Indeed, I am on the same thought as Timothey, it very much depends on what kind of job you are looking for.
In most cases though, having some mutual contact to the person hiring in the company you would like to work in makes the most impact on actually securing a job. If you have a good many connections on LinkedIn built up you can look for mutual connections when you find the hiring manager at a company you like.
