Whether you like it or not, employers are searching for you online. In fact, according to an infographic from Career Builder, 37 percent of employers are using social networking sites to research job candidates. They frequent Facebook the most (65%), followed by LinkedIn (63%), Twitter (16%), and other sites (17%).

You probably realize that your chances of landing the job are hurt by anything negative they might find, such as inappropriate pictures, lies, discriminatory comments, or evidence of drug/alcohol use, but you might be surprised to find out that some of the discoveries employers make actually lead to an offer. Here’s what they’re digging deeper to find out:

1. Professionalism

Sixty-five percent of employers are looking at your social media profiles to see whether or not you present yourself professionally. This can be reflected in your profile picture, online interactions, shared content, photo albums, and more. If your profiles aren’t exactly made for an employer’s eyes, privacy settings can be your friend so you don’t come off as unprofessional.

2. Cultural fit 

Hiring managers also are looking at your online presence to determine whether or not you’re a good fit for the company culture. Because every company culture is slightly different, it’s hard to say exactly what they’re looking for — but by carefully researching the company before you apply, you can try to determine this yourself. After all, you’ll be happier if you land a job where you fit in well with the culture, too!

3. Qualifications

Employers are also looking to find out more about your qualifications. A resume only gives them so much insight into your background, skills, and interests. They may also compare the information in your resume to your online profiles to ensure it’s accurate.

4. Well-roundedness

Being “well-rounded” is also something 35 percent of hiring managers said they look for when searching candidate’s profiles. How much experience do you have in the skills you’ve listed? What types of job experience do you have? Do you have leadership or volunteer experience? What do your reference letters or recommendations say about you?

Think about it: What does your online presence tell potential employers about you?
