A huge number of jobs that are filled are never advertised to the public, or if they are, they’re filled by people who have a connection to the employer.
Your LinkedIn profile should leave no room for doubt about the kind of job you’re looking for and why you’re the best person for that position.
Your LinkedIn profile must be consistent with how you portray yourself elsewhere. Not only should your official résumé match the experience you list on LinkedIn, but it also should be consistent with Twitter and public Facebook information.
Make sure your LinkedIn profile has a targeted headline. Not only should the headline clearly state your career focus, it’s also the most important place to add a keyword or two, because this influences how you appear in search results
How do you want the world to see you professionally? What kinds of work do you enjoy doing? Why are you on LinkedIn? Those are the questions you should think about when creating your LinkedIn profile, so it’s aligned with your personal brand. While marketing-speak like 'personal brand' feels fake to many of us, we’re really just talking about setting the right tone for your profile and positioning yourself for the kinds of opportunities you’re interested in.
