For students heading into the job market, social media can have a huge impact on whether or not they land the job of their dreams.

According to social media monitoring company, Reppler, nine out of 10 employers will check the social media profiles of potential employees.

Lindsey Sirowy, the senior account executive of digital for OCG PR, says it’s important to clean up your social media footprint when looking for a job.

She recommends doing a Goggle search for your name to see if there’s any old social media profiles you may have forgotten about.

“See what’s popping up under your name,” Siroway said. “And with that, make sure that you follow those links and say, ‘Where is this image coming from?’”

Career Services Executive Director John Thompson III said it’s some of the less obvious things students need to be aware of. Humor and sarcasm can be misinterpreted. Also, profanity is often frowned upon, whether it comes from the owner of the page or friends.

“Keep a really good image about yourself and your friends,” he said “Because they’re going to judge you by the people you hang with.”

An increasing number of colleges are also using social media to screen applicants.

While admissions counselors don’t check the social media profile of every student that applies to TCU, Director of Freshman Admissions Heath Einstein said his office will use social media to investigate students if they have reason to suspect their behavior could be unbecoming of the university.

His recommendation? Use the grandmother rule.

“Is this something you would want your grandmother to see?” he said.

Freshman business major Nolan Bagwell admitted to having some questionable content in his social media profiles. He said he hadn’t thought about how that might affect him in his job search after college.

“I’ll probably just delete my Facebook and my Instagram when I get to that point,” he said.
