If you spend hours tweaking, buffing and polishing your resume to create the ultimate career marketing tool, you may be inclined to let it sit peacefully in Monster's database of resumes and never touch it again unless you're trying to change jobs or responsibilities. But here are five compelling reasons you should revisit this critical document on a regular basis.

Reason #1: Recruiters Can Search by Date

Recruiters have a number of ways to sift through the millions of resumes in Monster's database. One way is by viewing the most recently updated resumes first. So if you would prefer to be the third resume that pops up -- as opposed the 103rd -- updating your resume frequently is something easy you can do about it.

Another way to get your resume to the top of the virtual heap is to simply renew your resume. Just log in to your account here and click the Renew link under the title of your searchable resume.

Reason #2: The Job Market Is Always Changing

Our economy and the jobs created by it are fluid, varying from month to month and state to state. These changes in the job market could influence which skills and accomplishments you want to emphasize or which places you indicate you're willing to relocate to on your Monster resume. To keep tabs on the hiring activity in different locations and fields, keep your eye on the Monster Employment Index. This can be one way to measure which sectors and regions are creating the most jobs.

Reason #3: Your Resume Is a Work in Progress

Your resume reflects your skills, capabilities and career accomplishments. As you evolve, your resume should evolve, too. Like many things, if you make a point of updating your resume frequently, it will prove to be much easier on you in the long run.

Reason #4: You Can Experiment

If you're willing to revisit your resume on a continual basis, this frees you up to do some experimenting and testing. You can tinker with the resume title and job descriptions, and then come back to your My Monster account to see how the changes impact the number of times your resume is viewed by employers with access to Monster's resume database.

Reason #5: Language Changes

Even if your skills and accomplishments haven't changed, it's possible that some of the terminology used to describe them has. This is particularly true in fields that are touched by technology -- and most fields are these days. As such, it makes sense periodically to go through your resume with a fine-tooth comb to make sure the terms you use are accurate and up to date.
