LinkedIn has evolved to become one of the most essential networking tools for young professionals in virtually any field. When used correctly, LinkedIn is a great resource with few, if any, drawbacks.

It’s important to understand that a LinkedIn profile will be judged by employers and other professionals in nearly every aspect. Not only is it essential to develop a professional profile that creates a personal brand image, but also ensure the profile photo is appropriate.

Ann Thye, apparel, merchandising and design adviser, said LinkedIn is no longer a “maybe,” but a “must” in the internship and career search.

“How you present your personal brand is key through the photograph, and through the words you use to present yourself,” Thye said.

The last few years have seen a rapid change in the way recruitment and networking is done. Some may even hire professional photographers specifically for LinkedIn photos.

“In most cases, I would say a shot that is above the waist, or what is sometimes called a bust shot, smiling and welcoming, plain background, and with open posture is most welcoming,” Thye said. “No distracting jewelry, and a professional look.”

Thye also said to not use a cropped photo or a picture from a party. It’s also not a good idea to use a selfie as your profile photo.

Kalli LeVasseur, associate for fashion, beauty and lifestyle LA based public relations company, Post+Beam, said provocative and revealing clothing is the biggest mistake.

LeVasseur also said that long-armed selfies and mirror pictures should be avoided. When it comes to what should be worn in the profile photos, consider the specific industry. For those in the fashion industry, a riskier outfit is often accepted.

“I work in fashion, so someone who is well-dressed and on trend is impressive to me. A recruiter in another industry might not appreciate the same fashion risks I would,” LeVasseur said.

Besides helping run the showroom and managing clients, LeVassuer also coordinates the Post+Beam internship program. She has not had the opportunity to do any specific recruiting yet, but she has interviewed potential interns.

While the cover letter is often the most crucial element for PR professionals, LinkedIn is close behind. It provides a space for candidates to present their most professional self, and employers expect that, LeVasseur said.

Although hiring a professional for a LinkedIn photo can show commitment, it’s important that professionalism is reflected across all social media platforms.

“I do think it shows you were willing to go the extra mile,” LeVasseur said. “However, you don’t want a potential employer to then find the exact opposite types of images of you when they Google search your name or check your Instagram account.”

Building a professional profile with an appropriate photo is the first step to leaving a lasting impression on potential connections.

“Because LinkedIn is for making professional connections, I do think having a photo that reflects that is important,” LeVassuer said. “It’s about putting your best self forward, just as you would in an interview and on the job.”
