Have you spotted this new LinkedIn development?
It may not be an effective angle if everyone does it, but I believe there could be some real advantages in the next few months to the new features on the custom-designed job seekers package on LinkedIn.
You can highlight yourself as a 'Featured Candidate' to get to the top of the list in searches. And you get various other benefits, which could add that little bit extra which might make all the difference.
You can buy it monthly (I think their providing an annual purchase option seems a little lacking in faith in their own product) so it needn't be exorbitant.
Let me know how it works (or doesn't for you) and I can share the results with the community, anonymously. Being an early adopter often pays dividends. Have a look for yourself: click here.
