Choosing an Effective Job Portal Simple Template

I am a job seeker. I need to post my Resume/CV on a certain job portal on the web where employers can view thus, increasing my chance of getting the best job.
However, upon browsing on the web, I have found a great number of free templates available. Now my question is, how can I chose an effective job portal template that will expose me to the most number of viewing employers? Any tips, strategies or techniques?
Thank you
