Whether you are a passive or active job seeker, I recommend completing your LinkedIn profile with your primary skill sets. 

This way, if a recruiter is searching for your specific skills, your profile will appear in search results. 

Without this information, you may remain hidden, miss out on understanding the market, and not have the opportunity to assess your value. 

Even if you are not actively seeking a job change, you never know what might catch your interest and lead you to consider a new opportunity.

Happy job searching!
