The LinkedIn Skills & Expertise feature was launched in February 2011 and really took off when the endorsements were introduced on LinkedIn in 2012.
The Skills feature of a LinkedIn profile is one of the most often overlooked features, but one that is critical to anyone leveraging LinkedIn to develop a social network or look for a job/project. In addition to listing your education, languages and experience, the skills section can help your profile by adding tags that ensure your profile is more attractive to search engines and easier to locate for those using the LinkedIn search.
How can you identify or find skills? Go to: http://www.linkedin.com/skills/
To add skills to your profile, follow these steps:
1) Log in to LinkedIn
2) Visit the page for the Skills feature at http://www.linkedin.com/skills/your_skills
3) Search for and add up to 50 different skills to your profile. Note that when you find a specific skill, related skills are listed on the right side of the page. So if you search for ”social media” as a skill, you will also see related skills like blog, blogging, blogger relations, Facebook, Twitter, and YouTube.
4) Once you have added the appropriate skills, you can then view your profile and they should be listed just below the “Experience” section.
Although languages can be marked as a Skills & Expertise, I personally recommend the usage of the Language option on your LinkedIn profile as you then can indicate your proficiency. Especially in Belgium the level of knowledge of your languages is important and a real asset in an application.
