People sometimes tell me they are disappointed that they are not getting many job leads from their networking efforts.  In response, I generally ask them how often they keep their network updated on their job search activities.  My point is that once you have created your list of contacts and reached out to them, don’t think that’s all you have to do.  In order to stay fresh in their minds for any potential job opportunities they may hear of, it’s essential you periodically follow up by keeping them in the loop on your progress (e.g., job leads, interviews, etc.).  Otherwise, they could very easily get distracted by their own responsibilities and forget about your job search altogether.  To avoid becoming a nuisance by over-communicating to your contacts, however, I generally recommend you limit your correspondence to every 4 weeks. 

If you have done that and you are still not getting any leads, you should expand your network (which you should already be doing) and consider broadening your search to include jobs where your experience, skills and interests are easily transferable.
