Take full advantage of your tagline
Instead of simply filling the field out with your current title, use the "professional headline" space to say something more exciting about your talents. For instance, if your official title is Marketing Manager, you could enhance it by tacking on several relevant (and legitimate) skills: "Marketing Manager, social media whiz kid, brand-builder."
Incorporate industry-specific buzzwords too, since that will help you show up in more searches. Recruiters rely on hyper-specific search strategies to narrow the field, according to Samantha Maldonado, manager of talent acquisition here at Thrillist. "Some people say that your profile should look like your resume. Whether it looks like your resume or it's short and sweet, I'm fine with it, [but] for me, more is better because I'm looking for keywords."
