Did you know that, according to CareerBuilder's 2016 Candidate Behavior Study, more than three in four full-time employed workers (76%) are either actively looking or open to new job opportunities?

That means in today's job market, you need to find a way to stand out among the competition and shine. To accomplish that, the first step is to get the person on the other end to sit up and pay attention to your resume instead of tossing it into a pile of "maybes."

One trick is to use certain keywords throughout your resume.

Keywords are descriptors of skills and attributes that industry insiders typically use to describe themselves and others in the profession. Hiring managers sometimes use computer programs known as applicant tracking systems — or ATS, for short — to save time and effort on their part.

Keywords matter when they're scanning your resume in these programs to gauge if your skill set is the right fit for an open position.

According to a Forbes article: "Depending on how a specific ATS works, the location and frequency of keywords within your resume can be extremely important. Typically, the better your resume matches the job description requirements, the higher you'll rank in the ATS. Additionally, it's common practice for companies to begin reviewing applicants from the top of the ranking list — bad news for job seekers who haven't customized and key-worded their resume."
