A CV is your first foot in the door with either an employer or recruiter, and it is this which your merely judged on before progressing to the next step. You could have the ideal experience and skills for a role but if your CV doesn't match up you could see yourself rejected for the perfect job. 

With the use of LinkedIn you can upload work examples, links and even have references which will all build up your profile and give more of an idea to what sort of person they are dealing with.

Networking events are therefore another important aspect of getting a good profile behind yourself. Within an industry there will be past employers or colleagues that will be able to comment on your skills or personality and the more there are that know you the more people will find out about you - just make sure its positive!
