Networking requires an investment of time, money and effort. Here are four ways to be sure your return on that investment is worthwhile.

Decide what you want

Why are your attending networking events? Are you looking for a new job? More business? Social contacts in a new home town? Whatever your purpose, stay focused on it, or things can slide into just another long lunch.

Attend the right event

If you are, say, a graphic designed looking for clients, why spend your time at an event for graphic designers? OK, you might be able to pick up some overload business from some designer who is super busy, but that's a very small poor to fish in. You'd be much better off mixing with folks from businesses who use design work. Seems obvious, but it's surprising how many people make this mistake.

Talk to the right people

Don't spend your valuable networking time chatting to people you already know, who ar not in your traget group. It's tempting, of course, because it's easy and funbut it's not networking! Look for new people and make the effort to meet and greet them.

Keep track of your results

Every month or so, track back through your networking opportunities. Who did you meet? Where did you meet them? How did they fit with your reasons for being there? Did anyone help you achieve your objective?

Of course, you'll also meet people who are pleasant additions to your social circle, some of whom may even become friends. Do include them in your success picture, but if you find you make more casual acquaintances than the people you are there to meet, you may need to change your networking activites so that they bring you a higher Return On Investment.
