this is a good suggestion, increasing the chances to get an offer or anything is certainly good, but:

It seems to me that a lot (most?) of the head hunters on linkedin use a "shotgun approach" to recruiting where they basically just send you a message if you have a random matching keyword in your profile, ignoring actual details of your skills, ability to relocate/location, seniority, wage expectations etc. So you might easily get a full inbox, but going from that to a real position might not be trivial.
