Your social media posts might win over or make you lose friends, but according to a recent CareerBuilder survey, they could also have a big impact on prospective employers. Seventy percent of employers use social networking sites to research job candidates (on par with last year), while seven percent plan to start. And that review matters: Of those that do social research, 57 percent have found content that caused them not to hire candidates.

The national survey was conducted online on behalf of CareerBuilder by The Harris Poll between April 4 and May 1, 2018. It included a representative sample of more than 1,000 hiring managers and human resource professionals across industries and company sizes in the private sector.

Who's Checking and Why?
Broken down by industry, those in IT* (74 percent) and manufacturing (73 percent) are more likely than those in retail/non-retail sales* (59 percent) to do social networking digging on potential job candidates. But it's not just the social sites that are fair game – 66 percent of employers say they use search engines to conduct their research on potential job candidates.

Nearly half of employers (47 percent) say that if they can't find a job candidate online, they are less likely to call that person in for an interview – 28 percent say that is because they like to gather more information before calling in a candidate for an interview; 20 percent say they expect candidates to have an online presence.

According to employers who use social networking sites to research potential job candidates, what they're looking for when researching candidates is:

• Information that supports their qualifications for the job: 58 percent

• If the candidate has a professional online persona: 50 percent

• What other people are posting about the candidate: 34 percent

• A reason not to hire the candidate: 22 percent

Content to be Careful About
As social media permeates all aspects of our personal and professional lives, what you post online can have serious and lasting consequences. Employers who found content on a social networking site that caused them not to hire a job candidate said these were the primary reasons:

• Job candidate posted provocative or inappropriate photographs, videos or information: 40 percent

• Job candidate posted information about them drinking or using drugs: 36 percent

• Job candidate had discriminatory comments related to race, gender, religion, etc.: 31 percent

• Job candidate had poor communication skills: 27 percent

• Job candidate bad-mouthed their previous company or fellow employee: 25 percent

• Job candidate's screen name was unprofessional: 22 percent

• Job candidate shared confidential information from previous employers: 20 percent

• Job candidate lied about an absence: 16 percent

• Job candidate posted too frequently: 12 percent

On the other hand, those that found content that led them to hire a candidate said it was because they saw:

• Job candidate's background information supported their professional qualifications for the job: 37 percent

• Job candidate was creative: 34 percent

• Job candidate's site conveyed a professional image: 33 percent

• Job candidate was well-rounded, showed a wide range of interests: 31 percent

• Job candidate had a large number of followers or subscribers: 18 percent

The Monitoring Doesn't Stop Once on the Job
Employers continue to monitor employees' online presence even after they're hired. Nearly half of employers (48 percent) say they use social networking sites to research current employees—10 percent do it daily. Further, a third of employers (34 percent) have found content online that caused them to reprimand or fire an employee.
