According to LinkedIn, users who have their profiles completed 100% and done correctly are 40 times more likely to receive opportunities through LinkedIn, including job offers and new connections.

My experience in career development and LinkedIn jobs includes working one-on-one and learning what makes a difference, step by step, in finding what is needed to have a compelling profile and where the algorithms will find and match the profile with the best fit for them.
The search for results will be found when the profile is written for the algorithms and your potential opportunities and contacts.

I have written several books to help understand what needs to be considered in career changes, finding the right opportunity, and dealing with the many changes in this evolving world.  

Why Professionals use LinkedIn for Networking and More: Optimizing, Focusing, and Keeping Your Profile Current is a book that will serve you now and then again and again.
