in's and out's of networking (excuse the sponsor message!)
There is always a way to optimize your digital resume so that it is seen by the particular employer/company you are hoping to be hired by. A huge number of companies are shifting to using digital resumes if they don't solely use digital resumes, it is a safe assumption that your digital resume would only serve as a bonus.
My digital resume is formatted as a magnet resume meaning that it is a resume for all my prospective jobs rather than for one in particular and thus doing both networking and posting it on various resume sites would prove helpful. As I progress on creating my digital resume I am realizing how incredibly helpful the research I have conducted is. There are many fields of the digital resume that would have been a struggle for me to complete to my greatest advantage and since I have taken into consideration comments from a number of resume experts my experience is moving along smoothly. I suggest to anyone embarking on creating a digital resume to do their research!
