To let recruiters or your entire LinkedIn network know you're actively looking for a job: Go to your profile from the menu or the home page; Just below your general presentation, click on the frame “Inform recruiters that you are available”; Fill in the title of the desired position, the place, the type and the date on which you can start working; To finalize your ad, choose who can see it. You have the choice between all the members of your network or only the recruiters. If you are not already under contract with a company or if it is aware of your approach, the first choice is recommended. Otherwise, don't make the mistake and opt for recruiters only!
