A suitable photo
Appearance should not be your first priority when in search of employment. But when it comes to a purely professional environment like LinkedIn, where there is no direct personal interaction, your profile picture should be appropriate, serious but not pretentious, and professional. It’s important not to get carried away by the more relaxed posts that one finds on other social media platforms, such as Instagram or Facebook.
Make your profile public
This is very important because if you don’t make your profile visible to third parties, then you automatically "cut off" other professionals from viewing it and contacting you, and this defeats the purpose of joining the specific channel, which is to connect with the business community.
Use English
It’s probably best that your profile information be written in English, as it’s the language that will allow the content of your page to be understood by all users who visit it, regardless of their country or nationality. It goes without saying that that you need to have a very good command of the language,to avoid grammatical or wording errors, and to clearly and accurately describe your skills, experience and your entire professional career.
Describe yourself in a clever way
The cover letter is your opportunity to make a good first impression. The outline appearing at the top of your profile, you should briefly include your professional qualities that will grab the visitor's attention and focus, using keywords related to your subject and today’s labour market.
You’ll be able to provide detailed information about your profession and your career, your expertise, the companies you’ve worked for or the skills that make you stand out in other, more appropriate sections of your profile.
Network
Connect with market professionals, follow the pages of companies that interest you, not necessarily to work for them but because they are leaders in their field - or join professional groups that will help you stay up-to-date on developments in your field.
LinkedIn is a tool that can open up many opportunities if you use it properly. It's a whole new world, so you need to devote time to explore it and familiarize yourself with its potential.
